Abstract

Abstract:

Objective To describe the incidence and distribution of vascular calcification in intracranial vertebral artery (IVA) and basilar artery (BA) on computed tomography angiography (CTA). Methods The data of hospitalized patients who received head and neck CTA examination in our hospital from February 2014 to October 2017 were consecutively collected. We reviewed all CTA to compare the differences of incidence of vascular calcification in IVA and BA, and the incidence of proximal and distal segment calcification in IVA and BA. Results A total of 93 patients were included in this study, with 64 males and 29 females. The mean age was (62.8±12.9) years. The mean age of vascular calcification group was significantly higher than that of no vascular calcification group [(68.8±10.4) vs (59.8±13.0) years, P =0.002]. IVA calcification was found in 31 (33.3%) patients, and BA calcification was also found in 5 (5.4%) patients among the 31 patients. Calcification only in BA was not found. After statistical analysis, it was found that the calcification incidence in IVA was significantly higher than that in BA (P =0.003). The calcification incidence at proximal segment of bilateral IVA was significantly higher than at distal segment of that (P =0.000), while the calcification between left and right IVA had no statistic difference. Conclusions The incidence of vascular calcification was significantly higher in IVA than that in BA. The calcification of IVA and BA were more common in proximal segments.

摘要：

目的比较颅内椎动脉与基底动脉血管钙化在计算机断层扫描血管成像（computed tomography angiography，CTA）上的发生率和分布特点。

方法连续收集2014年2月-2017年10月在本院住院并行头颈部CTA检查的患者资料，通过综合分析CTA影像资料，比较血管钙化在颅内椎动脉和基底动脉发生率的差异及其在近、远段发生率的差异。

结果共收集患者93例，其中男64例，女29例，平均年龄（62.8±12.9）岁。血管钙化组的平均年龄（68.8±10.4）岁，明显高于无血管钙化组的（59.8±13.0）岁（P =0.002）。31例（33.3%）颅内椎动脉血管钙化患者中，5例（5.4%）同时发现有基底动脉血管钙化，而未见基底动脉单独发生血管钙化。统计学检验结果显示，颅内椎动脉血管钙化的发生率显著高于基底动脉（P =0.003），且左、右两侧颅内椎动脉血管钙化在近段发生率均显著高于远段（P =0.000）；左、右两侧颅内椎动脉之间血管钙化差异无统计学意义。

结论颅内椎动脉血管钙化显著多于基底动脉，且颅内椎动脉和基底动脉的血管钙化均更常见于近段。
