【摘要】：目的探讨颈内动脉海绵窦水平段血管弯曲度和弯曲半径对新型编织型支架(LVIS支架)打开情况的影响。方法回顾性连续纳入2015年12月至2016年1月第二军医大学附属长海医院神经外科应用新型LVIS支架治疗且支架近端释放于海绵窦段水平段的31例宽颈动脉瘤患者,根据支架是否在第1次释放后,支架完全贴壁分为两组,打开良好组23例,打开不良组8例。比较两组血管弯曲度和弯曲半径的差异。结果打开良好组与打开不良组的血管弯曲度平均值分别为118°±23°和147°±19°,差异有统计学意义(P=0.028);两组血管弯曲半径平均值分别为(3.4±0.7)mm和(2.8±0.7)mm,差异有统计学意义(P=0.042)。支架打开不良组的平均血管弯曲度更大,平均血管弯曲半径更小。结论血管弯曲度大及血管弯曲半径小与LVIS支架释放过程中打开不良有关。支架置入前对血管弯曲度的评估有助于指导支架释放技术。
[Abstract]:Objective to investigate the effect of curvature and radius of horizontal segment of cavernous sinus of internal carotid artery on the opening of new woven stent (LVIS). Methods from December 2015 to January 2016, 31 patients with wide carotid aneurysms were treated with new LVIS stents and the stents were released from the proximal end of the stents to the horizontal segment of the cavernous sinus in the Department of Neurosurgery, Changhai Hospital affiliated to the second military Medical University. According to whether the stent was released at the first time, the stents were divided into two groups: good open group (23 cases) and bad open group (8 cases). The differences of curvature and radius of blood vessels between the two groups were compared. Results the mean values of vascular curvature were 118 掳卤23 掳and 147 掳卤19 掳in the good open group and the bad open group, respectively (P0. 028), and the mean curve radius of the two groups were (3.4 卤0.7) mm and (2.8 卤0.7) mm, respectively (P0. 042). The mean vascular curvature and mean radius of vascular curvature were larger and smaller in the group with poor stent opening. Conclusion the large curvature and small radius of vascular curvature are related to the poor opening of LVIS stent. The evaluation of vascular curvature before stent placement is helpful in guiding stent release techniques.
