Ring avulsion injuries managed with homodigital and heterodigital Venous Island Conduit (VIC) flaps.
Ring avulsion injury frequently results in vascular insufficiency (venous or arterial) and soft tissue injury. We report four cases requiring revascularization where venous congestion and dorsal skin cover were achieved using a composite pedicled venous flow-through flap. We have termed this a Venous Island Conduit (VIC) Flap. Two types of flaps, homodigital and heterodigital, were used, depending on the severity of the injury. The techniques and results are discussed. Venous island conduit flaps are ideally suited to the management of ring avulsion injury and have several advantages over the alternatives.
