    Area of Science:

    • Interventional Radiology
    • Gastroenterology
    • Vascular Surgery

    Background:

    • Gastrointestinal bleeding and intestinal ischemia present significant diagnostic and management challenges.
    • Endoscopic and conservative measures may be insufficient for severe cases.

    Purpose of the Study:

    • To review the diagnostic and therapeutic applications of angiography in gastrointestinal bleeding and intestinal ischemia.
    • To outline current strategies for utilizing angiography in these conditions.

    Main Methods:

    • Diagnostic and interventional angiography.
    • Radionuclide studies for guiding angiography in rectal bleeding.
    • Intra-arterial infusions (vasopressin, papaverine) and transcatheter embolization.
    • Angioplasty for mesenteric arterial stenoses.

    Main Results:

    • Angiography is indicated for upper GI bleeding when endoscopy is unavailable or inconclusive.
    • Radionuclide studies help select patients for angiography in rectal bleeding, avoiding unnecessary procedures.
    • Angiography is crucial for differentiating occlusive from non-occlusive intestinal ischemia.
    • Interventional techniques effectively control bleeding and manage ischemic conditions.

    Conclusions:

    • Angiography is a vital tool for the diagnosis and management of gastrointestinal bleeding and intestinal ischemia.
    • Tailored angiographic approaches, including interventional procedures, improve patient outcomes.
    • Integration with other modalities like radionuclide studies optimizes diagnostic yield.
