Aorto-iliac reconstruction with special reference to the extraperitoneal approach

We have used the extraperitoneal approach for aorto-iliac reconstruction for lower limb ischaemia in over 130 patients. The operative exposure is excellent. Operating time is shortened and the upset to the patient much less than in the transperitoneal approach. We now believe that the method is suitable for use in the majority of aorto-iliac reconstructions. Patency rate 4 years after surgery for claudication is 89 per cent.
