Unlabelled:
We observed 23 patients with clinical hypothesis of subarachnoidal hemorrhage (SAH) having cranial tomography (CT) without bleeding signals. The final diagnosis of SAH was made upon the cerebrospinal fluid (CSF) results. Twenty cases were submitted to brain angiography. They were focused under the clinical classification of Hunt & Hess. The main results were 1) 1/3 of patients had interval time between 24 and 48 hours after ictus and before CT and CSF making; this was the most sensitive CT time; 2) 55% of patients with brain angiography had aneurysm predominantly in the carotid and anterior cerebral artery territory; 3) the dominant clinical degree was Hunt & Hess I e II.
Conclusion:
the results demonstrate the need of CSF test in case of SAH clinical diagnosis with CT showing no bleeding signals.
