[FETAL THERAPY: INTRAUTERINE THORACO-AMNIOTIC SHUNTING IN MACROCYSTIC TYPE CYSTIC ADENOMATOID MALFORMATION OF THE LUNG: REVIEW OF THE LITERATURE AND CASE REPORT].

ABSTRACT OBJECTIVE: To present a case of macrocystic type cystic adenomatoid malformation of the lung (CCAM) treated with thoraco-amniotic shunt and to review the published data to evaluate the efficiency of thoraco-amniotic shunts for drainage of (CCAM).

MATERIALS AND METHODS: This wass case reported of a fetus with a large thoracic cyst, major mediastinal shift and polyhidramnion treated with thoraco-amniotic shunting. We identified 8 cases diagnosed with CCAM and only one case met the criteria for fetal surgery. Thoracoamniotic shunting was successfully performed under local anesthesia and ultrasound control with operating time of 35 minutes. Medline was searched to identify cases of CCAM treated by thoraco-amniotic shunting.

RESULTS: Fetal therapy forlung lesion was successfully performed at 30 weeks of gestation with CCAM volume ratio > 1.6 January, 2015 and amniodrenage after the procedure was carried out. The pregnancy has progressed uneventfully and planned Cesarean section was performed at 38 weeks of gestation. The optimal management of such case was performed for the first time in Bulgaria, which required an experienced interdisciplinary team. The newborn underwent resection of the lesion with no growth or neurodevelopment delay. The literature search identified cases with CCAM treated with thoraco-amniotic shunting between 1987 and 2016 and the the survival rate of non-hydropic fetuses that underwent treatment was 88%.

CONCLUSIONS: Thoraco-amniotic shunting for macrocystic type CCAM is associated reduced risk of fetal intrauterine death and is also likely to be beneficial for the following major postnatal surgery
