What is the primary treatment for Stanford A aortic dissection?

Immediate surgical intervention is the primary treatment for Stanford A aortic dissection because this type of dissection involves the ascending aorta and poses a high risk of life-threatening complications, such as aortic rupture or cardiac tamponade. The urgency in addressing this condition stems from the fact that the dissection can quickly lead to severe cardiovascular instability and death.

Surgical options typically include either repairing the aorta or replacing it, depending on the extent of the dissection and the specific anatomy involved. The goal is to quickly stabilize the patient and prevent further deterioration.

Other management strategies, such as medical management with beta-blockers, while important for managing blood pressure and reducing shear stress on the aortic wall, are not sufficient as standalone treatments for Stanford A dissections due to the immediate risk presented. Observation and follow-up are not appropriate given the acute nature of the condition, and endovascular stenting may be more suitable for Stanford B dissections, which do not involve the ascending aorta, making it not feasible for Stanford A cases.
