Rectal Artery Embolization for the Treatment of Hemorrhoidal Disease

Abstract

The term “hemorrhoid” is commonly invoked to characterize the pathologic process of symptomatic hemorrhoidal disease instead of the normal anatomic structure. While often treated with conservative measures, rectal artery embolization offers a minimally invasive alternative for patients with persistent or severe symptoms. This technique involves blocking the blood supply to the hemorrhoids using embolic agents, reducing blood flow, and alleviating symptoms. This review explores the clinical evaluation, techniques, and outcomes associated with rectal artery embolization for the treatment of hemorrhoidal disease. A discussion of the pathophysiology of hemorrhoids, the anatomy of rectal arteries, and the embolization procedure is provided in detail. Additionally, the safety and efficacy of the technique, including potential complications and outcomes, are reviewed.
