An abdominal aortic aneurysm (AAA) is a potentially life-threatening condition caused by a weakened and enlarged section of the aorta, the body’s main artery. If left untreated, an AAA can rupture, leading to internal bleeding and a high risk of death.
Endovascular Aneurysm Repair (EVAR) is a minimally invasive alternative to open surgery that uses a stent-graft to reinforce the weakened artery and prevent rupture. At Vascular Surgery Associates, our leading vascular specialists in Los Angeles and Santa Monica perform advanced EVAR procedures to provide a safer, more effective solution for treating aortic aneurysms.
What is Endovascular Aneurysm Repair (EVAR)?
EVAR is a catheter-based procedure that repairs abdominal aortic aneurysms without the need for open surgery. Instead of making a large incision in the abdomen, a stent-graft (reinforced synthetic tube) is inserted through small incisions in the groin and positioned inside the aneurysm.
This reinforces the weakened aorta, redirects blood flow, and reduces the risk of aneurysm rupture.
How EVAR is Performed
- Small incisions are made in the groin, and a catheter is inserted into the femoral arteries.
- A stent-graft is carefully positioned within the aorta, using real-time imaging for accuracy.
- The stent is expanded and secured, reinforcing the weakened artery walls.
- Blood is rerouted through the stent-graft, reducing pressure on the aneurysm.
- Once confirmed to be in place, the catheter is removed, and the incisions are closed.
This minimally invasive approach significantly reduces recovery time and the risk of complications compared to traditional open aneurysm repair.
Who is a Candidate for EVAR?
Most patients with AAA (abdominal aortic aneurysm) are eligible for EVAR, especially those who:
- Have an aneurysm measuring 5 cm or larger (considered at high risk of rupture)
- Are experiencing symptoms such as abdominal or back pain
- Are at high surgical risk due to age or medical conditions
- Prefer a minimally invasive approach with a shorter recovery time
At Vascular Surgery Associates, over 95% of the aneurysms we evaluate are successfully treated with EVAR, providing patients with a safer and faster recovery option.
Fenestrated EVAR (fEVAR) – An Advanced Option for Complex Aneurysms
For patients with aneurysms that extend near the renal arteries, fenestrated EVAR (fEVAR) is an advanced technique used to preserve blood flow to the kidneys while reinforcing the aortic wall.
- Only available at select medical centers due to its complexity
- Custom-designed stent grafts allow precise treatment of aneurysms near vital arteries
- Offers a life-saving alternative for patients previously considered ineligible for EVAR
At Vascular Surgery Associates, our specialized vascular surgeons offer fEVAR for select patients, ensuring expert care for even the most complex aortic aneurysms.
Benefits of EVAR Over Traditional Open Surgery
Compared to open aortic aneurysm repair, EVAR offers:
Minimally invasive approach
Small groin incisions instead of a large abdominal incision
Lower risk of complications
Reduced bleeding, infection, and recovery time
Shorter hospital stay
Most patients go home the next day
Faster recovery
Patients return to normal activities within 1-2 weeks
Less pain and scarring
Minimal post-procedure discomfort
Reduced mortality rate
Lower risk of life-threatening complications compared to open surgery
Due to its high success rate and lower risk, EVAR has become the preferred treatment for most abdominal aortic aneurysms.
Long-Term Care After EVAR – What to Expect
While EVAR provides immediate protection against aneurysm rupture, long-term monitoring is essential.
- Regular follow-up CT scans ensure the graft remains in place and functions properly.
- 25-30% of patients may require an additional procedure to correct an endoleak (persistent blood flow outside the graft).
- Lifestyle modifications such as quitting smoking, controlling blood pressure, and maintaining a heart-healthy diet can improve vascular health and prevent further complications.
At Vascular Surgery Associates, we provide comprehensive post-procedure care, ensuring patients receive long-term monitoring and follow-up treatments as needed.
Frequently Asked Questions About EVAR
The procedure typically takes 1-2 hours, depending on the complexity of the aneurysm.
No, the procedure is performed under local or general anesthesia, and patients experience minimal discomfort.
Most patients resume light activities within a few days and return to full activity within 1-2 weeks.
The aneurysm will not shrink completely, but the stent-graft reinforces the artery and prevents rupture.
Yes, most insurance plans, including Medicare, cover EVAR if medically necessary. Our team assists with insurance verification and approval.
