The current role of preoperative arteriography in free fibula flaps.
The free fibula flap has become a "workhorse" flap for reconstructive surgeons, yet the indications for preoperative arteriography for the donor extremity remain unclear. Therefore, a retrospective review of all free fibula candidates over a 4-year period was conducted to clarify the need for preoperative arteriography. One hundred consecutive patients were evaluated as potential candidates for free fibula reconstruction. Twenty-one patients were deemed unsuitable because of associated comorbid conditions (15) or unusable limbs (6). The remaining 79 patients were candidates for fibula free flap reconstruction. Eight patients (10 percent) who had an abnormal lower extremity vascular physical examination (diminished or absent pedal pulses) underwent arteriography to evaluate the fibula donor site. Free fibula transfer was performed in 77 patients (mean age, 41; range, 3 to 80 years) to the following sites: mandible (65), upper limb (4), lower limb (6), and trunk (2). The overall free flap success rate was 99 percent. Results of arteriography included: normal three-vessel runoff (6), bilateral peroneal arteria magna (1), and bilateral posterior tibial artery occlusion with reconstitution via the peroneal artery (1). Two patients with unusable fibula donor sites (determination based on arteriographic findings) were reconstructed with ilium and radius. All others underwent uncomplicated free fibula transfer. Ischemic complications at the fibula donor site did not occur in any patient. This study supports the use of lower extremity vascular physical examination as the primary means of evaluating the fibula donor site. Routine preoperative arteriography is unnecessary and should be reserved for those patients with abnormal vascular examinations.
