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.
“痔”这个术语通常用于描述有症状的痔病的病理过程，而非正常的解剖结构。虽然痔病常采用保守治疗措施，但对于有持续或严重症状的患者，直肠动脉栓塞术提供了一种微创替代方案。该技术通过使用栓塞剂阻断痔的血液供应，减少血流，从而缓解症状。本文综述探讨了直肠动脉栓塞术治疗痔病的临床评估、技术及疗效。详细阐述了痔的病理生理学、直肠动脉的解剖结构以及栓塞过程。此外，还对该技术的安全性和有效性，包括潜在并发症及疗效进行了综述。
