[Analysis of factors influencing on the surgical results of arterial embolism in the lower extremities].
130 patients with arterial embolism in the lower extremities underwent surgical treatment. The curative rate was 66.9%, amputation rate-19.2% and the mortality rate-13.8%. Statistical study showed that sex, age and recurrent embolism had few effects on the surgical results (P < 0.05). One of the influencing factors was the ischemic time of the lower extremities. The mortality rate was 33.3% in the distal abdomen with aortic embolism and 8.7% in the lower extremities (P < 0.005). The mortality rate and amputation rate were significantly higher in embolic patients with atherosclerotic stenosis and occlusion (9% and 17%). The mortality rate and amputation rate were 2.3% and 3.4% in patients with good blood flow and were 42.1% and 57.9% in patients without good blood flow uspectively. Reembolectomies showed no satisfactory effect. The results indicated that embolectomy combined with other necessary operations did not increase the mortality rate and amputation rate (P < 0.05). Postoperative anticoagulation therapy is extremely important.
