The authors have analyzed the clinical characteristics of vasospasm following subarachnoid hemorrhage (SAH) secondary to rupture of cerebral aneurysms in 110 cases that demonstrated vasospasm during their hospital stay. It was concluded that subarachnoid clot surrounding cerebral arteries is the most important factor for initiating vasospasm.
