Aortic Aneurysm
An aortic aneurysm is a condition characterized by an abnormal bulge or dilation in the wall of the aorta, the largest artery in the body, which carries blood from the heart to the rest of the body. As the aneurysm grows, it can pose a significant risk of rupture, which can lead to life-threatening internal bleeding. There are several types of aortic aneurysms, depending on their location and shape.
- Abdominal Aortic Aneurysm (AAA): Occurs in the portion of the aorta that passes through the abdomen. It is the most common type of aortic aneurysm and is often detected during routine examinations or imaging studies.
- Thoracic Aortic Aneurysm (TAA): Develops in the section of the aorta that runs through the chest. This type can be more challenging to detect early as symptoms may be subtle or mistaken for other conditions.
- Thoracoabdominal Aortic Aneurysm: Extends from the chest into the abdomen, combining features of both thoracic and abdominal aneurysms.
Symptoms
Aortic aneurysms may not present symptoms, especially in the early stages. When symptoms do occur, they vary depending on the location and size of the aneurysm:
- Abdominal Aortic Aneurysm: Symptoms may include a pulsating feeling near the navel, deep, constant pain in the abdomen or back, and sometimes a noticeable bulge.
- Thoracic Aortic Aneurysm: Symptoms can include chest pain, back pain, difficulty breathing, hoarseness, or a cough that doesn’t go away.
- Ruptured Aneurysm: A sudden, severe pain in the back or abdomen, dizziness, rapid heartbeat, and signs of shock such as pale, clammy skin and fainting.
