[Video endoscopic vascular surgery at the pelvic level in the animal experiment: introduction of a new surgical method and development of laparoscopic vascular surgery instruments].

In order to avoid the perioperative complications following conventional surgical treatment of aortoiliac atherosclerotic occlusive disease, taking advantage of the generally favourable postoperative recovery after endoscopic surgery, a new concept of videoendoscopic vascular surgery and new instruments have been developed. Thus a standardized study on human cadavers and piglets was performed successfully finally enabling us to carry out two aortobifemoral arterial bypasses on two patients with iliac occlusive diseases. Even though it was possible to perform the endoscopic vascular method according to the rules of conventional vascular surgery, further experimental research and refinement of endoscopic instruments are still needed to optimize the new surgical method.
