Spina bifida remains one of the most challenging congenital conditions affecting the central nervous system. Traditional postnatal repair often leaves patients with significant neurological impairments. Recent advances in fetal surgery have opened new possibilities, particularly through minimally invasive fetoscopic techniques. A recent nonrandomized clinical trial has investigated the feasibility of fetoscopic spina bifida repair using a human umbilical cord meningeal patch.

Twin-to-twin transfusion syndrome (TTTS) is a serious condition that affects identical twins sharing a placenta. It can lead to severe complications for both fetuses if left untreated. One of the most effective treatments is fetoscopic laser photocoagulation, which targets abnormal blood vessel connections in the placenta. Despite its success, rare but severe complications such as delayed vascular crisis with intracerebral hemorrhage and anemia can occur after the procedure.

Preeclampsia remains one of the most serious complications during pregnancy, affecting both maternal and fetal health worldwide. Early identification of women at risk can significantly improve outcomes, yet effective screening methods have been challenging to establish. A pivotal study by Chaemsaithong et al., published in the American Journal of Obstetrics & Gynecology in 2020, sheds new light on first trimester screening and prediction of preeclampsia.

Prenatal screening and diagnostic testing for fetal genetic abnormalities have become essential components of modern obstetric care. These tests help identify the risk or presence of genetic conditions early in pregnancy, allowing expectant parents and healthcare providers to make informed decisions. However, international clinical guidelines vary significantly in their recommendations for screening methods, diagnostic tests, and management strategies. This post explores thes

Preeclampsia remains a significant challenge in maternal health, affecting approximately 5-8% of pregnancies worldwide. This condition can lead to serious complications for both mother and baby if not detected and managed early. One valuable tool in assessing the risk of preeclampsia during late pregnancy is the uterine artery Doppler ultrasound. This non-invasive test provides critical information about blood flow and vascular health in the uterus, helping healthcare provide

Selective fetal reduction in complicated monochorionic diamniotic (MCDA) twin pregnancies presents unique challenges. These pregnancies carry increased risks due to shared placental circulation, which can lead to severe complications such as twin-to-twin transfusion syndrome (TTTS), selective intrauterine growth restriction (sIUGR), or discordant anomalies. Microwave ablation (MWA) has emerged as a promising technique for selective fetal reduction, offering a minimally invasi

Multiple pregnancies, especially triplets, present significant challenges in obstetrics due to increased risks for both the mother and fetuses. When triplets share different placental arrangements, such as dichorionic triamniotic (DCTA) or monochorionic triamniotic (MCTA), managing these pregnancies becomes even more complex. Fetal reduction is often considered to improve outcomes by reducing the number of fetuses, but the strategies and implications vary depending on chorion

Polyhydramnios, a condition characterized by excessive amniotic fluid during pregnancy, poses unique challenges in prenatal care. One concern that has emerged is its association with decreased fetal movements, a key indicator of fetal well-being. Recent retrospective cohort studies provide valuable insights into this relationship, offering guidance for healthcare providers and expectant mothers alike.

Fetal abdominal cysts present a diagnostic challenge during pregnancy, requiring careful evaluation to guide management and counseling. These cystic structures, detected within the fetal abdomen, vary widely in origin, size, and clinical significance. Advances in prenatal ultrasonography have improved early detection, allowing healthcare providers to monitor these cysts closely and plan appropriate postnatal care. This article explores the definition and types of fetal abdomi

Pregnancies following artificial cycle frozen embryo transfer (FET) present unique challenges in monitoring and predicting outcomes. One important tool in this process is uterine artery Doppler ultrasound, which offers valuable insights into uteroplacental blood flow and vascular resistance. This blog post explores key findings from recent research on uterine artery Doppler in pregnancies after artificial cycle FET, highlights the clinical importance of Doppler assessments, d

Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder that affects pregnant women, typically in the third trimester. It causes intense itching and can lead to serious complications for both mother and baby. Women who have experienced ICP often worry about what to expect in future pregnancies.
