Transluminal iliac angioplasty with distal bypass surgery in patients with critical limb ischaemia

Transluminal balloon angioplasty of the iliac artery was combined with a distal bypass graft procedure in 25 patients with critical ischaemia of the lower limb. Eleven patients had angioplasty in the operating theatre before a vascular graft and the remaining 14 patients had percutaneous transluminal angioplasty performed in the X-ray department before bypass surgery. The distal bypass grafts were 20 femoropopliteal and five femorofemoral grafts. Two patients died in the immediate postoperative period. Follow-up of patients ranged from 2 to 26 months with a graft patency of 63% at 12 months and 50% at 24 months but successful limb salvage rate of 75% at 12 and 24 months. Six patients required major amputations for failure of limb salvage. Transluminal iliac angioplasty is a valuable adjunct to distal bypass surgery by improving arterial inflow without the requirement for major aorto iliac surgery.
