Use of fibula-free tissue transfer with preoperative 2-vessel runoff to the lower extremity
1Department of Otolaryngology--Head and Neck Surgery, University of Texas Southwestern Medical Center, Dallas, USA.
Objective:
To present our experience with fibula-free tissue transfer in patients with documented 2-vessel runoff to the lower extremity on preoperative angiography.
Methods:
A case series of 16 patients with segmental mandibular defects reconstructed with a fibula-free flap by the senior author with 100% stenosis of the anterior or posterior tibial arteries were retrospectively reviewed for radiographic data and complications.
Results:
All flaps performed were successful, and there were no donor site complications. Angiography documented flow of contrast to the foot by a patent anterior or posterior tibial artery in all patients. Occlusive arteriosclerotic disease was identified in the anterior tibial artery in 10 patients and in the posterior tibial artery in 6 patients.
Conclusions:
Using our specific criteria, we experienced no complications with the use of a fibula-free flap in extremities with 100% obstructive vascular disease in the anterior or posterior tibial artery. Preoperative angiography is indicated to select appropriate candidates for fibula-free tissue transfer with 2-vessel lower extremity runoff to avoid potential donor site ischemic complications.
