Successful tracheal occlusion using ultrathin fetoscopic equipment combined with real-time three-dimensional ultrasound

Abstract

Objective: The most common complication of intrauterine tracheal balloon occlusion is the preterm premature rupture of membranes (PPROM) which increases the rate of neonatal morbidity and mortality. Ultrathin fetoscopy may be a method of reducing the risk of PPROM. Materials and Methods: The operation was performed at the 27th week of gestation after sedation and relaxation of a fetus with bilateral congenital diaphragmatic hernia and with the liver lifted upwards into the thorax. An ultrathin sheath with a 1.2-mm fetoscope was used under real-time 3-D ultrasound guidance. The patient delivered in the 38th week of gestation and did not display PPROM after surgery until delivery. Conclusion: Fetal tracheal occlusion using ultrathin fetoscopic equipment in combination with real-time 3-D ultrasound may reduce the risk of PPROM. Copyright © 2009 S. Karger AG, Basel.
