Hemifacial spasm caused by a spontaneous dissecting aneurysm of the vertebral artery. Case report.

abstract：OBJECT:Studies on risk factors for subarachnoid hemorrhage (SAH) show heterogeneity. For example, hypertension has been found to be a significant risk factor in some studies but not in others. The authors hypothesized that differences in the ethnicity of the populations studied could account for these findings. METHOD...
