[Differential diagnostic criteria of subarachnoid hemorrhage in arterial and arteriovenous aneurysms].

The clinical manifestations of subarachnoidal hemorrhages were investigated in 115 patients with arterial and 32 ones with arteriovenous aneurysms. The patients' histories, their neurologic status, the clinical and laboratory findings obtained were correlated, enabling the authors to specify the picture of subarachnoidal hemorrhages due to some congenital vascular pathology.
