Endovascular aneurysm repair (EVAR)
Endovascular aneurysm repair (EVAR) is a minimally invasive procedure used to treat abdominal aortic aneurysms (AAAs), which are weakened areas in the aorta that can balloon and potentially rupture. During EVAR, a stent graft is inserted into the aorta through small incisions in the groin, providing support and reinforcing the weakened vessel wall to prevent rupture.
Our Expertise
Our team specializes in EVAR procedures, offering advanced expertise in performing this minimally invasive treatment option for abdominal aortic aneurysms. Led by experienced vascular surgeons and interventional radiologists, we are dedicated to providing individualized care and achieving excellent outcomes for patients with AAAs.
Benefits of EVAR
Enhanced Aneurysm Repair
EVAR reinforces the weakened vessel wall of the abdominal aorta by deploying a stent graft, effectively sealing off the aneurysm and preventing its rupture. This reduces the risk of life-threatening complications and promotes long-term vascular health.
Minimally Invasive Approach
EVAR is a minimally invasive procedure that involves small incisions in the groin area, resulting in shorter recovery times, reduced pain, and lower risk of complications compared to traditional open surgical repair. Patients typically experience faster return to normal activities following EVAR.
Reduced Mortality and Morbidity
Studies have shown that EVAR is associated with lower mortality rates and fewer complications compared to open surgical repair for abdominal aortic aneurysms. This makes it a preferred treatment option for patients, especially those considered high risk for surgery.
The EVAR Procedure
Here's what you can expect during a EVAR procedure:
Preparation
The patient undergoes preoperative assessments and discussions with the medical team to prepare for the EVAR procedure. Anesthesia options, such as general anesthesia or conscious sedation, are chosen based on the patient's health and preferences.
Access
Small incisions are made in the groin area to access the femoral arteries. Alternatively, access may be obtained through small incisions in the arms or wrists.
Guidewire Insertion
Thin guidewires are inserted through the femoral arteries and guided to the site of the abdominal aortic aneurysm under fluoroscopic guidance. These wires serve as pathways for the delivery of the stent graft.
Catheter Placement
Catheters containing the stent graft components are advanced through the femoral arteries and guided to the site of the aneurysm. The stent graft is positioned within the aneurysm and deployed to provide support and reinforcement to the weakened vessel wall.
Stent Graft Deployment
The stent graft is expanded and secured in place, effectively sealing off the aneurysm and restoring normal blood flow through the aorta.
Assessment
The position and function of the stent graft are assessed using fluoroscopy and angiography to ensure proper placement and sealing of the aneurysm.
Closure
Once the stent graft is securely in place, the catheters are removed, and the incision sites are closed using sutures or closure devices.
Recovery
Patients are typically monitored in a recovery area for a short period before being transferred to a regular hospital room. Most patients experience a rapid recovery and can resume normal activities within a few days following the EVAR procedure. Follow-up appointments are scheduled to monitor the effectiveness of the treatment and the patient's overall vascular health.
