[Formalin preserved allogenic veins for arterial replacement (author's transl)].

Allogenic saphena magna and umbilical vein grafts can be successfully used for vessel replacement and dialysis shunts. The chemical preservation with 4% buffered formalin is to be recommended as a preservation procedure, since the preparation of the vein grafts can take place aseptically and without the occurrence of immunologic rejections. The conservation procedure is simple, inexpensive and possible everywhere without elaborate technical equipment. The dissecting technique and preparation is demonstrated in detail.
