显微镜下去血管化技术切除颈动脉体瘤20例临床分析

Clinical analysis of 20 cases with carotid body tumor resected by microscopic devascularization technology

摘要:

目的 探讨颈动脉体瘤(CBT)的特点、诊断、治疗方法及术后并发症。方法 对2016年8月—2022年5月收治的20例CBT患者的临床资料进行分析总结，并探讨CBT的临床特点、诊断、治疗及术后并发症。结果 B超、颈部CT、MRI、DSA检查的诊断率分别为74%、95%、90%和100%。其中，DSA的诊断符合率为100%，是最有效的检查手段。所有患者均采用显微镜下去血管化技术切除CBT,其中19例患者手术完整切除肿瘤；1例患者未完整切除肿瘤，根据术中情况及最后病理结果建议患者辅助放疗，随访2年，患者一般情况可，继续密切随访。结论 B型超声检查可作为CBT的初步筛查方法。颈部CT、MRI和DSA 都是CBT的有效检查方法，显微镜下去血管化技术是手术切除CBT的有效安全切除方法。

Abstract:

Objective To investigate the characteristics, diagnosis, treatment and postoperative complications of carotid body tumor (CBT).Methods Clinical data of 20 patients with CBT admitted to our department from August 2016 to May 2022 were retrospectively analyzed, and the characteristics, diagnosis, treatment and postoperative complications of CBT were studied.Results The diagnostic rates of B-mode ultrasound, neck computed tomography (CT), magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) for CBT were 74%, 95%, 90% and 100% respectively. With the highest diagnostic accuracy, DSA was the most effective examination method for CBT. All the patients underwent surgical treatment by microscopic devascularization technology, including complete tumor resection in 19 cases and incomplete resection combined with radiotherapy according to the intraoperative findings and postoperative pathological results in one without recurrence during two-year follow-up.Conclusions B-mode ultrasound can be used as a preliminary screening method for CBT. Neck CT, MRI and DSA are all effective methods for the examination of CBT, and microscopic devascularization technology is an effective and safe method for the surgical removal of this tumor.
