Successful revascularization of the occluded anterior tibial artery using ultrasound-guided puncture of the occluded dorsal pedal artery: A case report with literature review

Abstract

A bidirectional approach is necessary for treating critical limb ischemia with complex, multiple lesions. We report an ultrasound-guided bidirectional puncture through an occluded vessel to treat an obstruction extending from the anterior tibial artery to the dorsal foot artery in a patient with toe gangrene and rest pain. This technique effectively restored arterial patency and is a promising approach for managing challenging critical limb ischemia occlusions.
