Selective intraarterial steroid injection in ulcerative colitis

K Hiramatsu, H Asakura, S Baba

    Acta Radiologica: Diagnosis
    |May 1, 1976

    Summary

    Intra-arterial steroid injections, specifically prednisolone, show promising results for treating ulcerative colitis. This angiography study found hypervascularity in affected areas and good outcomes with direct arterial drug delivery.

    Methods in molecular medicine·2011

    Area of Science:

    • Gastroenterology
    • Interventional Radiology

    Background:

    • Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
    • Current treatments for UC have limitations and potential side effects.

    Purpose of the Study:

    • To evaluate the efficacy of direct intra-arterial prednisolone injections in patients with ulcerative colitis.
    • To assess angiographic findings in ulcerative colitis patients undergoing treatment.

    Main Methods:

    • Angiography was performed on 11 patients diagnosed with ulcerative colitis.
    • Prednisolone was administered directly into the superior and inferior mesenteric arteries in 10 of these patients.
    • Angiographic features, including hypervascularity and venous filling patterns, were analyzed.

    Main Results:

    • Hypervascularity of the inflamed bowel segments was a frequent observation in the angiograms.
    • Early venous filling, indicative of altered blood flow, was observed in 5 out of 11 patients.
    • Intra-arterial steroid injections demonstrated positive therapeutic effects.

    Conclusions:

    • Direct intra-arterial administration of prednisolone appears to be an effective treatment modality for ulcerative colitis.
    • Angiography can reveal characteristic vascular changes in ulcerative colitis and monitor treatment response.
