一期静脉动脉化血运重建治疗四肢广泛性动脉闭塞性缺血

REVASCULARIZATION OF LIMB BLOOD SUPPLY BY ARTERIALIZATION OF VEIN IN EXTENSIUE ATERIAL OBLITERY ISCHEMIA

目的 探讨静脉动脉化血运重建对四肢广泛性动脉闭塞性缺血的疗效。 方法 1 999年 5月～ 2 0 0 1年 8月 ,对有慢性缺血表现的 1 8条下肢和 6条上肢行彩色多普勒超声和数字减影血管造影检查 ,确诊为广泛性肢体动脉闭塞症。根据闭塞平面采用原位高位浅组静脉或低位深组静脉一期静脉动脉化重建血运手术对患肢进行治疗。 结果 术后住院期间除 1条下肢截肢外 ,1 7条下肢和 6条上肢获 3～ 2 6个月随访 ,其中 1条下肢出院 3个月后患肢趾缺血坏死再入院行低位截肢 ,其余 1 6条下肢和 6条上肢疗效满意 ,症状消失。术后彩色多普勒超声复查可见动脉血向缺血肢体灌注。 结论 根据闭塞平面采用高位浅组或低位深组一期静脉动脉化重建血运 ,治疗四肢广泛性动脉闭塞简便易行 。

Objective To investigate the effect of arterilization of veins in treatment of extensive arterial oblitery ischemia of limbs . Methods Eighteen lower limbs and six upper limbs with symptoms of chronic ischemia were diagnosed as having extensive occlusion of the major arteries by color Doppler Ultrasonic Scanning and DSA. According to the level of occlusion, the involved limbs were treated by arterilization of veins in one stage. Results During hospitalization, one lower limb was amputated. Seventeen lower limbs and six upper limbs were followed up for 3 to 26 months. Among them, one lower limb was amputated for necrosis of toes after 3 months; the outcomes of the others were satisfactory. By Doppler scanning, the arterial blood flow was observed after operation. Conclusion Arterilization of veins in extensive arterial oblitery ischemia of limbs is a simple and effective treatment with good result.
