Purpose: The purpose of this study was to assess the safety and efficacy of using particles only in the embolization of the hemorrhoidal arteries for the management of hemorrhoids. Subjects and Methods: This is a retrospective study for patients treated between March 2015 and December 2018. We treated 33 patients, 13 men and 20 women with a mean age of 37 years (range: 18–70 years), in which 11 patients had Grade II hemorrhoids and 22 had Grade III hemorrhoids. Technical and clinical successes together with procedural complications were assessed. Results: The technical success rate was 100%. No minor or major complications have been reported. No cases of anorectal ischemia, anal incontinence, hemorrhoidal thrombosis, or complications related to femoral arterial puncture have occurred. Follow-up was at 3 months and 12 months postembolization. Clinical success was observed in 32 patients (96.9%) with improvement by at least 2 points of the French bleeding score at 3 months postembolization. Conclusion: The use of particles alone in the embolization of hemorrhoidal arteries whether from the superior rectal artery and/or from the middle and inferior rectal arteries can offer a safe and effective treatment option.

Background: Trans-catheter renal arterial embolization (RAE) has emerged as a possible alternative to surgery in the management of iatrogenic renal arterial injuries. Objective: To discuss the role of renal arterial embolization in patients with iatrogenically-induced renal arterial injuries. Methodology: All cases were done at the Interventional Radiology Unit, Ain Shams University Hospital. Results: Technical and Clinical success rates of the RAE reached 90% for each, with post procedural complications that only amounted up to 30%, half of which was the post embolization syndrome that presents as fever, leukocytosis and pain and is treated conservatively. Conclusion: Renal artery embolization has proven to be a safe, minimally invasive option in the treatment of iatrogenic renal arterial injuries achieving high technical and clinical success rates.
