Vascular complications in orthopedic surgery.
Vascular complications may be seen secondary to trauma or in the perioperative period following elective surgery. Prompt recognition and correction of these problems are of utmost importance to assure functional viability of the affected extremity. Evaluation may be complicated by the presence of preexisting atherosclerotic occlusive disease in the elderly patient. Relevant points in the history and physical examination include mechanism of injury, preexisting disease, evaluation of motor and sensory function, and presence and character of pulses. Noninvasive vascular studies should be obtained in all patients. Absolute indications for angiography include absent pulses, signs and symptoms of ischemia, a bruit, and a posterior knee dislocation; decreased pulses, a significant hematoma, and proximity of the fracture fragment are relative indications. Controversial issues in the management of combined orthopedic and vascular injuries include the use of internal versus external fixation, the use of prosthetic versus autogenous material, and the need for venous reconstruction. Popliteal artery trauma is still associated with a high limb loss rate, and careful evaluation of knee injuries is necessary. Vascular compromise may also complicate joint replacement surgery. These complications are preventable, and management is greatly simplified by a detailed preoperative evaluation.
