概括

在线圈栓塞过程中降低脉率显著减少了患者的辐射暴露. 这种技术有效地降低了辐射剂量,而不会增加脑动脉瘤治疗中的术后并发症.

科学领域:

干预性神经辐射学
医学物理医学物理
患者安全患者安全

背景情况:

线圈栓塞是一种最少的侵入性手术,但辐射暴露是令人担忧的.
之前的研究没有具体量化了线圈栓塞过程中的辐射暴露.
优化成像参数对于降低内血管程序中的辐射剂量至关重要.

研究的目的:

为了研究较低的脉冲率对线圈栓塞过程中的辐射暴露的影响.
为了确定减轻脉率是否会影响患者的安全和术后并发症.
为了建立脉冲率和辐射剂量指标之间的相关性.

主要方法:

70名患者的辐射数据和临床特征的回顾性分析.
以标准 (每秒7.5) 与较低 (每秒4) 脉率进行的手术的比较.
统计分析以评估脉冲率,患者吸收剂量 (AK) 和剂量区域产物 (DAP) 之间的关系.

主要成果:

在每秒4的过程中,与每秒7.5 (4760 mGy) 相比,AK (2580.7 mGy) 和DAP显著减少.
在较低的脉冲率和减少的辐射暴露之间发现了显著的相关性 (p = 0.000002对于DAP和AK).
没有观察到脉率和术后并发症之间的显著相关性.

关键词:

结论:

将脉冲率降低到每秒4是降低线圈栓塞期间辐射暴露的有效策略.
这种修改可以在不损害患者安全或增加并发症率的情况下实施.
降低脉率是神经干预手术中降低剂量的一种可行的方法,例如脑动脉瘤栓塞.
