Arteriovenous fistula of the peroneal artery complicating a retrograde access: successful endovascular treatment with covered stent implantation.

ABSTRACT An 80-year-old woman developed a recurrent critical limb-threatening ischemia (CLTI) 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. A coronary balloon-expandable covered stent was deployed at the AVF site with complete resolution of the AVF. The final angiography demonstrated the patency of PA and PR with complete resolution of the AVF. The patient was discharged without complications, with regression of rest pain. The foot lesion healed within two months.
