Understanding factors impacting successful salvage of a compromised free flap.
Multi-institutional review of free flap reconstructions for head and neck defects (n = 1764).
Free flap compromise rate: 9% (n = 162); 46% salvaged (n = 74). Higher salvage rates in initial 48 hours (64%) vs after (30%; P < .001). Greater compromise (14%) and failure (8%) if inset challenging vs straightforward (6% compromise, 4% failure; P = .035). Greater compromise (23%) and failure (17%) following intraoperative anastomosis revision vs no revision (7% compromise, 4% failure; P < .0001). Success following arterial insufficiency was lower (60% failed, 40% salvaged) vs venous congestion (23% failed, 77% salvaged) (P < .0001). Greater flap salvage following thrombectomy (66%) vs no thrombectomy (34%; P < .0001). Greater flap salvage if operative duration ≤8 hours (57%), vs >8 hours (40%) (P = .04).
There were higher rates of free flap salvage if the vascular compromise occurred within 48 hours, if due to venous congestion, if operative duration ≤8 hours, and if the anastomosis did not require intraoperative revision.
了解影响挽救受损游离皮瓣成功的因素。
对多机构的头颈部缺损游离皮瓣重建术进行回顾(n = 1764)。
游离皮瓣受损率:9%(n = 162);46%得以挽救(n = 74)。最初48小时内的挽救率更高(64%),而之后的挽救率为30%(P < 0.001)。与简单植入相比,植入困难时的受损率更高(14%)且失败率更高(8%)(简单植入时的受损率为6%,失败率为4%;P = 0.035)。术中吻合口修复后的受损率更高(23%)且失败率更高(17%),而未进行修复时的受损率为7%,失败率为4%(P < 0.0001)。动脉供血不足后的成功率较低(60%失败,40%挽救),而静脉淤血后的成功率为(23%失败,77%挽救)(P < 0.0001)。取栓后的皮瓣挽救率更高(66%),而未取栓时的挽救率为34%(P < 0.0001)。手术时长≤8小时时的皮瓣挽救率更高(57%),而手术时长>8小时时的挽救率为40%(P = 0.04)。
如果血管受损发生在48小时内、因静脉淤血导致、手术时长≤8小时且吻合口无需术中修复,则游离皮瓣的挽救率更高。
