Summary
Hemorrhoidal artery embolization (HAE) is a safe and effective minimally invasive treatment for severe hemorrhoidal bleeding. Studies show high success rates (63-94%) with few complications, offering a valuable option for selected patients.
Area of Science:
- Interventional Radiology
- Gastroenterology
Background:
- Hemorrhoidal bleeding can be debilitating and unresponsive to conventional therapies.
- Minimally invasive treatments are increasingly sought for hemorrhoidal disease.
Purpose of the Study:
- To provide an overview of rectal artery embolization (RAE) for bleeding hemorrhoids based on current literature.
- To assess the feasibility, efficacy, and safety of RAE.
Main Methods:
- A comprehensive literature review was conducted using PubMed-Medline.
- Relevant studies on hemorrhoidal artery embolization were identified and summarized narratively.
Main Results:
- RAE is feasible, effective, and safe for treating bleeding hemorrhoids.
- Published data includes nearly 250 patients with high technical success and clinical success rates (63-94%).
- No major complications were reported; repeat procedures are possible for recurrences.
Conclusions:
- Rectal artery embolization is a valuable addition to the treatment options for bleeding hemorrhoidal disease.
- Appropriate patient selection is crucial for successful outcomes.
- Anatomical variants may necessitate further investigation or repeat sessions.

45
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:24Esophageal Varices-I: Introduction
71
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
