The volume of an intracerebral hemorrhage has been shown to be an important independent predictor of mortality in several reports. A technique for estimating hematoma volume, known as the ABC/2 method, has been proven a reliable, simple bedside technique for the volume measurement of intraparenchymal intracerebral hemorrhage. Subdural hematomas also carry a significant mortality risk but are more amenable to surgical evacuation. A reliable, simple bedside measurement of subdural hematoma volume may prove a valuable tool in prognostication and management of patients with this entity.
Computed tomographic (CT) brain scans of 244 patients suffering from intracranial hemorrhage in the GUSTO-1 trial were systematically reviewed. The volumes of 298 intraparenchymal hematomas were measured by the ABC/2 technique, and the volumes of 44 subdural hematomas were measured by an adaptation of this technique and compared to computer-assisted volumetric analysis.
Excellent correlation between the techniques were achieved for both subdural (r=0.842; slope, 0.982) and intraparenchymal hematoma volume measurements (r=0.929; slope, 1.11).
The ABC/2 method is a simple and accurate technique for the measurement of intraparenchymal hematoma volume, and a simple adaptation allows for a similarly accurate measurement of subdural hematoma volume as well.
在多篇报道中，脑出血体积已被证明是死亡率的重要独立预测因素。一种估计血肿体积的技术，即ABC/2法，已被证实是一种可靠、简便的床旁技术，用于测量脑实质内脑出血的体积。硬膜下血肿也具有显著的死亡风险，但更适合手术清除。可靠、简便的床旁测量硬膜下血肿体积可能是预测和管理此类患者的一项有价值的工具。
对GUSTO-1试验中244例颅内出血患者的脑部计算机断层扫描（CT）进行系统回顾。采用ABC/2技术测量298例脑实质内血肿的体积，采用该技术的改良方法测量44例硬膜下血肿的体积，并与计算机辅助容积分析进行比较。
硬膜下血肿（r=0.842；斜率，0.982）和脑实质内血肿体积测量（r=0.929；斜率，1.11）在两种技术之间均取得了极好的相关性。
ABC/2法是一种简单、准确的测量脑实质内血肿体积的技术，简单的改良也能同样准确地测量硬膜下血肿体积。
