Endoskopische aortofemorale Bypassrekonstruktion

TL;DRAbstract

According to the present experiences, the new videoendoscopic vascular instrument systems have fulfilled the basic requirements for performing videoendoscopic aortoiliac surgery. The animal studies (n = 25) showed clearly, that the piglet is a reproducible and favourable model to acquire the basic surgical techniques for videoendoscopic aortoiliac surgery, since its retroperitoneal anatomy is similar to that of humans. The transabdominal-retroperitoneal approach on human cadavers (n = 6) was soon abandoned, since particularly in obese cases it caused burdensome sliding of the intestine into the operative field adjacent to the renal vessels. The intensive investigations on human cadavers (n = 20) has meanwhile allowed us to constantly expose the aorta above the inferior mesenteric artery up to the left renal vessels without the need to sacrifice the inferior mesenteric artery (total operating time: 3-4.5 hours, aortic reconstruction averagely 42 minutes). The prolonged operating time du
