چکیده

BACKGROUND AND PURPOSE Patients with large middle cerebral artery infarction and elevated intracranial pressure (ICP) who are undergoing invasive intensive care therapy require technical monitoring. However, the effectiveness of the current gold standard, measurement of ICP, is limited. Furthermore, the effects of what is considered to be standard antiedema medical treatment are not fully understood. We studied whether multimodal monitoring can help to overcome this problem. METHODS ICP, cerebral perfusion pressure (CPP), and partial brain tissue oxygen pressure (PbrO(2)) were continuously measured within the white matter of the frontal lobe unilaterally or bilaterally. We analyzed the effects of antiedema drugs and looked for pattern changes in the PbrO(2) before transtentorial herniation in patients in whom this could not be prevented. Furthermore, complications were registered. RESULTS We performed 27 measurements in 21 patients. A total of 297 antiedema drug administrations were analyzed in 11 patients. Hyper-HAES and mannitol were most often associated with an increase in CPP and PbrO(2), whereas the use of thiopental and tromethamine led to negative or contrary effects, although ICP was decreased in every case. Pattern changes in the PbrO(2) curve could be observed between 6 to 18 hours before transtentorial herniation. No bleeding complication or infections were observed. CONCLUSIONS Multimodal monitoring can be used to monitor antiedema drug effects. Our data suggest that with multimodal monitoring, pathophysiological changes could be predicted considerably in advance. ICP alone is of questionable use. Furthermore, this method might help to optimize the timing of invasive therapy in space-occupying infarction.

Investigate the effect of TRPV1 receptor antagonist (AMG9810) on stroke outcome in the permanent middle cerebral artery occlusion in male rat

Introduction: TRPV1 is a non-selective cation channel with high permeability to calcium ions, and is also involved in the development of neurogenic and inflammatory pain. The increase in intracellular calcium plays a role in worsening of stroke. In the present study we investigated the effect of (AMG9810) TRPV1 receptor antagonist on stroke outcome in the permanent middle cerebral artery occlus...

Pure sensory stroke caused by a small cortical infarct in the middle cerebral artery territory.

A patient with the sudden onset of a pure sensory deficit involving cortical modalities in his left hand and foot is described. CT scan suggested the lesion responsible for the deficit was a small cortical infarct in the middle cerebral artery territory, involving the middle part of the post-central gyrus and interrupting thalamo-cortical pathways in the corona radiata.

Posterior cerebral artery infarction from middle cerebral artery infarction.

BACKGROUND While it is known that posterior cerebral artery (PCA) infarction may simulate middle cerebral artery (MCA) infarction, the frequency and localization of this occurrence are unknown. OBJECTIVE To determine the frequency of PCA infarction mimicking MCA infarction and the territory of the PCA most commonly involved in this simulation. DESIGN We studied 202 patients with isolated in...

Occipital infarction with hemianopsia from carotid occlusive disease.

Extracranial internal carotid artery occlusive disease usually produces stroke in the middle cerebral artery territory or the border zone between the middle and anterior cerebral arteries. It is unusual for occipital infarction in the posterior cerebral artery territory to be caused by internal carotid artery disease despite the fact that the posterior cerebral artery may arise directly from th...

Topographical evaluation of aphasia based on brain vascular territories

Topographical evaluation of aphasic brain lesions can enhance our knowledge of cognitive physiology and plasticity. This prospective study was conducted on 100 stroke-afflicted patients with aphasia admitted in Valie-Asr Hospital (Khorasan, Iran) in 2003. Topography of infarct lesions was detected by a neurologist based on the map of brain vascular territories in CT-scan. Aphasic lesions catego...
