Management of lower extremity arterial injuries

Past and current military experience has contributed considerably to the advances made in the treatment of extremity vascular injuries. However, the management of arterial injuries of the lower extremity is still associated with significant rates of limb loss and functional deficits. The incidence of civilian arterial limb injuries, including those related to iatrogenic vessel catheterization, has increased over time, but remains fortunately uncommon. Several related issues, such as the initial order of intervention for associated bony injuries, use of temporary intravascular shunt, repair of concomitant venous injuries, and prophylactic fasciotomy, have been debated extensively and remain controversial. The current treatment of extremity arterial injuries continues to evolve with the availability of superior imaging modalities and emerging endovascular technology. Additionally, the multi-disciplinary approach to the injured patients has produced improved limb-salvage and patient survival. In this review, we discuss the diagnostic evaluation, surgical and endovascular treatment of arterial injuries in the lower extremity.
