Usefulness of ultrasonographic techniques in catheterization of the internal jugular vein in patients with chronic heart failure

BACKGROUND: The right internal jugular vein as a route for right heart catheterization and continuous infusion of drugs is increasingly used in patients with heart failure. Although this approach has several advantages, a small but definite number of unsuccessful vein punctures and/or of complications have been reported. This prospective study was designed to evaluate the usefulness of ultrasound techniques for cannulating internal jugular vein in a series of 310 consecutive patients with chronic heart failure. METHODS: In all patients a duplex scanning of internal jugular veins was performed before the cannulation. A subgroup of 62 patients was selected for having a "difficult" cannulation according to the following criteria: previous failure of cannulating the vein (3 unsuccessful needle advances); neck abnormalities; severe emphysema and respiratory insufficiency. In these patients a Doppler-guidance system, which consisted of a miniature ultrasound Doppler transducer inserted in a standard 19 gauge needle, was used. The needle was advanced under the skin following the maximal audio signal of the venous flow. The following variables were considered: success rate, number of needle advances to cannulate the vein, time elapsed from local anesthesia and the insertion of the catheter, minor and major complications. RESULTS: Duplex scanning showed that in 14 patients (4.5%) the right internal jugular vein was occluded or severely narrowed. In all patients the left internal jugular vein, which showed a compensatory dilatation, was successfully cannulated. In 294 of the remaining 296 patients the position of the vein was anterior to the carotid artery at a depth of 4-27 mm below the skin. With respect of the triangle formed by the two heads of the sternocleidomastoid muscle, the vein was central in 35%, medial in 15% and lateral in 60% of cases. Based on duplex scanning ultrasound data, 285 patients underwent internal jugular vein cannulation, which was achieved at the first attempt in 74% and within 3 attempts in 87% of cases. Minor and major complications occurred in 4 (1.4%) and in 1 (0.3%) respectively. By the Doppler guidance system, the cannulation was successfully achieved in 79% of patients at the first attempt and in 98% of patients (61/62) within 3 attempts. In one patient an uneventful puncture of the carotid artery occurred. The time to perform the cannulation was not significantly different using the two approaches (conventional approach: 4.4 +/- 3 minutes; Doppler guidance system: 4.2 +/- 2). Overall the internal jugular vein was successfully cannulated in 307/310 patients (99%). CONCLUSIONS: Ultrasound techniques provide useful information which facilitates the cannulation of the internal jugular vein in patients with heart failure. The Doppler guidance method allows a rapid and safe cannulation of the vein even in cases that are difficult using the conventional approach.     

Ultrasound-guided cannulation versus the landmark-guided technique for acute haemodialysis access

BACKGROUND: The correct placement of large-bore venous catheters plays an important role in the management of haemodialysis patients. Whilst the procedure for landmark-based placement of these catheters is well known, the technique is not without significant morbidity and mortality. Complications include arterial puncture, haematoma, and pneumothorax. The procedure may be further complicated in these patients by venous thrombosis and abnormal vein position from multiple previous attempts at venous access. METHODS: Data on the use of ultrasound guidance versus anatomical landmarks for the placement of internal jugular vein (n = 69) and femoral vein (n = 30) dialysis access was retrospectively analysed over a 13-month period. Data collected included age, sex, duration on dialysis, number of vein cannulation sets required, number of attempts for successful cannulation, salvage of failed cannulation using landmark-based technique by ultrasound guidance, and the complication rate. RESULTS: Internal jugular vein cannulation using ultrasound was ultimately successful in 96.7% compared to 82% in the landmark group. The vein was entered on the first attempt in 83.3% of patients with ultrasound compared to 35.9% of the landmark group (P < 0.0001). Seven patients in whom the landmark technique was unsuccessful had access placed under ultrasound guidance. There were fewer carotid artery punctures in the ultrasound group (7.7 versus 0%, P = n.s.). In the femoral vein group, the vein was entered on the first attempt in 85.7% of patients with ultrasound compared to 56.25% of the landmark group (P = n.s.). CONCLUSIONS: The use of ultrasound guidance is associated with fewer complications and is more likely to lead to cannulation of the vein at the first attempt in haemodialysis patients.     

