Brachial, radial, and ulnar arteries in the endovascular era: choice of intervention.

To say that endovascular techniques have revolutionized treatment of aortic aneurysms is an understatement. These same techniques and principles are now being applied to peripheral aneurysms. Because of the small diameter of the arteries in the arm, the relative scarcity of true aneurysms of these arteries, and the fact that these arteries are readily accessible, open surgery remains the mainstay of therapy. On the other hand, nonsurgical approaches are playing an important role in the treatment of peripheral pseudoaneurysms and aneurysmal changes associated with arterial and venous access. This article reviews the natural history, treatment, and outcomes of aneurysms of the radial, brachial, and ulnar arteries. We will also focus on interventional treatment of pseudoaneurysms.
