Abstract:
Objective:To assess the value of Transcranial Two Dimensional Color Doppler Ultrasound(TC-2D-CDUS) in diagnosis of carotid artery stenosis and in follow-up study after surgical treatment.Methods: Thirteen patients with carotid artery stenosis, who were excluded from vertebral or intracranial diseases, were detected before and after operation with TC-2D-CDUS. Results: TC-2D-CDUS indicated that 2 patients' image were not satisfactory, and the blood velocity of middle cerebral artery (MCA) in the same side of lesion was lowered to different extents in the other 11 patients. The waveform was blunted in 3 patients with their systolic peak disappeared, acceleration time prolonged, and the direction of the anterior cerebral artery(ACA) in the same side inverted.After operation,TC-2D-CDUS indicated that MCA blood velocity and the direction of ACA were normal. The blood distribution was symmetric in bilateral brains. Conclusion: TC-2D-CDUS can provide intracranial hemodynamic information. It can be used in the follow-up study after operation,helping to make accurate judgement and discover complications.
