In brief
This narrative review and case series evaluates intrafetal vascular laser ablation as treatment for bronchopulmonary sequestration with hydrops. Analysis of 41 cases showed no fetal deaths and 9% complication rate, suggesting VLA is effective for BPS with cardiac compromise when performed around 27 weeks gestation.
Written by the GCMD Library team from the article.
Objective: The objective of this study is to assess the effectiveness and safety of intrafetal vascular laser ablation (VLA) for fetuses with bronchopulmonary sequestration (BPS) with hydrops.
Methods: First, we present 3 cases of fetuses with BPS and hydrops treated by VLA. Second, we aimed to conduct a narrative review to identify all reported cases of fetuses with BPS treated by intrafetal VLA.
Results: The review of the literature identified 41 fetuses treated by VLA for BPS with hydrops. The median gestational age of the VLA was 27+0 weeks' gestation [25+0-31+0] with an associated procedure at the same time in 43% of the cases (pleuroamniotic shunt, thoracentesis, and amniodrainage). A second procedure was required in 25% of cases for residual flow in the feeding vessel. No stillbirth or neonatal death was reported. The complications reported were a fetal thoracic hematoma complicated by fetal anemia and 4 preterm deliveries with a rate of 9%.
Conclusion: VLA of the feeding vessel can be an effective treatment but is not without complications. In cases demonstrating cardiac output failure, intrafetal VLA should be considered as a treatment for BPS.
