摘要: 目的 通过研究急性脑梗死后交叉性小脑神经机能联系不能(CCD)的发生与幕上梗死灶的体积及位置的关系,探讨急性脑梗死后交叉性小脑神经机能联系不能发生的影响因素。方法 收集100例单侧幕上急性脑梗死患者的影像学资料,利用动脉自旋标记(ASL)成像技术测量双侧小脑半球脑血流量(CBF),根据脑血流量不对称指数分为CCD阳性组和CCD阴性组,分析两组中幕上梗死灶体积、位置与CCD发生的关系。结果 幕上梗死灶体积CCD阳性组的中位体积是3.60 cm3,CCD阴性组的中位体积是1.90 cm3,采用Mann-Whitney U检验,两组间的幕上梗死灶体积差异无统计学意义(P=0.052);幕上梗死灶位置为大脑前动脉供血区2例、大脑中动脉供血区35例、大脑后动脉4例、分水岭梗死59例,不同位置之间CCD的发生差异无统计学意义(P=0.762)。结论 急性脑梗死后可导致CCD现象的发生,大脑中动脉供血区CCD发生率最高,其次为分水岭区;幕上梗死灶体积大小对CCD发生率无影响。

Abstract: Objective: To study the relationship between the occurrence of crossed cerebellar diaschisis (CCD) with acute cerebral infarction and the supratentorial infarction volume and position, and to explore the influence factors the occurrence of crossed cerebellar diaschisis after acute cerebral infarction. Methods: The imaging data of 100 patients with unilateral supratentorial acute cerebral infarction were collected. Cerebral blood flow (CBF) of bilateral cerebellar hemisphere was measured by arterial spin labeling (ASL) imaging technology. According to the asymmetry index of cerebral blood flow, the patients were divided into the CCD positive group and the CCD negative group. The relationship between the supratentorial infarction volume and position and CCD was analyzed. Results: Mann-Whitney U test was used to compare the difference between the CCD-positive group and the CCD-negative group. It was found that the median volume of supratentorial infarction was 3.60 cm3 in the CCD-positive group and 1.90 cm3 in the CCD-negative group. There was no significant difference in the volume of supratentorial infarction between the two groups (P=0.052). There was no significant difference in the occurrence of CCD in different position (P=0.762). Conclusion: Acute cerebral infarction can lead to the occurrence of CCD. The incidence of CCD in the middle cerebral artery is the highest, followed by the watershed area, and there is no significant difference in the size of supratentorial infarction.
