摘要

目的：

探讨彩色多普勒血流成像(CDFI)对鼻咽癌患者放疗后椎动脉狭窄的诊断价值。

方法：

选取接受放疗并随访2年以上的56例鼻咽癌患者为放疗组，新诊断未治疗的27例鼻咽癌患者为对照组，用CDFI检测患者椎动脉病变。

结果：

放疗组椎动脉狭窄发生率、斑块形成率显著高于对照组(分别为37.5% vs. 11.1%、26.8% vs. 7.4%，

均＜0.05)，其中以放疗组V1段最高。放疗组与对照组V1和V2段平均血管内径、血流参数比较结果如下：血管内径[(2.940.37) mm

(3.760.45) mm

]

、收缩期峰值血流速度(PSV)[(65.910.3) cm/s

. (50.18.4)cm/s

]

、平均流速(Vm)[(34.26.4) cm/s

.(29.66.1) cm/s

]

、搏动指数(PI)(1.690.27 vs. 1.180.21)、阻力指数(RI)(0.710.06

. 0.580.07)，差异均有统计学意义。

结论：

鼻咽癌患者放疗后椎动脉狭窄和斑块形成发生率增高，以V1段最明显。彩超在诊断鼻咽癌放疗后椎动脉狭窄具有重要价值。

Abstract

Objective:

To evaluate the value of color Doppler ultrasound in diagnosis of vertebral artery stenosis in patients with nasopharyngeal carcinoma after radiotherapy.

Methods:

56 patients with nasopharyngeal carcinoma after radiotherapy who were followed up at least 2 years (radiation group) and 27 newly diagnosed patients before radiotherapy (control group) were enrolled in the study. Color Doppler ultrasound was used to examine the vertebral artery lesions.

Results:

The incidence rat

es of vertebral artery stenosis and plaque formation were significantly increased in the radiation group than the control group (37.5%

. 11.1%; 26.8%

. 7.4%)

particularly in the V1 segment of radiation group. There were significant differences in the following parameters in V1 and V2 segments between the radiation group and control group: vascular diameter [(2.940.37) mm vs. (3.760.45) mm

]

; peak systolic velocity (PSV) [(65.910.3) cm/s

. (50.18.4) cm/s

]

; mean velocity (Vm) [(34.26.4) cm/s

. (29.66.1) cm/s

]

; pulsatility index (PI) (1.690.27

. 1.180.21); resistance index (RI) (0.710.06

. 0.580.07).

Conclusion:

The occurrence of vertebral artery stenosis and plaque formation in patients with nasopharyngeal carcinoma after radiotherapy is increased. Color Doppler ultrasound has great value in the diagnosis of vertebral artery stenosis.
