Rectal Artery Embolization

Treatment for grade I to grade III hemorrhoids

Rectal artery embolization is a vascular treatment technique for grade I to grade III hemorrhoids. This procedure has shown significant symptom improvement in all treated patients, offering outcomes comparable to transrectal surgical approaches, while providing several key advantages.

The long-term results of embolization are similar to those of surgery, making it a highly effective option. By eliminating the need for major surgical intervention in most cases, this outpatient procedure not only enhances patients' quality of life but also significantly shortens recovery time.

The technique involves selective catheterization of the inferior mesenteric artery, with bilateral embolization of the rectal arterial branches using coils and microspheres. This allows for effective treatment without the risks typically associated with open surgery.
