【摘要】 目的　探讨经腹部彩色多普勒超声诊断食管静脉曲张的临床价值。方法　应用经腹部超声和内镜检查了 10 0例门脉高压症食管静脉曲张患者。采用二维超声测量食管壁厚度 ,观察食管粘膜及表面光滑度 ,彩色多普勒评价食管壁血流分布及血流速度。结果　食管静脉曲张时 ,食管壁均增厚 ,轻度 (5 .88± 0 .5 5 )mm ,中度 (6.91± 0 .5 9)mm ,重度 (8.2 3± 1.17)mm ,对照组食管壁厚度为 (4 .2 0± 0 .63 )mm ,上述各组间差别均有显著性意义 (P <0 .0 1)。曲张静脉食管壁表面和 (或 )食管粘膜面不平整 ,彩超扫查食管壁内部常可测及彩色静脉血流信号。本组 10 0例门脉高压症患者超声均显示食管壁有不同程度增厚。结论　经腹超声检查诊断食管静脉曲张有较大的临床价值 ,可作为肝病患者常规检查 ,具有较高的临床实用价值和推广价值更多还原

【Abstract】 Objective To assess the value of transabdominal CDFI diagnosing esophageal varices.Methods One hundred patients with esophageal varices in liver cirrhosis were examed with CDFI and endoscopy.Esophageal wall thickness was measured and the irregularity of the wall surface was documented with two dimensional ultrasound.Blood flow signal in the esophageal wall also was evaluated with color Doppler and pulsed Doppler.Results The value of thickness of esophageal wall was ( 5.88 ± 0.55 )mm in patients with esophageal varices in small size and ( 6.91 ± 0.59 )mm in patients in medium size and ( 8.23 ± 1.17 )mm in patients in large size and ( 4.20 ± 0.63 )mm in patients without esophageal varices.The difference was statistically significant(P< 0.01 ),the irregularity of the wall surface was found only in patients,blood flow signal in esophageal wall was also documented with CDFI.The accurate diagnosing degree of esophageal varices were 76.5% in patients with esophageal varices in small size, 45.0% in patients in medium size and 92.1% in patients in large size.Conclusions Transabdominal two dimensional ultrasound and CDFI can play an important role in screening for esophageal varices and can be used more extensively in clinical practice.更多还原
