Successful early in utero management of fetal hydrothorax in a twin pregnancy.
We present a case of dichorionic diamniotic twin pregnancy in which one of the fetuses was found to have a major pleural effusion at 15 weeks of gestation. A single-needle pleural fluid aspiration was performed at 15 and 16 weeks, but the fluid reaccumulated quickly after each procedure and at 16 weeks, the fetus was found to become progressively hydropic. A shunt was then successfully inserted at 17 weeks, which is the earliest gestation reported so far in the literature for such a procedure to treat isolated hydrothorax. Because we felt that the fetus would be too small for a classical double-pigtail pleuroamniotic shunt, we used a multilength double-pigtail bladder stent (Harrison drain; Cook; Spencer; Indiana; USA) via a 13-gauge echo tip trocar. This shunt could be used for both singleton and twin pregnancies presenting with fetal pleural effusion from as early as 16 to 17 weeks to prevent the development of fetal hydrops and polyhydramnios and subsequent premature delivery. Treatment at this stage of gestation would also minimize the risk of lung hypoplasia, which is the main clinical issue when shunts are inserted after 24 weeks.
