What Is Endovascular Aneurysm Repair?
Endovascular aneurysm repair, commonly called EVAR, is a minimally invasive technique used for selected aortic aneurysms. A stent-graft is delivered through the blood vessels and positioned within the aorta to create a new pathway for blood flow and exclude the aneurysmal segment from direct pressure.
Catheter-Based Repair
Unlike conventional open aneurysm surgery, EVAR uses vascular access and catheter guidance to position the graft.
Excluding the Aneurysm
The graft creates a channel for blood flow while reducing direct blood flow into the aneurysm sac.
Anatomy Matters
The suitability of EVAR depends on the location, size and shape of the aneurysm and the surrounding blood-vessel anatomy.
EVAR for Selected Aortic Aneurysms
Not every aneurysm can be treated with a standard endovascular graft. Detailed imaging is required to determine whether there is adequate anatomy for safe graft placement and sealing.
Abdominal Aortic Aneurysm
EVAR is commonly considered for suitable abdominal aortic aneurysm anatomy when treatment is indicated.
Thoracic Aortic Disease
Selected thoracic aortic aneurysms and other thoracic aortic conditions may be treated with endovascular grafting when appropriate.
Complex Aortic Disease
Some complex aneurysms require specialized endovascular strategies or open surgery depending on the anatomy and vessels involved.
How Aortic Aneurysms Are Assessed Before EVAR
Imaging is an important part of endovascular planning because the graft must fit the patient's individual vascular anatomy.
CT Angiography
Cross-sectional vascular imaging can define the aneurysm, nearby branches and access vessels and helps determine the feasibility of an endovascular approach.
Aneurysm Anatomy
The neck, diameter, length, angulation and relationship to important arterial branches are considered during treatment planning.
Access Vessels
The arteries used to introduce the delivery system are assessed to determine whether the graft can be safely advanced.
Overall Clinical Assessment
Age, symptoms, other medical conditions and procedural risks are considered alongside imaging findings.
How Endovascular Aneurysm Repair Is Performed
The exact technique varies with the type of aneurysm and device used, but the general treatment pathway involves image-guided catheter access and graft deployment.
Vascular Access
Access is obtained through an artery, commonly through the groin or another suitable vascular route.
Catheter Guidance
Imaging is used to guide the catheter and delivery system toward the aneurysmal segment.
Stent-Graft Deployment
The graft is positioned and expanded so that it lines the affected section of the aorta and provides a new flow channel.
Completion Imaging
Imaging is used to assess graft position, blood flow and whether there is any residual flow around the graft requiring attention.
Endovascular Repair and Open Aneurysm Surgery
Endovascular Repair
- Uses catheter-based vascular access.
- Uses a stent-graft placed inside the aorta.
- Generally involves smaller access wounds.
- Recovery can be shorter for appropriately selected patients.
- Requires ongoing imaging surveillance after treatment.
Open Aneurysm Repair
- Uses a larger surgical incision.
- The aneurysmal segment is directly exposed and repaired.
- A synthetic graft may be used to replace the diseased segment.
- Recovery is generally longer because of the more extensive operation.
- May be required when endovascular anatomy is unsuitable.
What Happens After EVAR?
Recovery depends on the procedure, aneurysm complexity and the patient's overall condition. Follow-up is an important part of endovascular aneurysm care.
Hospital Monitoring
Patients are monitored after the procedure for access-site problems, circulation and other early complications.
Gradual Activity
Activity is increased according to the treating team's instructions and the patient's recovery.
Imaging Surveillance
Follow-up imaging may be required to monitor graft position, blood flow and the aneurysm sac over time.
Possible Complications of EVAR
Access-Site Problems
Bleeding, bruising or other complications can occur at the artery used for catheter access.
Endoleak
Blood can sometimes continue to flow into the aneurysm sac around or through the graft. Follow-up imaging helps detect this complication.
Graft Migration or Blockage
A graft can move, narrow or become blocked, potentially requiring additional treatment.
Infection
Infection is an uncommon but important potential complication of vascular procedures and grafts.
Kidney or Contrast-Related Issues
Contrast imaging and the procedure itself may require special consideration in patients with kidney disease or other risk factors.
Need for Additional Treatment
Some patients may require a secondary endovascular procedure or another intervention during long-term follow-up.

What is endovascular aneurysm repair (EVAR)?
EVAR is a minimally invasive procedure in which a stent-graft is delivered through a blood vessel and positioned inside the affected section of the aorta to help exclude an aneurysm from normal blood flow.
Who may be suitable for EVAR?
Suitability depends on the aneurysm's location, size, shape, vessel anatomy and the patient's overall clinical condition. Imaging is required before deciding whether EVAR is appropriate.
Is EVAR less invasive than open aneurysm surgery?
EVAR generally uses catheter access through blood vessels rather than a large abdominal or chest incision. The appropriate approach depends on individual anatomy and clinical factors.
How is EVAR performed?
A catheter is introduced through an access artery, the stent-graft is guided to the aneurysm under imaging, and the graft is deployed to create a new channel for blood flow.
How long is recovery after EVAR?
Recovery varies according to the procedure and the patient's condition. Endovascular repair generally involves a shorter recovery than open repair, but follow-up remains important.
What are possible complications of EVAR?
Possible complications include access-site problems, infection, graft migration or blockage, and leakage around the graft. Individual risks depend on the procedure and patient.
Is follow-up required after EVAR?
Yes. Endovascular grafts require ongoing clinical and imaging surveillance to check graft position, blood flow and the aneurysm sac.
Can every aortic aneurysm be treated with EVAR?
No. Some aneurysms do not have anatomy suitable for standard endovascular repair and may require another endovascular technique or open surgery.
