BACKGROUND: We analyzed 76 patients with cervical vascular injuries from penetrating neck trauma (n = 528) between 1977 and 1990 at a level I trauma center to evaluate the role of angiography in diagnosis and management and to assess the course and outcome of these patients. METHODS: Patients who were hemodynamically unstable underwent immediate surgical exploration. Stable patients were subjected to diagnostic investigation. Angiography was routinely performed to diagnose vascular injury in zones I and III and zone II if the trajectory was in the vicinity of major vessels. Therapeutic embolization was performed when possible at angiography; all other vascular injuries were treated surgically. RESULTS: Thirteen patients (2.5%) died of penetrating neck trauma, in 12 of whom hemorrhage was the contributing factor (12/76; 15.8% of patients with vascular injury). In nine patients who were hemodynamically stable vascular injury was diagnosed by angiography: 5 (6.8%) of 73 in zone I and 3 (5.4%) of 56 in zone III, four of whom underwent therapeutic embolic occlusion of the injured vessel. Injuries to vertebral and subclavian arteries and subclavian and innominate veins were often multiple, causing exsanguination and death (6.8% in zone I). In three patients with no preoperative neurologic deficit, the internal carotid artery was ligated without complication; in all other patients injury to the common carotid or internal carotid artery was repaired, in six of them with polytetrafluoroethylene grafts. CONCLUSIONS: Selective management of penetrating neck trauma should include routine angiography in zones I and III. Injuries to the common and internal carotid arteries should be repaired. The internal carotid artery may be ligated in the absence of preoperative neurologic deficit. Arterial injuries in the neck can be repaired with polytetrafluoroethylene grafts. 相似文献

Of the 77 cases of renal trauma treated at Oulu University Central Hospital during the years 1965--1975, 60 injuries were minor and 17 severe. 73 of these injuries were closed and 4 penetrating. The rate of operative treatment in severe renal injuries was 88% minor renal injuries being treated conservatively. Primary exploration was done in 18 of the 77 cases and in all patients with penetrating injuries. Only 7 of the 73 patients with blunt trauma and one of the 4 patients with penetrating injury required nephrectomy, including one patient with renal carcinoma. 6 of the 77 patients died, most as a result of severe associated injuries, giving a mortality of 8%. None of the surviving patients treated for renal trauma suffered from major complications. In 13 of the 18 patients operated upon, renal injury was the main indication for operation. Operation was performed in 5 of the 18 patients after immediate radiological evaluation. The advantages of immediate surgical management in severe renal injuries are early and final treatment, short hospital stay, and low incidence of complications. Qualifications for emergency surgery are access to renal angiography and familiarity with reparative renal procedures. 相似文献

Few guidelines are available with which to facilitate treatment in patients with noniatrogenic injuries of the esophagus. Early diagnosis and proper management are essential if a good outcome is to be expected. In an effort to define better the treatment of patients with penetrating and blunt injuries of the esophagus, we report our recent 5-year experience at an urban trauma center. From July 1988 to June 1993, nineteen patients with esophageal perforations from penetrating (18) and blunt (1) trauma were identified by our trauma registry. There was no mortality in this group of patients and morbidity was mostly due to associated injuries. Eleven cervical esophageal injuries were repaired. One cervical injury was treated by stopping oral intake and giving intravenous antibiotics. The neck was not drained in 10 of the surgical cases. In 1 patient a tracheoesophageal fistula developed, which later was repaired with a pectoralis muscle flap. Seven perforations were identified in the thoracic (2) and abdominal (5) portions of the esophagus. All were due to gunshot wounds. In 4 cases, a fundal wrap was used to reinforce the repairs. Postoperative contrast studies confirmed that all repairs were intact. We conclude that penetrating and blunt tears of the esophagus can be repaired safely with minimal mortality. Morbidity is usually from associated injuries such as to the spinal cord and trachea. When identified early, cervical esophageal injuries do not need to be drained routinely. 相似文献

Blunt trauma to the common iliac artery is a rare phenomenon. Although seat belt injuries to the abdominal aorta and the carotid artery have been reported, there is only one previous report in the literature of seat belt injury to the common iliac artery. We report a case of common iliac arterial injury directly related to use of the lap belt and not associated with pelvic or lumbar fractures. The literature related to blunt trauma of the common iliac artery is reviewed. 相似文献

