Comparative StudyCranial computed tomography in subarachnoid hemorrhage: relationship between blood detected by CT and lumbar puncture.
We compared the results of cranial computed tomography (CT) and lumbar puncture (LP) in patients who had subarachnoid hemorrhage due to proven ruptured intracranial aneurysm. We found no correlation between the number of red blood cells in the cerebrospinal fluid collected by LP and the amount and extent of blood detected by CT.

The case of a patient who suffered a nontraumatic subarachnoid hemorrhage (SAH) associated with normal angiography is reported. Three weeks later he developed an embolic stroke secondary to a nonhemolytic Staphylococcus epidermidis endocarditis of the mitral valve; thus, the SAH was the initial manifestation of bacterial endocarditis. Bacterial endocarditis should be considered a possible cause of SAH, especially in the 7% of patients with angiographically negative SAH.

Comparative StudyPreoperative treatment of ruptured intracranial aneurysms with tranexamic acid and monitoring of fibrinolytic activity.
The fibrinolytic activity in cerebrospinal fluid has been monitored by determination of levels of fibrin split products (FSP) in 23 patients with ruptured intracranial aneurysms. In 20 of these 23, FSP was found in the cerebrospinal fluid (CSF), with levels ranging from 10 to 80 micrograms/ml. ⋯ These results suggest that there exists a localized fibrinolytic activity, and monitoring the FSP levels in the CSF may be a simple and accurate method for controlling the efficiency of antifibrinolytic therapy. Thus, treatment could be begun with a lower dose, which could be increased later as deemed necessary from the results of careful monitoring.
