  • Title: Therapeutic embolization with long-term occluding agents and their effects on embolized tissues.
    Author: White RI, Strandberg JV, Gross GS, Barth KH.
    Journal: Radiology; 1977 Dec; 125(3):677-87. PubMed ID: 928692.
    Abstract:
    The effects of long-term occlusion of branches of the celiac and renal arteries were studied in 13 pigs, using isobutyl 2-cyanoacrylate (ibc), the Gianturco-Anderson-Wallace wool coil, and lvalon. IBC permanently occluded 2- to 8-cm lengths of both vessels, including their branches so that collateral circulation was not able to preserve the tissue supplied by the occluded artery. Gastric ulcers, splenic and hepatic infarcts, and large, sterile biliary cysts were observed on postmortem examination. Permanent occlusion was also observed with the wool coil and lvalon, but the pathological results were much less deleterious. The authors conclude that IBC is presently unsafe for use in branches of the celiac artery.
