Spontaneous dissection of the cervical internal carotid artery (sICAD) is mainly assessed with MRI and magnetic resonance angiography (MRA), which are not always at hand. In contrast, color duplex sonography (CDS) readily available. We undertook this prospective study to examine accuracy CDS diagnose sICAD in patients first territory ischemia.Consecutive stroke or transient ischemic attack retinal ischemia underwent clinical laboratory examinations, ECG, cerebral arteries, cranial computed tomography case attack, echocardiography 24-hour ECG selected cases. Patients were included, if they <65 years age, showed a probable (cervical stenosed occluded), had no determined etiology ischemia. All included MRA+/-cerebral catheter angiography. The sonographer was blinded results studies.We 177 1652 screened patients. Excluded (n=1475) > =65 old (n=818), another cause (n=1475), intracranial hemorrhage (n=58). diagnosed 77 patients, undetermined remaining 100 Cervical 74 sICAD; there 6 falsely positive 3 negative findings. Thus, sensitivity, specificity, predictive values for diagnosis causing 96%, 94%, 92%, 97%, respectively.Color ultrasound allows reliable exclusion ischemia, whereas must be confirmed MRA.
