Resolution of Symptoms after Parent Artery Occlusion Treatment for Giant Cavernous Carotid Artery Aneurysms

引用

World Journal of Neuroscience 2014年第4期4卷 334-340页

作者： Zenghui Qian Tangming Peng wenjun Ji Jing Wu Huibin Kang xiaolong wen wenjuan Xu Aihua Liu Youxiang Li Beijing Tiantan Hospital Capital Medical University Beijing China Department of Interventional Neuroradiology Beijing Neurosurgical Institute Beijing China

Background and Objective: Giant cavernous carotid artery aneurysms (CCAAs) often produce a variety of neurological deficits, primarily those related to ophthalmoplegia/paresis and headache. This study was designed to evaluate the resolution of symptoms after parent artery occlusion (PAO) treatment for giant CCAAs. Methods: We retrospectively reviewed a series of 17 consecutive giant CCAAs treated with PAO treatment. All patients were evaluated by balloon occlusion test (BOT) before treatment. Patients who could tolerate BOT were treated by PAO. The following outcomes were analyzed: angiographic assessment, evolution of symptoms and outcome at clinical follow-up using modified Rankin Scale (mRS). Results: A total number of 17 giant CCAAs were treated by PAO. The initial post-procedure and follow-up angiogram revealed complete occlusion in all patients, no new lesion was detected. Periprocedural infarcts occurred in 1 patient (5.9%). Procedure-related mortality and morbidity were 0% and 5.9%, respectively. At mean 31.8 months clinical follow-up, symptoms had disappeared in 7 (41.2%) of the patients, partially improved in 5 (29.4%), remained unchanged in 4 (23.5%) and worsened in 1 (5.9%) of cases. Sixteen (94.1%) patients presented a good clinical outcome (mRS 0 - 1). Conclusion: Most patients in our series improved or remained stable after PAO. The results of this study indicate that PAO can improve the outcome of those symptomatic giant CCAAs if BOT can be tolerated.

传统的基于电涡流的多周期位移传感器由于输出信号的周期重复性,难以解决断电重启后的绝对位置识别问题。提出一种基于电涡流的新型双极直线位移传感器。经过理论与仿真分析,验证了随着滑片的滑动,接收线圈中感应电压的幅值呈现正余弦变化。设计了双极敏感结构,通过上极多周期接收线圈保证位移的精确测量。下极布置单周期接收线圈对上级所处周期进行识别。通过感应信号偏移及幅值归一化处理算法提高精度,在实验室搭建传感器样机,以高精度电控平移台进行测试。经测试,新型多周期双极电涡流直线位移传感器可以实现绝对位置测量,在0~60 mm量程内测量误差为30μm,最大非线性为0.08%。突破了传统多周期涡流式位移传感器绝对位置无法识别的局限。
