VIDEOENDOSCOPIC VASCULAR-SURGERY AT THE P ELVIC LEVEL IN ANIMAL TESTS- INTRODUCTION OF A NEW SURGICAL METHOD AND DEVELOPMENT OF LAPAROSCOPIC VASCULAR SURGICAL-INSTRUMENTS

In order to avoid the perioperative complications following convention al surgical treatment of aortoiliac atherosclerotic occlusive disease, taking advantage of the generally favourable postoperative recovery a fter endoscopic surgery, a new concept of videoendoscopic vascular sur gery and new instruments have been developed. Thus a standardized stud y on human cadavers and piglets was pel formed successfully finally en abling us to cary out two aortobifemoral arterial bypasses on two pati ents with iliac occlusive diseases. Even though it was possible to per form the endoscopic vascular method according to the rules of conventi onal vascular surgery, further experimental research and refinement of endoscopic instruments are still needed to optimize the new surgical method.