A new way of access into the internal jugular vein

This paper describes a new technique for the canulation of the internal jugular vein. A transsection of the neck at the level of C4 (upper border of the thyroid cartilage) (Figure 1) shows the relative position of the internal jugular vein, the carotid artery and the sternocleidomastoid muscle. The internal jugular vein at this level is more superficial than is usually imagined. A cutaneous point of entry placed at the level of the thyroid cartilage on the medial border of the sternocleidomastoid muscle would be directly above, at the zenith of the carotid artery. From that point, moving a needle externally hugging the posterior aspect of the muscle will make it possible to reach the vein while actually moving away from the carotid artery.     

Initial experience in vascular plastic surgery in the surgical treatment of metastases of laryngopharyngeal cancer

The paper concerns conduction of the internal carotid artery and internal jugular vein reconstruction in 3 and 2 patients, respectively, operated for metastases of laryngopharyngeal carcinoma. 4 patients are still alive, 1 died on postoperative day 6. Bilateral one-stage Crile operation with application of autograft venous reconstruction of the internal jugular vein is detailed. Further research in this field is necessary.     

Thrombotic, infectious, and procedural complications of the jugular bulb catheter in the intensive care unit

OBJECTIVE: An assessment of the thrombotic, infectious, and technical complications of continuous jugular bulb catheter monitoring in the intensive care unit (ICU) was made. METHODS: Over a 1-year period, 44 patients suffering from traumatic brain injury, subarachnoid hemorrhage, or stroke received jugular bulb catheter monitoring in the ICU. They were followed for catheter insertion complications and the development of bacteremia. In 20 patients chosen randomly, an ultrasonographic evaluation was performed after removal of the catheter for an assessment of internal jugular vein thrombosis. RESULTS: Of the 44 patients, 1 became bacteremic; the source was identified as a thoracostomy site. Among the complications related to the 44 catheter insertions, there were 2 instances of carotid artery puncture (4.5%), 1 misplaced catheter (thoracic placement), and 1 clinically insignificant hematoma. Of the 20 patients investigated with ultrasonography, 8 (40%) had nonobstructive, subclinical internal jugular vein thrombi after jugular bulb catheter monitoring (95% confidence interval, 19-61%). The median monitoring duration was 3 days (range, 1-6 d). No clinical factor was identified to be associated with thrombus formation. CONCLUSION: We conclude the following: 1) the risk of bacteremia related to the jugular bulb catheter was negligible; 2) complications related to catheter insertion were rare and clinically insignificant; and 3) the incidence of subclinical internal jugular vein thrombosis after jugular bulb catheter monitoring is considerable. Although it is worthy to note this complication, no patient with a thrombus became symptomatic in the present series. The risk-benefit assessment of this monitoring technique must include consideration of subclinical thrombosis.     

Mycotic aneurysm of the innominate artery with supravalvular aortic stenosis

A case of mycotic innominate artery aneurysm in association with supravalvular aortic stenosis has been presented with successful resection as the first such case documented. Blood flow was restored with low cervical autogenous internal jugular vein, as an end-to-side vein graft from the left common carotid and end-to-end to the right subclavian and right common carotid arteries. The future repair of the supravalvular aortic stenosis could then be more easily accomplished.     

Complications of internal jugular vein catheterization

Percutaneous cannulation of the internal jugular vein has become a widely accepted method for monitoring central venous pressure, hyperalimentation, and rapid fluid administration. Although complications from this procedure have been rare, many unusual case reports are found in the literature. Three cases of otolaryngologic importance are presented. A revised technique of the internal jugular vein catheterization is described.     

