Haemorrhoidal artery embolization (Emborrhoid) is a novel method for the treatment of haemorrhoids. Through the catheterization of the femoral artery and a selective angiogram of the inferior mesenteric artery, embolic agents are delivered to occlude the SRA. Despite the technical success rate has been reported to reach 93%-100%, clinical success ranges between 63% and 94% with rebleeding occurring in 13.6% of cases due to the presence of a significant MRA in 24% of cases [BIBLIO} . There is no data in the literature on how the arterial flow changes after the treatment.~The primary aim of the present study was to assess the reduction in the blood supply by comparing the hemorrhoidal arterial systolic peak before and after Hemborrhoid by using endoanal ultrasound (EAUS) combined with doppler. The secondary aim was to evaluate if a relation exists between the reduction and the efficacy of this treatment by the Hemorrhoidal Bleeding Score.
To evaluate the usefulness of endoanal ultrasound in the evaluation of emorrhoidal artery embolization outcomes
