Hemodynamics of Poor-grade Subarachnoid Hemorrhage

ABSTRACT

Patients who are devastated neurologically or medically after aneurysmal subarachnoid hemorrhage(SAH) are described as 'poor grade' patients. More recent studies have documented that the initial hemorrhage is by far the most important determinant of outcome after aneurysmal subarachnoid hemorrhage. This review mainly includes hemodynamics and suspected mechanisms of acute brain injury after aneurysmal SAH, particularly in special reference to increased intracranial pressure and cerebral ischemia during and after SAH.
