彩色多普勒超声在胎儿隔离肺畸形检测中的应用分析

目的探讨彩色多普勒超声检查在胎儿隔离肺(PS)检测中的临床应用价值。方法应用TOSHA-350型彩色超声诊断仪对16425例胎儿进行系统超声畸形筛查,对筛出的PS胎儿,依次扫查胸腔、腹腔。重点观察异常回声团块的二维超声像图特征,并用CDFI探查病灶的血供来源及内部血流情况,同时注意是否合并其他胎儿结构的异常,随访临床影像或病理检查结果。结果彩色多普勒超声共检出13例PS胎儿,均经活产后影像学检查或引产病理检查证实,PS的发生率为7.91/10000,彩色多普勒超声检查诊断PS的准确率为100%。典型隔离肺超声图像特征是:胎儿胸腔内或腹腔内强回声或稍强回声团块、呈三角形或叶状、内部回声均匀、边界清,供血动脉来自体循环动脉或其分支。结论彩色多普勒超声检查对胎儿PS具有重要的诊断价值,该病特有的声像图特征及由体循环供血的特点有助于与其它肺部疾病诊断及鉴别。

Color Doppler ultrasound in diagnosis and differential diagnosis of fetal pulmonary sequestration

Objective To explore the clinical value of color Doppler ultrasound in the diagnostic and differential of in fetal pulmonary sequestration（PS）.Methods Application TOSHA-350 type ultrasound device,16,425 cases of fetal ultrasound screening system were given to exclude malformations.PS fetuses were detected in order to give the chest and abdomen scan.Results 13 cases of PS were detected by color Doppler ultrasound fetal.The incidence of PS was 7.91/10000.The accurate rate of color Doppler ultrasound diagnosis of PS was 100％.Conclusion Color Doppler ultrasound for fetal PS has important diagnostic value.
