An interesting case of chronic pulmonary thromboembolism caused by a femoral arterial aneurysm

Femoral artery aneurysm (FAA) is an unusual peripheral arterial aneurysm that can result in potential rupture, thrombosis and embolism. FAA can variably present as an asymptomatic mass or acute lower limb-threatening ischemia. We present a rare case of asymptomatic FAA causing proximal deep vein thrombosis, leading to chronic pulmonary thromboembolism. Endovascular intervention was performed to secure FAA. This report signifies FAA as a differential diagnosis of DVT and chronic pulmonary thromboembolism. Although an open surgical approach is generally preferred for FAA repair, minimally invasive endovascular repair can be considered a safe alternative technique.
