Outcome Measures

Primary Outcomes (3)

  • Change in French bleeding score (FBS)

    The French bleeding score assesses the intensity of hemorrhoidal bleeding with scores ranging from 0 (no bleeding) to 9 (daily bleeding with anemia requiring blood transfusions)

    Baseline, 1, 3, 6 and 12 months

  • Adverse Events

    Number of subjects to experience adverse events defined by 1) Common Terminology Criteria for Adverse Events (CTCAE) v6.0, 2) Society of Interventional Radiology \[SIR\] classifications of postoperative complications and 3) Clavien-Dindo Classification

    Day 1 and 1, 3, 6 and 12 months

  • Diagnostic accuracy of pre-embolization Computed Tomography Angiography (CTA)

    Diagnostic accuracy and inter-rater agreement of pre-embolization CTA in identifying the hemorrhoidal arteries supplying the hemorrhoidal cushion

    Baseline (pre-embolization)

Secondary Outcomes (7)

  • Visual Analog Scale (VSS) Pain

    Baseline, 1, 3, 6 and 12 months

  • Visual Analog Scale (VAS) for Quality of Life

    Baseline, 1, 3, 6 and 12 months

  • Goligher Prolapse Score

    Baseline, 1, 3, 6 and 12 months

  • Hemorrhoidal Bleeding Score (HBS)

    Baseline, 1, 3, 6 and 12 months

  • Hemorrhoidal Severity Score (HSS)

    Baseline, 1, 3, 6 and 12 months

  • +2 more secondary outcomes
