Definition

Healthy Aortic GraftsAortic graft infections are infections of synthetic material that were placed to repair aneurysms or blockages in the artery. If untreated, these infections can be life-threatening.

Causes

Risk

The main risk factor is the presence of a synthetic graft. These infections occur very rarely.

Symptoms

  • Enlargement of groin wound
  • Drainage from groin wound
  • Fever
  • High white-blood cell count
  • Bloodstream infection
  • Infected wound
  • Abdominal pain
  • Bleeding at the site of the graft repair
  • Gastrointestinal bleeding
diagnosis

Diagnosis

  • Computed Tomography (CT) scan: X-ray slices of the aortic artery are taken to check for changes at the site of the graft that suggest infection.
  • Chest X-ray: Electromagnetic energy produces pictures of structures in the chest, including the arteries, to search for signs of infection.
  • White Blood Cell scans: These scans can help localize sites of infection.
treatment

Treatment

  • Graft replacement: The most common treatment is replacing the infected graft with a new graft.
  • Medication: Along with a graft replacement, patients may also receive medication, such as antibiotics, to treat the infected graft.
