FEVAR

FEVAR (Fenestrated Endovascular Aortic Repair) is an advanced endovascular surgery technique used to treat complex aortic aneurysms. This procedure is particularly beneficial for patients with aneurysms that involve the renal arteries or other vital branches of the aorta.

Procedure

FEVAR involves the use of a specially designed stent graft with fenestrations (small holes) that align with the branches of the aorta. The procedure is performed under fluoroscopy guidance. The stent graft is inserted through a small incision in the femoral artery and navigated to the site of the aneurysm. Once in place, the fenestrations allow blood flow to continue to the vital branches while excluding the aneurysm from the circulation.

Preoperative Planning

Preoperative planning for FEVAR is crucial and involves detailed imaging studies such as CT angiography to map the anatomy of the aorta and its branches. This ensures that the fenestrations in the stent graft are accurately aligned with the arterial branches.

Intraoperative Procedure

During the procedure, the patient is typically under general anesthesia. The stent graft is carefully positioned and deployed within the aorta. The fenestrations are aligned with the branch arteries, and additional stents may be placed to ensure proper blood flow.

Postoperative Care

Postoperative care includes monitoring for complications such as endoleak, renal function assessment, and follow-up imaging to ensure the stent graft is functioning correctly.

Indications

FEVAR is indicated for patients with:

• Juxtarenal aneurysms
• Pararenal aneurysms
• Suprarenal aneurysms
• Complex abdominal aortic aneurysms involving branch vessels

Advantages

The advantages of FEVAR include:

• Minimally invasive approach
• Reduced recovery time compared to open surgery
• Preservation of blood flow to vital organs

Complications

Potential complications of FEVAR include:

• Endoleak
• Stent migration
• Renal impairment
• Infection
