STABLE Score (TEVAR Risk) Calculator

  • Shock on Presentation (Yes = 1, No = 0)
  • Malperfusion (Yes = 1, No = 0)
  • Age > 70 years (Yes = 1, No = 0)
  • Previous Aortic Surgery (Yes = 1, No = 0)
  • STABLE Score (TEVAR Risk): Explanation and Clinical Context
    STABLE Score is a validated tool to predict 30-day mortality in patients undergoing thoracic endovascular aortic repair (TEVAR) for acute complicated type B aortic dissection.
    It incorporates four key clinical factors: Shock at presentation, presence of Malperfusion, Age >70 years, and Previous Aortic Surgery.
    Each factor scores 1 point if present, and the total score ranges from 0 to 4.
    Patients are stratified into low, intermediate, or high risk for 30-day mortality based on their total score, aiding clinicians in risk assessment, procedural planning, and patient counseling.
