The balloon-assisted technique is one of the methods used for cerebral aneurysm embolization. There are several applications of assisting balloons such as remodeling the neck of cerebral aneurysms, protecting blood vessel branches, and stabilizing the microcatheter. In this study, we measured the pressure inside inflated assisting balloons to assess safety or procedure.
A T-junction silicone model was used. The pressure inside the balloon inflated to the set herniation levels in the T-junction model was measured using a fiber pressure sensor. We compared the pressure and difference between each assisting balloon.
The pressure required for inflating the balloon to the set herniation level in the T-junction model varied depending on the type of assisting balloon. The results suggest that differences in pressure among inflated balloons are likely attributable to differences in the materials used in the lumens of the balloons.
The pressure inside various inflated assisting balloons was measured for comparison and differences were found. This experiment contributes to the safety of the balloon-assisted technique.
球囊辅助技术是用于脑动脉瘤栓塞的方法之一。辅助球囊有多种应用，如重塑脑动脉瘤颈部、保护血管分支以及稳定微导管。在本研究中，我们测量了充气辅助球囊内部的压力以评估安全性或操作过程。
使用了一个T型硅胶模型。通过光纤压力传感器测量在T型模型中充气至设定疝出水平时球囊内部的压力。我们比较了每个辅助球囊的压力及差异。
在T型模型中，将球囊充气至设定疝出水平所需的压力因辅助球囊类型而异。结果表明，充气球囊之间的压力差异可能归因于球囊内腔所用材料的差异。
测量了各种充气辅助球囊内部的压力以进行比较并发现了差异。该实验有助于球囊辅助技术的安全性。
