INTRODUCTION To assess the value of optic nerve sheath diameter (ONSD) measurements at different time points to predict the malignant evolution in middle cerebral artery (MCA) infarction and to investigate the relationship between ONSD and infarct volume on follow-up computed tomography (CT). METHODS In a single-center prospective observational study, we recruited patients with MCA infarction and age- and sex-matched controls. Clinical characteristics including NationaI Institutes of Health Stroke Scale (NIHSS) and ONSD measurement were assessed during the first five days after symptom onset. Volumetric analysis of the infarction was performed by a neuroradiologist, who was blinded to results of ONSD measurement and clinical examinations, based on CT scans. RESULTS We enrolled 29 patients with MCA infarction, including 10 with malignant MCA (mMCA) infarction and 14 controls. Mean ONSD on admission was already larger in patients who had developed an mMCA (5.99 ± 0.32 mm) compared to patients with MCA infarction (4.98 ± 0.53 mm; P = 0.003), and to control patients (4.57 ± 0.29 mm; P < 0.001). Correlation was observed between the ONSD mean value bilateral measures per individual and volumetric evaluation of cerebral infarction in the CT scan after one day (r = 0.623; P = 0.002). An ONSD value of 5.6 mm predicted an mMCA with a sensitivity of 100% and specificity of 90% yielding a positive predictive value of 83% and negative predictive value of 100%. CONCLUSIONS ONSD measurement might be accurate for the noninvasive detection of increased ICP and for the recognition of patients being likely to develop mMCA.

视神经鞘管直径的超声检查可确定患有恶性病风险的大脑中动脉梗塞的患者:一项前瞻性前瞻性观察性研究。

简介为了评估在不同时间点的视神经鞘管直径(ONSD)测量值,以预测大脑中动脉(MCA)梗死的恶性演变,并研究随访计算机断层扫描(CT)上ONSD与梗死体积之间的关系。 。方法在一项单中心前瞻性观察性研究中,我们招募了MCA梗塞以及年龄和性别匹配的对照患者。在症状发作后的前五天内评估了包括美国国立卫生研究院卒中量表(NIHSS)和ONSD测量在内的临床特征。由神经放射科医生对梗塞进行体积分析,他不知道ONSD测量结果和基于CT扫描的临床检查结果。结果我们招募了29例MCA梗死患者,包括10例恶性MCA(mMCA)梗塞和14例对照。发生mMCA的患者(5.99±0.32 mm)与MCA梗死的患者(4.98±0.53 mm; P = 0.003)和对照患者(4.57±0.29 mm; P <0.001)相比,入院时的平均ONSD已经更大。 )。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。发生mMCA的患者(5.99±0.32 mm)与MCA梗死的患者(4.98±0.53 mm; P = 0.003)和对照患者(4.57±0.29 mm; P <0.001)相比,入院时的平均ONSD已经更大。 )。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。发生mMCA的患者(5.99±0.32 mm)与MCA梗死的患者(4.98±0.53 mm; P = 0.003)和对照患者(4.57±0.29 mm; P <0.001)相比,入院时的平均ONSD已经更大。 )。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。相较于MCA梗死患者(32 mm)(4.98±0.53 mm; P = 0.003)和对照组患者(4.57±0.29 mm; P <0.001)。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。相较于MCA梗死患者(32 mm)(4.98±0.53 mm; P = 0.003)和对照组患者(4.57±0.29 mm; P <0.001)。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。在一天后的CT扫描中观察到每个人的ONSD平均值双侧测量值与脑梗死体积评估之间的相关性(r = 0.623; P = 0.002)。5.6 mm的ONSD值预测mMCA的敏感性为100%,特异性为90%,产生的阳性预测值为83%,阴性预测值为100%。结论ONSD测量对于无创检测ICP升高和识别可能发展为mMCA的患者可能是准确的。
