A peripheral arterial aneurysm is characterized by bulging in one or more peripheral arteries due to weakened internal arterial walls. The leg and neck arteries are the most common peripheral arteries involved in arterial aneurysms. The risk factors include smoking, family and medical history of an aneurysm, and underlying connective tissue disorders."Vascular & Endovascular Surgery and Interventional Radiology"
