...Johannes Rosskopf; Christopher Kloth; Jens Dreyhaupt; Michael Braun; Bernd L. Schmitz; Tilmann Graeter Introduction: Cranial nonenhanced CT (NECT) imaging in hyperacute ischemic stroke is rarely used for assessing arterial obstruction of middle cerebral artery by identifying hyperdense artery sign...

..., the clinical meaning of changes in HV is yet to be clarified. Here, we investigated serial changes to HV in patients with AIS who received tissue plasminogen activator (t-PA) therapy. Methods: We studied t-PA patients presenting with HV on FLAIR in the middle cerebral artery territory. Patients underwent brain...

...Rieko Suzuki; Masatoshi Koga; Mayumi Mori; Kaoru Endo; Kazunori Toyoda; Kazuo Minematsu Background: Failure to detect the sphenoidal segment of the middle cerebral artery (M1) on transcranial color-coded sonography (TCCS) results from either M1 occlusion or an insufficient temporal bone window (TBW...

...Joanna M. Wardlaw; Fergus N. Doubal; Elizabeth Eadie; Francesca Chappell; Kirsten Shuler; Vera Cvoro Atheromatous middle cerebral artery (MCA) stenosis could cause lacunar stroke by occluding lenticulostriate artery origins, but atheroma is common, and previous studies lacked suitable controls. We...

...Chang-Woo Ryu; Geon-Ho Jahng; Eui-Jong Kim; Woo-Suk Choi; Dal-Mo Yang Background: Although black-blood MRI (BB-MRI) can identify plaques in the cervical carotid arteries, this modality has not been applied in intracranial arteries. We imaged the lumina and walls of stenotic middle cerebral arteries...

...Takeshi Iwanaga; Shuji Arakawa; Sasitorn Siritho; Greg Fitt; Helen M. Dewey; Brian R. Chambers; Geoffrey A. Donnan Background and Purpose: We have noted the presence of small strip-like infarcts involving the cortex within the interdivisional territory of the middle cerebral artery (MCA...

...Bong-Su Kang; Hyung-Min Kwon; Wi-Sun Ryu; Yong-Seok Lee Background: The annual risk of stroke or cardiovascular events has been reported to be over 10% in middle cerebral artery stenosis. However, the prognosis of patients with middle cerebral artery occlusion (MCAO) remains unclear. We...

... of the middle cerebral artery (MCA) M1 segment compared with 3D time-of-flight magnetic resonance angiography (MRA) at 3 T. Methods: Because MRA is considered as a reliable noninvasive technique to depict the normal anatomy of the intracranial artery, we prospectively defined the course and the patterns...

...) based on stereological grid counting and a digital atlas of the middle cerebral artery (MCA) infarct territory. Methods: We tested the hypotheses that the stereological method increases the accuracy of infarct estimation and that the number of patients deemed eligible for thrombolysis is greater...

...Hai Wei Huang; Ming Hui Guo; Rui Jin Lin; Ya Li Chen; Qin Luo; Ying Zhang; Ka Sing Wong Backgrounds: Intracranial atherosclerosis is the commonest vascular lesion for ischemic stroke in Asians. Most research on risk factors for middle cerebral artery (MCA) stenosis has been conducted in symptomatic...

...A-Hyun Cho; Dong-Wha Kang; Sun U. Kwon; Jong S. Kim Background and Purpose: The ‘lacunar hypothesis’ has been challenged, since small (diameter <15 mm) subcortical infarcts can be produced by middle cerebral artery disease (MCAD) or cardioembolism (CE), while a larger infarct can occur without...

...Marek Humpich; Oliver C. Singer; Richard du Mesnil de Rochemont; Christian Foerch; Heiner Lanfermann; Tobias Neumann-Haefelin Background: To investigate the effect of early (<6 h) versus delayed (>6 h) recanalization on infarct pattern in acute middle cerebral artery (MCA) occlusion. Methods...

...Yi-Chun Chen; Sien-Tsong Chen; Chi-Jen Chen; Tsong-Hai Lee Background: Assess the accuracy of transcranial color-coded sonography (TCCS) for detecting middle cerebral artery (MCA) stem occlusion and compare it with cerebral angiography. Methods: This study enrolled a series of patients who received...

...Hon-Man Liu; Dar-Ming Lai; Yong-Kwang Tu; Yao-Hung Wang Background: We report a vascular abnormality of the middle cerebral artery (MCA) that has not been described in the literature before. Methods: Two patients (1 male and 1 female; age 44 and 67 years, respectively) were found to have a vascular...
