Fibrin sealant in interventional radiology: a preliminary evaluation.

Tisseel, a fibrin sealant not approved for use in the United States, was tested in abdominal fistulas and sinuses (13 patients) and interventional biliary procedures (11 patients). The two components of Tisseel were introduced via a double-lumen catheter and formed a fibrin gel at the point of contact. Tracts were sealed permanently in seven fistulas and sinuses and in all 11 biliary cases.
