Differentiation of early subarachnoid hemorrhage from traumatic lumbar puncture.

Differentiation between traumatic tap and aneurysmal subarachnoid hemorrhage: prospective cohort study

OBJECTIVES To describe the findings in cerebrospinal fluid from patients with acute headache that could distinguish subarachnoid hemorrhage from the effects of a traumatic lumbar puncture. DESIGN A substudy of a prospective multicenter cohort study. SETTING 12 Canadian academic emergency departments, from November 2000 to December 2009. PARTICIPANTS Alert patients aged over 15 with an acu...

Fluoroscopy-guided lumbar puncture: decreased frequency of traumatic tap and implications for the assessment of CT-negative acute subarachnoid hemorrhage.

BACKGROUND AND PURPOSE In patients with suspected subarachnoid hemorrhage (SAH) and negative CT findings, the iatrogenic introduction of RBCs into the CSF during lumbar puncture may lead to a misdiagnosis. We tested the hypothesis that the risk of traumatic lumbar puncture is lower with the fluoroscopy-guided technique than with the standard bedside technique. METHODS Data were collected retr...

Lumbar puncture and subarachnoid haemorrhage.

Medical notes of 123 patients with subarachnoid haemorrhage were examined. No patient deteriorated at the time of lumbar puncture. All but 2 patients with associated intracerebral haematomas had markedly impaired consciousness or focal signs. Two of 30 patients with meningitis were initially diagnosed as subarachnoid haemorrhage, and one died without lumbar puncture. If consciousness is not mar...

Cerebral Angiographic Findings in Non-Traumatic Intracranial Hemorrhage: A Single Center Experience in the West of Iran

Background and Aim: This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial...
