It is associated with an increase in fetal mortality and maternal morbility.

It is caused by deletion of all four α-globin genes leading to a severe deficiency in α-globin and to the production of γ-globin tetramers, resulting in ineffective tissue oxygen delivery. Current preconceptional or prenatal screening policies for this disorder are comprehensive, but not all pregnancies with Hb Bart’s disease can be detected early before hydrops become apparent.

Redha Hasan, ABOG*** Sacrococcygeal Teratoma (SCT) is one of the most common congenital tumors in newborns. The majority of the cases are type I and II; therefore, the diagnosis of SCT is mostly made in prenatal period especially during second-trimester ultrasound. This is the first case reported in Bahrain of a pregnant lady in her 20th week of gestation, carrying a fetus with a rapidly growing tumor in its sacrococcygeal area. The woman developed a rare condition of severe pre-eclampsia, cardiomegaly, bilateral bronchopneumonia and pleural effusion suggestive of maternal mirror syndrome (MS). Early prenatal diagnosis of SCT with early detection of maternal mirror syndrome is extremely challenging.

We report a case of a 32 years old pregnant female at 28 weeks of gestation with hydrops fetalis who presented to our Emergency Department with severe shortness of breath, elevated blood pressure and bilateral lower limb edema. The patient underwent bedside ultrasound, which showed pulmonary edema and bilateral pleural effusions with normal cardiac function.

  • Twin to Twin Transfusion Syndrome
    1529 Review Article on Fetal Surgery Twin to twin transfusion syndrome Jena L. Miller^ The Johns Hopkins Center for Fetal Therapy, Department of Gynecology and Obstetrics, Johns Hopkins University, Baltimore, MD, USA Correspondence to: Jena L. Miller, MD. Assistant Professor, The Johns Hopkins Center for Fetal Therapy, Department of Gynecology and Obstetrics, 600 N Wolfe St, Nelson 228, Baltimore, MD 21287, USA. Email: [email protected]. Abstract: Twin to twin transfusion syndrome (TTTS) is a common complication that typically presents in the second trimester of pregnancy in 10–15% of monochorionic twins due to net transfer of volume and hormonal substances from one twin to the other across vascular anastomoses on the placenta. Without recognition and treatment, TTTS is the greatest contributor to fetal loss prior to viability in 90–100% of advanced cases. Ultrasound diagnosis of monochorionicity is most reliable in the first trimester and sets the monitoring strategy for this type of twins. The diagnosis of TTTS is made by ultrasound with the findings of polyhydramnios due to volume overload and polyuria in one twin and oligohydramnios due to oliguria of the co-twin. Assessment of bladder filling as well as arterial and venous Doppler patterns are required for staging disease severity. Assessment of fetal cardiac function also provides additional insight into the fetal cardiovascular impacts of the disease as well as help identify fetuses that may require postnatal follow up. Fetoscopic laser ablation of the communicating vascular anastomoses between the twins is the standard treatment for TTTS. It aims to cure the condition by interrupting the link between their circulations and making them independent of one another.

The pathogenesis of MS remains unclear and may be misdiagnosed as pre-eclampsia. Case presentation: We report a case series of MS in which fetal therapy (intrauterine blood transfusion and pleuroamniotic shunt) resulted in fetal as well as maternal favourable course with complete resolution of the condition in both mother and fetus.

  • Beating the Odds: a Case Report on the Successful Management of a Non-Immune Hydrops Fetalis Due to Hemoglobin Bart's Disease
    Beating the odds: A case report on the successful management of a non-immune hydrops fetalis due to hemoglobin Bart’s disease* By Maria Jane Ellise S. Javier, MD; Maria Rosario C. Cheng, MD, FPOGS and Marinella Agnes G. Abat, MD, FPOGS Department of Obstetrics and Gynecology, The Medical City ABSTRACT Hemoglobin Bart’s hydrops fetalis, characterized by a deletion of all four α-globin genes is the most severe and lethal form of Thalassemia disease. Mortality rate usually ranges from 60-100% of cases.1-5 Given the poor overall prognosis, most countries resort to pregnancy termination or expectant management as the only options to offer affected pregnancies.5 This paper presents a case of the successful management of a primigravid, diagnosed with hydrops fetalis at 29 4/7 weeks age of gestation. She delivered successfully to a live, preterm, baby boy who was later found out to have hydrops fetalis due to Hemoglobin Bart’s disease, and currently, continues to thrive past eight months of age. This report aims to improve the clinicians’ knowledge regarding the work up and management of pregnant patients diagnosed with hydrops fetalis, and increase the clinician’s awareness on the epidemiology, importance of targeted screening, and diagnosis of Alpha-Thalassemia in Filipino patients.

Initially it was described as maternal edema in response to fetal edema due to Rhesus isoimmunisation. Subsequently it has been found in fetal hydrops due to both immune and non immune causes. The maternal condition is likely to improve after fetal treatment, demise or delivery. One case of mirror syndrome due to non immune hydrops is being presented who recovered completely after delivery. The cause of this syndrome is still not understood probably it is placental hypertrophy resulting in high hCG levels. Both mother and fetus are at risk in this condition.
