title: False aneurysms following arterial reconstruction.
abstract: False aneurysms are increasingly being seen after the widespread utilization of arterial reconstructive surgical procedures involving implantation of prosthetic materials. The most common site of occurrence is the femoral location. The average interval between the primary procedure and the diagnosis of a false aneurysm in 42 months. THe exact cause remains uncertain, although multiple factors are most likely involved. these include degeneration of the host arterial wall, local endarterectomy, type of anastomosis, suture and graft material, various mechanical factors, hypertension and infection. Although small asymptomatic false aneurysms in easily accessible locations can be watched, a variety of complications, such as graft occlusion, rapid enlargement and rupture, venous and neural compression and distal embolization can occur. Early elective resection and repair are recommended in most patients.
