Is ascending aorta dilation serious?
The dilated or aneurysmal ascending aorta is at risk for spontaneous rupture or dissection. The magnitude of this risk is closely related to the size of the aorta and the underlying pathology of the aortic wall.
What does aortic dilatation mean?
Otherwise known as an aortic root aneurysm, a dilated aortic root is when the first section of the aorta, where the aortic valve resides, becomes enlarged. When this enlargement reaches a critical size, there is a risk of it rupturing or tearing, leading to a life-threatening situation.
What causes dilatation of aorta?
Progressive dilatation of the aortic root is caused by medial degeneration and destruction of the elastic and collagen fibers and can be also associated with high blood pressure, high stroke volume, and inflammatory diseases [14–17].
What is the treatment for a dilated aorta?
The most common type of surgery is open abdominal or chest repair, where the doctor opens up your chest or abdomen, depending on where the problem is, removes the bulge in your aorta, and replaces it with a fabric tube called a graft.
What does mild dilatation of the ascending aorta mean?
An ascending aortic aneurysm is a weak spot in the top part of your aorta, which is the main artery in your body. The aneurysm bulges outward, and may cause your blood vessel wall to tear or break open. It’s a life-threatening condition.
Does ascending aorta dilated with age?
The AA dilates and stiffens with aging which increases the vessel wall tension, likely predisposing aneurysm and dissection.
Is aortic dilation the same as aortic aneurysm?
Nevertheless, by common convention, aortic dilatation refers to a dimension that is greater than the 95th percentile for the normal person age, sex and body size. In contrast, an aneurysm is defined as a localized dilation of the aorta that is more than 50% of predicted (ratio of observed to expected diameter ≥ 1.5).
Can you live a long life with enlarged aorta?
Yes, you can live with an aortic aneurysm, and there are many ways to prevent dissection (splitting of the blood vessel wall that causes blood to leak) or worse, a rupture (a burst aneurysm). Some aortic aneurysms are hereditary or congenital, such as bicuspid aortic valve, infection or inflammatory conditions.
What is mildly dilated ascending aorta?
A mild to moderately dilated ascending aorta was defined as having an aorta ascendens dimension between 40 mm to 45 mm on the computer tomography.
What happens if the ascending aorta is dilated?
Such dilatation of the ascending aorta frequently leads to significant aortic valvular insufficiency, even in the presence of an otherwise normal valve. The dilated or aneurysmal ascending aorta is at risk for spontaneous rupture or dissection.
How is the diameter of the ascending aorta measured?
The diameter of the ascending aorta should be measured at 4 levels: at the level of the annulus, the aortic sinuses, the sinotubular junction, and the proximal ascending aorta.
What is an aneurysmal aorta dilatation?
A 50% increase over the normal diameter is considered aneurysmal dilatation. Such dilatation of the ascending aorta frequently leads to significant aortic valvular insufficiency, even in the presence of an otherwise normal valve. The dilated or aneurysmal ascending aorta is at risk for spontaneous rupture or dissection.
What are the indications for elective surgery for dilated ascending aorta?
Methods: In recommending elective surgery for the dilated ascending aorta, the patient’s age, the relative size of the aorta, the structure and function of the aortic valve, and the pathology of the aortic wall have to be considered.
