PurposeTo evaluate the feasibility of short-segment coil embolization between 2 balloons for tight packing in an experimental vascular model.

Materials and MethodsThree coil embolization techniques were performed by 5 interventional radiologists as follows: 1 proximal balloon technique proximal BT which involved proximal balloon inflation and coil deployment over the balloon, 2 distal balloon technique distal BT which involved distal balloon inflation and coil deployment at the proximal side of the inflated balloon, and 3 double-balloon technique DBT which involved coil deployment between 2 inflated balloons. We used a 10-mm-diameter and 200-mm-long hydrocoil. The distance between the 2 inflated balloons was set at 5 mm in the perfused tube, and each procedure was performed twice. The longitudinal lengths of the deployed coil mass and volume embolization rates VERs at the embolization site obtained using the 3 techniques were compared statistically.

ResultsThe longitudinal lengths of the deployed coil mass were 26 mm range, 21–34 mm, 10 mm 8–14 mm, and 5 mm 5–5 mm in proximal BT, distal BT, and DBT, respectively. The median VERs were 15.9% 12.2–19.4%, 41.4% 29.6–51.8%, and 82.9% 82.9–82.9%, respectively. Significant differences in the lengths and VERs were observed among the 3 techniques p < 0.001.

ConclusionDBT achieved the tight packing of a hydrocoil in a short segment of an experimental vascular model compared with proximal BT and distal BT, suggesting DBT as the optimal embolization technique in this model.
