Arterial embolism of the legs. A follow-up study of 252 patients.
This retrospective study of 279 embolectomies in 252 patients shows a mortality of 27%, and an amputation rate of 15% within the first month after the embolectomy. The mortality as well as the rate of amputations decreased through the first year. After this period the mortality was comparable to that of a normal population and the rate of amputation was negligible. The mortality rate as well as the number of amputations increased with increasing time-lag of the embolectomy. In addition, the rate of amputation increased with preexisting intermittent claudication. There was no significant difference in amputation rate between limbs with and without palpable pulsations in the groin on admission, but 8 out of 103 limbs without groin pulsations had successful major vascular reconstruction performed after failing embolectomy in contrast to none in the group where pulsations were present. In 28 patients the embolectomy was followed by impairment of renal function and 14 of these died. It is concluded that embolectomy must be performed as early as possible, vascular reconstruction must be considered if the embolectomy fails to revascularize the limb, preventive measures should be taken against renal failure, i.e. the myonephropathic-metabolic syndrome.