Percutaneous femoro-porto-jugular venovenous shunt in orthotopic liver transplantation

Veno-venous bypass (VVB) by the percutaneous introduction of cannulas in the right internal jugular vein during liver transplantation may reduce the complications derived from the classical method of axillary vein dissection. The results and complications observed over a two and a half year period in 126 consecutive patients submitted to liver transplantation in whom preparation for femoral-portal-jugular veno-venous bypass was carried out are reported. Twelve complications (9.5%) were observed in the 126 patients. All the complications were due to jugular cannulation and were divided as follows: in 7 patients (5.5%) some of the guide introductions were unsuccessful following multiple punctures; in 2 patients (1.6%) the right carotid artery was punctured; 2 hemothorax (1.6%) were observed and one pneumothorax (0.8%). Forty patients required veno-venous bypass. The blood flows obtained during VVB were suffice in all the cases with a mean +/- standard deviation of 2.21 +/- 0.44 l/min-1. The technique of femoral-portal-jugular veno-venous bypass is a good alternative to the classical method of the axillary approach. It has advantages such as in the speed of installation of VVB and the utility of the large jugular vein during the remainder of the surgery for rapid fluid transfusions. Although the number of complications is low, they may be important thereby hindering intra management and post operative of the patients.     

Cannulation of neonates for venovenous extracorporeal life support

Venovenous access via a double-lumen cannula in the right internal jugular vein is the extracorporeal life support mode of choice for neonates with respiratory failure. We report a simplified method of cannulation. The advantages of this "semi-Seldinger" method include the ability to cannulate without ligating the internal jugular vein, and to adjust the position of the cannula and decannulate without re-exploring the wound.     

Accurate detection of anomalies by routine ultrasonography in an indigent clinic population

BACKGROUND: The jugular vein should be preferred to the subclavian vein for the placement of dialysis catheters, since subclavian catheters result in a high incidence (up to 50%) of subclavian vein thromboses and stenoses. METHOD: We conducted a prospective, randomized study between July 1996 and March 1997 to find out whether through the use of ultrasound, the rate of unsuccessful attempts in puncturing the internal jugular vein could be reduced. Seventy-three internal jugular vein cannulations were performed on 65 patients, using the guide-wire technique (according to Seldinger). Two groups were formed randomly by lot: in the first group the position of the internal jugular vein was marked on the skin by the use of ultrasound (Picker CS9100, Convex 3.5 MHz) before disinfection and local anaesthesia took place. The puncture was performed according to this mark. In the second group, the internal jugular vein was cannulated with real-time ultrasound guidance on the monitor. Any withdrawal of the needle with a consecutive forward movement was judged as an unsuccessful attempt, whether or not a second skin puncture was performed. RESULT: Thirty-seven punctures of the internal jugular vein with a skin mark determined by ultrasound yielded 87 unsuccessful attempts. Thirty-six punctures with real-time ultrasound guidance resulted in 10 unsuccessful attempts (P<0.01). The time from the beginning of the local anaesthesia to successful puncture was 4.8+/-2.2 min in the first group compared to 3.4+/-0.9 min in the second group (P<0.01). The cross-section of the internal jugular vein in the first group was 1.7+/-0.8 cm2 versus 1.5+/-0.8 cm2 in the second group (not significant). Neither of the two methods caused any complications. CONCLUSION: The puncture of the internal jugular vein with real-time ultrasound guidance resulted in significantly fewer unsuccessful attempts of venepuncture without requiring additional time.     

Complicated right subclavian artery pseudoaneurysm after central venipuncture

Life-threatening complications of central venipuncture are rare. We report an unusual case of a patient in whom a large right subclavian pseudoaneurysm developed, causing pressure necrosis of the membranous trachea and esophagus, after right internal jugular vein cannulation. The patient underwent oversewing of the proximal and distal ends of the subclavian artery and primary tracheal repair. An esophageal leak that presented on the sixth postoperative day was treated by primary suture repair with proximal and distal diversion.     

