Laparoscopic aorta surgery

摘要

abstract_textpThe following article describes our technique and results with total laparoscopic aortic aneurysm repair. A distinction must be made between laparoscopic-assisted procedures requiring a mini-incision to perform an anastomosis and total laparoscopic operations where the whole procedure is performed laparoscopically. In addition to aorto-femoral or ileo-femoral bypass procedures, total laparoscopic techniques can be used to perform abdominal aortic aneurysm resections. A transperitoneal left retrorenal access is preferred in most cases. Special laparoscopic clamps, often in combination with balloon catheters are used to occlude the aorta and if necessary the renal arteries. Exactly the same techniques as used in open surgery are transferred to a laparoscopic setting. Either a tube graft repair or a bifurcated graft anastomosed with the iliac bifurcation or the femoral artery is performed to exclude the aneurysm. Laparoscopic techniques can also be used to treat patients with type II endoleakage after EVAR or cases with endotension. Lumbar arteries or the IMA are clipped and if necessary downsizing of the aneurysm can be accomplished by opening the sac of the AAA, evacuating the thrombus material and stitching lumbar arteries from the inside. More recently laparoscopic techniques have been used to reduce the access trauma in debranching procedures. The learning curve of total laparoscopic aortic procedures is still steep, but new instruments, staplers or robotic devices will probably shorten this learning curve in the future. In an increasing number of European countries laparoscopic aortic surgery is becoming a third way to perform aortic repair. In contrast to EVAR it can offer to aneurysm patients the same definitive outcome and long lasting results as open surgery./p/abstract_text
