Spreading depolarization: a possible new culprit in the delayed cerebral ischemia of subarachnoid hemorrhage.
Aneurysmal subarachnoid hemorrhage (SAH) is a devastating disease with a high mortality and morbidity rate. Gradual improvements have been made in the reduction of mortality rates associated with the disease during the last 30 years. However, delayed cerebral ischemia (DCI), the major delayed complication of SAH, remains a significant contributor to mortality and morbidity despite substantial r...

متن کاملIschemia-induced spreading depolarization in the retina.
Cortical spreading depolarization is a metabolically costly phenomenon that affects the brain in both health and disease. Following severe stroke, subarachnoid hemorrhage, or traumatic brain injury, cortical spreading depolarization exacerbates tissue damage and enlarges infarct volumes. It is not known, however, whether spreading depolarization also occurs in the retina in vivo. We report now ...
متن کاملManagement of delayed cerebral ischemia after subarachnoid hemorrhage
For patients who survive the initial bleeding event of a ruptured brain aneurysm, delayed cerebral ischemia (DCI) is one of the most important causes of mortality and poor neurological outcome. New insights in the last decade have led to an important paradigm shift in the understanding of DCI pathogenesis. Large-vessel cerebral vasospasm has been challenged as the sole causal mechanism; new hyp...
متن کاملMagnetic Resonance Imaging and Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage
The prognosis of aneurysmal subarachnoid hemorrhage (aSAH) has improved during the past decades. However, a recent hospital-based study showed that 90-day case fatality is still 30%. Determinants of functional outcome after aSAH may include the severity of the initial hemorrhage, rebleeding of the aneurysm, and cerebral ischemia that can be distinguished into (1) acute ischemia at the time of b...
