National registry of thoracoamniotic shunting using a double-basket catheter: A post-marketing surveillance registry of 295 patients with fetal hydrothorax.

OBJECTIVE: We report on the 1-year outcomes of fetuses who underwent thoracoamniotic shunting (TAS) with a double-basket catheter for fetal hydrothorax (FHT) using a national post-marketing surveillance registry. METHODS: This surveillance study was conducted for cases enrolled between 2011 and 2019. Preoperative, operative, and postoperative findings and outcomes had to be reported through the national surveillance website. RESULTS: Forty-three institutes enrolled 295 patients. In 60 patients, associated abnormalities were diagnosed after birth. Among the 235 patients with isolated hydrothorax, the survival rate at 1 year of age was 70.5%. Among these patients, 89% did not require oxygen or other respiratory support. The 1-year survival rate in complicated cases was 27%. Trisomy 21 was the most common associated problem (40%). Catheter associated problems, including dislocation (25%), obstruction (24%), and preterm rupture of the membranes (6%) were observed, but there were no severe maternal complications. TAS before 29.5 weeks of gestation (odds ratio [OR] 0.16) and skin edema and ascites (OR 0.06) were risk factors for death at one year, whereas appropriate shunt location for >28 days (OR 4.2) was a protective factor. CONCLUSION: We report a favorable survival rate in fetuses with isolated FHT treated with this double-basket catheter.

Tratamiento extrauterino intraparto: manejo del recién nacido con síndrome de obstrucción congénita de la vía aérea superior: informe de un caso / Ex utero intrapartum treatment: management of neonatal congenital high airway obstruction syndrome: case report

En años recientes, el tratamiento extrauterino intraparto, que consiste en la intubación fetal extrauterina previa al nacimiento, ha adquirido relevancia en la reducción de la morbimortalidad de neonatos afectados por el síndrome de obstrucción congénita de la vía aérea superior. Caso clínico. Presentamos una madre con un feto de 22 semanas de gestación y diagnóstico de estenosis de la vía aérea, que anticipaba déficit ventilatorio fetal extraparto y derivó en la aplicación del tratamiento extrauterino intraparto para garantizar el intercambio gaseoso fetal en el momento del nacimiento. Conclusiones. La práctica oportuna del procedimiento extrauterino intraparto logró en este caso, mediante el control de los factores maternos y fetales que pudieran afectar la circulación feto-placentaria, el nacimiento de un niño cuya evolución inmediata y a largo plazo fue exitosa con desarrollo deuna vida normal.(AU)

In recent years, the ex utero intrapartum treatment (EXIT), that involves extrauterine fetal intubation prior to delivery, has become relevant for the reduction in morbidity and mortality of neonates affected by congenital high airway obstructionsyndrome (CHAOS). Clinical case. We report the case of the mother of an unborn child at pregnancy week 22, who was diagnosed a congenitalpulmonary malformation that precluded intrapartum fetal circulatory deficit and resulted in the conduction of an EXITtechnique, with the aim of ensuring fetal blood gas exchange at the time of delivery. Conclusions. A timely practice of the EXIT technique resulted, by monitoring both maternal and fetal factors that might affect fetoplacental circulation, in the birth of a child whoseimmediate and long-term outcomes were successful allowing the child live a normal life.(AU)
