| 目的 探讨颈动脉斑块CEUS增强特征与脑梗死之间的关系。方法 以彩色多普勒超声观察136例患者有无颈动脉斑块。将颈动脉斑块CEUS增强特征分为3级:无增强(1级)、基底部增强(2级)和中心部增强(3级)。比较脑梗死和无脑梗死患者颈动脉斑块CEUS增强特征,随访观察各级增强颈动脉斑块患者中的新发脑梗死病例比例。结果 近期脑梗死同侧颈动脉斑块出现2级、3级增强者分别占30.77%(16/52)和40.38%(21/52),陈旧性脑梗死为28.00%(21/75)和21.33%(16/75),无脑梗死患者为24.03%(31/129)和8.53%(11/129),三者比较差异有统计学意义(χ2=31.56,P<0.01)。随访发现,1、2、3级增强斑块,同侧大脑半球新发脑梗死比例分别为1.47%(2/136)、8.93%(5/56)和7.14%(3/42),差异有统计学意义(P<0.05)。结论 颈动脉斑块CEUS增强特征与脑梗死关系密切。 |

| Objective To investigate the correlation of carotid plaques characteristics detected by contrast enhanced ultrasound (CEUS) with brain infarction. Methods Carotid atherosclerosis plaques of 136 patients were imaged with CEUS. Contrast enhancement within plaques were categorized as absent (grade 1), peripheral (grade 2) and extensive internal (grade 3). The patients were followed up for stroke occurrence. Results Recent brain infarction patients had higher degree of plaques enhancement which were 30.77% (16/52) in grade 2 and 40.38% (21/52) in grade 3, while old brain infarction had 28.00% (21/75) in grade 2 and 21.33% (16/75) in grade 3, respectively, and patients without brain infarction had 24.03% (31/129) in grade 2 and 8.53% (11/129) in grade 3 (χ2=31.56, P<0.01). Stroke occurrence ratio was 8.93% (5/56) in patients with grade 2 enhancement plaques and 7.14% (3/42) in patients with grade 3 enhancement plaques, both higher than that of patients with no plaques enhancement (2/136, 1.47%, P<0.05). Conclusion Carotid plaques contrast enhancement have significant correlation with brain infarction. |
