ABSTRACT
PURPOSE:
To evaluate the potential usefulness of the balloon-occluded histoacryl glue embolization (B-glue) technique. MATERIALS ANDMETHODS:
Both flow-dependent (no balloon occlusion) and B-glue techniques were used for 24 intercostal arteries of two female swine. N-butyl 2-cyanoacrylate (NBCA) was diluted with lipiodol to a 50 % solution, which was infused after occluding the arteries with microballoon catheters. The embolization range, fragmentation, reflux, adhesion, and glue particle attachment were compared between flow-dependent and B-glue techniques.RESULTS:
The B-glue technique was performed in a controlled fashion resulting in successful arterial occlusion without fragmented migration of the injected glue cast. Reflux occurred less frequently with the B-glue technique and was significantly different (p = 0.039) [Corrected] from that for the flow-dependent technique. Catheters were safely removed from the arterial walls, although in one instance (8.3 %), large glue particles were found to be attached to the catheter tip on removal. Conversely, the flow-dependent technique was more difficult to control and resulted in several instances of higher rates of fragmentation.CONCLUSION:
The B-glue technique can efficiently control NBCA delivery with lower rates of reflux.
