Abstract:
Objective To describe the diagnostic approach and clinical outcomes of fetal intraabdominal extralobar pulmonary sequestration (IEPS).Methods Three cases of IEPS were diagnosed prenatally by ultrasound in our center.The data of these 3 cases and 43 cases in prior studies from 1986 to 2016 were retrospectively reviewed.The prenatal sonographic features,treatment,and outcomes were collected.Results The gestational age of diagnosis IEPS was (24.5±5.9)weeks,the male-to-female ratio was 3-4∶1,78.3% (36/46) of IEPS masses located on the left side,47.8% (22/46) of lesions were homogenous and hyperechoic,8.7% (4/46) of cases associated anomalies,78.3% (36/46) of patients were preformed resection and postoperative recovery and subsequent course were uncomplicated.Feeding arteries were detected in 15.2% (7/46) cases and confirmed by surgery or autopsy.Conclusions Prenatal ultrasound has the diagnostic accuracy of IEPS.Feeding arteries noted on color Doppler are strongly indicators of IEPS.Postsurgical outcomes are favorable.