Dumbbell type jugular foramen meningioma extending both into the posterior cranial fossa and into the parapharyngeal space: report of 2 cases with vascular reconstruction

Two cases with huge dumbbell type jugular foramen meningioma with extension into the parapharyngeal space are reported. A well co-ordinated surgical strategy for total resection to this high risk tumour with neurosurgeons, otolaryngologists and plastic surgeons is mandatory to minimise operative complications. Both of our patients presented with a cervical mass and lower cranial nerve palsies, and had huge dumbbell type masses extending from the posterior cranial fossa through the jugular foramen to the parapharyngeal space, encasing the cervical internal carotid artery. Gross total resection of the tumours was successfully achieved by basically a 2-stage operation. In the first stage, posterior fossa tumours were removed by the transjugular approach, combined with the petrosal approach in one case. In the second stage, cervical tumours were removed along with the cervical carotid artery by the transcervical and/or transmandibular approach, followed by vascular reconstruction from the ipsilateral carotid artery to the middle cerebral artery using saphenous vein graft. From these experiences, we recommend this 2-stage operation for large dumbbell type meningiomas extending to the infratemporal/parapharyngeal space. The intracranial tumour is removed at the first operation. The extracranial portion is resected at the second, and if necessary, the involved cervical carotid artery is resected and simultaneous revascularisation using saphenous vein graft is performed with a vascularised free muscle graft. This strategy could maximise the functional preservation on the one hand, and minimise the surgical risk, such as postoperative infection, on the other.     

The incidence of artery puncture with central venous cannulation using a modified technique for detection and prevention of arterial cannulation

BACKGROUND: Cannulation of the central circulation is essential for management of patients who require major surgery, and for patients who are critically ill. Arterial puncture is the most frequent complication associated with central venous cannulation, and is potentially fatal. Detection of arterial puncture can be problematic, especially in patients with cyanotic congenital heart disease. METHODS: One thousand eleven consecutive cardiothoracic and vascular surgical patients who required central venous cannulation were studied using a new technique for detection of arterial puncture and prevention of arterial cannulation. This technique involves continuous pressure transduction of the steel introducer needle. Central venous cannulation was attempted in all patients. The sites of attempted catheterizations, number of arterial punctures and cannulations, and the number of successful catheterizations were noted. All patients were treated in accordance with standard anesthetic and surgical techniques in the institution. RESULTS: One thousand one hundred seventy-two central venous catheters were placed. The overall success rate was 99.6%. The incidence of arterial puncture was 9.3% for central venous cannulation attempts of the internal jugular, subclavian, and femoral veins. No arterial cannulation occurred, and none of the patients had significant complications. Congenital heart disease patients had a higher incidence of arterial puncture (14.1%) and a lower rate (96.8%) of successful cannulation. CONCLUSION: Pressure transduction of the steel needle is a useful technique for detecting arterial puncture and preventing arterial cannulation during attempts to achieve central venous cannulation.     

Orbital venous approach to the cavernous sinus: an analysis of the facial and orbital venous system

Carotid-cavernous fistulas are abnormal communications between the internal carotid artery and the cavernous sinus produced by a rupture of the wall of the carotid artery or one of its branches into the sinus. Extradural branches of the internal or external carotid arteries may communicate with the cavernous sinus, producing proptosis, progressive glaucoma, and ocular vascular engorgement. Various approaches to obliterate these fistulas have evolved, many of which carry high morbidity or are precluded by anatomical considerations. Analysis of the venous anatomy of the orbit and face, including human cadaver dissections, reveals a new and safe approach to the cavernous sinus, requiring microsurgical isolation and cannulation of the superior ophthalmic vein through an anterior orbital approach. Selective embolization of a carotid-cavernous fistula can be performed successfully through this route. We present pertinent anatomy and technical considerations and the successful clinical application of these principles. Surgeons familiar with craniofacial anatomy and microvascular techniques can apply these principles and play an active role in the treatment of these complex problems.     

Colchicine-induced myoneuropathy in childhood

Carotid-jugular arteriovenous fistulas (AVF) are extremely rare with only 20 cases reported in the literature up to December 1996. The case of a 74-year-old man (the oldest reported in the literature) with abnormal communications between the external carotid artery and the internal jugular vein is reported. The condition was treated by platinum coil embolization via catheterization and by repeated operations to ligate the branches of the external carotid artery, besides removal of the tissue containing the fistula and ligation of the external carotid at its origin. The result was incomplete because about 6 months after the last operation the patient showed the same symptoms, although in a milder form. Until standard treatment is established, the appropriate technique should be decided on a patient-to-patient basis.     

