Dense middle cerebral artery sign: an indicator of poor outcome in middle cerebral artery area infarction.
نویسندگان
چکیده
Thirteen patients with a dense appearance of the horizontal part of the middle cerebral artery (MCA) "dense middle cerebral artery sign" in CT scans taken within 24 hours after onset of ischaemic stroke had considerably poorer prognosis than controls with stroke, but without the sign. A hyperdense appearance of the MCA is known to be associated with thromboembolism, but dense middle cerebral artery sign is also an early warning of a large infarction, brain oedema and poor prognosis in infarction in the MCA area.

The hyperdense middle cerebral artery sign is a CT predictor of the development of a large cerebral infarct. The limits of detectability were tested in a blinded, then unblinded analysis of CT scans from 25 acute stroke patients. In the initial blinded analysis, sign detection exhibited the following mean values: sensitivity, 78.5%; specificity, 93.4%; positive predictive value, 66%; negative p...

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...

متن کاملAn Illustrative Case of Hyperdense Middle Cerebral Artery Sign
The management of ischemic stroke has improved greatly over the past two decades in terms of stroke treatment and there is strong evidence that outcomes after stroke can be improved and that death or disability from stroke can be reduced with appropriate treatment. However, in some cases where infarction involves the entire middle cerebral artery (MCA) territory can cause “malignant” MCA infarc...
