11例颈动脉体瘤诊断和手术治疗的回顾性分析

目的：探讨颈动脉体瘤（CBT）的诊断方法和手术疗效的评估。方法：回顾性分析11例CBT患者的临床资料，包括CT和DSA检查结果以及手术和疗效。结果：11例CBT均为Shamblin Ⅰ型和Ⅱ型；颈部CT均提示颈动脉分叉处肿块；DSA能清楚显示一个血管化的实质性肿块及其与周围动脉的关系，术前行超选择性瘤体滋养动脉栓塞可减少术中出血；所有病例均完整切除肿瘤而未结扎颈内、外动脉；经1～5年随访，11例患者均无复发。结论：对颈部包块患者应考虑到CBT的可能；DSA在CBT的诊断和治疗中具有重要意义；早期手术可减少动脉和神经损伤。

Retrospective analysis of the diagnosis and surgical treatment of carotid body tumor

OBJECTIVE: To evaluate the diagnostic methods and the surgical treatment in carotid body tumor (CBT). METHOD: In retrospect of clinical data in 11 cases with CBT including CT, digital subtraction angiography (DSA), operation and its curative effect, the clinical experience in diagnosis and surgical treatment of CBT was summarized. RESULT: All 11 cases were classified as Shamblin I and II type. The cervical CT scan showed a tumorous lesion in the carotid bifurcation. DSA revealed definitely a solid vascular mass and its relation with the surrounding arteries. Preoperatively highselected embolization of the tumor- feeding artery could effectively reduce the intraoperative bleeding. All cases of CBT were resected without any carotid artery ligation. With 1-5 years follow-up, none of the CBT recurred in this 11 cases. CONCLUSION: CBT should be considered in patients with mass in the neck. The utilization of DSA could facilitate the diagnosis and the treatment of the CBT. Operation in the early stage of CBT could reduce the possibility of the injury of the arteries and the nerves.
