简介
Purpose
To detail a percutaneous technique for distal plantar venous arterialization in diabetic, end-stage renal disease (ESRD) patients with no-option critical limb ischemia (CLI).
Technique
After failure of standard intraluminal recanalization attempts, a subintimal approach through the posterior tibial artery (PTA) is begun using a 0.014-inch, 190- or 300-cm-long guidewire supported by a 2-×20-mm, low-profile balloon catheter positioned a short distance behind the narrow “U-shaped” loop in the guidewire. Typically, heavy calcification in the distal tortuous segment of the PTA prevents reentry to the arterial true lumen; however, an entry in the distal lateral or medial plantar vein from a subintimal channel in the plantar artery can be intentionally pursued as a bailout technique, pointing the tip of the guidewire opposite to the arterial wall calcifications. Venous access is confirmed by contrast injection through the …
