How does an aortic dissection cause a stroke?

How does an aortic dissection cause a stroke?

A number of mechanisms may be responsible for the ischemic stroke occurring in patients with aortic dissection, including the extension of the dissection into the common carotid arteries, thromboembolism, or cerebral hypoperfusion [13].

Why does aortic dissection cause neurological problems?

Abstract. Background and Purpose— Aortic dissection typically presents with severe chest or back pain. Neurological symptoms may occur because of occlusion of supplying vessels or general hypotension. Especially in pain-free dissections diagnosis can be difficult and delayed.

Are there warning signs of aortic dissection?

Sudden severe chest or upper back pain, often described as a tearing or ripping sensation, that spreads to the neck or down the back. Sudden severe stomach pain. Loss of consciousness. Shortness of breath.

What are the classic clinical symptoms of aortic dissection?

What are the signs and symptoms of aortic dissection?

• Sudden severe, sharp pain in your chest or upper back; also described as a tearing, stabbing or ripping feeling.
• Shortness of breath.
• Fainting or dizziness.
• Low blood pressure; high suspicion when there’s a 20 mmHg pressure difference between arms.

Can a tear in the aorta cause a stroke?

Stroke is a highly dreaded complication of type A acute aortic dissection (TAAAD). However, little data exist on its incidence and association with prognosis.

Can an aortic aneurysm cause a stroke?

Some aortic aneurysms burst, some don’t. Others force blood flow away from your organs and tissues, causing problems, such as heart attacks, kidney damage, stroke, and even death.

Can aortic dissection cause headache?

Headache as the initial manifestation of aortic dissection was assumed due to either vessel distension or pericarotid plexus ischemia. Aortic dissection has to be considered as a rare differential diagnosis of frontal headache, especially in patients who develop aortic regurgitation or chest pain for the first time.

How does aortic dissection cause Horner’s syndrome?

In Type A dissections, extension into the carotid arteries can cause a Horner’s syndrome (Condon and Rose, 1969), and akin to aortic aneurysm, a compressive recurrent laryngeal nerve palsy can result in hoarseness (Khan et al., 1999).

When should you suspect aortic dissection?

Your doctor may think you have an aortic dissection if you have: Sudden tearing or ripping chest pain. Blood pressure difference between the right and left arms. Widening of the aorta on chest X-ray.
