Therapeutic blockade of arteries using compressed Ivalon
C Zollikofer, WR Castaneda-Zuniga, C Galliani, JA Rysavy, A Formanek and K Amplatz
A new technique for embolization with compressed Ivalon plugs is described.
Fourteen arteries--six renal, three splenic, two pulmonary, one left
gastric, and two abdominal aortas--were occluded in six dogs. In one case
of renal artery embolization, three plugs were used, and in one case of
abdominal aorta embolization, two were needed for total occlusion. In all
other cases only one plug was used. Total occlusion was angiographically
demonstrated up to five months following embolization in all but one case.
In this case, recanalization was thought to have occurred because of
overcompression of the Ivalon plug.
