Endovascular Management of Chronic Type B Aortic Dissection.

Acute uncomplicated type B aortic dissection (aTBAD) is often treated non operatively, with medical management primarily focused on blood pressure and heart rate control. After a 3 month period following the initial diagnosis, the dissection is considered chronic. Frequent clinical and imaging follow-up is performed to evaluate for dissection stability, aneurysmal degeneration, and visceral malperfusion, which would represent indication for surgical or endovascular repair.
