Arteriography of lower limbs with blocked circulation: ("dry-limb" arteriography).

The author describes a simple technique for arteriography of lower limbs with blocked circulation. Through either an antegrade or retrograde femoral approach, a balloon catheter with a double lumen is inserted and used to produce an arterial occlusion. Arteriography is then performed. With this technique, small peripheral thrombi can be identified and all arteries of the leg, as well as collateral circulation, can be studied.
