| 中文摘要: |
| 本文观察脑梗塞患者41例, 均经CT定位诊断；分为非梗塞侧(第Ⅰ组, 31例), 梗塞侧(第Ⅱ组, 51例), 并与正常对照(第Ⅲ组, 65例).主要探讨颈内动脉、椎动脉颅外段硬化性病变及血流动力学情况与梗塞灶的关系。使用高分辨力彩色多普勒超声诊断仪检测颈部颈动脉。结果显示：脑梗塞两组颈动脉内径增宽；内膜-中层增厚；舒张期末流速、时间平均流速降低；阻力指数、搏动指数增高；斑块发现率、管腔狭窄率均明显增高。梗塞侧与非梗塞侧相比, 内膜-中层厚度、软斑块发现率前者略高于后者, 其余参数均无统计学差异。斑块及颈动脉狭窄与梗塞病灶无明显同侧关系。提示颈动脉硬化与脑梗塞有一定的关系, 但尚不能通过颅外颈动脉超声扫查对脑梗塞作出确切定位性评估。 |

| This article observed carotid arteries in 41 cases of hemispheric infarction which were dignosed by CT. The arteries were divided into two groups:groupⅠ(no infarction side,n=31),group Ⅱ(infarction side ,n=51).Normal control was group Ⅲ,(n=65).The relation between cervical carotid atherosclerosis,hemodynamics and hemispheric infarct lesion was analyzed with high resolution color Doppler ultrasound.The results indicated that the diameters of carotid significant enlarge,the intimal-medial thicken,the end-diastolic velocity (EDV) and the time average velocity (Vmean) decrease,the resistive index(RI)and pulsatility index(PI)increase,the incidence of plaque and stenosis are significant high both in groupⅠand group Ⅱ. Comparing with groupⅠ,only the intimal-medial thickness and incidence of soft plaque were a little higher in the group Ⅱ.The rest parameters all had not statistical significance. It suggested that cervical carotid atheroscleroses was associated with the incidence of hemispheric infarction but could not estimate the lesion locations of infarction by ultrasound.It has not been found that the ipsilateral relation between the plaque or/and stenosis of carotid arteries and hemispheric infarction. The soft plaques are unsteady and may lead to hemispheric infarction so it should highly be paid attention |
