Disruption of proximal aortosaphenous vein anastomosis. Late complication of aortocoronary bypass surgery.

Abstract

A 43-year-old man who had undergone aortocoronary saphenous vein bypass developed disruption of the proximal aorto-saphenous vein anastomosis. Although rare, a mediastinal hematoma secondary to leakage or disruption of an anastomotic site should be considered in patients who develop a mediastinal mass after aortocoronary bypass surgery.
