What are the best treatments for Aortic Dissection?

Aortic dissection is a life-threatening medical emergency requiring immediate stabilization, typically involving urgent surgical repair or endovascular intervention to prevent rupture of the aortic wall. Treatment for aortic dissection is highly personalized based on the location of the tear (Stanford Type A or Type B) and the patient’s overall clinical stability.

What are the primary medical and surgical treatments for aortic dissection?

The management of aortic dissection is divided into two distinct strategies: emergency surgical intervention and intensive medical therapy. For Type A dissections, which involve the ascending aorta, open-heart surgery is the standard of care to replace the damaged segment of the vessel. For Type B dissections, which involve the descending aorta, treatment often centers on "anti-impulse therapy" to lower blood pressure and heart rate, sometimes supplemented by thoracic endovascular aortic repair (TEVAR), a minimally invasive procedure where a stent-graft is placed inside the aorta.

Which medications are commonly used to stabilize aortic dissection?

Before, during, and after surgical procedures, pharmacological management of aortic dissection focuses on reducing the shear stress on the aortic wall. This is achieved by lowering both the blood pressure and the velocity of blood ejection from the heart. Common medication classes include:

• Beta-blockers: Such as esmolol (Brevibloc) or labetalol (Trandate), used to lower heart rate and blood pressure.


• Vasodilators: Such as nitroprusside (Nitropress), used to rapidly decrease systemic blood pressure if heart rate control alone is insufficient.


• Calcium channel blockers: Used in patients who cannot tolerate beta-blockers to manage hypertension.

What is the multidisciplinary approach to managing aortic dissection?

Because aortic dissection affects the circulatory, muscular, and respiratory systems, a comprehensive care team is essential for long-term survival and recovery. Patients should be monitored by a multidisciplinary team including:

1. Cardiothoracic Surgeons: To perform the primary repair or ongoing monitoring of the aortic graft.


2. Vascular Specialists: To manage endovascular interventions and peripheral circulation.


3. Cardiologists: To manage long-term blood pressure control and monitor for complications such as aortic regurgitation.


4. Genetic Counselors: Especially if there is a suspected underlying connective tissue disorder like Marfan syndrome or Loeys-Dietz syndrome.


5. Clinical Psychologists: To support patients in navigating the significant emotional trauma often associated with a sudden, life-threatening cardiac event.

How does treatment effectiveness vary between patients?

The prognosis and treatment effectiveness for aortic dissection vary significantly based on the age of the patient, the presence of comorbidities, and the speed of diagnosis. Data from the DiseaseMaps.org community, which includes 716 individuals affected by this condition, highlights that recovery is a highly individual process. Patients with underlying genetic conditions may require more frequent, lifelong imaging surveillance (such as CT or MRI scans) to monitor for new dissections or aneurysms, whereas those with isolated, non-genetic dissections may have different long-term management goals.

Next steps

• Consult with a board-certified cardiothoracic surgeon to discuss your specific imaging results and surgical history.


• Ensure your blood pressure is managed strictly according to your cardiologist’s recommendations; do not skip prescribed doses.


• Join the DiseaseMaps.org community to connect with 716 others who have experienced aortic dissection and share recovery strategies.


• Seek immediate emergency care if you experience sudden, severe chest or back pain, which may indicate a recurrence or complication.
