A "blush sign": radiological harbinger of delayed pseudoaneurysm formation after vein graft angioplasty

Vasc Endovascular Surg. 2013 Nov;47(8):656-9. doi: 10.1177/1538574413500537. Epub 2013 Aug 12.

Abstract

Vein graft stenosis is a well-recognized complication of infrainguinal bypass surgery. Balloon angioplasty is an accepted method for managing vein graft stenosis in selected patients. This intervention is not without complication. We present 2 cases of delayed pseudoaneurysm formation after balloon angioplasty of vein graft stenoses. Both cases showed a persistent contrast stain or blush as an indication of vein wall damage and propose that this is a radiological harbinger of delayed rupture and pseudoaneurysm formation.

Keywords: balloon angioplasty; contrast stain; infra inguinal bypass; pseudoaneurysm; vein graft rupture; vein graft stenosis.
