1. SCOPE & POSITIONING

Etiology / Classification

Postpartum Aortic Dissection (PPAD) is a life-threatening vascular emergency characterized by disruption of the aortic intima allowing blood to enter the medial layer of the vessel wall, creating a false lumen and separating the layers of the aorta.

The postpartum period represents one of the highest-risk windows for pregnancy-associated aortic catastrophe due to:

Hemodynamic overload
Hormonal vascular remodeling
Connective tissue weakening
Hypertensive complications
Genetic aortopathies

15. SCF LAYMAN’S SUMMARY

Postpartum Aortic Dissection is a rare but extremely dangerous condition where the wall of the body’s main artery (the aorta) tears after childbirth. Blood enters the wall of the artery and separates its layers, creating a life-threatening emergency.

According to the SCF model, the condition develops when pregnancy-related changes weaken the aortic wall while increased blood flow and pressure place extraordinary stress on the vessel. In some women, inherited connective tissue disorders or high blood pressure further increase risk.

Symptoms usually appear suddenly and may include:

Severe tearing chest pain
Severe back pain
Fainting
Stroke symptoms
Shortness of breath

Without rapid diagnosis and treatment, the condition can lead to organ failure, aortic rupture, and death.
