Background

  • A vasculitis that affects large vessels leading to fibrosis and narrowing of the vessels [1]
  • Most often affects women of Asian descent during reproductive age
  • Diagnosis is often delayed due to the rarity of the disease and varied symptoms
  • The disease process chronically improves and relapses[2]

Clinical Features

  • Hypertension
  • Congestive Heart Failure
  • CVA
  • Dizziness
  • Pulselessness
  • Claudication
  • Bruits
  • Visual Disturbance
  • Arthralgias/Myalgias
  • Aortic Regurgitation
  • Weight Loss
  • Valvular Regurgitation
  • Arterial Aneurysm

Differential Diagnosis

Evaluation

An MRA showing occlusion of the left subclavian artery and significant narrowing of the left common carotid artery
  • Work up should be tailored to the patient's symptoms as this disease process affects multiple organ systems due to vascular damage

Laboratory

  • ESR, CRP, WBC may or may not be elevated
  • Anemia may be present

Imaging

  • Angiography revealing narrowing/occlusion of large vessels (e.g. Aorta) is the gold standard [3]
  • MRA or CTA can be used as well to appreciate vascular stenoses

Management

  • Oral Prednisone 1 mg/kg for the first month followed by a taper
    • Taper to approximately 10 mg/day
  • The addition of Methotrexate or Mycophenolate mofetil to Prednisone therapy may be more effective
  • Additional processes (e.g. Hypertension or Congestive Heart Failure) will require disease specific treatments
  • In advanced disease processes, Cardiac or Vascular Surgery or Interventional Radiology may be required for angioplasty, stenting, or valvular repair

Disposition

  • This will require clinical judgement on a case by case basis
  • Patients should have a solid follow up plan with their primary care doctor or rheumatologist prior to discharge
  • Patients with severe aortic regurgitation, large aortic aneurysm, or another concerning end product of this disease process will likely require inpatient admission with specialty service care
