The treatment of vascular trauma is a challenging and increasingly successful endeavor. Improvement in patency rates and limb salvage have occurred through advances in diagnostic methods, materials for vessel replacement and techniques of repair. Several principals have evolved. An aggressive diagnostic approach is indicated with early arteriography in all suspicious injuries. Distal blood flow should be established as soon as possible. Associated venous injuries should be repaired if possible. Unstable orthopedic injuries shoud be stabilized conservatively with minimal internal wire fixation of fragments and the use of traction. Fasciotomy should be used in treatment of any injury involving prolonged ischemia of distal tissues.
