Ischaemic Lumbosacral Plexopathy Following Aorto-Iliac Bypass Graft: Case Report and Review of Literature

摘要

A 77-year-old man had aorto-iliac bypass for an abdominal aortic aneurysm (AAA). This was complicated by occlusion that needed extension of the graft to the right femoral artery. He was unable to move his right leg with numbness after surgery. This was caused by extensive lumbosacral plexopathy on the right side. Lumbosacral plexopathy is uncommon because the plexus has a rich blood supply. The incidence of ischaemic lumbosacral plexopathy is higher with re-operative and emergency AAA reconstruction. This may predispose the lumbosacral plexus to ischaemic injury. Consideration should be given to maintaining retrograde perfusion of the internal iliac artery.
