title: [Subarachnoid hemorrhage of unknown etiology: management, prognosis, and predictive factors].
abstract: Thirty-nine consecutive patients with subarachnoid hemorrhage (SAH) of unknown etiology were studied retrospectively. A significant relationship between arterial hypertension, blood on CT and angiographic spasm was found. The use of nimodipine was associated with a reduction of vasospasm. Antifibrinolytic agents did not increase the risk of ischemic complications. The prognosis was generally favorable.
