Hemorrhoidal artery embolization

Hemorrhoids before and after hemorrhoidal artery embolization

Hemorrhoidal artery embolization (HAE, or hemorrhoid artery embolization) is a non-surgical treatment of internal hemorrhoids.[1]

The procedure involves blocking the abnormal blood flow to the rectal (hemorrhoidal) arteries using microcoils and/or microparticles to decrease the size of the hemorrhoids and improve hemorrhoid related symptoms, especially bleeding.[2] It is a minimally invasive therapy that can be performed as an outpatient procedure.[3]
