在实验性血管模型中评价2个球囊之间的短段弹簧圈栓塞用于紧密填塞的可行性。由5名介入放射科医生进行了3种弹簧圈栓塞技术，如下所示：（1）近端球囊技术（近端BT）涉及近端球囊充盈和球囊上的弹簧圈展开，（2）远端球囊技术（远端BT）涉及远端球囊充盈和充盈球囊近端侧的弹簧圈展开，和（3）双球囊技术（DBT），涉及在2个充盈球囊之间展开弹簧圈。我们使用直径10 mm、长度200 mm的液压弹簧圈。灌注管中2个充盈球囊之间的距离设定为5 mm，每个手术进行两次。对使用3种技术获得的栓塞部位的展开弹簧圈质量和体积栓塞率（VER）的纵向长度进行了统计学比较。在近端BT、远端BT和DBT中，展开的弹簧圈质量的纵向长度分别为26 mm（范围，21-34 mm）、10 mm（8-14 mm）和5 mm（5-5 mm）。中位VERs分别为15.9%（12.2-19.4%）、41.4%（29.6-51.8%）和82.9%（82.9-82.9%）。在3种技术之间观察到长度和VERs的显著差异（p < 0.001）。与近端BT和远端BT相比，DBT在实验血管模型的短节段中实现了水弹簧圈的紧密填塞，表明DBT是该模型中的最佳栓塞技术。
To evaluate the feasibility of short-segment coil embolization between 2 balloons for tight packing in an experimental vascular model. Three 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. The 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). DBT 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.
