AORTIC DISSECTION

Aortic dissection is a life-threatening condition where the inner layer of the aorta, the body's main artery, tears, creating a false lumen where blood can flow, potentially disrupting blood supply to vital organs. This can lead to sudden, severe chest or back pain, and without immediate treatment, can cause rupture, stroke, or heart failure.

Key Points:

What it is:

A tear in the aorta's wall, causing blood to flow between the layers.

Why it's dangerous:

Blood can flow through the tear, disrupting normal blood flow and potentially leading to rupture or organ damage.

Symptoms:

Sudden, severe chest or back pain, sometimes described as tearing or ripping, and can radiate to other areas.

Causes:

Weakened aorta wall (potentially inherited or due to high blood pressure), atherosclerosis, or injury.

Types:

Type A: Starts in the ascending aorta (upper aorta), often requiring immediate surgery.

Type B: Starts in the descending aorta (lower aorta), may be managed with medications initially.

Treatment:

Acute Aortic Dissection: Immediate surgery is often necessary, especially for Type A dissections.

Medications: To control blood pressure and heart rate, especially for Type B dissections.

Prevention:

Managing high blood pressure and other risk factors can help prevent the condition.
