Based on thrombus location and nature and anatomic features of aorta and cerebral arteries, we hypothesized that cardiogenic embolisms (CE) and aortogenic embolisms (AE) might have different right-left propensity and lesion patterns.
We retrospectively reviewed patients with acute ischemic stroke with high-risk CE sources or moderate-or-severe aortic atherosclerotic plaques on transesophageal echocardiography. Lesion side and patterns on diffusion-weighted imaging were compared between CE and AE.
CE was identified in 123 and AE in 63. In multivariate analysis, right-sided lesions and corticosubcortical infarcts were independently associated with CE, and left-sided lesions and pial infarcts were independently associated with AE.
CE and AE have different radiological characteristics, as shown by the right-left propensity and lesions patterns of cerebral infarcts.
基于血栓位置和性质以及主动脉和脑动脉的解剖学特征,我们推测心源性栓塞(CE)和主动脉源性栓塞(AE)可能具有不同的左右倾向和病变模式。
我们回顾性分析了经食管超声心动图检查显示有高风险 CE 源或中重度主动脉粥样硬化斑块的急性缺血性脑卒中患者。比较了 CE 和 AE 之间弥散加权成像上的病变侧和病变模式。
CE 组 123 例,AE 组 63 例。多变量分析显示,右侧病变和皮质下梗死与 CE 独立相关,左侧病变和软脑膜梗死与 AE 独立相关。
CE 和 AE 具有不同的影像学特征,表现为脑梗死的左右倾向和病变模式。
