395 cases of peripheral arterial occlusion treated during 984 and 1994 hava been evaluated in this study. 190 of the patients were female and 205 were male, with an average age of 65 (22-93). The major concomitant diseases were: is chemic heart disease (52.7 %), hypertension (31.6 %), rheumatic heart disease (1.9 %), and myocardial infarction (12.9 %). Af1er the inital examination, 308 patients (78 %) were determined as acute embolus, and 87 (22 %) as acute thrombosis upon chronic vascular disease. Embolus localization (n: 308) was femoral in 54.9 %, popliteal in 21.8 %, brachial in 18.5 % and axillary in 4.8 %. The average duration between the onset of symptoms and presentation to the clinic was 52 hours. 2.1 % of the patients admitted within 12 hours required amputation, and 12.5 o/o died. These rates were 39.2 % amputation, and 37.7 % death for patients admitted later than 12 hours. 26 cases (29.9 %) out of 87 pa tients who were evaluated as acute thrombosis did not respond to medical treatment required surgery. Two patients in this group required amputation, and expired following the operation. We can state that it is crucial to differentiate be tween acute embolus and thrombosis in the initial examination, and also viability of the extremity in patients presenting later than 12 hours to the clinic should be determined with meticulous care due to increased mortality.
