False Aneurysm of the Deep Femoral Artery as a Complication of Intertrochanteric Fracture of the Hip: Options of Open and Endovascular Repairs

Abstract

A quarter of all intertrochanteric fractures are unstable with a fractured lesser trochanter. Mostly these fractures are treated with a gamma nail fixation. A rare complication of this treatment is a false aneurysm of the femoral artery. The authors present 2 cases of a false aneurysm of the femoral artery in association with intertrochanteric fractures. Because of its nonspecific symptoms, a false aneurysm is difficult to diagnose. A computed tomography angiography or duplex should be used to confirm the diagnosis and evaluate the options for treatment. Surgery is the preferred treatment in the case of a large aneurysm, whereas endovascular repair is preferred for smaller aneurysms.
