摘要

肺发育不全(PA)是一种罕见的发育畸形,发生率约为1 / 10 - 15000。单侧PA常伴有其他先天性异常,而双侧PA是致命的。产前诊断很少见,产后诊断比产前诊断更频繁。这可能是一个困难的挑战,因为它与其他更常见的病理有相似的特征。超声在早期诊断和治疗中起着至关重要的作用。正确产前诊断的超声检查结果包括纵隔移位,实质组织或囊性组织缺失,胸廓体积减小,横膈膜升高,心轴偏离,半胸腔大部分被心脏占据。与左PA相比,右PA的预后较差,可能是由于心脏和大血管异常的频率更高。一个罕见的病例早期产前超声诊断单侧胎儿PA,在妊娠18周,被报道。

Prenatal Ultrasound Diagnosis of Unilateral Pulmonary Agenesis
Abstract Pulmonary agenesis (PA) is a rare developmental malformation, with a frequency of approximately 1 in 10–15,000 pregnancies. Unilateral PA is often associated with other congenital anomalies, whereas bilateral PA is fatal. Prenatal diagnosis is rare and is diagnosed more frequently in the postnatal period than in the prenatal period. Is a challenge that may be difficult as it shares similar features with other more common pathologies. Ultrasound plays a crucial role in early diagnosis and management. Ultrasonographic findings for a correct prenatal diagnosis include mediastinum displacement with the absence of parenchymal or cystic tissue, decreased thoracic volume, an elevated diaphragm, cardiac axis deviation, and a hemithoracic cavity largely occupied by the heart. Cases of right PA have a worse prognosis compared to left PA, probably due to higher frequency of cardiac and great vessel abnormalities. A rare case of early prenatal ultrasound diagnosis of unilateral fetal PA, at 18 weeks of gestation, is reported.

期刊介绍: The Journal of Medical Ultrasound is the peer-reviewed publication of the Asian Federation of Societies for Ultrasound in Medicine and Biology, and the Chinese Taipei Society of Ultrasound in Medicine. Its aim is to promote clinical and scientific research in ultrasonography, and to serve as a channel of communication among sonologists, sonographers, and medical ultrasound physicians in the Asia-Pacific region and wider international community. The Journal invites original contributions relating to the clinical and laboratory investigations and applications of ultrasonography.
