The vascular bulge is due to the development of an aneurysm, which may be caused by a more pronounced dilatation of varicose veins, or by atherosclerosis of the arteries or congenital dysplasia of the arterial wall, which can cause dilatation of the arteries and lead to the development of an aneurysm. The patient’s history, physical examination and ancillary tests are needed to determine whether the bulge is an arterial or venous problem. If it is a venous problem, surgery can be performed to remove the venous aneurysm in its entirety. If the aneurysm is due to an arterial problem, the decision needs to be made on a patient-by-patient basis. If the arterial vessel is not very important, embolization of the aneurysm can be performed, and if the arterial vessel is more important, repair of the overlying stent can be performed.
