Aortic Dissection: Causes, Symptoms & Treatments
Aortic dissection is a tear in the inner layer of a weakened area of your aorta that can cause sudden death if not recognized and treated quickly. Aortic dissection can be treated with a variety of surgeries and medications.
Are there different types of aortic dissection?
Aortic tears are divided into two types: type A, which occurs closer to the heart and is potentially fatal, and type B, which occurs further down the aorta and necessitates surgery to repair or replace the first segment. The DeBakey Classification divides dissection into three types.
Does pain from aortic dissection come and go?
Severe pain in the chest, back, or abdomen that is described as ripping, tearing, sharp, or stabbing. Significant chest pain persists despite normal ECG and troponin levels. Symptoms migrate, radiate, or come and go over time.
How do you check for an aortic dissection?
A CT of the chest is used to diagnose an aortic dissection, possibly with the help of an injected contrast liquid, which makes the heart, aorta, and other blood vessels more visible on the CT images.
What is the survival rate of an aortic dissection?
Previous studies have reported survival rates ranging from 52% to 94% at 1 year and 45% to 88% at 5 years after acute type A aortic dissection (TA-AAD).
Can you survive aortic dissection?
Aortic dissection is a life-threatening condition that can be treated with surgery if caught early enough before the aorta ruptures. Only about half of those who have a ruptured aorta survive, and those who do will require lifelong treatment for high blood pressure.
When should you suspect aortic dissection?
Take-Home Points Aortic dissection should be thought of as a torso-wide subarachnoid hemorrhage. Migrating pain, colicky pain, and the need for IV opioids should all raise your suspicion. Intermittent pain can still be a dissection.
How often is aortic dissection missed?
Clinical Presentation Aortic dissection is notoriously difficult to diagnose, with studies showing that up to 38% of patients with AD go undiagnosed at first.
Can you have aortic dissection and not know it?
Aortic dissection without pain has long been thought to be uncommon, but new evidence suggests that symptoms in patients with aortic dissection are more varied than previously thought, and that the classic findings of sudden onset of tearing chest, back, or abdominal pain are frequently absent.
Can emotional stress cause aortic dissection?
u201cOver time, the aorta degenerates and becomes more dilated, increasing stress on the aortic wall,u201d Elefteriades explained. u201cSevere physical or emotional stress raises blood pressure to the point where the tensile limit of the aortic tissue is overwhelmed, resulting in rupture.u201d
Can a dissected aorta heal itself?
Aortic dissection can heal on its own or cause a rupture in the aortic wall, which, depending on its size, can kill someone instantly or within a few days.
How common is aortic dissection?
Aortic dissection is a medical emergency that can quickly become fatal if blood breaks through the aorta’s outer lining. Aortic dissection is uncommon, affecting only 5 to 30 people out of every million people each year. It is most common in older men.
What is a Type A and Type B aortic dissection?
If an aortic dissection occurs in the ascending portion of the aorta, it is classified as Type A, and if it occurs in the descending portion of the aorta, it is classified as Type B.
Does aortic dissection run in families?
A genetic predisposition to thoracic aortic aneurysm and dissection affects about 20% of people with the condition, which means it runs in the family.
How painful is aortic dissection?
Typical signs and symptoms of an aortic dissection include: Sudden severe chest or upper back pain, often described as a tearing, ripping, or shearing sensation that radiates to the neck or down the back; Sudden severe chest or upper back pain, often described as a tearing, ripping, or shearing sensation that radiates to the neck or down the back; Sudden severe chest or upper back pain, often described as a tearing, ripping, or shearing
Who is at risk for aortic dissection?
Aortic dissections most commonly affect men between the ages of 60 and 80, and men are twice as likely as women to have one. Other factors that increase the risk of an aortic dissection include atherosclerosis, or hardening of the arteries.
How do they fix an aortic dissection?
An open-heart surgery is a procedure in which the patient’s heart is cut open.
- A heart bypass machine will take over pumping blood around your heart and lungs once your surgeon has found the tear.
- Manmade (synthetic) grafts can replace the damaged parts of the aorta once your surgeon has found the tear.
