Sort: Oldest first
Those having a venous sac, connecting with a vein on one side and an artery on the other, called aneurismal varix; those having a false sac without direct communication with vein or artery called varicose a; and the rare form occurring when a true arterial a. erodes the wall of a vein and ruptures into it, called arteriovenous a. with arterial sac. Arteriovenous a. is usually due to punctured wounds and the vessels usually involved are the following in the order of frequency given: brachial, femoral, popliteal, carotid, arteries of the head, especially the temporal and the subclavian and axillary arteries.
