术中颈内动脉转流在颈动脉体瘤切除中的应用

目的 总结颈动脉体瘤(carotid body tumor,CBT)的临床特点,诊断和外科治疗体会,以及术中颈内动脉转流在切除复杂颈动脉体瘤中的应用及效果.方法 回顾性分析1991年1月至2008年12月30例颈动脉体瘤的外科治疗,其中4例患者采用术中颈内动脉转流的临床资料.患者平均年龄(39.2±2.3)岁,男10例,女20例.左侧15例,右侧14例,双侧1例,平均直径(4.9±0.3)cm.术前经彩超、CT、MRI、CTA等明确诊断.手术方式采用单纯颈动脉体瘤切除16例,颈动脉体瘤切除加颈外动脉结扎10例,颈动脉体瘤切除加术中颈内动脉转流自体大隐静脉血管重建4例.结果 30例手术顺利成功,术后经病理检查结果证实均为颈动脉体瘤,4例患者存在血管壁包膜侵犯.术后并发症:声嘶15例,呛咳11例,舌歪17例,面部麻木2例,呼吸困难1例,吞咽困难3例.4例术中行颈内动脉转流下顺利切除瘤体,术后无脑梗塞.全部病例术后无死亡.结论 颈动脉体瘤首选的治疗方式是外科切除.复杂Shamblin Ⅲ型CBT术中必要时采用颈内动脉转流下切除瘤体是一种安全,有效的治疗手段.

Intraoperative internal carotid artery shunt in the resection of carotid body tumors (CBT)

Objective To summarize the experience of surgical management of carotid tumors ( CBT ) and application of shunt between common and internal carotid artery intraoperatively. Methods Thirty patients of CBT (mean age:39. 2 ±2. 3 years old,10 male and 20 female, 15 in left, 14 in right and 1 in both sides) who underwent surgical resection, were retrospectively reviewed. The average size of CBT was 4.9 ±0.3 cm. The diagnosis was established by ultrasound, CT, MRI or carotid arteriography. 16 patients underwent surgical resection of CBT, 10 patients underwent additional ligation of external carotid artery, and 4 patients underwent additional intraoperative shunt between common and internal carotid artery. Results Surgical procedures were successfully performeded in all 30 patients with CBT. Intraoperative shunts were successfully used between common and internal carotid artery in 4 patients. The postoperative complications included hoarseness (15) , bucking (11), crooked tongue ( 17) , dyspnea (1), dysphagia(3). There was no hemiplegia and death. Conclusion Surgical resection is the choice of treatment of carotid body tumor. The application of intraoperative shunt between common and internal carotid artery in complicated Shamblin Ⅲ stage is safe and effective.
