Neuropathology of brain death in the modern transplant era. A recent editorial published in Stroke addressed the question of whether LP is necessary in patients with suspected SAH who are CT-negative within six hours of headache onset. Hematoma expansion commonly continues for 24 hours after symptom onset because of ongoing hemorrhage from the primary source, as well as vessel disruption and surrounding coagulopathy. The epidemiology of spontaneous SAH is hard to establish because of variations in its presentation in patients of differing ethnicities and gender. The emergency physician almost exclusively will be the first doctor to lay eyes and hands on these patients. All brains were free of intracranial hematoma or hydrocephalus. He currently has NIH funding investigating the correlation of inflammation and coagulation on the clinical outcome of patients after subarachnoid hemorrhage.
Patients with poor-grade aneurysmal subarachnoid hemorrhage (SAH) are However, the mechanism(s) and pathology responsible for their high within 3 days of admission and who did not receive respiratory assistance. The term subarachnoid hemorrhage (SAH) refers to extravasation of blood into the subarachnoid space between the pial Pathophysiology.

Finding an aneurysm in a patient with high pretest probability of SAH should elicit consultation with neurosurgery. Sign Up.
Roughly 27, to 30, cases of SAH are seen annually, making this a not-uncommon event, but one hidden among a vast number of headaches, most of which are benign. Although seizures are seen in up to one-fourth of patients presenting with SAH, routine use of antiepileptic medications has questionable benefit.
The risk of fever is increased in patients who have a larger hematoma size and in those with intraventricular extension. As the population continues to age, the increased use of anticoagulants and antiplatelet agents is associated with increased risk for spontaneous SAH.
