Summary
Selective termination is a second-trimester procedure for anomalous twins in discordant pregnancies. Management protocols, risks, and ethical considerations have evolved significantly over two decades.
Area of Science:
- Perinatology
- Maternal-Fetal Medicine
- Reproductive Genetics
Background:
- Selective termination is a management option for twin pregnancies with one anomalous fetus.
- Diagnosis of discordant twins for congenital anomalies typically occurs in the second trimester.
Purpose of the Study:
- To review the evolution of selective termination procedures in discordant twin pregnancies.
- To discuss current management protocols, risks, and ethical considerations.
Main Methods:
- Review of existing literature and clinical practices regarding selective termination.
- Analysis of diagnostic techniques and procedural outcomes.
Main Results:
- Selective termination is predominantly a second-trimester procedure.
- Management protocols, including indications and timing, have undergone significant changes.
- Ethical debates surrounding selective termination continue to evolve.
Conclusions:
- Selective termination remains a complex management option for discordant twin pregnancies.
- Ongoing evolution of protocols and ethical discourse are critical for clinical practice.
