A-mode of ultrasound sonography has been attempted for diagnostic purpose of cerebro-vascular disease in the 1960s.<BR>Recently. in the 1970s, the introduction of the CT scanner has allowed progress in the aspiration surgery via burr hole for hypertensive intracerebral hemorrhage. At the same time, it is looked again of usefullness of ultrasonotomography combined with aspiration technique. Hematoma aspiration under hand-controled ultrasound sonography seems to be available to remove the hematoma by observating the real-time change of picture on echogram. The correlation between aspiration rate, operative method, timing of operation and echographic findings was mentioned.<BR>The conclusion was obtained that hematoma aspiration under ultrasound guidance is considered beneficial to remove the hematoma with less brain damage. This method should be more widespread in surgery because of its accuracy and simplicity.
