Peripheral Aneurysm

Peripheral Aneurysm Aneurysms occur when part of an artery wall weakens, allowing it to balloon out or widen abnormally. Peripheral aneurysms affect the arteries other than the aorta. These are most commonly located in the legs. Symptoms of Peripheral Aneurysm Expand Content Most patients are asymptomatic, meaning they have no symptoms. Peripheral aneurysms generally do not rupture but may send a clot from within the aneurysm to the arteries downstream. Occasionally, this is a limb-threatening condition. Your vascular specialist will perform a complete vascular exam and may order further diagnostic tests if a peripheral aneurysm is suspected. Diagnostic Tests Expand Content Many tests are used to diagnose a peripheral aneurysm. Usually, more than one test is done before a definitive diagnosis can be made. These tests may include: Physical examination and patient history Duplex/doppler ultrasound Magnetic resonance imaging (MR) Computed tomography (CT) scan Angiography Treatment Options Expand Content Common treatment options for a peripheral aneurysm include: Continued observation for small aneurysm Conventional surgical repair (usually a bypass) Endovascular repair
