Intracerebral or parenchymal arterioles play an important role in the regulation of both global and regional blood flow within the brain. Brain cortex lacks significant collateral sources of blood and thus is at risk if blood flow through p...
Subarachnoid blood converts neurally evoked vasodilation to vasoconstriction in rat brain cortex [0.03%]

The matching of blood flow to regional brain function, called functional hyperemia or neurovascular coupling, involves the coordinated activity of neurons, astrocytes, and parenchymal arterioles. Under physiological conditions, localized ne...

Injury depolarizations akin to spreading depression of Leão are important in the progression of tissue damage in ischemic stroke, intracranial hemorrhage, and trauma. Much of the research on injury depolarizations has been focused on their...
Criteria for the diagnosis of noninfectious and infectious complications after aneurysmal subarachnoid hemorrhage in DISCHARGE-1 [0.03%]

Patients with aneurysmal subarachnoid hemorrhage (aSAH) frequently develop secondary noninfectious and infectious complications that have an important impact on clinical course and outcome. We here report on criteria for the diagnosis of th...
Evaluation of intracranial electrocorticography recording strips and tissue partial pressure of oxygen and temperature probes for radio-frequency-induced heating [0.03%]

Spreading depolarization and subsequent cortical spreading ischemia have been recognized as new mechanisms of ischemic damage in patients with subarachnoid hemorrhage. We are investigating these mechanisms using intracranial implanted devic...
Cerebral glucose and spreading depolarization in patients with aneurysmal subarachnoid hemorrhage [0.03%]

The pathogenesis of delayed cerebral ischemia (DCI) is multifactorial and not completely elucidated. Our objective was to determine if episodes of spreading depolarization (SD) are reflected in compromised levels of extracellular glucose mo...
Full-band electrocorticography of spreading depolarizations in patients with aneurysmal subarachnoid hemorrhage [0.03%]

Cortical spreading depolarizations (CSDs) are a pathologic mechanism occurring in patients with aneurysmal subarachnoid hemorrhage and may contribute to delayed cerebral ischemia. We conducted a pilot study to determine the durations of dep...

Spreading depolarization (SD) is a wave of mass neuronal and glial depolarization associated with net influx of cations and water. Prolonged SDs facilitate neuronal death. SD induces tone alterations in cerebral resistance arterioles, leadi...
Computerized occlusion rating of embolized ruptured intracranial aneurysms: relation to intra- and postinterventional aneurysm rehemorrhage [0.03%]

Endovascular coil occlusion of ruptured cerebral aneurysms has a higher rate of rebleeding compared to surgical clipping. Initial aneurysm coil occlusion rate (OR) is the strongest available predictor of aneurysm rebleeding. Standard clinic...

The use of intraoperative digital substraction angiography (iDSA) is a tool in cerebrovascular surgery. According to recent studies, iDSA has been shown to alter surgical treatment in approximately 12% of cases. Moreover, it has been demons...
