Selective embolization can effectively alleviate bleeding symptoms in patients with anorectal hemangioma.

In this manuscript, I comment on the article by Pospisilova et al published in the recent issue of the journal, in which selective embolization was used to treat anorectal hemangioma, a rare disease causing lower gastrointestinal bleeding. Anorectal hemangioma can easily be mistaken; for example, the patient in this case was previously misdiagnosed with ulcerative colitis. Choosing the appropriate tests and understanding the typical manifestations of anorectal hemangioma under colonoscopy, computerized tomography, magnetic resonance imaging and other tests are beneficial for diagnosis. The patient presented with intermittent rectal bleeding despite treatment with azathioprine and mesalazine and required blood transfusions since the degree of rectal bleeding worsened. Selective embolization successfully alleviated the patient's bleeding symptoms and avoided the need for repeated blood transfusions. Tranexamic acid may be useful, considering that the patient still has bleeding symptoms and requires parenteral iron supplementation.
