Summary
Twin pregnancies face higher fetal mortality risks. Single fetal demise in twins increases complications for the surviving twin, necessitating review of causes and management.
Area of Science:
- Perinatology
- Maternal-Fetal Medicine
- Neonatology
Background:
- Twin pregnancies have a higher risk of fetal mortality than singleton pregnancies.
- Single fetal demise occurs in 3.7–6.8% of twin gestations.
- Complications for the surviving twin include fetal loss, preterm birth, and end-organ damage.
Purpose of the Study:
- To review the etiology of single twin demise.
- To discuss the pathophysiology of injury to the surviving twin.
- To summarize current preventive and secondary management strategies.
Main Methods:
- Literature review of existing studies on twin pregnancies and single fetal demise.
- Synthesis of information on etiological factors.
- Analysis of pathophysiological mechanisms of co-twin injury.
- Evaluation of management strategies.
Main Results:
- Single fetal demise significantly elevates risks for the surviving twin.
- Understanding the causes and injury mechanisms is crucial for management.
- Various preventive and therapeutic strategies exist.
Conclusions:
- Single fetal demise in twin pregnancies is a significant clinical challenge.
- Effective management requires a comprehensive understanding of etiology and pathophysiology.
- Further research into optimal preventive and therapeutic interventions is warranted.

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:27Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:24In Vitro Fertilization
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