Acute blunt laryngeal trauma can be a life-threatening event and often poses a difficult airway management problem. Patients may be unable to supply important anemnestic facts because of aphonia or intubation as a result of their injury. Therefore the immediate recognition and appropriate initial assessment and treatment are vital for a successful outcome. The first step is assuring an appropriate airway, either by careful intubation or temporary tracheotomy. An assessment of potential vascular and oesophageal injuries must be undertaken. The use of computerized tomography (CT) with contrast material is especially useful in identifying and localizing the damage caused by blunt neck injuries. Laryngeal fractures, air in the soft tissues and the extravasation of contrast material in the neck are all helpful in assessing the injuries before surgical intervention. Immediate initial surgery is aimed at stabilizing the cartilaginous framework and repairing the mucosa. We present a case of severe laryngeal injury caused by blunt trauma to the neck; our evaluation, treatment and the outcome. 相似文献

Acute mental status change in the first 24 hours after trauma is uncommon in nonhead injured patients who initially present with a normal sensorium. Although arterial hypoxemia is the classic etiology for such a mental status change, three less common etiologies should always be considered: cerebral fat embolism, blunt carotid artery injury, and vertebrobasilar artery thrombosis. Prompt diagnosis and appropriate treatment can significantly improve patient morbidity and mortality. Three nonhead injured trauma patients are described illustrating cerebral fat embolism, blunt carotid artery injury, and vertebrobasilar artery thrombosis as causes of acute mental status change. Each patient initially presented with a clear sensorium, but subsequently developed neurological deficits within 24 hours after admission. All had a normal admission CT scan of the head. MRI or conventional arteriography was diagnostic in each case. Any patient who is initially lucid and subsequently develops a neurological deficit, or a patient whose neurological status does not correlate with brain CT findings should undergo immediate evaluation for possible cerebral fat embolism or cervical vessel injury. An algorithm for management of nonhead injured trauma patients with acute mental status deterioration is presented. 相似文献

Despite several large studies, the scoop and run versus field stabilization debate in prehospital trauma care continues. It is unlikely that all trauma patients are best treated by either field stabilization or scoop and run and the most effective form of prehospital care may be dependent upon the type of injuries sustained. Studies suggest that penetrating trauma involving major vascular injury may be best treated by scoop and run since advanced life support (ALS) measures serve only to delay time to definitive surgical treatment. Conversely, patients with head injuries may benefit from rapid ALS performed on scene in order to control airway and breathing problems, and reduce intracranial pressure prior to transport. Between these two groups of patients lie those with blunt trauma in whom scoop and run may be most appropriate if there is major vascular damage or those in whom field stabilization may offer the patient a greater chance of survival if blood loss is not a life-threatening problem. 相似文献

Penetrating injuries to the thoracoabdominal region represent a complex and diverse population of injuries. The clinician managing such cases must be able to consider all potential injuries, rapidly recognize life-threatening sequelae, and precisely diagnose and quickly manage these patients. The diverse nature of some of the potential presentations of patients with penetrating thoracoabdominal trauma is discussed. The most recent advances and controversies involving the evaluation and management of patients with penetrating thoracoabdominal trauma are also discussed. 相似文献

Changes in the management of trauma over the past few years are significantly affecting postgraduate surgical education, with the lack of operative trauma experience being a major concern in some programs. This problem is accentuated in residency programs that obtain their trauma caseload primarily from blunt injury. Our experience over the past 6 years confirms that the growing trend toward nonoperative management of blunt liver and spleen injuries in adults is likely to exacerbate this problem. Blunt trauma admissions to our Level I trauma center increased from 2888 from 1991 through 1993 (group A) to 3587 from 1994 through 1996 (group B). Liver and/or splenic injuries occurred with equal frequency in both groups. Whereas diagnostic peritoneal lavage was used in 26 per cent of group A, its use dropped to 2 per cent in group B as abdominal computerized tomography was used more frequently to evaluate these patients. Nonoperative management increased from 10 per cent of group A to 54 per cent of group B. As a result, therapeutic laparotomies dropped from 85 in group A (58% of patients with liver/splenic injuries) to 74 (35%) in group B and nontherapeutic laparotomies from 48 (33%) to 23 (11%). While the evolution in the management of blunt liver and splenic injuries has resulted in the avoidance of nontherapeutic laparotomies, the operative caseload available to surgical housestaff has been adversely affected. Although the Residency Review Committee has stressed the importance of the critical care management of these patients, the criteria used to evaluate the number of trauma cases in postgraduate surgical education may need to be revised. 相似文献

