There were 8 patients suffering from rest pain and 15 patients presented with tissue loss and the ABI for cases with reliable measurements was ranging from 0.35 to 0.6 with a mean ABI of 0.49. The pattern of arterial pathology was a multilevel occlusive disease where a mixed supra inguinal and infra inguinal disease was found in 10 cases, three of them were having an aortoiliac pathology and the other seven were suffering from iliac artery pathology in conjunction with infra inguinal disease while in thirteen cases there was an infra inguinal complex pathology where different mixtures of CFA, SFA, popliteal and tibial pathology was found as the CFA was occluded in 7 patients, 20 patients were having SFA lesions and 11 patients showed popliteal / tibial disease.
