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 ...

[10] HAE involves the blockage of 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 ...

It descends into the pelvis between the layers of the mesentery of the sigmoid colon, crossing the left common iliac artery and vein. It divides, opposite the third sacral vertebra into two branches, which descend one on either side of the rectum.
Hemorrhoids are fed by arteries and drained by veins. The arterial blood supply is based on the superior rectal (hemorrhoidal) artery. Just as veins in the leg weaken and become prominent, hemorrhoidal veins also may become varicose, resulting in internal hemorrhoids or “piles”. Internal hemorrhoids are divided into four grades.
A common indication for angiography is to evaluate and guide treatment for internal (e.g. gastrointestinal) bleeding. [12] Angiography may also be used during hemorrhoidal artery embolization for treatment of symptomatic hemorrhoids. [13]
