aortic aneurysm

Thân thiện

A doctor points to an image of an aortic aneurysm on a medical scan.

Definition

Noun: A pathological condition characterized by a localized, abnormal, and permanent dilation or bulging of the aortic wall. This weakening in the wall of the body's main artery (the aorta) creates a risk of rupture, which is a life-threatening medical emergency.

Usage

The term is used in medical contexts to diagnose, describe, and discuss a specific cardiovascular condition. - It is typically modified by adjectives specifying its location (e.g., thoracic aortic aneurysm, abdominal aortic aneurysm). - It functions as a countable noun (e.g., an aneurysm, multiple aneurysms).

Examples

• The patient was diagnosed with an aortic aneurysm during a routine scan.
• Surgery is often recommended to repair a large aortic aneurysm before it ruptures.
• Monitoring the growth rate of a small aortic aneurysm is a common management strategy.

Advanced Usage

• "Dissecting aortic aneurysm": A specific, acute type where a tear in the inner layer of the aorta allows blood to flow between the layers of the wall, forcing them apart.
  • The patient presented with severe chest pain, indicative of a dissecting aortic aneurysm.
• "Ruptured aortic aneurysm": A catastrophic event where the weakened wall tears completely, causing massive internal bleeding.
  • Emergency surgery is the only treatment for a ruptured aortic aneurysm.

Variants and Related Words

• Aneurysm (n.): The general term for an abnormal bulge in the wall of any blood vessel.
• Aortic (adj.): Pertaining to the aorta.
• Aortopathy (n.): Any disease of the aorta.

Synonyms

• Aortic dilatation (though this term may imply a less severe or more diffuse widening).
• There is no precise single-word synonym; it is a specific medical term.

Related Phrases

• Aortic aneurysm repair: The surgical or endovascular procedure to fix the aneurysm.
• Aortic aneurysm screening: Preventive medical testing to detect the condition, often recommended for at-risk populations like older male smokers.

Notes

This is a compound noun where "aortic" specifies the type and location of the "aneurysm." It is a standard, fixed term in medical terminology.
