Purpose : To evaluate the embolic effect and pathologic change in the kidney after
infusion of 50% acetic acid in the renal artery.
Materials and Methods : Five kidneys were embolized with 50% acetic acid mixed with
saline (group A) and five were embolized with 50% acetic acid mixed with contrast
medium (group B). Four rabbits (2 from group A and 2 from group B) were sacrificed
during the first day and the remaining six, 28 days after embolization. To determine the
effect of embolization and pathologic findings, the two groups were compared.
Results : Complete occlusion of the renal artery was observed in both groups ;
histologic findings indicating tubular necrosis and blood clots within the renal artery
were noted one day after embolization. After four weeks, complete necrosis of the renal
arterial wall and tubular cells had occurred. The procedures required for embolization
were easier in group B because the extent of embolization could be controlled by
fluoroscopy.
Conclusion : At 50% dilution after mixing with contrast medium, the embolie effect of
acetic acid is perfect ; because the embolic material is visualised the procedure was
easier to control than embolization with alcohol. Acetic acid can, therefore, be used as
an effective embolic agent in renal artery embolization.
