Aortic Dissection ---- A dissecting aortic aneurysm (aortic dissection) occurs when a tear in the intima allows blood to enter the media, creating a false lumen that can propagate along the aortic wall. --- Pathophysiology Initiated by intimal tear → blood dissects into media → separation of layers. The false lumen may re-enter the true lumen or rupture externally (fatal). Weakening of media due to hypertension, cystic medial degeneration, or connective tissue disease (e.g., Marfan, Ehlers–Danlo

Aortic Dissections: Know the Classifications! Aortic dissection = time is life. Recognizing the type helps guide treatment. 🚑 🔹 Stanford Type A – Involves the ascending aorta (with or without descending involvement). Surgical emergency! 🔹 Stanford Type B – Involves only the descending aorta. Usually managed medically unless complications arise. 🔹 DeBakey Type I – Starts in the ascending aorta and extends to the descending aorta. 🔹 DeBakey Type II – Confined to the ascending aorta. 🔹 DeBake
