42 vascular reconstructive procedures, concerning occlusions in full length of the trifurcation of the lower limb, were carried out in 40 patients. The success-rate was unsatisfactory. It was as low as 55% after 30 days and 25% after 28 months. This is thought to be due to wrong indication and unfavorable operative proceedings. The high hospital letality of 12%, observed in aged persons only, may be reduced by improving post-operative care. It is stressed that any bad result of this kind of vascular surgery is connected with a high vital danger to the patient in question. Avoiding pre- and intraoperative unfavorable factors is rewarded by better early result; thus it is not the method itself but its wrong application which is bad.
