Bronchopulmonary sequestration is a congenital abnormality of nonfunctional pulmonary tissue that lacks normal connections with the bronchial tree. The sequestered tissue typically receives the majority of its blood supply from systemic vessels, most often the distal thoracic or upper abdominal aorta. These lesions often are associated with fetal hydrops, polyhydramnios, and persistent masses postnatally. Bronchopulmonary sequestrations are thought to require resection owing to their predisposition for chronic pulmonary infections later in life. However, spontaneous in utero resolution of these lesions can occur. This report describes the real time, color Doppler, and duplex Doppler ultrasonographic investigation of an intrathoracic bronchopulmonary sequestration that resolved spontaneously. Our investigation of this case provides new insight into a possible mechanism for spontaneous regression of bronchopulmonary sequestration.
支气管肺隔离症是一种先天性的无功能肺组织异常，与支气管树缺乏正常连接。隔离的组织通常大部分血液供应来自体循环血管，最常见的是胸段远端或上腹部主动脉。这些病变常与胎儿水肿、羊水过多以及出生后持续存在的肿块有关。由于支气管肺隔离症在生命后期易发生慢性肺部感染，因此通常认为需要进行切除。然而，这些病变在子宫内可自发消退。本报告描述了一例胸腔内支气管肺隔离症自发消退的实时、彩色多普勒和双功多普勒超声检查。我们对该病例的研究为支气管肺隔离症自发消退的可能机制提供了新的见解。
