目的探讨彩色多普勒超声(CDFI)联合经颅多普勒(TCD)对鼻咽癌放射性颈动脉狭窄的诊断价值。方法筛选2012年1月~2013年12月本院收治的鼻咽癌患者放疗后出现颈动脉狭窄56例,作为研究对象。所有患者均经过颈动脉DSA造影确诊为颈动脉狭窄。采用CDFI、TCD及CDFI联合TCD三种影像学检查方案进行诊断,比较三种方案诊断的正确率。结果联合检查组诊断颈总动脉狭窄29例,颈内动脉狭窄21例,颈外动脉3例,查因3例,诊断正确率为94.64%,CDFI与TCD的诊断正确率分别为75.00%、66.07%,联合检查组诊断正确率明显高于其他两组(P<0.05)。结论应用颈动脉彩色多普勒超声联合经颅多普勒可对鼻咽癌放疗后颈动脉狭窄进行较准确评价,对动脉损伤情况敏感性较高,可在早期对颈动脉损伤做出提示,具有临床应用及推广价值。
Objective To investigate the diagnostic value of color Doppler ultrasonography (CDFI) combined with transcranial Doppler (TCD) for carotid artery stenosis of nasopharyngeal carcinoma. Methods From January 2012 to December 2013, 56 patients with nasopharyngeal carcinoma who underwent carotid artery stenosis after radiotherapy were screened. All patients were diagnosed with carotid artery stenosis by DSA. Using CDFI, TCD and CDFI combined TCD three imaging examination programs to diagnose, compare the correct rate of diagnosis of the three programs. Results The joint examination group diagnosed 29 cases of common carotid artery stenosis, 21 cases of internal carotid artery stenosis, 3 cases of external carotid artery, and 3 cases of Charn. The diagnostic accuracy rate was 94.64%. The diagnostic accuracy of CDFI and TCD was 75.00% and 66.07, respectively. %, the diagnostic accuracy of the joint inspection group was significantly higher than the other two groups (P <0.05). Conclusion Carotid artery color Doppler ultrasound combined with transcranial Doppler can accurately evaluate carotid artery stenosis after radiotherapy for nasopharyngeal carcinoma. It has higher sensitivity to arterial injury and can prompt early carotid artery injury. Has clinical application and promotion value.
