OBJECTIVE AND IMPORTANCE: Although an autogenous saphenous vein is frequently used as a bypass graft, an aneurysm of a venous graft is a rare complication, especially in the case of cerebrovascular revascularization. We report a case of a successfully treated aneurysmal change in a venous graft after short vein bypass grafting. CLINICAL PRESENTATION: A 60-year-old man underwent a left subclavian-to-vertebral artery bypass operation with an interposed saphenous vein graft because of severe stenosis of the vertebral artery bilaterally. Angiograms of the left subclavian artery, obtained 4 months later, showed good patency of the graft without any dilation or stenosis. One year after the bypass surgery, the patient became aware of a pulsating mass in the left supraclavicular region, which was regarded as the grafted vein itself. A giant aneurysm of the vein graft, which developed at the nonanastomotic site, was shown in the angiogram 4 years later. INTERVENTION: The aneurysm was resected, and patch grafting of the orifice of the aneurysmal neck covered with an artificial vessel as a reinforcement was performed. CONCLUSION: The aneurysm seemed to have developed in a curved segment because of hemodynamic stress. 相似文献

Hepatic artery aneurysms are considered a rare event even though their report in the literature are becoming more and more frequent. A case of a 50-year-old man with common hepatic artery arterial aneurysm is reported. Initially, aspecific upper abdominal symptoms were found, but the great improvement in the diagnosis of vascular disease allows us to recognize this pathology which has a high risk of rupture so that an aggressive treatment is required. 相似文献

Secondary involvement of the genitourinary tract with malignant melanoma is a common autopsy finding, but rarely evident clinically. We report a rare case involving a previously asymptomatic patient presenting with gross hematuria and a large renal mass, which was found to be metastatic melanoma. We propose that metastatic melanoma to the kidney, although rare, be considered in the differential diagnosis of disease processes causing hematuria. 相似文献

The authors report the case of a suicide pact of two men (22 and 24 years old), which exhibits extraordinary circumstances concerning the personal profile and the suicide procedures. Both had a psychiatric history and were found dead near their severely damaged car, with gaggs in their mouth and a rope tightened around the neck and fixed to the car. Extra gas cans had also been placed in the car. Autopsy confirmed death due to severe trauma and rope strangulation. Toxicological analysis of the blood revealed codeine, dihydrocodeine, paracetamol in high, doxepine in lethal concentrations. According to police investigations, which has been confirmed by medical examination, both men had made arrangements for their suicide selecting a range of methods to kill themselves. 相似文献

To the best of our knowledge, this is the first report of external ear canal schwannoma in the English literature. Several detailed clinical and pathological features were demonstrated. We suggest that if a tender, encapsulated mass is found in the external ear canal, the diagnosis of schwannoma should be taken into consideration. 相似文献

The use of the Systematised Nomenclature of Pathology as the basis of an indexing system to histopathological data is outlined. Two computer programs which perform the task of producing codes from free English summaries are compared. It is concluded that a simple system has a great deal to offer the pathologist who is prepared to accept a set of constraints. 相似文献

We report the case of a newborn with a large left-sided congenital diaphragmatic hernia (CDH) who required extra corporeal membrane oxygenation (ECMO) for severe respiratory insufficiency. CDH repair had to be performed on bypass circulation. Intraoperatively, an atypical hemihepatectomy of the herniated lobe was conducted, because reposition of the liver led to a kinking of the vena cava and to a torsion of the right lobe, resulting in ischemia and compromised venous flow. The extraordinary anatomical indication and the potential danger of uncontrollable bleeding are discussed. 相似文献

The use of EMLA eutectic cream is very effective and well tolerated in superficial anaesthesia. It is particularly indicated in surgical treatment of inguinal hernia by local anaesthesia, to achieve the analgesia of superficial layers. This allows to reduce the total dose of anaesthetics administrated by infiltration, reducing the risk of overdose, eliminating the pain due to injection, and is very agreeable for the patients. 相似文献

Electrocardiographic abnormalities had been reported, in patients with subarachnoid hemorrhage, with variable percentage from 2% to 91%, according to several studies. The most common changes are T wave inversion, ST segment elevation or depression, QT prolongation, U waves, atrial flutter and fibrillation, ventricular fibrillation, supraventricular tachycardia, premature atrial and ventricular contractions. These findings occur within the first forty-eight hours after the onset of the symptoms; they usually are benign and transient. In a small percentage of cases generally in severe ESA, the ECG changes are associated with ventricular asynergy, coronary vasospasm or subendocardic necrosis. The arrhythmias could be produced either by autonomic discharges to the heart, during increased sympathetic activity due to ESA, or by a damage of cerebral areas with arrhythmogenic capacity. The importance of ECG abnormalities towards mortality and morbidity in patients with ESA has not yet been cleared; however, a careful monitoring is recommended to prevent severe cardiac complications and to obtain an indirect, further evaluation of the neurologic pathology. 相似文献

We report a case of gastroduodenal arterial aneurysm incidentally discovered by abdominal ultrasonogram, in which three-dimensional computed tomography (3D-CT) was useful for diagnosis. An 85-year-old man was hospitalized because of fever and liver dysfunction. Carcinoma of the papilla of Vater was diagnosed by endoscopic retrograde cholangio-pancreatography, while abdominal ultrasonogram and CT scan revealed a round mass measuring 6.2x4.1 cm on the ventral side of the pancreatic head. Three-dimensional CT demonstrated that the mass arose from a branch of the common hepatic artery and projected downward, indicating a gastroduodenal arterial aneurysm. During pancreatoduodenectomy and aneurysmectomy, it was confirmed that this aneurysm arose from the gastroduodenal artery. 相似文献

The authors evaluate in the submitted paper the results of surgical treatment of embolization into the bifurcation of the abdominal artery at the Second Surgical Clinic in Brno during 1990-1996. A total of 5 patients was involved whereby in all a cardiac cause of the embolization was obvious. The authors deal also with the time which has elapsed between the development of complaints and surgery, the type of anaesthesia, average length of operation. The operation is implemented concurrently by two teams as antero- and retrograde simultaneous bi-transfemoral embolectomy. The authors emphasize the importance of the metabolic condition of the patient as well as cardiac and renal functions before, during and after surgery. They consider the application of peroperative haemodialysis essential. During the postoperative period it is important to find the objective cause of the cardiac deficiency and treat it. Their results--a 40% mortality are comparable with those of other specialized departments. By comparison with a similar group treated at the same department twenty years previously the authors find a decline in the incidence of this disease and explain this phenomenon by an increased number of cardiosurgical operations in this area. 相似文献

We present what we believe is the first case in the literature of carcinoma of the lung presenting de novo as an intracardiac mass with bilateral, simultaneous popliteal artery embolization. Arterial thromboembolism of cardiac origin and in situ thrombosis of a preexisting atherosclerotic lesion or aneurysm account for the majority of cases of acute lower extremity ischemia. Less common causes include trauma, aortic dissection, venous ischemia, and foreign body or tissue embolization. Although the history, physical examination, and electrocardiographic findings may provide a likely explanation in many cases, noninvasive studies such as echocardiography may help further elucidate the embolic source. 相似文献

Primary PTCA as a means of reestablishing coronary blood flow in the infarct related artery is preferable in certain subgroups of patients with acute myocardial infarction. While the success rate of primary PTCA is very high, the procedure is not without risk. We report a case of hemodynamic collapse during PTCA due to an Amplatz guide catheter-induced, acute, and reversible aortic insufficiency. With the increasing use of the left Amplatz catheter for better guide support during PTCA, this unusual and previously unreported complication should be borne in mind. 相似文献
