Aortic Aneurysm: Symptoms, Treatment, Diagnosis

What is an Aortic Aneurysm?

The aorta is the largest blood vessel in your body. 主动脉瘤 occur when a weak part of the aorta expands like a balloon, forming a blood-filled sac. Aneurysms often cause no symptoms, but they can be life-threatening if they get too large and rupture, 或破裂.

Symptoms of 主动脉瘤

Most aortic aneurysms cause no symptoms. 在很多情况下, your doctor discovers you have one after ordering a CT scan or ultrasound to check on an unrelated condition. In certain cases, patients may experience some symptoms. 这些包括:

  • 腹部和 背部疼痛
  • 高血压
  • 进食后疼痛
  • 减肥
  • 尿路感染
  • Poor circulation to organs and lower extremities

If an aneurysm has ruptured – 或破裂 – patients may experience any of the following symptoms:

  • Severe and sudden abdominal pain
  • 严重的胸部和背部疼痛
  • Dramatic decrease in blood pressure

主动脉瘤的类型

The type of aortic aneurysm you have depends on where it is located. They can occur anywhere along the aorta, from your heart all the way down to your abdomen, 就在肾脏下面.

  • 腹部动脉瘤 occur in the abdomen, below the arteries to both kidneys 
  • 升主动脉瘤 occur on the aorta as it leaves the heart
  • 拱动脉瘤 occur on the part of the aorta that curves around the chest near where the arteries extend to the head and arms
  • 胸动脉瘤 发生在胸部
  • Thoraco-abdominal aneurysms occur on the thoracic (chest) aorta extending into the abdomen

主动脉瘤的成因

Doctors don’t know what causes aortic aneurysms. In some cases, they believe genetics play a role because aortic aneurysms can run in families. About 20 percent of people diagnosed with an aortic aneurysm also have a parent, sibling or child who has been or will be diagnosed with one. Changes in the activity of certain elements within the aorta are thought to weaken the wall and lead to the formation of an aneurysm. Other risk factors include:

  • 吸烟
  • 高血压
  • Chronic pulmonary disease (COPD)

Expert Diagnosis for Aortic Aneurysm at UCLA

If you have a large aortic aneurysm (bigger than 2 inches), your doctor may be able to detect it during a physical examination. You will need to undergo an imaging test to determine how big it is and exactly where it is located in your body. This information helps your doctor find the best treatment plan for you.

成像测试 used advanced equipment to take pictures of organs, tissues and blood vessels inside your body. To diagnose aneurysms, we use the following tests:

  • 腹部超音波
  • CT scan (computerized tomography)
  • MRI (magnetic resonance imaging)
  • MRA (magnetic resonance angiography)

Find out what to expect with these 成像测试.

先进的治疗 for Aortic Aneurysm at UCLA

If you have a small aortic aneurysm, our doctors may recommend a “watch and wait” approach. But medium and large aneurysms often require immediate treatment to repair them fast before they rupture.

We offer comprehensive options for treating aneurysms, from traditional, 开放手术 to the latest advancements in minimally invasive, 血管内修复. We also offer a procedure that combines these two approaches, called 混合修复. Patients with an aneurysm located along their aorta near where it branches off to the kidneys may be candidates for fenestrated 血管内修复, an innovative surgical approach only performed by surgeons with special training.

The best option for you will depend on a number of factors, such as the size and location of your aneurysm, your overall health and age and, 如果可能的话, 个人偏好.
