Conclusion
Complicated TBAD in late pregnancy is a rapid onset and severe disease that endangers the lives of both mother and fetus. Pregnant women with increased blood pressure during pregnancy should be on the alert for AD. Once obvious chest pain occurs, CTA should be performed to avoid missed diagnosis and time consumption. The management of these patients requires a multidisciplinary team, but the best course of action remains debatable. Patients treated with TEVAR in this series revealed satisfying short-term and midterm outcomes, providing a promising treatment option for complicated TBAD in late pregnancy. Considering the priority of maternal safety and the relative safety of TEVAR for the fetus, we recommend that TEVAR can be performed before the delivery of newborns. Specifically, for patients in the third trimester, a single-stage delivery combined with thoracic endovascular aortic repair is the preferred approach, and TEVAR should be conducted prior to cesarean section. As for patients in the second trimester, pregnancy can be continued if conditions of the mother and the fetus are comprehensively evaluated and intensely monitored.
