With rapid progression and extremely high mortality brought by the ruptured aneurysm, abdominal aortic aneurysm is one of the most dangerous diseases in the field of vascular surgery. The incidence of abdominal aortic aneurysms in pregnant women is low. Because of the insidious nature of the disease, it is not easily recognized and can be easily misdiagnosed by obstetricians, which can lead to serious adverse outcomes. In this study, we aim to draw attention to this disease and raise awareness among obstetricians about this disease in pregnant women by retrospectively analyzing a rescue case of ruptured abdominal aortic aneurysm after delivery. By reporting the experience and lessons learned from this case, we aim to improve preoperative diagnosis and treatment rates, reduce missed diagnosis, and improve the prognostic outcome of patients.
