The arteries and kidneys of 10 dogs were embolized with nitinol arterioembolizer in conical spiral and rugby spiral forms (NT-CRE) and observed with light and electron microscopes. The results showed that mechanical compressive atrophy was induced in the target arteries and ischemic atrophy in the target kidneys. No other abnormal histological changes were found. This study suggests that NT-CRE is a promissing, therapeutic arterioembolizer.
