BACKGROUND AND PURPOSE
Transcranial color-coded duplex sonography (TCCS) is a useful tool for evaluating cerebral structures. The aim of this study was to examine whether TCCS is useful for evaluation of hematoma volume.
METHODS
Patients with supratentorial intracranial hemorrhage within 24 hours of onset were enrolled. We measured major longitudinal, sagittal in axial plane, and coronal diameter of hematoma on computed tomography (CT) and on TCCS. We estimated hematoma volume using the formula, V = longitudinal × sagittal × coronal/2. The correlation between the hematoma volume on TCCS and CT was studied.
RESULTS
Of 48 patients with acute supratentorial cerebral hemorrhage admitted to our hospital, 20 patients with temporal windows (age, 67.5 ± 14.8 years; male, 15) were enrolled. A good correlation was found between TCCS and CT for longitudinal, sagittal, coronal diameter, and hematoma volume (r= .907, P < .0001; r= .811, P < .0001; r= .595, P= .0056; and r= .856, P < .0001). Bland-Altman test showed a good agreement between CT and TCCS, the mean difference between both methods was .31.
CONCLUSION
TCCS appears to be a useful method for evaluating hematoma volume.
背景与目的
经颅彩色双功能超声（TCCS）是评估脑结构的有用工具。本研究旨在探讨 TCCS 是否有助于评估血肿量。
方法
纳入发病 24 小时内幕上颅内出血的患者。我们在 CT 和 TCCS 上测量血肿的主要长轴、矢状轴和冠状轴直径。我们使用公式 V = 长轴×矢状轴×冠状轴/2 来估计血肿量。研究了 TCCS 上血肿量与 CT 的相关性。
结果
我院收治的 48 例急性幕上脑出血患者中，有 20 例颞窗患者（年龄 67.5 ± 14.8 岁；男性 15 例）纳入本研究。TCCS 与 CT 之间在长轴、矢状轴、冠状轴直径和血肿量上均有良好的相关性（r=.907，P <.0001；r=.811，P <.0001；r=.595，P=.0056；r=.856，P <.0001）。Bland-Altman 检验显示 CT 和 TCCS 之间具有良好的一致性，两种方法之间的平均差异为.31。
结论
TCCS 似乎是一种评估血肿量的有用方法。
