    Selective visceral angiography is effective for diagnosing gastrointestinal bleeding, especially obscure cases caused by angiodysplasia. This imaging technique also offers therapeutic benefits through embolization.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology

    Background:

    • Gastrointestinal bleeding (GIB) presents diagnostic challenges, particularly obscure GIB.
    • Angiodysplasia is an underdiagnosed cause of chronic and obscure GIB.

    Purpose of the Study:

    • To evaluate the diagnostic and therapeutic efficacy of selective visceral angiography in patients with GIB.
    • To identify the common causes of GIB diagnosed via angiography.

    Main Methods:

    • 160 selective visceral angiograms were performed in 145 patients with GIB.
    • Patients were categorized into emergency (Group A) and elective (Group B) procedures.

    Main Results:

    • Angiography demonstrated a higher positive rate in emergency procedures (87%) versus elective (74%).

    Related Experiment Videos

  • Angiodysplasia was the most frequent finding in elective procedures (43 patients), often in those with prior negative investigations.
  • Embolization was performed in 36% of Group A and 10% of Group B patients with positive findings.

    • Conclusions:

    • Selective visceral angiography is a valuable tool for diagnosing GIB, including obscure cases attributed to angiodysplasia.
    • Angiography offers successful therapeutic intervention, such as embolization, for GIB management.
