BACKGROUND AND PURPOSE The goal of this study was to determine the alterations in vascular reactivity of human basilar artery after subarachnoid hemorrhage. METHODS Human basilar arteries were obtained from subjects who died within 1 day after subarachnoid hemorrhage and control subjects who died from causes other than brain involvement. Basilar artery strips were suspended for isometric tens...

Proven effective therapy to prevent ischemic deficits and other complications after subarachnoid hemorrhage is lacking despite extensive research efforts. A literature review documented both clinical and experimental evidence suggesting that heparin may be effective in preventing ischemic deficits after subarachnoid hemorrhage by reversing vasospasm, improving blood flow through narrowed vessel...

An intracranial saccular aneurysm is uncommonly diagnosed in a patient with closed head trauma. We herein present a patient with delayed rebleeding of a cerebral aneurysm misdiagnosed as traumatic subarachnoid hemorrhage (SAH). A 26-year-old female visited our emergency department because of headache after a motorcycle accident. Brain computed tomography (CT) showed a right-side dominant SAH in...

The Authors Reply: We agree with Finucane that it is important to monitor and treat hyponatremia after a ruptured cerebral aneurysm. He cites a study that showed fewer instances of hyponatremia among patients with spontaneous subarachnoid hemorrhage who were treated conservatively than among those who were treated with clipping or coiling.1 The group treated conservatively, however, consisted m...

INTRODUCTION Spinal subarachnoid hemorrhage has many causes including trauma, vascular malformations, aneurysms, spinal cord tumors, coagulation abnormalities, use of anticoagulants, systemic lupus erythematosus, or Behçet's disease. We report on a rare case of a spontaneous spinal subarachnoid hemorrhage after severe coughing of unknown origin. To the best of our knowledge, this is the first r...

BACKGROUND Subarachnoid hemorrhage is a common and dangerous disease with an unfavorable prognosis. Patients with poor-grade subarachnoid hemorrhage (Hunt & Hess Grades 4-5) are unconscious on admission. Because of the high mortality and disability rate associated with poor-grade subarachnoid hemorrhage, it is often treated conservatively. Timing of surgery for poor-grade aneurysmal subarachnoi...

Coagulation A bnormalities in Subarachnoid Hemorrhage • Coagulation and fibrinolytic studies were performed in 30 subarachnoid hemorrhage patients and 30 age-matched and sex-matched controls. Systemic abnormalities were detected in the following tests: recalcification time, fibrinogen, partial thromboplastin time, K value of thromboelastogram and euglobulin lysis time. The data suggest that sub...

Background: Targeted temperature management is a treatment strategy to lower core body achieve neuroprotection or reduce elevated intracranial pressure. Therefore, it has been increasingly used in the neurointensive care unit manage various types of acute neurologic injuries.Current Concepts: can be divided into three distinct phases, including induction, maintenance, and rewarming, each phase ...

BACKGROUND AND PURPOSE Extension of hemorrhage into the subarachnoid space is observed in primary intracerebral hemorrhage (ICH), yet the phenomenon has undergone limited study and is of unknown significance. The objective of this study is to evaluate the incidence, characteristics, and clinical consequences of subarachnoid hemorrhage extension (SAHE) in ICH on functional outcomes. METHODS Pa...
