目的探讨三维能量多普勒超声在肺隔离症产前诊断中的应用价值方法应用三维能量多普勒超声对8例肺内强回声病变胎儿进行产前筛查，并对50例正常胎儿进行肺血供显像。结果出生后8例肺内病变中，孤立性肺隔离症3例，先天性小囊性腺瘤样畸形4例，先天性大囊性和小囊性混合型腺瘤样畸形1例。产前三维能量多普勒超声显示异常的血液供应在所有情况下的肺隔离症，而在没有其他情况下。在三个被证实为肺隔离症的病例中，1例常规二维超声未能识别供血血管，而在妊娠后期才识别出供血血管。三维能量多普勒超声可用于识别供血血管，从而在存在肺隔离症的情况下建立肺隔离症的诊断。高回声肺病变，允许其与先天性囊性腺瘤样畸形鉴别。版权所有（C）2005 ISUOG.出版社：John Wiley Sons，Ltd
Objective To investigate the contribution of three-dimensional power Doppler ultrasound to the prenatal diagnosis of Pulmonary sequestration.Methods Prenatal three-dimensional power Doppler ultrasound was used to screen for an abnormal pulmonary blood supply in eight fetuses with hyperechogenic lung lesions and to image the pulmonary blood supply in 50 normal controls. A comparison was made with postnatal findings.Results Postnatally the eight pulmonary lesions were found to be an isolated pulmonary sequestration (n = 3), a microcystic congenital adenomatoid malformation (n = 4), and a mixed (macrocystic and microcystic) congenital adenomatoid malformation (n = 1). Prenatal three-dimensional power Doppler ultrasound demonstrated an abnormal blood supply in all cases of pulmonary sequestration and in none of the other cases. Among the three cases that turned out to be pulmonary sequestrations, conventional two-dimensional ultrasound failed to identify the feeding vessel in one case and identified it at a later stage of gestation than did three-dimensional power Doppler in the other two.Conclusion Prenatal three-dimensional power Doppler ultrasound may be useful in identifying the feeding vessel and thus establishing the diagnosis of pulmonary sequestration in the presence of a hyperechogenic pulmonary lesion, allowing its differentiation from congenital cystic adenomatoid malformation.
