Ultrasound diagnosis of first trimester umbilical cord entanglement in monochorionic monoamniotic twins - case report and review of the literature.
BMC Pregnancy Childbirth
November 2024
Hadassah University Hospital, Mt Scopus, Obstetrics and Gynecology, Jerusalem, Israel.
Article Synopsis
- * A 32-year-old woman undergoing assisted reproductive technology showed two embryos with regular heartbeats and tightly entangled umbilical cords at 8.5 weeks gestation, identified through various ultrasound techniques.
- * The findings suggest that UCE can be diagnosed as early as eight weeks of gestation, but may indicate a poor prognosis for the pregnancy.
Cord Occlusion in Twin Reversed Arterial Perfusion Sequence: A Retrospective Study of Laser Photocoagulation versus Radiofrequency Ablation.
Fetal Diagn Ther
November 2024
Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, University of Southern California, Los Angeles, California, USA.
Article Synopsis
- Twin reversed arterial perfusion (TRAP) sequence affects identical twins and can be managed with umbilical cord occlusion (UCO) to improve the survival of the healthier twin, known as the "pump twin."
- A study compared the effectiveness of two techniques used in UCO—laser photocoagulation and radiofrequency ablation (RFA)—on the outcomes of high-risk TRAP sequence cases.
- Results showed no significant difference in 30-day neonatal survival rates between the two treatment methods, with survival rates of approximately 91.9% for laser and 89.2% for RFA.
The Spectrum of clinical manifestations in newborns with the COQ4 mutation: case series and literature review.
Front Pediatr
September 2024
Nenoatal Intensive Care Unit, Guangzhou Wowen and Children's Medical Center, Guangzhou Medical University, Guangzhou, China.
Article Synopsis
- - The study examines primary coenzyme Q10 deficiency in neonates with COQ4 mutations to enhance diagnosis and treatment outcomes.
- - It describes four cases, revealing a higher incidence of prenatal issues in preterm infants and highlights that hyperlactatemia was the most common manifestation, found in 75% of the patients.
- - The research indicates a low survival rate associated with COQ4 mutations, as well as limited treatment options, with only a small fraction of patients receiving coenzyme Q10 supplementation.
Prenatal diagnosis of the rarest conjoint twin "diprosopus tetrophthalmus" during anomaly scan: A case report.

Department of Radiology, Tribhuvan University Teaching Hospital, Kathmandu, Nepal.
Twin pregnancy is considered high-risk pregnancy because of its various effects on maternal and fetal physiology. Twin pregnancy can be dizygotic or monozygotic, the latter being less common. Depending upon the period of separation of an embryo, monozygotic twins can share amniotic cavity and placenta with the monochorionic monoamniotic form being the least common type.

Department of Obstetrics and Gynecology, Wyckoff Heights Medical Center, Brooklyn, New York.
Article Synopsis
- - The TRAP (Twin Reversed Arterial Perfusion) sequence occurs in monochorionic pregnancies where one fetus is healthy and the other is non-viable, leading to risks like high-output cardiac failure in the viable twin.
- - A 32-year-old woman with TRAP syndrome experienced contractions and spotting at 26 weeks and underwent a cesarean section after concerns of placental abruption; her viable twin was born but later died due to prematurity complications.
- - This case emphasizes the need for early detection and ongoing prenatal care in managing TRAP syndrome, while also calling for more research into interventions that improve outcomes for affected pregnancies.
