3339: Sclerotherapy on fetus lung cyst under ultrasonic guidance: A case report

Abstract

A 33-year old pregnant woman at 36 weeks was under ultrasonic inspection, which showed a 3.5 cm × 4 cm cyst in left thoracic cavity of the fetus with thick wall, which compressed mediastinum and heart obviously. On demand of woman, under ultrasonic guidance, we performed sclerotherapy of the cyst with a 22G trocar pricked into the cyst through the fetal thoracic cavity. After aspiration of 10 ml clear fluid, we injected 3 ml 5% sodium morrhuate into the cyst. After treatment, the cyst disappeared and no side effect was found with the woman and fetus. The baby chest X-ray was normal at birth and at every 1/2 year follow-up until 3 years. For fetal lung tissue, there was no risk of pneumothorax, and sodium morrhuate induced aseptic inflammation contributed to the cystic closure. Although fetus floating in amniotic fluid, this procedure could be successful with quick puncture under sonographic guidance.
