Seventy-four cases of peripheral arterial injuries in recent 30 years were reported. Mostof them were main arteies in extremeties. Twenty-eight cases were performed end to end anastomosis and 7 of them received amputation for various complications. We also performed 12 cases of reparatidn of wall, 20 cases of vascular grafts and 7 cases of arterial ligation. There were 16 cases of amputation and one death. We think that artemal injuries should be operated as soon as possible. Arteial reconstruction was mostly used, including reparation of wall, end-to-end anastomosis and autovenous graft. Other procedures should be emphasized, such as complete debridement of the soft tissue and vessels, appropriate fixation of fracture, exploration and reconstruction of major veins, enough decompression of interfascia compartment, proper drainage of would and good surgical skill. Local and general anticoagulation were good to treatment of arterial injuries during and after operation .
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.
Objective To summarize the experience in treatment and diagnosis of popliteal artery trauma and to determine the factors for amputation. Methods From February 1995 to January 2006, 28 patients with popliteal artery trauma were treated. The disease course was more than 8 hours. Of them, there were 25 males and 3 females, aging from 3 to 53 years. Trauma was caused by traffic accident in 12 cases, by falling from height in 3 cases, by firearm in 2 cases, by sharp instruments in 3 cases, by strangulation in 2 cases and by others in 6 cases. No arteriopalmus or weak arteriopalmus wereobserved in 18 cases and in 8 cases respectively. Popliteal artery exposure or active bleeding was seen in 2 cases; the popliteal arteries were examined by operation in 8 cases; color ultrasound Doppler flow imaging showed color flood flowsignals were through popliteal artery and its branches in 20 cases. Defect sizeof popliteal artery was less than 5 cm in 7 cases and more than 5 cm in 9 cases. End to end anastomosis reconstruction by saphenous vein graft and direct suture was performed in 16 cases and ampulation in 12 cases. The time of the revascularization of the leg was 8-150 hours (mean 31.8 hours). Results All patients were followed up 6 months to 11 years with an average of 4.2 years. In 16 cases given end to end anastomosis reconstruction, 15 cases achieved revascularization and limb survival; lower limb function restored to normal within 1 year in 12 cases; foot drop and ankle joint contracture occurred in 3 casesand the survival rate of limbs was 94%. Amputation was given in 12 of 28 casesbecause of severe trauma. The rate of amputation was 43% and the rate of disability was 54%. Conclusion Popliteal artery trauma should be treated as soon as the diagnosis is made. If the revascularization is more than 8 hours or circulatory compensation is not complete, it will affect the leg survival. Delayed diagnosis and severe traumas are the cause of high rate ofamputation in popliteal artery trauma.
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.
In order to develope a new method to overcome the difficulties in anastomosis of blood vessels with different diameter, phleboplasty was utilized at the join-point to expand the diameter of branched vein graft, with a funnel-shaped stoma formed consequently. After successfully experimented in fresh blood vessels in vitro, the method was practised clinically to repair injured arteries in extremities, with the outcome that phleboplasty of branched vein graft could enlarge the diameter by 1-1.25 times, and with satisfied effects in 3 clinic cases. So, the conclusion was that: phleboplasty of branched vein graft was a new effective and convinient method to repair injured arteries with different diameters
