[Study of ruptured intracranial aneurysms with intracerebral hematomas--with special reference to operative...

We reviewed 40 cases of intracranial ruptured aneurysm with intracerebral hematoma (An-ICH) and compared those with 177 cases of intracranial single ruptured aneurysm causing only subarachnoid hemorrhage (An-SAH). An-ICH accounted 11.6% of the intracranial aneurysm, ruptured at the mean age of 54 years, and occurred equally in both sexes. The localization of An-ICH was 50% in the middle cerebral artery (MC), 43% in the anterior cerebral artery (AC) and 8% in the internal carotid arterial region. Forty percent of An-ICH were treated conservatively and the outcome was very misery (no useful life and 94% was poor or dead). Sixty percent of An-ICH were treated surgically (neck-clipping and removal of the hematoma) and the outcome was poor (17% useful life and 46% poor and dead). Especially in MC aneurysm, operability was 85% and post-operative useful life was 12% and post-operative poor or dead was 53%. In AC aneurysm, operability was 35% and post-operative useful life was 33% and poor or dead was 33%. These miserable results raised a question of operative indication for An-ICH. The five clinical indices (decerebration, hypertension greater than or equal to 200 mmHg, Hunt-Hess grade V, anisocoria in AC, severe shift of midline structure on X-CT) were selected, because any patients who presented with even only one of them became fatal or vegetative state regardless of conservative or surgical treatment. Assuming them as the non-operative standards, operability decreased in 35% MC, 29% AC, useful life outcome came up to 20% MC, 40% AC, and misery outcome came down to 20% MC, 20% AC.(ABSTRACT TRUNCATED AT 250 WORDS)
