目的:通过分析颈动脉斑块64排CT血管成像特点,探讨不同类型颈动脉斑块与缺血性脑卒中的相关性。方法回顾分析60例缺血性脑卒中患者头颈部64排CT血管成像资料,轴位原始图像结合容积再现( VR)及曲面重建( CPR),观察颈动脉斑块的分布、性质及形态特征,测量颈动脉狭窄程度。结果60例缺血性脑卒中患者中,58例存在颈动脉斑块,共发现斑块228块,其中非钙化斑块43块,钙化斑块125块,混合斑块60块。60例患者中颈动脉出现轻度狭窄170处,中度狭窄20处,重度狭窄12处,闭塞1处,管腔未见明显狭窄20处。颈内动脉颅内段有5处钙化斑块,CT无法评价其狭窄程度。非腔隙性脑梗死与腔隙性脑梗死患者不稳定性斑块及稳定性斑块构成比差异有统计学意义( P<0.05及0.01)。结论64排CT血管成像能够准确判断颈动脉斑块的分布、性质、形态特征及颈动脉的狭窄程度,对缺血性脑卒中的预防、治疗及预后的判断具有重要价值。
目的:通過分析頸動脈斑塊64排CT血管成像特點,探討不同類型頸動脈斑塊與缺血性腦卒中的相關性。方法迴顧分析60例缺血性腦卒中患者頭頸部64排CT血管成像資料,軸位原始圖像結閤容積再現( VR)及麯麵重建( CPR),觀察頸動脈斑塊的分佈、性質及形態特徵,測量頸動脈狹窄程度。結果60例缺血性腦卒中患者中,58例存在頸動脈斑塊,共髮現斑塊228塊,其中非鈣化斑塊43塊,鈣化斑塊125塊,混閤斑塊60塊。60例患者中頸動脈齣現輕度狹窄170處,中度狹窄20處,重度狹窄12處,閉塞1處,管腔未見明顯狹窄20處。頸內動脈顱內段有5處鈣化斑塊,CT無法評價其狹窄程度。非腔隙性腦梗死與腔隙性腦梗死患者不穩定性斑塊及穩定性斑塊構成比差異有統計學意義( P<0.05及0.01)。結論64排CT血管成像能夠準確判斷頸動脈斑塊的分佈、性質、形態特徵及頸動脈的狹窄程度,對缺血性腦卒中的預防、治療及預後的判斷具有重要價值。

Objective To analysis 64-slice CT angiography imaging features of carotid atherosclerotic plaque and explore the relationship between different types of carotid atherosclerotic plaque and ischemic cerebral stroke. Methods The clinical data of 60 cases of ischemic cerebral stroke were retrospectively analyzed, all the cases were underwent 64-detector row CT angiography, and the distribution, character and morphological characteristics of carotid atherosclerotic plaque, and morphological characteristics and the extent of stenosis were observed with the original ax -ial image,volume rendering ( VR) and curved planar reconstruction ( CPR). Results In the 60 cases of ischemic cer-ebral stroke,58 cases with carotid atherosclerotic plaque were found. A total of 228 plaques were detected, including 43 non-calcified plaque, 125 calcified plaque and 60 mixed plaque. In 60 cases, 170 mild stenosis, 20 moderate ste-nosis, 12 severe stenosis and 1 occlusion were found, no significant stenosis were found in 20 sites. Five calcified plaques were found in intracranial segment of internal carotid artery, and CT can′t evaluate the severity of the steno-sis. There was significantly statistical difference in unstable plaque between non-lacunar infarct and lacunar infarct (P<0. 05 ). Conclusion 64-detector row CT angiography of carotid atherosclerotic plaques can accurately detect the dis -tribution, character and morphological characteristics of carotid atherosclerotic plaque and the degree of stenosis of ca -rotid artery,it is a valuable method in prevention, treatment, and prognosis judgement of ischemic cerebral stroke.
