What are possible complications of an endovascular aneurysm repair (EVAR)?

Endovascular aneurysm repair (EVAR) is a minimally invasive (without a large abdominal incision) procedure performed to repair an abdominal aortic aneurysm -- a bulging, weakened area in the wall of the aorta (the largest artery in the body). As with any surgical procedure, complications can occur in an EVAR procedure. Some possible complications may include, but are not limited to, the following:
  • Damage to surrounding blood vessels, organs, or other structures by instruments
  • Kidney damage
  • Limb ischemia (loss of blood flow to legs/feet) from clots
  • Groin wound infection
  • Groin hematoma (large blood-filled bruise)
  • Bleeding
  • Endoleak (continual leaking of blood out of the graft and into the aneurysm sac with potential rupture)
  • Spinal cord injury
Patients who are allergic to or sensitive to medications, contrast dyes, iodine, or latex should notify their physician.

There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to the procedure.
Potential complications for endovascular aneurysm repair (EVAR, also called "stent grafting") include:
  • infection
  • problems such as blood leaking around the stent, movement of the stent, or stent fracture -- these will require another procedure
  • blocked blood flow through the stent
  • a burst artery
  • injury to the kidney
  • death (very rare)

Aneurysms form balloons in weakened arteries of our bodies, potentially causing life-threatening problems such as a stroke. Although aneurysms can form in any weakened artery, they commonly occur in the arteries of the brain and i...

n the aorta, the central artery that extends from your heart through the center of your abdomen and chest. Certain medical conditions, such as high blood pressure, can weaken the arteries, which deliver oxygenated blood from our heart to the rest of our bodies. The pressure of blood traveling through the arteries can lead to this balloon-like bulge. You can have an aneurysm for years without symptoms or problems. Others can have an aneurysm that pops, which can lead to a stroke if bleeding occurs in the brain. Ruptured aneurysms must be treated quickly, usually within minutes, or it can become deadly: about 50% of all ruptured aneurysms are fatal.