A model for the extended studies of hepatic hemodynamics and metabolism in swine

To our knowledge postoperative hepatic hemodynamics and hepatic metabolism have not been fully studied on a long-term basis. Our goal was to develop a large animal model that would permit the measurement of hepatic blood flow (BF), perihepatic pressures (P), and hepatic metabolism in a long-term setting. Catheters were inserted into the jugular vein, carotid artery, pulmonary artery, hepatic vein, and portal vein (PV) of 27 commercially bred pigs; ultrasonic transit time flowmeter probes were placed around the hepatic artery and PV. Daily postoperative measurements of jugular vein P, carotid artery P, pulmonary artery P, hepatic vein P, and PVP, as well as hepatic artery BF and PVBF, were recorded for 20 days. Hepatic carbohydrate metabolism was assessed by arteriovenous difference techniques. Jugular vein P, pulmonary artery P, hepatic vein P, PVP, and heart rate reached steady-state values during the first week, with a mean +/- SEM of 1.0 +/- 0.3 mm Hg for jugular vein P, 21.4 +/- 2.1 mm Hg for pulmonary artery P, 4.3 +/- 0.4 mm Hg for HVP, 7.8 +/- 0.5 mm Hg for PVP, and 116 +/- 4 beats per minute for heart rate. Mean carotid artery P increased from 65 +/- 3 mm Hg during surgery to 94 +/- 2 mm Hg on postoperative day 1 (P < 0.001) and to a mean 101 +/- 2 mm Hg thereafter. Total hepatic BF reached a steady-state value of 1,132 +/- 187 ml/min by postoperative day 7 (P = 0.19). Over week 1 hepatic artery BF measured as a percentage of total hepatic BF decreased from 35.0 +/- 3.0% to 15.5 +/- 2.7%, and PVBF increased from 65.0 +/- 3.0% to 84.5 +/- 2.7% (P < 0.005); both variables were steady thereafter. In the hemodynamic steady state the net hepatic balances of glucose, lactate, glycerol, and alanine in 5 pigs were 9.9 +/- 4.0, -4.2 +/- 0.4, -2.3 +/- 1.1, and -0.68 +/- 0.22 micromol/kg per min respectively. The net gut (portal-drained viscera) balances of glucose, lactate, alanine, and glycerol were -2.0 +/- 2.5, 1.1 +/- 0.5, 0.73 +/- 0.18, and -0.69 +/- 0.19 micromol/kg per min respectively. Thus, a reliable large animal model was developed to study acute and chronic hepatic hemodynamics and metabolism.     

