Anterior mediastinal tracheostomy (AMT) facilitates resection of stomal recurrences after laryngectomy for carcinoma and tumors involving the cervicothoracic trachea and esophagus. Erosion of the innominate artery has been reported as a frequent major complication of AMT, and routine prophylactic division of the innominate artery with AMT has even been advised. Forty-four patients underwent AMT, 10 as an isolated procedure (for stomal recurrence, laryngeal carcinoma, or benign stenosis after laryngectomy) and 34 with concomitant cervical exenteration (laryngopharyngoesophagectomy) for laryngeal, thyroid, or cervicothoracic esophageal malignancies. Transposition of the remaining tracheal stump beneath and to the right of the innominate artery to eliminate tension on the vessel was carried out in 14 patients (32%). Postoperatively, anastomotic leaks complicated nine of 31 pharyngogastric anastomoses. Iatrogenic hypoparathyroidism occurred in 10 patients. All six hospital deaths (14%) occurred in patients undergoing AMT with cervical exenteration, not isolated AMT. There was only one instance of innominate artery erosion. Survival was related to the pathology for which AMT was performed. Anterior mediastinal tracheostomy is a valuable adjunct in the treatment of select patients with malignancies of the cervicothoracic trachea and esophagus, and with attention to operative detail, innominate artery erosion should rarely, if ever, complicate the operation. Prophylactic division of the innominate artery with AMT is unnecessary.
前纵隔气管造口术(AMT)有助于切除喉癌喉切除术后的造口复发灶以及累及颈胸段气管和食管的肿瘤。无名动脉侵蚀已被报道为AMT常见的主要并发症,甚至有人建议对AMT患者常规预防性切断无名动脉。44例患者接受了AMT,其中10例为单纯手术(用于造口复发、喉癌或喉切除术后良性狭窄),34例因喉、甲状腺或颈胸段食管恶性肿瘤行同期颈部廓清术(喉咽食管切除术)。14例患者(32%)将剩余气管残端移位至无名动脉下方并右侧,以消除血管张力。术后,31例胃咽吻合口中有9例出现吻合口漏。10例患者发生医源性甲状旁腺功能减退。6例医院死亡患者(14%)均为接受颈部廓清术的AMT患者,而非单纯AMT患者。仅发生1例无名动脉侵蚀。生存率与行AMT的病理类型有关。前纵隔气管造口术是治疗颈胸段气管和食管恶性肿瘤特定患者的一项有价值的辅助手段,并且注意手术细节的话,无名动脉侵蚀即使发生,也很少会使手术复杂化。对AMT患者预防性切断无名动脉没有必要。
