Abstract
Deep vein arterialization (DVA) is a therapeutic option in “no option” for revascularization chronic limb-threatening ischemia patients, creating an arteriovenous bypass between a proximal artery and a distal deep venous target at the ankle. Imaging plays a crucial role in peripheral arterial disease (PAD) patient management. We present the case of a 71-year-old PAD patient (Rutherford class 5) with focal gangrene of the first and second toes of the right foot, who was admitted to the vascular surgery department to undergo revascularization surgery by femoro-tibial artery bypass. During surgery a DVA was performed because of an unsatisfactory distal artery target. The post-operative computed tomography angiography showed the saphenous graft patency and opacification of distal foot veins. Subsequent angiography documented the presence of a large venous collateral, responsible for extensive early wash-out to leg venous vessels, which was then embolized. After two months, the patient underwent amputation of the right first and second necrotic toes at the level of the metatarsophalangeal joints. The post-operative course was excellent, with disappearance of pain at rest and good trophism of the surgical wound.
