Infected false aneurysms in the groin of intravenous drug abusers.
The hazards of dealing with infected false femoral aneurysms resulting from intra-arterial narcotic injection are highlighted in six patients. Two patients were human immunodeficiency virus positive and three patients were hepatitis B surface antigen positive. Because of these infections exploration of groin swellings as presumed soft tissue abscesses is potentially hazardous without proper proximal vascular control. All patients underwent reconstruction following arterial ligation and five grafts became infected, with life threatening haemorrhage occurring in four patients. Five grafts have subsequently occluded or have been removed without loss of limb viability, although two patients have been regrafted. A high index of suspicion and assessment by a vascular surgeon, with angiography if indicated, is required in any intravenous drug abuser presenting with a groin swelling following injection. Because of the great risk of graft infection, it is suggested that ligation and debridement alone be carried out, with immediate arterial reconstruction only for non-viability.
