ABSTRACT


Th e authors, a case series of five cases of angiomyolipomas (AMLs), embolized with a high ethanol:ethiodol ratio of 6:1 emulsion at a single tertiary center. Although ethanol as an embolic agent has been reported in the past for AMLs, much higher ratios of ethiodol were used, and administration is typically performed using an occlusion balloon. Two of the patients were incidentally diagnosed, while the other four were diagnosed after hematuria workup. Of the five patients, only one developed postembolization syndrome. Otherwise, no complications, recurrences, or reinterventions are reported. Our higher ratio seems to allow for adequate radio-opacity of the emulsion with minimal negative dilution effect.
