title: [Interventional radiology for chronic hemorrhoids complicated by hemorrhage].
abstract: Based on the concept of the occurrence and development of hemorrhoids from the abnormally changed groups of cavernous bodies of the submucous membrane of the rectal transitional area, the authors used selective dearterialization of hyperplastic cavernous tissue that is simultaneously internal hemorrhoids. The essence of the new treatment is superselective X-ray endovascular catheterization of the superior hemorrhoidal artery and embolization of its distal branches which supply blood to rectal cavernous body. The outcomes of 337 Milligan-Morgan hemorrhoidectomies and 49 X-ray endovascular embolizations of the superior hemorrhoidal artery were analyzed in patients with chronic hemorrhoids complicated by hemorrhages. Emphasis is laid on the advantages of X-ray endovascular occlusion of the superior hemorrhoidal artery over conventional treatment.
