[Acute arterial occlusion of the extremities. Rate of success following simple embolectomy and following combined procedures].

Acute arterial obstruction of the extremities represents the most common emergency in vascular surgery. Diagnosis is based on the typical history and clinical symptoms. Emboli in vessels without atherosclerotic changes can be removed by simple embolectomy. In atherosclerotic arteries or in cases of acute thrombotic occlusion preoperative angiography is recommended in order to perform extensive reconstructive procedures. 400 arterial reconstructions for acute obstruction of the extremities were analysed. 46 operations were done in the upper extremities. In the majority of the cases simple embolectomy was successful. Limb salvage was 100% although one embolectomy and one bypass procedure failed to restore full revascularization. Complication and mortality rate was low. 354 lower limbs were operated. 274 extremities could be saved (77.4%). Among 80 poor results 48 major amputations had to be done (13.5%). Perioperative mortality was 12.4%. Death was mainly attributed to myocardial infarction.
