Treatment of severe lower extremity ischemia with distal bypass and arteriovenous anastomosis / 中国普通外科杂志

ABSTRACT

ObjectiveTo explore the effectiveness o f distal arterial bypass for the treatment of severe lower limb ischemia with p oor outflow artery. Method From July 2000 to Dec 2004, we treated 21 cases (21 limbs) of severe lower limb ischemia with poor outflow artery by distal bypass with additional arteriov enous anastomosis at or distal to the distal graft anastomosis. Results Among the 21 cases, one case recei ved reoperation for “void arterial perfusion” distal to the arteriovenous anas tomosis. The operative success rate was 95.2%.The patency rate of graft was 100 % and the healing rate of foot ulcer was 33.3% on discharge. Conclusion Additional areriovenous anastomos is at or distal to the distal graft anastomosis can dramatically increase the pa tency rate of the graft when outflow artery is too poor to guarantee a patent gr afting in the case of severe lower limb ischemia, although long-term effectiven ess needs to be varified.
