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.
