[Interventional radiology of chronic hemorrhoids].

Basing on the concept of hemorrhoids from pathologically changed groups of cavernous bodies of submucous layer of rectal transitional zone, the author used for the first time selective dearterialization of hyperplastic cavernous bodies which were at the same time three internal hemorrhoidal nodes. The therapeutic method consisted in roentgenoendovascular catheterization of the superior hemorrhoidal artery and embolization of its distal branches delivering blood to the internal hemorrhoidal nodes. Results of roentgenoendovascular treatment of 34 patients suffering from chronic hemorrhoids are analyzed. The author emphasizes the advantages of roentgenoendovascular occlusion of the superior hemorrhoidal artery in comparison with traditional drug therapy and surgery. No recurrences were recorded over 24 months after the intervention.