Pancreatic injury from penetrating trauma continues to be a source of significant morbidity and mortality, with questions remaining regarding optimal treatment of injuries. Our goal was to evaluate current trends in the operative management of these injuries. Our patient population comprised all patients admitted to one of three Level I trauma centers over an 8-year period that had sustained penetrating pancreatic trauma. The study was a retrospective chart review. Sixty-two patients were identified. All had associated abdominal injuries, with the liver and stomach being the most commonly injured organs. There were 14 deaths (mortality 22.6%), 10 within the first 48 hours due to associated vascular injury. In the 52 patients surviving beyond 48 hours, there were 19 patients with injuries to the main pancreatic duct and 33 with parenchymal injuries only. Pancreatic resection was carried out for all patients with ductal injury except for one, who later required distal pancreatectomy for pseudocyst and pancreatic fistula. Significant pancreatic fistulae developed in five patients, three in patients treated by drainage and two in patients treated by resection. The incidence of fistula formation was significantly higher for drainage versus resection in the patients with ductal injuries. The incidences of other complications were not affected by type of pancreatic injury, associated injuries, or method of management. We conclude that the majority of deaths in patients with penetrating pancreatic trauma are due to associated organ or vascular injuries. Appropriate management of the pancreatic injury can reduce the long-term complications. These results support treating patients with suspected ductal injuries by appropriate resection. Drainage should probably be sufficient for most nonductal pancreatic injuries. 相似文献

STUDY DESIGN: Radiographs and charts of 61 patients sustaining cervical spine trauma were studied prospectively to determine the incidence of vertebral artery injuries and possible correlative factors. Statistical analysis was conducted using chi-square testing of a two-way classification system. OBJECTIVES: To elucidate the incidence of vertebral artery injuries associated with cervical spine trauma, and to determine the value of various factors in predicting the existence of a vertebral artery injury. SUMMARY OF BACKGROUND DATA: During a 7-month period, 61 patients (41 male patients, 20 female; average age, 40.3 years) with cervical spine trauma were studied. METHODS: All patients admitted to the authors' hospital with cervical spine injuries underwent magnetic resonance imaging and magnetic resonance angiography of their cervical spine. All magnetic resonance angiographies were examined for vertebral artery injury. Data on demographics and the injury were recorded. RESULTS: Complete disruption of blood flow through the vertebral artery was demonstrated by magnetic resonance angiography in 12 of the 61 patients (19.7%). Ten of the 12 patients (83%) had either flexion distraction or flexion compression injuries. Age, sex, mechanism of injury, neurologic impairment, and associated injuries were not statistically significant in predicting the presence of a vertebral vessel occlusion. CONCLUSION: The findings in this study may support the need for vertebral vessel evaluation in selective patients, particularly those with flexion injuries and with neurologic symptoms consistent with vertebral artery insufficiency syndrome that do not correlate with the presenting bone and soft-tissue injuries. 相似文献

