INTRODUCTION: Prenatal ultrasound-guided laser coagulation (USLC) for complicated bronchopulmonary sequestrations has been described but a consensus on the procedure and on the following management is still lacking. We present our experience and provide a literature review.
METHODS: Retrospective review of patients treated in our center. Literature review and combined analysis of perinatal data were performed.
RESULTS: Five cases were treated at our center, all presenting with severe hydrothorax. Four met the criteria for fetal hydrops. Four cases underwent postnatal computed tomography (CT) scan: in one case, there was no evidence of persistent bronchopulmonary sequestration. The other three underwent thoracoscopic resection, in two, a viable sequestration was found. Including our series, 57 cases have been reported, with no mortality and a success rate of 94.7%. Mean gestational age (GA) at the procedure was 28 ± 3.4 weeks and mean GA at birth and birth weight (BW) were 38.6 ± 2.3 weeks and 3,276 ± 519.8 g, respectively. In 80.6% of the cases investigated postnatally, a residual mass was found, 50% of cases who showed prenatal arterial flow cessation had a persistent sequestration postnatally, and 26.3% of cases underwent postnatal sequestrectomy. Both patients in our series had pathology examination confirming a viable bronchopulmonary sequestration.
CONCLUSION: Prenatal USLC seems to be a valid option for bronchopulmonary sequestration complicated by severe hydrothorax and/or fetal hydrops. Authors believe that this procedure should aim to reverse fetal distress and allow pregnancy continuation, and it should not be considered a definitive treatment. The currently available data do not support changes of the common postnatal management.
