[Isolated hydrothorax of a fetus--description of the clinical situation]. / Izolowany hydrothorax plodu --opis sytuacj klinicznej.

A diagnostic procedure in the medical treatment of middle hydrothorax at haemodynamically efficient fetus has been presented in the research. Container of the liquid in the fetal thorax has been observed since the eleventh week of pregnancy. Infection by TORCH viruses has been excluded and typical 46,XX female karyotype has been found in the cytogenic test. A liquid in the pericardial sack (without any sings of the fetal heart defect) was observed in the ECHO examination from 23 to 37 week of pregnancy. Cesarean section was made after 37 weeks of pregnancy and the new-born baby was found to be in good condition, with body mass of 3130g and 9 points in the Apgar scale. The child cardiologist did not diagnose any heart disorders. Awaiting attitude, while monitoring the state of the fetus, seems to be the right course of action in cases of haemodynamically efficient fetus with isolated hydrothorax.
