ABSTRACT
PURPOSE:
To evaluate the therapeutic effectiveness of absolute ethanol and gelfoam particles and the degree of vascular recanalization after gelfoam embolization. MATERIALS ANDMETHODS:
Transcatheter renal arterial embolization(TRAE) was performal in 16 rabbits ; Eight were embolized with absolute ethanol, and eight with gelfoam particles. Of this total, three died less than one week after embolization. Pre- and post embolization angiographies at five minutes, one week, two weeks(gelfoam group only) and 5-6 weeks after embolization were performed. Six rabbits were sacrificed at one week, and seven at 5-6 weeks after embolization. Pathologic examination was performed.RESULTS:
The ethanol group(n=6) showed complete occlusion of the main renal artery on follow-up angiography at one week and 5-6 weeks after embolization. The pathologic finding was complete total necrosis of embolized kidneys. The gelfoam group(n=7) showed partial recanalization of renal arteries in follow upangiography at one week, two weeks and 5-6 weeks after embolization. The pathologic finding was partial lysis ofgelfoam particles within intrarenal arteries.CONCLUSION:
Absolute ethanol can be used as a permanent embolicagent and gelfoam as a temporary such agent in various clinical applications. Gelfoam, however, did not show complete recanalization on angiography and pathology at six weeks after embolization.
