Outline of Final Research Achievements

Transarterial embolization (TAE) are less invasive procedures for adrenal neoplasms. However, it is sometimes difficult to select the appropriate feeding arteries in TAE. It is relatively easy for the interventional radiologists who are familiar with adrenal venous sampling (AVS) to select the bilateral adrenal veins. Therefore, venous approach is feasible to obliterate the adrenal gland. Absolute ethanol is the most appropriate embolic agent for balloon occluded adrenal venous embolization owing to effective results in histopathological and angiographic evaluation.
Moreover, we evaluated the changes over time and effects of balloon occluded adrenal venous embolization using absolute ethanol in order to review MRI findings, histopathological findings and hormonal examinations. Then, balloon occluded adrenal venous embolization using absolute ethanol caused partial adrenal hemorrhagic infarction and it was one of procedure to cause adrenal obliteration.
