In plain words

What the trial is, and whether it could suit you

Hemorrhoidal artery embolization (HAE) is a novel treatment for symptomatic internal hemorrhoids. HAE involves the deliberate blockage (embolization) of enlarged rectal or hemorrhoidal arteries leading to reduction of abnormal blood flow to the hemorrhoidal tissue. The aim of HAE is to the improve hemorrhoid related symptoms, especially bleeding. Initial reports of HAE have demonstrated that it both safe and effective. Following an initial clinic visit to determine trial candidacy, enrolled patients will be subsequently treated with HAE. Patients will be followed for a year with clinic follow-up visits at 1, 3, 6 and 12 months.
