[The femoro-crural venous bypass in chronic arterial block of the leg (author's transl)].

A report on 58 reconstructive vascular operations in chronic blocks of arteries of the leg. 4 different types of block in these arteries can be distinguished. Operation is indicated only in severe disturbances of circulation of stage III and IV. The criterion for reconstruction is not found in the proximal part of the arteries. Angiographic proof of at least one leg-artery down to the periphery being patent and permitting free flow is required. The various techniques applicable to each type of block, early and late results are reported on. Suring a period of up to 3 years block recurred in 26%. Most recurrences (46%) were seen within the first 30 days.
