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 ...
Hemorrhoidal artery embolization (HAE) is an additional minimally invasive procedure performed by an interventional radiologist. [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 ...
The superior rectal artery is the continuation of the inferior mesenteric artery. 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.
Embolization: Placement of a metallic coil or embolic substance (gel-foam, poly-vinyl alcohol) to block blood through to a blood vessel, either to stop bleeding or decrease blood flow to a target organ or tissue.

The middle rectal artery usually arises from the internal iliac artery. [1] It is distributed to the rectum above the pectinate line. [2] It anastomoses with the inferior vesical artery, superior rectal artery, and inferior rectal artery. [2] In males, the middle rectal artery may give off branches to the prostate and the seminal vesicles.

The inferior rectal artery arises from the internal pudendal artery as it passes above the ischial tuberosity.. Piercing the wall of the pudendal canal, it divides into two or three branches which cross the ischioanal fossa, and are distributed to the muscles and integument of the anal region, and send offshoots around the lower edge of the gluteus maximus to the skin of the buttock.
