Abstract
This study was performed to clarify the prognostic value of common carotid hemodynamics in early-stage brain infarction.
A total of 39 patients comprising 28 males and 11 females aged 34 to 88 years (mean 69 years) were enrolled. All the patients were diagnosed as having atherothrombotic brain infarction or lacunar infarction on the basis of their clinical features and the findings of brain computed tomography. The patients were divided into 3 groups as follows: 31 patients who could walk with or without a stick (Group I), 4 who were confined to a wheelchair or bedridden (Group II), and 4 who died (Group III) . The common carotid hemodynamics were evaluated within 72 h and 1, 2, 3, and 4 weeks after onset using an ultrasonic quantitative flow measurement system. Common carotid hemodynamics were elucidated in terms of mean blood flow volume (BF) .
The mean blood flow volume at both the involved site and the opposite site within 72 h after onset was significantly decreased in Group III compared with that in Group I.
These results indicate that evaluation of common carotid hemodynamics in patients with early-stage brain infarction may be useful for estimating the prognosis of brain infarction.
