The management of the poor responder patients is very difficult. Currently, there is no any standard treatment for poor responder patients. Considering the importance of the problem, it is important to identify a diagnostic and therapeutic target. Our review shows that there are many studies with different therapeutic approaches which deserve further in-depth study to standardize diagnostic and therapeutic target.
Introduction: Fetal congenital cystic adenomatoid malformation is a pulmonary developmental anomaly arising from an overgrowth of the terminal respiratory bronchioles. This is such a rare malformation that it is not always thought of as a diagnostic possibility. Case: In the present case, after a large pulmonary cyst started deviating the mediastinum and following an increase in amniotic fluid volume in the fetus at 28 weeks of gestation, the placement of a catheter for continuous drainage was performed. Subsequent follow-up with ultrasounds and serial echocardiograms revealed normalization of the position of mediastinum, normal amniotic fluid levels, and the correct position of the catheter. The size of the cyst was decreasing daily, but 8 weeks after fetal invasive procedure, there was concern about the stabilization of its size, with the suspicion of obstruction of the catheter. Cesarean delivery was performed at 38 weeks’ gestation. The size of the cyst on the day of C-section was 3.0 × 2.9 × 2.1 cm. At delivery, the infant weighed 3,030 g, with no evidence of respiratory distress, revealing the correct location of catheter. At day 4 after delivery a superior right pulmonary lobe resection was performed. Conclusion: Large pulmonary cysts may produce deviation of mediastinum and can lead to cardiac tamponade, nonimmune hydrops and pulmonary hypoplasia. Precise prenatal imaging and different fetal therapeutic strategies may allow survival of affected fetuses.

Rev Bras Ginecol Obstet. 2005; 27(6): Relato de Caso RESUMO A malformação adenomatóide cística fetal consiste em anomalia do desenvolvimento pulmonar, proveniente de crescimento anormal dos bronquíolos respiratórios terminais. Por tratar-se de malformação rara, nem sempre é lembrada como possibilidade diagnóstica. Apresentamos o relato de um caso de malformação adenomatóide cística pulmonar fetal em adolescente primigesta, ressaltando a importância do seu diagnóstico precoce e possibilidades terapêuticas. Apresentamos também o aspecto evidenciado após a colocação de cateter para drenagem contínua. PALAVRAS-CHAVE: Diagnóstico pré-natal; Feto/anormalidades; Malformação adenomatóide cística congênita do pulmãoABSTRACT Fetal cystic adenomatoid malformation is a pulmonary developmental anomaly arising from an overgrowth of the terminal respiratory bronchioles. This is such a rare malformation, that is not always thought of as a diagnostic possibility. We present a case of pulmonary cystic adenomatoid malformation and emphasize the importance of early diagnosis and therapeutic possibilities. We also present its evolution after prenatal placement of a catheter for continuous drainage. IntroduçãoAs alterações císticas envolvendo as estruturas intratorácicas fetais são, em sua maioria, acessíveis à propedêutica ultra-sonográfica durante o período intra-uterino.Na avaliação do tórax fetal normal, os órgãos identificáveis são os pulmões e o coração, entretanto, em face de situações patológicas, estruturas torácicas invisíveis ao exame normal, tais como, espaço pleural, espaço pericárdico e mediastino, são de fundamental importância para se firmar um diagnóstico provável e conduzir apropriadamente cada situação 1 .A malformação adenomatóide cística pulmonar (MACP) é caracterizada por anomalia de desenvolvimento do epitélio bronquiolar endodérmico e seu mesênquima adjacente originando a proliferação excessiva das estruturas respiratórias terminais. Esta falha embrionária ocorre entre a 6ª e a 8ª semana após a concepção, sendo que algumas lesões podem se desenvolver mais tardiamente entre a 14ª e a 18ª semana da gravidez 2 .Diagnóstico e conduta pré-natal em malformação adenomatóide cística pulmonar fetal: apresentação de um caso Prenatal diagnosis and therapy for fetal cystic adenomatoid pulmonary
