[X-ray endovascular embolization of the superior rectal artery: New potentialities in the surgical management of chronic hemorrhoids].

Based on the concept of occurrence and development of hemorrhoids from pathologically altered groups of cavernous bodies of the anal submucosa, the author used dearterialization of hyperplastic cavernous tissue for the treatment of hemorrhoids. The treatment involves superselective catheterization and material embolization of the superior rectal artery. The characteristics of 86 remedial embolizations of the superior rectal artery and routine treatments (sclerotherapy, latex-ring ligation, cryotherapy, and surgical hemorrhoidectomy) for chronic hemorrhoids. Emphasis is placed on the advantages of embolization methods over conventional low-invasive and surgical treatment.
