Interposition vein grafting in head and neck reconstructive microsurgery.
To characterize the role of interposition vein grafts, and to determine whether their use significantly influences the success of free tissue transfers in head and neck cancer reconstruction, we reviewed 191 consecutive cases with defects involving the aero-digestive tract soft tissues (80), the mandible (75), craniofacial resections (25), or cutaneous coverage (11). One hundred twenty patients had received prior loco-regional therapy, including 63 patients with recurrent lesions. Interposition vein grafts were used for the artery (11), vein (3), or both (3) in a total of 17 cases. The overall technical success rate was 93.2 percent (178/191). Cases in which vein grafts were used had a significantly (p < 0.001) lower success rate, 70.6 percent (12/17), than those without vein grafts, 95 percent (166/175). Grafts were most often used in patients who had received prior therapy (13/17). The use of vein grafts was associated with a significantly higher incidence of flap failure in head and neck cancer reconstruction; however, a causal relationship is not suggested.
