Case report: Deep vein arterialization for limb salvage in a patient with subacute limb ischemia.

ABSTRACT

BACKGROUND: Successful revascularization of the lower extremity is key to avoiding amputation in patients with subacute limb ischemia. Percutaneous deep vein arterialization (DVA) is a novel endovascular technique which allows the shunting of blood through an arteriovenous fistula and native vein into the lower limb, typically employed in no-option chronic limb-threatening ischemia. METHOD: We present a case illustrating the unconventional use of DVA for limb salvage in a patient presenting with subacute limb ischemia refractive to surgical treatment, endovascular revascularization, and medical therapy. RESULT AND CONCLUSION: The arteriovenous anastomosis allowed for the reconstitution of arterial inflow to the patient's foot, thereby avoiding major limb amputation. CONCLUSION: The conventional knowledge that DVA neo-conduits require maturation limiting its role in the treatment of subacute limb ischemia is challenged. However, further research is needed to establish its role and effectiveness for subacute limb ischemia.
