[A Case Report of Mirror Syndrome after Fetoscopic Laser Photocoagulation for Twin to Twin Transfusion Syndrome].

Abstract

Mirror syndrome is a rare obstetric condition where a mother "mirrors" the edema of her hydropic fetus and placenta. We present the successful resolution of mirror syndrome following fetoscopic laser photocoag- ulation for twin to twin transfusion syndrome (TTTS). A 36-year-old woman was pregnant with monocho- rionic twins. She was diagnosed with TTTS at the 23rd week of pregnancy and transported to our hospi- tal by ambulance for treatment Her human chorionic gonadotropin serum concentration was 144,437 IU - ml'. Fetoscopic laser photocoagulation was performed under local anesthesia with dexmedetomidine. How- ever, her restlessness disturbed the procedure and conversion to general anesthesia was required, which facilitated successful completion of the surgical proce- dure. Postoperatively, her vital signs were stable, and after 30 min, the saturation decreased to 80%. She was intubated, sedated with propofol, and transported to the intensive care unit A transthoracic ultrasound examination showed no cardiomyopathy. A chest X-ray suggested pulmonary edema. Pulmonary edema disap- peared immediately, and she was extubated after 36 hr. Postoperatively, the twins had a good prognosis. There are several reports of mirror syndrome after fetoscopic laser photocoagulation for TTTS. Recovery from mirror syndrome can improve following the reso- lution of fetal hydrops in TTTS using fetoscopic laser photocoagulation.
