A 52-year-old man presented with
a pulsatile mass in the right groin. He had undergone lumbar
sympathectomy and aorto-right femoral artery bypass using an
8mm Microvel double velour graft, 14 years previously, for aortoiliac
occlusive disease caused by thromboangiitis obliterans. Based
on a clinical diagnosis of an anastomotic aneurysm, an operation
was performed. When the aneurysm was incised, it was found that
the anastomosis of the graft to the femoral artery was intact
and that the graft itself had a defect, 3cm in size on the anterior
wall, 1.5cm proximal to the distal anastomosis. The final diagnosis
was a nonanastomotic false aneurysm due to prosthetic graft failure.
The failed portion of the graft was resected, and a 10mm Hemashield
Gold woven double velour graft was interposed between the old
graft and the right femoral artery. Generally, arterial grafts
below the groin are subject to high levels of mechanical stress,
and graft failure is not uncommon. Vascular surgeons should keep
in mind that graft failure is not rare in patients with long-standing
prosthetic grafts.
