From our experiences on 3 operative cases of ruptured intracranial aneurysm, a subarachnoid hematoma in the prepontine cistern remains long time and influences on the occurrence of late spasm of the cerebral arteries. Computed tomography did not reveal the presence of blood clot in the prepontine cistern clear, and the condition in an early stage of subarachnoid hemorrhage was not always severe in 3 cases. The continuous drainage from the lateral ventricle or the subarachnoid cistern was set after the aneurysm was obliterated by surgery. Nevertheless the late spasm of the basilar artery had developed and massive blood clot in the prepontine cistern was found at autopsy in 3 cases. The pathological study of the pons indicated the findings affected by blood circulation disturbances. The blood clot in the prepontine cistern is required to remove but it is difficult to open the prepontine cistern wide and to remove blood clot completely though supra or infratentorial surgical approach is used, therefore the irrigation by the drains in the lateral ventricle and subarachnoid cistern is tried hard to wash away blood clot in the prepontine cistern during and after the operaiton.
