Study design
We retrospectively reviewed medical records from five pregnant women
with complicated TBAD admitted to Zhongnan Hospital of Wuhan University
from Jan 2022 to Jun 2023. Stanford classification was adopted in the
study, and TBAD refers to the absence of involvement of the ascending
aorta. Complicated TBAD is defined as the presence of malperfusion
syndrome or rupture. Diagnosis of complicated TBAD was based on clinical
features and CT angiography (CTA) according to the Society of Thoracic
Surgeons/American Association for thoracic surgery clinical practice
guidelines on the management of TBAD6. This study was
reviewed and approved by the Medical Ethical Committee of Zhongnan
Hospital of Wuhan University (approval number 2023216K). Obtaining
patient consent was not required according to the committee’s
procedures.
