Quick Take: Transcatheter Arterialization of Veins for Limb Ischemia

ALT Figure 1. Key Procedural Steps for Transcatheter Arterialization of the Deep Veins. The steps for transcatheter arterialization of the deep veins in the lower leg involve obtaining ultrasound-guided pedal vascular access (Panel A); advancing the needle into the mesh cage for establishment of arteriovenous crossing (the needle is in the arterial system and advances through the artery into the vein; the basket is in the vein) (Panel B); rendering venous valves incompetent with a push valvulotome (Panel C); deploying a straight covered stent at the level of the calcaneus (Panel D); and lining the vein with straight stents before placing a tapered, self-expanding, covered stent across the arteriovenous crossing to establish arterial blood flow in the venous system (Panel E).
