Medication
For type A dissections, surgical repair is essential because mortality rates approach 50% at 48 hours with expectant therapy alone. For type B dissections, medical management is successful in most patients, although a subset with complications or early dilation may benefit from newer endovascular techniques.
Procedures
There are 2 possible surgery methods for aortic dissection repair. The first is standard open-heart surgery. The second is less-invasive endovascular surgery. This may be advised if you aren’t strong enough for open-heart surgery. It may also be advised if the dissection is in your descending aorta.
Nutrition
Medications, such as beta blockers, may be prescribed to lower heart rate and blood pressure. In some Type B aortic dissection cases, medication alone may be used to treat the dissection initially. Surgery may be able to be delayed for months to years depending on the severity of the tear and extent of dissection.

Beta blockers are often the first treatment for a type B aortic dissection. These medications reduce blood pressure by blocking the effects of the hormone epinephrine, or adrenaline. This relaxes the heart, slowing it down. Less blood leaves the heart, and it leaves with less force. If you can’t tolerate beta blockers because you have another condition, such as diabetes, your doctor …

What is the purpose of dissection of the aorta?
An aortic dissection is a tear (dissection) in the wall of the body’s main artery, the aorta. The aorta sends blood from your heart to the rest of your body. A tear causes blood to get in between the aorta’s 3 layers. This reduces the amount of oxygen and nutrients available for your body’s organs. Aortic dissection is a medical emergency.

Why does the aorta bulge?
Over time, the stress of blood flow between aortic layers can cause the weakened area of the aorta to bulge like a balloon, stretching the aorta into what is called an aneurysm – with the risk for late rupture and associated death. Many patients may require future surgeries to repair late developing aneurysms.
What is the aorta?
Your aorta is the large artery that arises from the left lower chamber of the heart and provides oxygen-rich blood throughout your body. This blood vessel is made up of three layers. In certain circumstances, a tear develops in the inner layer. When this occurs, the aorta then bleeds into itself through the middle layer, ...

Do you need beta blockers for blood pressure?
Patients will require life-long beta blockers to manage blood pressure. Sometimes more than one blood pressure medication may be needed to reach the goal. If patients do not tolerate these medications, other blood pressure drugs will be used.
Antihypertensives
Beta blockers are often the first treatment for a type B aortic dissection. These medications reduce blood pressure by blocking the effects of the hormone epinephrine, or adrenaline. This relaxes the heart, slowing it down. Less blood leaves the heart, and it leaves with less force.
Pain Medications
If controlling blood pressure doesn’t reduce the pain from a dissection, doctors may prescribe a pain medication, such as acetaminophen or a nonsteroidal anti-inflammatory drug.

What is type A dissection?
Patients with type A dissections are treated with immediate surgical correction. This involves transfer to the operating room, where median sternotomy is performed. Profound hypothermia is initiated after the patient is placed on cardiopulmonary bypass. Cardiopulmonary bypass is performed by femoral-femoral cannulation and through the superior vena cava for retrograde cerebral perfusion.

What is carotid artery dissection? A carotid artery dissection is a tear in a layer of the wall of a blood vessel called a carotid artery, one of two such arteries found in the neck. Blood vessel walls normally have three layers, and a tear in any of these can allow blood to flow into the resulting space, causing the vessel to bulge.

What are the different types of aortic dissection?
Aortic dissections are divided into two groups, depending on which part of the aorta is affected: 1 Type A. This involves a tear in the part of the aorta where it exits the heart or a tear in the upper aorta (ascending aorta). The tear may extend into the descending aorta and may extend into the tummy (abdomen). 2 Type B. This involves a tear in the lower aorta only (descending aorta). The tear may also extend into the abdomen but any tear that involves the ascending aorta is called a type A aortic dissection.
What is the name of the blood vessel that tears out from the heart?
An aortic dissection is a rare, serious condition in which the inner layer of the aorta (the biggest blood vessel in the body, coming directly from the heart) tears. Blood then surges through the tear, causing the inner and middle layers of the aorta to separate (dissect).
