[Bypass operations in reconstructive vascular surgery, using prosthetic material (author's transl)].

Age and accumulation of risk factors in patients with arterial occlusive diseases in Fontaine's Stages III and IV do not always permit direct vascular reconstruction. A further indication for prosthetic bypass procedures is given by local infections following vascular surgical interventions, severe damage to soft parts after traumata and radiotherapy, and anus praeter in the pelvic region. In the supra-aortic region carotido-subclavian, subclavio-carotid and the carotido-carotid bypasses are already routine operations. The indications for axillo-femoral, carotido-femoral, femoro-femoral, iliaco-femoral and obturator bypasses are described and discussed with reference to our own experiences.
