Long-term radiographic-pathologic follow-up of patients treated with visceral transcatheter occlusion using isobutyl 2-cyanoacrylate (Bucrylate).

Visceral transcatheter occlusive therapy was performed with isobutyl 2-cyanoacrylate (Bucrylate) in 14 patients. Of 10 patients who subsequently died, postmortem examination in 6, performed 2--196 days post-embolization, showed only a mild histiocytic foreign body giant cell reaction to Bucrylate. The reaction was confined to the vessel lumina and did not involve the vessel walls or contiguous parenchymal tissues. Clinical and radiographic follow-up in the other 4 patients (range = 30--180 days) showed no evidence of untoward reaction to Bucrylate. No ischemic or inflammatory complications were observed in any of the peripheral organs.
