Salvage of a devascularized digit with free arterialized venous flap: a case report

Significant soft tissue and vascular loss is always encountered in salvage of a devascularized digit that has sustained crush or avulsion injury. Ideal reconstruction should include repair of the vascular defect and provision of stable soft tissue coverage simultaneously in a single operation to facilitate early recovery and early rehabilitation. A venous flap is a composite cutaneous flap that contains a segment of vein traversing it. A free venous flap is used in a devascularized digit to cover the soft tissue defect and restore the digital circulation by perfusion of arterial blood through the flap's venous network (i.e., free arterialized venous flap). Satisfactory result, both for the flap and for the digit, is obtained. The free arterialized venous flap is a useful, up-to-date option for such dual-purpose reconstruction.
