To study methods of salvage therapy for acute lower extremity(ALEI) ischemia. Methods:A restrospectively analyzsis was made on the clinical data of 96 patients with consecutive 106 ALEI limbs. In which Fogarty catheter embolectomy was used as the initial treatment for ALEI in a regular operating room or in an intervention therapy room under DSA monitoring,and graft bypass after embolectomy was performed on 8 cases(12 limbs). Results:In 70 cases(75 limbs) successful embolectomy of the iliac，femoral，popliteal and tibial artery was achieved. In 11 cases(12 limbs) embolectomy at distal to the popliteal artery was unsuccessful. Eight cases(12 limbs) with obstruction proximal to the femoral artery were treated by axillofemoral bypass in 4 cases, and femorofemoral bypass in 4 cases. One case of thoracoabdominal aortic dissection aneurysm and lower extremity ischemia had fenestration of the abdominal aoric dissection. Proximal embolectomy and distal amputation was performed in 6 cases. Fimally, 76(79.2%) cases had salvaged limbs,11(11.4%) patients had amputated limbs, and 9(9.4%) patients died. Seventy-six patients(85 limbs) were followed up for 1 to 38 months, 7 cases(7 limbs) were reoperated on because of recurrent embolism. Conclusions:Embolectomy is the effective treatment method for ALEI. Embolectomy under DSA monitoring can improve therapeutic results. The prognosis lies on the duration and extent of ischemia, and management of complications.
