胎儿肺隔离症的超声表现分析

Study on ultrasonic imaging of fetal pulmonary sequestration

目的分析胎儿隔离肺的超声表现,探讨超声对其的诊断价值。方法对54例肺隔离症胎儿行常规超声扫查,观察隔离肺的位置、大小、形态、回声、毗邻及血供情况。结果 54例肺隔离症胎儿病灶均位于胸腔且为单侧,其中位于左侧胸腔34例,右侧20例,形态呈三角形、圆形或叶状,肿块呈高回声,直径约90~340 mm;47例彩色多普勒可见源于体循环主动脉的血管进入病灶内。结论超声检查对胎儿肺隔离症的诊断有特异性,具有重要临床价值。

Objective To analyze ultrasonic imaging of fetal pulmonary sequestration,and to explore the ultrasonic diagnostic value.Methods Fifty- four fetus with pulmonary sequestration were performed with conventional fetal system screening,the pulmonary sequestration location,size,shape,echo,adjacent to and blood were analyzed.Results Lesions were located in the chest and unilateral,which located in the left chest in 34 cases,right in 20 cases,and the form of them were triangle,round or leaf,had high echo,the diameter were 90 ~340 mm.Color Doppler showed the blood vessel derived from systemic artery into the lesions in 47 cases.Conclusion Ultrasonography has specific and important clinical value in the diagnosis of fetal pulmonary sequestration.
