[By-passes of the arteries in the leg and the foot (author's transl)].

The author presents the 50 first cases of his serie of by-passes on legs and feet arteries. The various stages of the angiography, anesthesia and operation technique are discussed. The results are divided into three groups; the by-passes always permeable, the patients deceased from another disease still with a permeable by-pass, and the precocious or late failures. The latter are studied more in detail in order to bring out, the reasons of failures and the factors which could improve the present results. The analysis of the results, compared to those of the published cases, shows a satisfying percentage of good results, seen the symptoms and lesions.
