[Stereotactic aspiration using coordinate software for hypertensive intracerebral hematomas]

Abstract

Stereotactic aspiration for intracerebral hematoma has become widely used due to improvements in computed tomography (CT). CT-guided stereotactic aspiration for hypertensive intracranial hematomas was performed in 46 cases. Stereotactic aspiration with coordinate software was carried out among 16 cases. We compared the clinical results of conventional stereotactic aspiration with results of the new method using coordinate software. Using coordinate software, we can examine the route for the target point, as well as the target point of the hematoma before surgery. Therefore we can avoid obstacles such as ventricles and internal capsules. Further, we can aspirate hematoma by using only this one procedure. Mean hematoma aspiration percentage has risen from 44.9 to 87.2% by using coordinate software. Rate of drainage tube insertion after operation has decreased from 90 to 50%. The period of placement of the drainage tube and the frequency of infection due to the drainage tube has become lower, too. Therefore we can say that the outcome of treatment of hypertensive intracranial hematomas is improved by using coordinate software.
