title: [Uterine artery embolization using gelatin sponge in a miniature pig: a study of arterial size and the distribution of embolic materials].
abstract: Uterine artery embolization using gelatin sponge particles was performed in a miniature pig, and the distribution of the particles was investigated. The particles spread in the cervix and proximal portion of the left horn. Histological study revealed embolic material in both the myometrium and endometrium. Several particles were found even in arteries smaller than 100 microm in diameter in the endometrium. Further studies should address the risks of gelatin sponge particles in the peripheral arteries of the uterine endometrium, as they may induce inflammatory processes and evoke complications including infection and menopause.