OBJECTIVE: This study was conducted to evaluate those factors associated with popliteal artery injury that influence amputation, with emphasis placed on those that the surgeon can control. SUMMARY BACKGROUND DATA: Generally accepted factors impacting amputation after popliteal artery injury include blunt trauma, prolonged ischemic times, musculoskeletal injuries, and venous disruption. Amputation ultimately results from microvascular thrombosis and subsequent tissue necrosis, predisposed by the paucity of collaterals around the knee. METHODS: Patients with popliteal artery injuries over the 10-year period ending November 1995 were identified from the trauma registry. Preoperative (demographics, mechanism and severity of injury, vascular examination, ischemic times) and operative (methods of arterial repair, venous repair-ligation, anticoagulation-thrombolytic therapy, fasciotomy) variables were studied. Severity of extremity injury was quantitated by the Mangled Extremity Severity Score (MESS). Amputations were classified as primary (no attempt at vascular repair) or secondary (after vascular repair). After univariate analysis, logistic regression analysis was performed to identify the independent risk factors for limb loss. RESULTS: One hundred two patients were identified; 88 (86%) were males and 14 (14%) were females. Forty injuries resulted from blunt and 62 from penetrating trauma. There were 25 amputations (25%; 11 primary and 14 secondary). Patients with totally ischemic extremities (no palpable or Doppler pulse) more likely were to be amputated (31% vs. 13%; p < 0.04). All requiring primary amputations had severe soft tissue injury and three had posterior tibial nerve transection; the average MESS was 7.6. Logistic regression analysis identified independent factors associated with secondary amputation: blunt injury (p = 0.06), vein injury (p = 0.06), MESS (p = 0.0001), heparin-urokinase therapy (p = 0.05). There were no complications with either heparin or urokinase. CONCLUSIONS: Minimizing ischemia is an important factor in maximizing limb salvage. Severity of limb injury, as measured by the MESS, is highly predictive of amputation. Intraoperative use of systemic heparin or local urokinase or both was the only directly controllable factor associated with limb salvage. The authors recommend the use of these agents to maximize limb salvage in association with repair of popliteal artery injuries. 相似文献

Our objective was to determine the incidence, management, and outcome of traumatic pancreatic injury. A retrospective review was performed of all patients with pancreatic injury admitted to two Level I trauma hospitals over a 10-year period. Comparisons were made with Chi square or Fisher's exact tests. Of 16,188 trauma admissions, 72 patients (0.4%) had pancreatic injury. The mean age was 30 years, and 30 patients (69%) were male. Mechanism of injury was gunshot in 32 (45%), blunt in 27 (37%), and stab wound in 13 (18%). The pancreas was involved in 1.1 per cent of patients with penetrating injuries compared to 0.2 per cent with blunt injuries (P < 0.01). There were 18 grade I (25%), 32 grade II (45%), 16 grade III (22%), and 5 grade IV (7%) injuries. Initial diagnosis was made intraoperatively in 63 patients and by computed tomography in 8. The mean injury grade was significantly lower on computed tomography compared to surgical exploration (0.4 vs 2.0; P < 0.05). Operative procedures included distal pancreatectomy in 23 (32%), exploration only in 22 (31%), external drainage in 13 (18%), pancreatorrhaphy in 4, internal drainage in 2, and proximal resection in 2. Mortality was 16.6 per cent and was not related to the mechanism or grade of injury. Mean Injury Severity Score and transfusion requirements were significantly greater in patients who died (P < 0.05). Morbidity occurred in 30 patients (42%), including pancreatic fistula (11%), pancreatitis (7%), and pancreatic pseudocyst (3%). Six patients (8%) developed intra-abdominal abscesses, and all had associated liver or intestinal injuries. In patients with grade I and II injuries, morbidity was higher with external drainage compared to exploration without drainage. Pancreatic injury is infrequent and is more often associated with penetrating trauma. Diagnosis is most commonly made by exploration and cannot be excluded by computed tomography. Drainage of low-grade injuries may not be necessary. Morbidity and mortality in patients with pancreatic trauma is significant and is primarily due to associated injuries. 相似文献

STUDY DESIGN: A prospective study to determine the long-term outcome of traumatically induced vertebral artery injuries. Magnetic resonance angiography was performed at the time of cervical injury and at a follow-up office visit. OBJECTIVE: To determine the long-term outcome in terms of arterial flow competency of traumatically induced vertebral artery injuries. SUMMARY OF BACKGROUND DATA: Vertebral artery injury associated with cervical spine trauma has been well documented; however its healing or nonhealing potential has not been elucidated. METHODS: During the 7-month period from July 1993 to January 1994, all patients admitted to the authors' institution with cervical spine injuries underwent magnetic resonance imaging and magnetic resonance angiography of the cervical spine to determine the patency of their vertebral arteries. Magnetic resonance angiography was performed at the time of injury and at a follow-up office visit. Twelve of 61 patients were found to have a lack of signal flow within one of their vertebral vessels during this study period. RESULTS: Eighty-three percent of the patients (five of six) who were available for follow-up observation in this study did not manifest flow reconstitution of their vertebral arteries after an average 25.8-month follow-up period. CONCLUSIONS: According to these data, most patients with vertebral artery injuries after nonpenetrating cervical spine trauma do not reconstitute flow in the injured vertebral arteries. This lack of flow must be considered if future surgery in this region of the cervical spine is contemplated. 相似文献

