What is advised regarding the trial of labor for patients with TTTS?

In cases of Twin-to-Twin Transfusion Syndrome (TTTS), vaginal delivery poses risks due to the potential for complications related to the condition. TTTS involves an imbalance in blood flow between the twins, which can cause significant fetal distress, and an increased risk of adverse outcomes during labor. As a result, managed delivery typically favors a cesarean section to ensure the best possible outcomes for both mother and infants, given the associated dangers of labor.

While monitoring and individual assessments are essential components of managing pregnancies complicated by TTTS, the general consensus is to avoid trial of labor unless the clinical scenario strongly indicates otherwise. This is due to the unpredictability of fetal heart rate responses and the potential for rapidly evolving clinical circumstances during a trial of labor that could jeopardize the health of both the mother and the twins.

Thus, the recommendation against a trial of labor stems from the necessity to prioritize safety over the method of delivery in these high-risk scenarios.