Surgical anatomy of the infratemporal fossa: the styloid diaphragm revisited

INTRODUCTION: The infratemporal fossa (ITF) gives passage to most major cerebral vessels and cranial nerves. Dissection of the ITF is essential in many of the lateral cranial base approaches and in exposure of the high cervical internal carotid artery (ICA). We reviewed the surgical anatomy of this region. METHODS: Direct foraminal measurements were made in seven dry skulls (14 sides), and the relationship of these foramina to each other and various landmarks were determined. Ten ITF dissections were performed using a preauricular subtemporal-infratemporal approach. Preliminary dissections of the extracranial great vessels and structures larger than 1 cm were performed using standard macroscopic surgical techniques. Dissection of all structures less than 1 cm was conducted using microsurgical techniques and instruments, including the operating microscope. The anatomic relationships of the muscles, nerves, arteries, and veins were carefully recorded, with special emphasis regarding the relationship of these structures to the styloid diaphragm. The dissection was purely extradural. RESULTS: The styloid diaphragm was identified in all specimens. It divides the ITF into the prestyloid region and the retrostyloid region. The prestyloid region contains the parotid gland and associated structures, including the facial nerve and external carotid artery. The retrostyloid region contains major vascular structures (ICA, internal jugular vein) and the initial exocranial portion of the lower Cranial Nerves IX through XII. Landmarks were identified for the different cranial nerves. The bifurcation of the main trunk of the facial nerve was an average of 21 mm medial to the cartilaginous pointer and an average of 31 mm medial to the tragus of the ear. The glossopharyngeal nerve was found posterior and lateral to stylopharyngeus muscle in nine cases and medial in only one. The vagus nerve was consistently found in the angle formed posteriorly by the ICA and the internal jugular vein. The spinal accessory nerve crossed anterior to the internal jugular vein in five cases and posterior in another five cases. It could be located as it entered the medial surface of the sternocleidomastoid muscle 28 mm (mean) below the mastoid tip. The hypoglossal nerve was most consistently identified as it crossed under the sternocleidomastoid branch of the occipital artery 25 mm posterior to the angle of the mandible and 52 mm anterior and inferior to the mastoid tip. CONCLUSION: The styloid diaphragm divides the ITF into prestyloid and retrostyloid regions and covers the high cervical ICA. Using landmarks for the exocranial portion of the lower cranial nerves is useful it identifying them and avoiding injury during approaches to the high cervical ICA, the upper cervical spine, and the ITF.     

Long-term patency of vein grafts preserved in liquid nitrogen in dimethyl sulfoxide

Autogenous canine jugular veins were stored in 15% dimethyl sulfoxide (DMSO) in liquid nitrogen vapor for one to 28 days and then implanted in the carotid artery as autografts. The patency rate at one year was 62.5-87.5%. The patency rate of fresh jugular vein autografts placed in the carotid artery for one year was 75%. Similar autografts stored in liquid nitrogen vapor for one to 28 days without the cryopreservative DMSO exhibited a zero to 12.5% patency rate at one year. Scanning electron microscope studies revealed preservation of theendothelium in DMSO protected veins and a damaged or sloughed endothelium in veins frozen without DMSO cryopreservation.     

Totally implantable systems in oncology: the cephalic vein as an elective access port

The use of totally implantable systems (TIS) has noticeably reduced risks and enhanced quality of life for cancer patients undergoing long-term chemotherapy. One aspect remains open to discussion: site of venous access and placement procedure. Opinions are divided between two techniques: percutaneous access by direct puncture of the subclavian vein or surgical access through the veins afferent to the subclavian: the cephalic, the jugular, or other minor veins. We report our experience with 63 patients undergoing surgical placement of TIS through the cephalic vein. The operatory procedure is divided into four phases: 1) Preparation of vein and cannulation; 2) X-ray control; 3) creation of subcutaneous sheath; 4) reconstruction. None of the 63 patients developed immediate complications. 46 patients are currently using TIS for a period ranging from 17 to 1862 days. 16 patients died during the time their TIS was in place. In only one patient was the TIS removed after treatment was completed. From our results it is clear that the surgical access through the cephalic vein is the most reliable method of TIS placement, with fewer risks concerning immediate and post operatory complications.     

Insidious rupture of the Achilles tendon after ciprofloxacin-induced tendopathy. A case report

A 64-year-old male patient had two episodes of transient ischemic attack and a cerebral infarction. Cerebral angiography showed 50% stenosis at the junction of left internal carotid artery and 90% stenosis at left mid-cerebral artery (MCA). Coronary angiography showed two vessel disease with arteriosclerotic change and underwent coronary artery bypass grafting. To prevent intraoperative cerebral infarction, we used brain protect solution just before starting ECC, set perfusion flow around 3 l/min/m2, monitored the flow of left MCA using Transcranial Doppler (TCD) and the saturation of left internal jugular vein (SjO2) continuously. PaCO2 was controlled around 45 mmHg. TCD showed good pulsatile flow, and SjO2 was kept over 60%. The patient recovered consciousness 2 hours after operation in the intensive care unit without paresthesia. We thought the number of open-heart cases with cerebrovascular disease increased, and pulsatile low of ECC by intraaortic balloon pumping and the monitoring of SjO2 are useful for the cases.
