However, there is a permanent debate in biomedical research concerning the reproducibility of animal models and their applicability to human models. I read the article by Tradi et al. published in this issue of CVIR with great interest [
1]. In this recently-published laboratory study conducted in 2016, the authors investigated the outcomes of healthy upper rectal artery embolisation in a swine model using three types of embolic agents. Despite interesting results, it is necessary to highlight that haemorrhoidal disease does not occur in swine. …
