RESUMO

Los avances en los protocolos de vitrificación y los resultados obtenidos tras la transferencia de embriones congelados han dado lugar a una versión distinta de los ciclos estándar de reproducción asistida: los ciclos freeze-all. Independientemente de su uso frente a las indicaciones más comunes (progesterona elevada, riesgo de hiperestimulación, entre otros), este nuevo concepto hoy representa una práctica habitual en muchas clínicas siendo aplicado a todas las pacientes. En este artículo analizaremos los distintos factores que pudieron haber contribuido a este cambio de política y la evidencia científica en relación al tema. Basados en esta evidencia concluiremos si las clínicas deberían cambiar su forma de trabajo pasando de transferencias de embriones frescos a solo transferencia de embriones congelados o si deberíamos mantener el protocolo estándar.


Breakthroughs in vitrification protocols and the results obtained after frozen embryo transfer have resulted in a different version of the assisted reproduction standard cycles: the "freeze-all" cycles. Regardless of their use beyond the usual indications (elevated progesterone, risk of hyperstimulation, among others), this new concept currently represents a common practice in many institutions and is applied to all patients. In this article, we will discuss the various factors that may have contributed to this change in policy and the scientific evidence for this topic. Based on this evidence, we will conclude if clinics should change their way of working from fresh embryo transfers to only transfer frozen embryos, or if we should maintain the standard protocol.

RESUMO

Spontaneous ovarian hyperstimulation syndrome (sOHSS) can occur following hypothyroidism. Ultrasonography facilitates diagnosis and monitoring of this syndrome. We describe complete regression of ovarian changes in two hypothyroid patients with sOHSS after treatment with levothyroxine.

RESUMO

The ovarian hyperstimulation syndrome (OHSS) is a rare but serious complication of ovulation induction therapy with gonadotropin. The pathogenesis of OHSS is unclear, but the proposed mechanisms are the production of vasoactive substances that increase local capillary permeability resulting in shifting of fluid from the intravascular space to the third space. The clinical manifestations varies from ascites, hypovolemia, oliguria, hemoconcentration, thromboembolism, and even death. We have experienced a case of severe OHSS with severe ascites, pleural effusion and bilateral enlarged ovaries associated with spontaneous pregnancy without any ovarian stimulation for ovulation induction.

RESUMO

Ovarian hyperstimulation syndrome (OHSS) is one of the most serious complication of controlled ovarian hyperstimulation (COH) and ovulation induction. High serum estradiol concentration can induce the increase of capillary permeability and fluid shift, and it can results in hypovolemia, hemoconcetration, thromboembolism, oliguria, ascites and even death. This physiologic changes of OHSS and/or pregnancy might induce the deterioration of pituitary function in patients with abnormal pituitary conditions such as low pituitary reserve or tumor. However, all this while, panhypopituitarism or pituitary apoplexy in a pregnant woman with OHSS and/or pituitary adenoma has not been reported. We have experienced a case of panhypopituitarism developed in a pregnant woman with severe OHSS and residual pituitary adenoma. She had residual prolactinoma, despite a transsphenoidal adenoidectomy, and had suffered from uncontrolled hyperprolactinemia (HPRL) and chronic anovulation. Therefore, she had taken ovulation induction for getting a pregnancy and conceived, but, in the conception cycle, she was hospitalized for management of severe OHSS and hyperemesis gravidarum. During the period of hospitalization, abrupt panhypopituitarism was developed unexpectedly. Therefore, we present this case with the brief review of literature.