Penetrating injuries of the eye are an important cause of unilateral visual loss. We studied a series of 82 cases of penetrating injuries treated here from 1987 through 1993. The injuries were caused by sharp objects in 66% and blunt trauma in 6%. The prognosis after a penetrating injury is greatly influenced by the nature of the injury and the extent of the initial drainage. Among factors associated with an unfavorable visual outcome were diminished preoperative visual acuity and scleral wounds with dense vitreous hemorrhage. 相似文献

Aneurysms constitute uncommon sequelae of injuries to the thoracic outlet. Most such aneurysms are secondary to blunt trauma and usually involve the great vessels at their take-off from the aortic arch. Penetrating injuries are more often identified in the more distal vessels and only very rarely present as pseudoaneurysms. Reported here is a single case of a chronic posttraumatic pseudoaneurysm arising from both the right common carotid artery and the right subclavian artery. The workup and surgical approach provide practical lessons, complemented with illustrations that aid in the understanding of the case. It is an unusual case because of the dual-inflow nature of the aneurysm. 相似文献

Blunt injury of the internal carotid artery (ICA) is a rare entity that should be considered by Maxillofacial surgeons in patients with facial fractures. Its recognition is often delayed because of the common association with other severe multi-system injuries. Early diagnosis is the key to successful management; the arteriography plays a confirmatory role on the diagnosis and determines whether surgical management of the injury is feasible. Therapeutic alternatives vary from one center to another; they include observation, conservative treatment, anticoagulation, ligation of the carotid artery with or without extracranial-intracranial bypass, and arterial reconstruction. 相似文献

Rupture of the thoracic aorta secondary to blunt chest trauma is an exceedingly uncommon injury in pediatric patients. We present a case of blunt traumatic aortic disruption in a 10-year-old child who was successfully managed by primary aortic repair using partial cardiopulmonary bypass. The epidemiology and pathophysiology of this injury, with particular reference to children, is reviewed. The ongoing controversies regarding the diagnosis and operative management of this injury are summarized. 相似文献

OBJECTIVE: This study attempts to document the incidence of unsuspected blunt carotid artery injury (BCI) in a prospective series of consecutive blunt trauma patients undergoing angiographic evaluation of the aorta. Previous studies have included mainly patients who became symptomatic from BCI, thus documenting a "detected incidence." METHODS: During a 22-month period, all patients undergoing angiographic evaluation of the aorta after blunt trauma who were not felt to be at increased risk for BCI were included in the screening protocol. All patients initially suspected of BCI were studied outside the protocol. Angiographic evaluation of the carotid arteries was performed using nonselective contrast injections after aortic injury had been ruled out. RESULTS: The incidence of BCI among those patients screened under the protocol (n = 119) was 2.5% (3 of 119). Among all patients undergoing aortic evaluation at presentation (n = 171), the detected incidence of BCI was 3.5% (6 of 171). The detected incidence of BCI among all patients during the study period was 0.32% (10 of 3174). No risk factors for BCI were identified beyond the severity of trauma that led to aortic evaluation. CONCLUSION: The incidence of BCI found in those patients screened in this study, nearly 10 times the incidence of BCI in our blunt trauma population overall, suggests that these patients represent a subgroup on which to focus screening efforts, regardless of the diagnostic tools employed. The similarity between the angiographic incidence and the detected incidence of BCI in this study argues that few BCIs remain asymptomatic. All blunt trauma patients injured sufficiently to prompt aortic evaluation at presentation should be screened in some manner for BCI. 相似文献
