Methods: Between February 1985 to September 2002, 318 patients (186 male and 132 female) with a mean age 56.5 ± 13.3 years (ranged 3 to 84 years) were analyzed. Only 204 patients (64.2%) were admitted to hospital with in 12 hours, the other 114 patients (35.8%) over 12 hours after acute occlusion. The occlusion sites were femoro-popliteal region (74.8%), followed by brachial (18.8%), inferopopliteal and distal (4.4%), iliac (1.9%) regions. The most frequent reasons of the occlusions were cardiac in 208 cases (67.1%).

Results: Reembolectomy required in 8.5% cases that occured after upper extremity embolectomy in 5 cases and lower extremity embolectomy in 22 cases. Faciotomy was done in 15 cases (4.7%),all occured after lower extremity procedures. Amputation of relevant extremity, 6 of them above knee and 9 of them below knee, after demarcasion were performed in 15 cases (4.7%).

Conclusions: Acute arterial occlusions are serious clinical entity require early diagnosis and urgent surgical interventions for preventing high mortality and morbidity.
