How is type B aortic dissection typically managed?

Type B aortic dissection involves a tear in the aorta that occurs distal to the subclavian artery, which is different from type A dissections that require surgical intervention due to their involvement of the ascending aorta. The management of type B aortic dissection is primarily medical. The main goal is to control blood pressure and reduce the heart rate to decrease the shear stress on the aorta and prevent further tearing.

Medications such as beta-blockers are commonly used to manage blood pressure levels effectively. This approach aims to stabilize the patient and minimize the risk of complications like rupture or progression of the dissection. In cases where there are complications or if the dissection is complicated by other factors, more aggressive surgical or endovascular interventions might become necessary. Nonetheless, the standard initial management of uncomplicated type B aortic dissection is conservative, focusing on meticulous monitoring and control of blood pressure.
