Management of Open Vascular Injuries in the Lower Extremities (Report of 25 Cases）

ObjectiveTo discuss the diagnosis, treatment and clinical characteristics of open vascular injuries in the lower extremities and summarize our experiences. Methods To review the records of patients sustained an open injuries to the lower extremities vessel between 1999 and 2001 retrospectively. The clinical, operative findings and prognosis were collected and studied.ResultsAll 25 patients received emergency surgical treatment to repair the vascular injuries. It included 18 with isolated arterial injuries and 7 with combined arteriovenous injuries. Saphenous vein grafts were placed in 5 patients and vascular prostheses were placed in 5 patients with arterial injuries.Twentyfour patients were cured (96%), and 1 graft obstruction occurred (could not be contacted 40 days after operation). ConclusionOpen vascular injuries in the lower extremities should be diagnosed and treated as early as possible. The aim of the operation is to repair or reconstruct the injured vessel and to lower the mortality and morbidity rate.

Progress of Non-Invasive Arterial Measurements and Evaulation of Cardiovascular Injury of OSAHS

阻塞性睡眠呼吸暂停低通气综合征( OSAHS) 是心血管疾病的独立危险因素[1,2 ]。睡眠过程中反复发生氧饱和度降低和频繁觉醒是心血管损伤的病理生理基础。OSAHS 血管损害的早期改变可表现为血管僵硬度增加, 对亚临床血管病变患者开展早期动脉弹性功能检测及早进行干预, 可有效预防心血管疾病的发生。本文就常用的无创动脉硬化检测lt;br /gt;技术及其对OSAHS 心血管损伤的评估相关研究进展进行综述。

DIAGNOSIS AND TREATMENT OF VASCULAR INJURY IN LIMBS

To report the diagnosis methods and cl inical treatment effects of blood vessel trunk damage in l imbs. Methods From January 2001 to June 2006, 72 patients with vascular injury in l imbs were treated. There were 50 males and 22 females, aged from 5-60 years (median 39 years) and including 44 cases of open injury and 28 cases of closed injury.The locations were subclavian artery in 1, femoral artery in 23, popl iteal artery in 20, radia artery and ulna artery in 12, brachial artery in 11, axilary artery in 3 and anterior and posterior tibia artery in 2. The disease course was 30 minutes to 27 days. Injured arteries were repaired by suturing directly in 3 cases, by end-end anastomosis in 39 cases and by saphenous transplantation in 30 cases. The length of transplant veins was 3 cm to 8 cm. Results In 72 cases, 67 survived and 5 were given amputation. Fortyeight cases were followed up 6 months to 5 years. The blood flow rate and the diameter of blood vessel on the affected l imbs were not different from that of normal l imbs by colorful Doppler blood flow monitor. Forty cases recovered satisfactory l imb function. Eight cases had different degrees of dysfunction, of them, four cases received functional reconstructive operation, and the function and appearance were improved. Conclusion To investigate the mechanism and situation of injury, to examine patients carefully and analyze comprehensively are the key points of making earl ier diagnosis for branch blood vessel damage; microsurgical repair of the injured blood vessel is the assurance of the blood flow rate. For the blood vessel above elbow and knee injured and lacked blood supply more than 4 hours and fascia syndrome, earl ier opening the fascia cavity is the effective methods to recover the function of the l imbs and to avoid disabil ity.

四肢主要血管火器伤的修复重建

对40 例四肢主要血管火器伤患者的临床资料进行回顾性分析，总结损伤的有效救治方法。 方 法 1986 年5 月－ 2006 年11 月，收治40 例四肢主要血管火器伤患者。男35 例，女5 例；年龄16 ～ 50 岁，平均31. 2 岁。动脉完全断裂16 例，动脉部分断裂6 例，动脉缺损14 例，动脉血栓形成2 例，假性动脉瘤2 例。病程12 min ～ 20 h。彻底清创、充分减压和引流，根据不同情况选择自体静脉移植25 例，人造血管移植3 例，血管吻合6 例，血管修补4 例，带血管蒂的轴型皮瓣游离移植2 例。 结果 经抗感染、输血补液及抗凝、扩张血管等治疗，死亡1 例，截肢2 例，肾衰竭截肢1 例，成功修复36 例。伤口Ⅰ期愈合29 例，Ⅱ期愈合7 例。经7 个月～ 2 年随访，修复血管均恢复通血，肢端血运良好，动脉搏动正常，按英国医学会感觉运动功能评定标准：优28 例，良6 例，差2 例。 结论 “生命第一、肢体第二”是四肢主要血管火器伤的救治原则，采用自体静脉或人造血管旁路移植修复可获良好效果。
