What is Treatment of Abdominal and Peripheral Aneurysms?

The treatment of abdominal and peripheral aneurysms typically depends on the size, location, and overall health of the patient. There are two main approaches to treating aneurysms: surveillance and intervention.

Surveillance: For small aneurysms that are not causing symptoms and are not at immediate risk of rupture, a “watchful waiting” approach may be taken. Regular monitoring through imaging tests, such as ultrasound or CT scans, is done to track the size and growth of the aneurysm. Lifestyle modifications, such as quitting smoking and managing blood pressure, may be recommended to reduce the risk of aneurysm growth or rupture.
Intervention: When an aneurysm reaches a certain size or shows signs of rapid growth, intervention may be necessary to prevent rupture. The two main types of interventions are:

a. Endovascular Aneurysm Repair (EVAR): This minimally invasive procedure involves the placement of a stent graft within the aneurysm. A catheter is inserted through a small incision in the groin and guided to the site of the aneurysm. The stent graft is then deployed, creating a new pathway for blood flow and relieving pressure on the weakened vessel wall.

b. Open Surgical Repair: In some cases, open surgery may be required, especially if the anatomy of the aneurysm is not suitable for endovascular repair. During open surgery, a large incision is made in the abdomen or affected area, and the aneurysm is directly repaired by replacing the weakened section of the blood vessel with a synthetic graft.

The choice between EVAR and open surgical repair depends on various factors, including the size, location, and shape of the aneurysm, as well as the patient’s overall health and anatomy.

It is important to note that the treatment of aneurysms is highly individualized, and the best approach should be determined by a vascular surgeon or a multidisciplinary team of specialists based on the specific circumstances of each patient. Regular follow-up care and monitoring are essential to ensure the ongoing health and stability of the repaired or managed aneurysm.
