acute stroke,

Acute occlusion of cervical or intracranial arteries is the most common cause of ischemic stroke (IS). The aims of the current study were to compare the occurrence of acute pathologic findings in intracranial arteries using transcranial color-coded sonography (TCCS) and computed tomographic angiography (CTA) performed within 3 hours of IS onset and to assess the correlation between the vascular findings on admission and the patient's clinical state on admission and 3 months after the IS. Forty-five consecutive patients with an acute IS were included in the prospective study during an 18-month period. All patients underwent CTA and TCCS within the first 3 hours of symptom onset. A high rate of pathologic findings in the intracranial circulation was found (70.9% in CTA and 77.4% in TCCS examinations). The CTA and TCCS findings with respect to the intracranial arteries ... ect.
