How is an abdominal aortic aneurysm treated?

What are the examination methods for abdominal aortic aneurysm?

1. Abdominal X-ray.

The diagnosis can be established if there is a typical eggshell calcification shadow.

2. Color Doppler ultrasound.

The diagnosis of abdominal aortic aneurysm is very valuable and has a high accuracy. It can detect thickening of the abdominal aortic lumen, and clearly show the appearance and mural thrombus, which is currently the preferred diagnostic method.

3. CTA.

It is the most commonly used examination method for abdominal aortic aneurysm. Compared with ultrasound examination, it can more clearly show the overall picture of abdominal aortic aneurysm and its relationship with surrounding tissue structures such as renal artery, retroperitoneal spine, retroperitoneal hematoma, etc. The diagnostic accuracy rate is almost 100%.

4.MRA angiography.

Although it can also be used as a diagnostic tool for abdominal aortic aneurysm, it is relatively rarely used, especially the latter, and is mainly used as an evaluation tool for endovascular repair of abdominal aortic aneurysm. MRA examination can be considered for patients with renal insufficiency.

How to treat:

1. Drug treatment.

Measures such as controlling blood pressure, heart rate, blood lipids, and quitting smoking can control the increase in aneurysm diameter to a certain extent.

2. Surgical treatment.

Abdominal aortic aneurysm resection and artificial blood vessel replacement are still the classic surgical procedures for treating this disease. Surgical indications include:

1. Abdominal aortic aneurysm with a diameter greater than or equal to 5.5 cm.

2. The diameter increases by 1 cm every year during follow-up.

3 Abdominal aortic aneurysm is symptomatic.

3. Intracavitary treatment.

Endovascular repair of abdominal aortic aneurysm (EVAR) is a minimally invasive surgical method for abdominal aortic aneurysm. Its surgical indications and contraindications are basically the same as those of open surgery. Its characteristics are small trauma, avoiding the huge trauma and pain caused by traditional surgery, and reducing the incidence and mortality of complications of important organs such as the heart and lungs of patients, especially for some high-risk cases with severe complications who are not expected to tolerate traditional open surgery or severe complications after surgery.
