    Transcatheter embolization effectively controlled lower gastrointestinal bleeding in most patients. While successful for active bleeding, recurrence occurred in some cases, necessitating further long-term evaluation of this interventional radiology technique.

    Area of Science:

    • Interventional Radiology
    • Gastroenterology
    • Vascular Medicine

    Background:

    • Lower gastrointestinal bleeding (LGIB) poses significant clinical challenges.
    • Identifying the precise bleeding source is crucial for effective management.
    • Transcatheter embolization offers a minimally invasive therapeutic option.

    Observation:

    • Seven patients with LGIB underwent transcatheter embolization.
    • Hemorrhage was initially controlled in 5 actively bleeding patients.
    • Two patients with intermittent bleeding from vascular dysplasias experienced recurrence.

    Findings:

    • Transcatheter embolization demonstrated high initial success rates for acute LGIB.
    • Preoperative angiographic localization is recommended for identifying bleeding sites.

  • Embolization can potentially obviate the need for surgery in LGIB cases.

    • Implications:

    • Transcatheter embolization is a viable option for managing LGIB, potentially avoiding surgery.
    • Partial colectomy remains an alternative if embolization fails or complications arise.
    • Long-term follow-up is essential to fully assess the definitive role of embolization in LGIB treatment.
