The transcranial doppler (T.C.D.) is a non-invasive technique useful for the evaluation of vasospasm and intracranial hypertension in patients with subarachnoid hemorrhage (S.A.H.). Eighteen patients with recent S.A.H. were studied by means of T.C.D. device: in 14 patients the source of bleeding was a ruptured aneurysm of the circle of Willis, while the remaining 4 presented a negative four-vessels angiography. All the patients were studied 5 and 10 days after the bleeding. Our data showed that the ultrasonographic demonstration of vasospasm and/or I.C.H. is clearly related to the clinical status of the patients. No significant T.C.D. difference was noticed between the "sine materia" S.A.H. patients and the ones with ruptured aneurysm.

Abstract
The transcranial doppler (T.C.D.) is a non-invasive technique useful for the evaluation of vasospasm and intracranial hypertension in patients with subarachnoid hemorrhage (S.A.H.). Eighteen patients with recent S.A.H. were studied by means of T.C.D. device: in 14 patients the source of bleeding was a ruptured aneurysm of the circle of Willis, while the remaining 4 presented a negative four-vessels angiography. All the patients were studied 5 and 10 days after the bleeding. Our data showed that the ultrasonographic demonstration of vasospasm and/or I.C.H. is clearly related to the clinical status of the patients. No significant T.C.D. difference was noticed between the "sine materia" S.A.H. patients and the ones with ruptured aneurysm.
