(Semi-)closed endarterectomy in occlusive aortoiliac disease

Evaluation of the long-term results of a (semi-) closed endarterectomy of the aortoiliac segment with the use of the arterial disobliteration device.

From 1984 until 2005, a total of 157 patients (mean age, 53 years) with aortoiliac occlusive disease underwent a (semi-)closed endarterectomy of the aortoiliac segment. The primary operation indication was disabling claudication in 60.5% and advanced symptoms of ischemia or gangrene in 39.5%. The (semi-) closed endarterectomy was performed in 75% through a standard left retroperitoneal approach.

Mean follow-up time was 18.2 years. Primary patency was 96% after 5 and 92% after 10 years. Fourteen patients underwent a reintervention within 30 days. The operative 30-day mortality rate was 1.5%. A reintervention for recurrence of occlusive disease during follow-up was necessary in 22 patients. At follow-up after an average of 18.2 years, 105 patients were alive, with 52 not related deaths.

Retroperitoneal (semi-) closed disobliteration, with the use of the arterial disobliteration device, of the aortoiliac segment for stenotic and occlusive vascular disease is a safe and successful procedure the results of which are comparable with the implantation of a vascular aortic prosthesis. We consider this technique a valuable tool in vascular surgery.
