隔离肺(Pulmonary seguestration,PS)被认为是肺实质中的岛屿,与支气管并不相通,由体循环而不是肺循环供血~([1]),多见于男性胎儿。这种病变一般预后良好,但若合并感染和充血性心力衰竭可致胎儿肺发育不良、胎儿水肿等,则预后较差。随着近些年来产前超声诊断经验的不断累积,已经能够清晰准确地诊断胎儿隔离肺。本文将14例胎儿隔离肺超声 Pulmonary seguestration (PS) is considered an island in the parenchyma of the lung, not connected to the bronchi, and is supplied by the systemic circulation rather than the pulmonary circulation [1], which is more common in male fetuses. The general prognosis of this disease is good, but if the combined infection and congestive heart failure can cause fetal lung dysplasia, fetal edema, the prognosis is poor. With the continuous accumulation of experience in prenatal ultrasound in recent years, fetal isolated lungs have been able to be clearly and accurately diagnosed. This article will be 14 cases of fetal lung ultrasound
