[Microvascular flap surgery in arterial occlusive disease].

In the elderly, occlusive arterial disease is a contributing cause of posttraumatic soft-tissue defects of the lower limb. The reconstructive possibilities by microsurgical flap transplantation available are presented on the basis of 22 patients treated. Four failures were due to an almost or completely occluded peripheral outflow. Vein bypass was combined twice with an arterio-venous fistula, but occluded nevertheless.
