Medial-to-lateral plantar loop technique for retrograde transcollateral recanalization of the lateral plantar artery in patients with type 3 plantar arch.

A 89-year-old male presented with severe untreatable pain and ischemic non-healing ulcer in the left forefoot. The pre-procedural angiograms showed multiple stenosis of the superficial femoral and popliteal arteries, occlusion of anterior tibial artery, tibio-peroneal trunk (TTP) and distal posterior tibial artery (PTA), stenosis of the peroneal artery, and the patency of the medial plantar artery (MPA) as a single pedal artery, with very poor perfusion of the lateral aspect of the forefoot. The TTP and PTA were recanalized, and balloon angioplasty of superficial femoral artery and popliteal artery and peroneal artery was carried out.

Retrograde Deep Femoral Artery Access as Bailout Technique to Rescue Unexpected Ostial Occlusion during Antegrade Superficial Femoral Artery Recanalization.

We report a case of deep femoral artery (DFA) retrograde access for recanalization of an accidental ostial occlusion complicating an antegrade-retrograde superficial femoral artery (SFA) procedure. A 77-year-old man with chronic limb-threatening ischemia of the right lower limb was submitted to a duplex ultrasound that showed a heavy calcified SFA chronic total occlusion. During antegrade and retrograde attempts to cross the SFA obstruction, a control angiogram unexpectedly showed the ostial occlusion of the DFA.

Arteriovenous Fistula of the Peroneal Artery Complicating a Retrograde Access: Successful Endovascular Treatment with Covered Stent Implantation.

An 80-year-old woman developed a recurrent chronic limb-threatening ischemia of the right lower limb after a popliteal artery (PA) recanalization with retrograde puncture of the peroneal artery (PR). The angiography showed the PA restenosis and an arteriovenous fistula (AVF) at the previous peroneal retrograde access site. After the PA angioplasty, the AVF was identified through selective contrast injections in multiple projections.
