[Current recommendations for the management of TTTS]

Area of Science:

• Perinatology
• Maternal-Fetal Medicine
• Fetal Surgery

Background:

• Twin-to-twin transfusion syndrome (TTTS) is a serious complication of monochorionic twin pregnancies.
• Early detection and management are crucial for improving fetal outcomes.

Purpose of the Study:

• To present current recommendations for diagnosing and managing TTTS.
• To review ultrasound and Doppler findings indicative of TTTS.
• To discuss available therapeutic interventions.

Main Methods:

• Review of current literature and clinical guidelines.
• Detailed description of ultrasound markers in the first and second trimesters.
• Discussion of Doppler studies and echocardiography.
• Overview of therapeutic options: conservative management, amnioreduction, laser therapy, and fetoreduction.

Main Results:

• Specific ultrasound and Doppler findings are presented for early TTTS detection.
• Monitoring frequency is guided by hemodynamic changes, ranging from weekly to daily.
• Fetoscopic laser coagulation is the preferred treatment for TTTS stages I-IV.
• Conservative management is suitable for stages I and V; amnioreduction is an alternative or adjunct therapy.

Conclusions:

• Accurate diagnosis of TTTS relies on a combination of ultrasound and Doppler assessments.
• Treatment strategies for TTTS should be tailored to disease severity and stage.
• Further research is needed to clarify the long-term neurodevelopmental outcomes associated with different TTTS therapies.
