The injuries of the femoral arteries were mistreated in 5 cases. The causes of the mistakes were resulted from: the initial cause of the injury was not carefully analyzed; the arterial injury was overlooked by the concomitant injuries, and the improper method of management was selected, as a result, 2 patients died from acute renal failure and the other 3 patients developed the complications of secondary thrombosis of the artery or rupture of the artery at the anastomotic site following repair. Of the 3 patients, 2 patients had recovered following reoperation and the other 1 patient had lost his limb from amputation. It should be emphasized that all of the following key points might avoid the mistakes occurred in the management of the injury of the femoral artery: (1) early diagnosis; (2) debredment of arteral end; (3) in infections wounds, insted of vein transplantation bypass technique should be done.
OBJECTIVE: To investigate the relationship between the different defect length of vessels and the options of vascular repair, and to compare the different options of repair because of the longitudinal biomechanical effect. METHODS: A clinical analysis was undertaken to evaluate the major arterial and venous injuries in human extremities repaired by end-to-end anastomoses or venous autograft(177 cases, 185 vessels). Compared the defect length of the same kind of vessels repaired by different options (Student-t test). Evaluated the defect length to repair arterial injuries between by end-to-end anastomoses and by vein graft by means of 95% confidence interval. RESULTS: There was significant difference between the defect length of brachial artery repaired by end-to-end anastomosis and femoral artery and popliteal artery repaired by autogenous vein graft (P lt; 0.01). The upper limit of confidence interval in the defect length of brachial artery, femoral artery and popliteal artery was 3.17 cm, 2.81 cm and 2.44 cm respectively by end-to-end anastomosis by means of 95% confidence interval. The lower limit of confidence interval in the defect length of brachial artery, femoral artery and popliteal artery was 2.82 cm, 2.41 cm and 2.17 cm respectively by vein graft by means of 95% confidence interval. The defect length of brachial artery, femoral artery and popliteal artery repaired by vein graft was linear correlation with the length of graft. CONCLUSION: Because of the longitudinal biomechanical difference of arteries and veins in human extremities, different options of repair are necessary to different arterial injuries.
ObjectiveTo summarize the mid-term follow-up results and postoperative aortic remodeling of treating blunt aortic injuries (BAI) with thoracic endovascular aortic repair (TEVAR).MethodsA retrospective study was conducted on BAI patients treated with TEVAR, who were admitted into the Department of Vascular Surgery in Zhongshan Hospital, Affiliated to Fudan University between September 2003 and December 2015. There were 15 males and 9 females at an average age of 45.6±14.0 years. The mechanism of BAI was mainly auto car crash. Totally 25 entry tears were detected and most of them were located at the aortic isthmus.ResultsTwenty-four BAI patients survived and eventually went through TEVAR. One patient died of pulmonary embolism 1 week post-TEVAR. Rate of technical success, clinical success and perioperative mortality was 100.0%, 95.8%, and 4.2%, respectively. Nineteen patients were followed up with a mean time of 35.1(13-87) months. All of them survived this period. Based on the follow-up imaging of CTA, 18 of them revealed no endoleak or stent migration, and 1 patient of transection still had perfusion of distal false lumen at the abdominal aorta. None of the aortic segments measured in this study showed expansion of ≥5 mm during follow-up. The aorta remodeled well in 94.7% of them.ConclusionTEVAR for treating BAI appears feasible with high rates of technical and clinical success rates. The mid-term follow-up results seems satisfying, but the long-term results are yet to be assessed with further follow-up.
To explore the effectiveness and methods of intervention assistant operation in the treatment of phalanx closed fracture combined with artery crisis. Methods Between August 2002 and December 2008, 24 cases (31 toes) of phalanx closed fracture combined with artery crisis were treated. There were 17 males (22 toes) and 7 females (9 toes), aged from 16 to 62 years (mean, 38 years). The causes of injury included crush and bruise (20 cases), traffic accident (3 cases),and machine twist (1 case). The locations were the first toe (19 toes), the second toe (10 toes), and the third toe (2 toes). The period between injury and hospital ization was 1-10 hours (mean, 6.8 hours). Phalanx angiography was performed by using venous indwell ing needle for dorsal is pedis artery and posterior tibial artery puncture; according to angiography results, proper treatment could be done, then the constrast medium was injected to the artery to observe the blood supply. According to different types and locations of fracture, Kirschner wire and plate were choosen to fix fracture after the blood supply were recovered. Results Two cases (2 toes) received amputation due to necrosis at 4 days and 6 days after interventional therapy, respectively. Twenty-two cases (29 toes) survived. Incision healed primarily in 21 cases. Exudation occurred at wound of 1 case and was cured at 3 weeks after dressing change. Twenty-two cases (29 toes) were followed up 1-6 years (mean, 3.5 years) postoperatively. Two cases (3 toes) felt cool or anaesthesia and could not tolerate even in cold environment. The other toes had no senses of cold pain and paresthesia. Two cases (2 toes) had nonunion and achieved fracture heal ing after grafting bone. The mean union time was 4.5 months (range, 3-6 months) in other cases. Conclusion Intervention assistant operation is an effective measure in the treatment of phalanx closed fracture combined with artery crisis.
Drug addiction has been one of the serious social problems. The peripheral phlebitis caused by drug injection is common, but the occurrence of pseudoaneurysm with infection of femoral artery from injection injury was rarely reported in China. From January 1995 to March 1996, six cases of injury of femoral artery with infection from heroine injection were admitted. The characteristics of the injury were described. The therapeutic measures and details of attention to be needed were discussed. It was concluded that this type of injury was different from the injury caused in agricultural, industrial or traffic accidents. The treatment of choice depended upon the type of injury.
Abstract During 1960 to 1995, 19 of the 269 casesof arterial injuries in limbs treated developed ischemic contracture (7.06%), in which 14 in the lower limbs and 5 in the upper limbs. In the 19 cases, 3 injured arteries were not treated; 1 had his injured arteries repaired infailure; 5 cases had the concomitant veins injured, and 3 of them had their injured veins ligated in the primary treatment. Only 1 case received fasciotomy in his former treatment in other hospital. Four cases were admitted in our Institute in 14 hours, 8 cases were 34 to 57 hours and 7 were 19 days to 19 months after injury. Seventeen out of the 19 injured ateries and 5 out of the 8 injured vein were repaired. Eight cases received fasciotomy. The follow up ranged from 3months to 28 years (averaged 5 years). Sixteen out of the 17 injured arteries remained patent after repair, and the patency were proved by Bultrasound. The causes of ischemic contracture in these cases were analyzed. It was concluded that in order to prevent the limb from ischemic contracture, it should be emphasized that the accurate diagnosis of the injury of the artery and its concomitant ein be made early, the proper treatment be given to the injured artery and vein,and fasciotomy be done immediately as indicated.
