The aim of this study was to determine the incidence of postoperative cerebrovascular accident (CVA) following head and neck free tissue transfer and to identify predictive risk factors. A retrospective audit was performed of patients who underwent head and neck reconstructive surgery at Queen Elizabeth University Hospital between 2009 and 2020. The patient records were analysed to identify those who developed CVA within 30 days after surgery. A total of 1109 patients underwent head and neck free tissue transfer surgery, including 1048 neck dissection procedures. Of these, 78.6% had one or more identified risk factors for perioperative stroke. Five patients (0.45%) developed postoperative CVA. The results showed that CVA correlated to patients with hypercholesterolemia (P = 0.007). This study demonstrates the safety of free tissue transfer. Despite underlying co-morbidities and risk factors, the incidence of CVA is low following surgery and manipulation of the major vasculature of the neck.
本研究旨在确定头颈部游离组织移植术后脑血管意外（CVA）的发生率，并确定预测性危险因素。对 2009 年至 2020 年间在伊丽莎白女王大学医院接受头颈部重建手术的患者进行了回顾性审核。分析患者记录以确定术后 30 天内发生 CVA 的患者。共有 1109 例患者接受了头颈部游离组织移植手术，其中 1048 例行颈部解剖术。这些患者中，78.6%有一个或多个围手术期卒中的确定危险因素。5 名患者（0.45%）发生术后 CVA。结果表明，CVA 与高胆固醇血症患者相关（P=0.007）。本研究证明了游离组织移植的安全性。尽管存在潜在的合并症和危险因素，但颈部主要血管的手术和操作后 CVA 的发生率较低。
