Prognosis of intraventricular hemorrhage due to rupture of intracranial aneurysm

Abstract

The prognosis of intraventricular hemorrhage (IVH) from rupture of intracranial aneurysms was studied in 43 patients admitted to our institution and to Kaga Central Hospital between April 1984 and December 1987. The total number of aneurysmal subarachnoid hemorrhage (SAH) patients admitted during this period was 156, so that 28% of SAH patients had IVH. In this study, the patients were analyzed with respect to IVH grading, volumes of intraventricular and intracerebral hematoma, consciousness level, intracranial pressure (ICP), ventricular dilatation and age. The IVH resulted from aneurysmal rupture of the anterior communicating artery (48%), anterior cerebral artery (distal portion of the anterior communicating artery) (11%), internal carotid artery (21%), middle cerebral artery (25%), and vertebro-basilar artery (14%). The mortality rate in patients with IVH was 33%, a poorer rate than that in patients without IVH (25%). As for morbidity, 44% of the patients with IVH had no or moderate disability, whereas the other 23% had severe disability or were in a persistent vegetative state. On the other hand, there was no or only moderate disability in 63%, and severe disability or a persistent vegetative state in 12% of the patients without IVH.(ABSTRACT TRUNCATED AT 250 WORDS)
