门静脉高压患者舌下脉络相关改变的口腔内彩色多普勒超声研究

Investigation on sonographic characteristics of tongue's venation in patients with portal hypertension by using color Doppler Ultrasound intra oral cavity

目的:探讨肝硬化患者门脉高压时舌下脉络(舌下神经伴行静脉)的口腔内超声图像特征。方法:对44例肝硬化门脉高压患者、50例健康者舌下神经伴行静脉,运用腔内探头进行二维彩色多普勒(CDFI)及脉冲多普勒(PW)的超声检查,测量其内径及最大血流速度,并对其结果加以对比。结果:门脉高压组较正常组舌下神经伴行静脉内径明显增宽,血流速度明显减低。结论:口腔内彩色多普勒超声可为肝硬化门脉高压时舌下脉络的观测提供定量指标。

Objective：To discuss the sonographic characteristics of tongue＇s venation in patients with portal hypertension of cirrhosis by using endovaginal transducer in the oral cavity. Methods： Forty four patients with portal hypertension of cirrhosis and fifty normal cases were examined with endovaginal transducer by using color Doppler flowing imaging and pulse Doppler. The diameter and peak systolic velocity （Vmax） of the vein accompanying hypoglossal nerve were measured. And the diameter and Vmax were compared between groups. Results：The diameter of the vein accompanying hypoglossal nerve in patients with portal hypertension of cirrhosis were significantly greater,and Vmax in patients with portal hypertension of cirrhosis was significantly decreased than those normal cases. Conclusion： Color Doppler flowing imaging and pulse Doppler can be used to analyse the characteristics of tongue collateral vessels inspection in patients with portal hypertension of cirrhosis in traditional Chinese medicine.
