Purpose:For the occlusion of a high-flow fistula, glue is an effective embolic agent. In order to visualize glue fluoroscopically, we demonstrated the different embolic effect of pure glue and a glue-tungsten mixture. Materials and Methods:A flow phantom model consisted of a circulating pump(Simon varistaltic pump, Manostat Corporation, U.S.A.) connected to a tygon tube(S-50-HL, Norton Performance Plastic Corporation, U.S.A.);flow was maintained by saline at about 4ml/sec. The tygon tube(4.8mm inner diameter) was cut to a length of 60cm;a Y-connector was fitted to the end of its inflow tract and a gauze filter to the end of the outflow tract. A microcatheter was introduced through the Y-connector into the proximal portion of the tube. 1.0cc of pure glue and 0.25g glue-tungsten mixture were each injected rapidly, three times, and in order to observe flow status within the tygon tube, ink was injected. The shape of the glue cast and the pattern of flow arrest were observed and the length of the cast was measured. In an animal experiment, 0.5cc glue with or without tungsten powder was rapidly injected into the brachial artery of the pig and angiographic findings were compared before and after injection. Results:In the flow phantom experiment, the injection of pure glue resulted in complete flow arrest within the tygon tube;the length of the cast was 7 cm. Another injection resulted in incomplete flow arrest and a cast length of 16cm. A further injection resulted in the complete passage of glue into the gauze filter, and complete flow arrest. An injection of glue-tungsten mixture resulted in incomplete flow arrest, and a cast length of 30cm;in two other injection, glue-tungsten mixtures passed the tygon tube and gauze filter without flow arrest. In the animal experiment, pure glue resulted in complete flow arrest with minimal distal migration of the glue cast. In contrast, glue-tungsten mixture resulted in incomplete flow arrest or distal migration of the cast, with minimal collateral development. Conclusion:Pure glue resulted in complete flow arrest within a short distance of the catheter tip. In contrast, a glue-tungsten mixture tended to result in incomplete flow arrest and more distal migration than was the case with pure glue. In a high-flow vascular leison, a glue-tungsten mixture therefore appears to result in more distal migration than pure glue without tungsten.
