Operative results and outcome of twenty-four totally laparoscopic vascular procedures for aortoiliac occlusive disease.
OBJECTIVE
The study objective was to apply laparoscopic techniques to conventional bypass procedures for aortoiliac occlusive disease.


METHODS
From October 1995 to August 1997, we performed seven iliofemoral (IFB), five unilateral aortofemoral (UAFB), and 11 aortobifemoral (AFB) bypass procedures and one aortic endarterectomy (TEA) totally laparoscopic. A transabdominal approach with pneumoperitoneum was preferred, and only laparoscopic vascular instruments were used. Endoscopic intervention followed principles of vascular surgery. As in open surgery, we used Dacron grafts and polypropylene sutures.


RESULTS
Twenty procedures were carried out totally laparoscopic; four conversions to open surgery were necessary. Severe complications included one postoperative respiratory failure requiring ventilatory support for four days, and one iliac vein lesion with subsequent open surgery. Mean operating time was 258 +/- 49 minutes for IFB, 218 +/- 54 minutes for UAFB, 279 +/- 69 minutes for AFB, and 290 minutes for aortic TEA. Mean blood loss was 92 +/- 49 ml for IFB, 390 +/- 316 ml for UAFB, 563 +/- 516 ml for AFB, and 100 ml for aortic TEA. Mean postoperative stay was 7.4 days for IFB, 7.8 days for UAFB, and 10.1 days for AFB. After the aortic TEA, the patient was discharged on day 6. At control examination all grafts were patent; two patients had mild claudication because of one progressive disease and one distal suture stenosis.


CONCLUSIONS
Laparoscopic vascular surgery for aortoiliac occlusive disease is feasible, safe, and effective. At the beginning, a cooperation between experienced laparoscopists and vascular surgeons is needed to overcome procedural challenge, because operating time and conversion rate decrease with growing experience. The advantages observed in the majority of our patients were minimal tissue trauma, decreased blood loss, and faster postoperative recovery when compared with patients who had open aortic surgery at our institution. Further evidence has to be gained by clinical trials to define the role of laparoscopic vascular surgery for aortoiliac occlusive disease.
