Retrograde endovascular intervention treating chronic limb threatening ischemia: A case report

Abstract

The retrograde approach is an adjunctive technique for endovascular intervention, particularly in the treatment of lower extremity arterial disease with multilevel vascular lesions. Combined with revascularization therapy, wound care plays a pivotal role in the management of patients with chronic limb-threatening ischemia. We present a case of chronic limb-threatening ischemia, with complex multilevel vascular lesions successfully treated using a retrograde endovascular approach alongside aggressive wound care management. Postintervention, the patient demonstrated a notable increase in ankle-brachial index from 0 to 1, along with accelerated wound healing and preservation of limb function. This case highlights the efficacy of the retrograde approach in restoring perfusion, particularly in chronic total occlusions, and emphasizes the importance of combining revascularization and wound care for optimal chronic limb-threatening ischemia management.
