[Mixed dacron-vein bypass. Apropos of 33 cases]

The use of a mixed dacron-vein by-pass is a technical device permitting one to palliate the impossibility of using exclusively venous material. 33 by-passes were thus carried out:--30 distal by-passes;--3 proximal by-passes. The interest of this technique is the possibility of implanting on a small caliber artery, e.g. profunda femoris, popliteal or femoral artery. The main technical point is the immediate anastomosis. Since this article was drawn-up, the indications for this procedure have been multiplied and, over a period of six months, we carried out 32 new mixed by-passes.--27 proximal by-passes;--5 distal by-passes.
