An aortic dissection is a serious condition in which a tear occurs in the inner layer of the body’s main artery (aorta).
• Aortic Dissection is a potentially potentially life-threatening condition often requiring surgical repair.
• Type B aortic dissections are usually managed by Vascular and Endovascular Surgeons.
• If uncomplicated, medical management with Blood pressure and pain control are adequate.
• In 10% of Type B aortic dissections, complications develop requiring open surgery or endovascular intervention.
• TEVAR (Thoracoabdominal EndoVascular Aneurysm Repair) results in better 30 day mortality and in-hospital mortality than Open surgery.
• Untreated Type B aortic dissections can result in aneurysmal expansion in 30-40% of cases- which can be prevented with timely treatment by Endovascular surgeons.
Dissection there is tear which begins in the ascending aorta and it progresses throughout the vessel. It often extends as far as the arteries in the leg.
Type B
Dissection, The tear is located only in the descending aorta, but it may also extend into the abdomen.
Vascular and Endovascular Surgeons usually manage type B aortic dissections.If uncomplicated (not compromising blood flow to organs), medical management with Blood pressure control and pain control is adequate.
In 10% of Type B aortic dissections, complications develop requiring open surgery or endovascular intervention.
Results: In-hospital and 30 days post-procedure complication rates are better with TEVAR (Thoracoabdominal Endovascular Aneurysm Repair) than open surgery.
Untreated Type B aortic dissections can result in aneurysmal expansion and rupture of blood vessel in 30-40% of cases. This can be prevented with timely treatment by vascular surgeons.
Many acute and chronic complications are caused by Type B dissection if timely treatment is not done. Various complications that are caused by aortic dissection are:
- Aortic rupture can cause extreme blood loss.
- Rapid heart failure due to Aortic valve incompetence.
- Loss of blood from the coronary arteries to the heart muscle causing a heart attack (myocardial infarction).
- Cardiac tamponade: it is caused due to accumulation of blood in the pericardium (the sac that contains the heart). This leads to an inability of the heart to pump blood.
- Interruption of blood flow to the brain may cause a fatal stroke.
Malperfusion syndrome can also happen as a result of aortic dissection. This syndrome is caused due to the flow of blood in the walls of the aorta rather than flowing through the vessel itself. Because of this enough blood is not able to reach its intended destination. This can lead to organ failure and most frequently involved organs are kidneys and intestines. This may result in temporary or permanent kidney failure and intestinal injury, which requires extensive bowel resection.
