Abstract:
Objective:To systematically assess the value of 2 dimension color Doppler ultrasound(2D-CDUS) in diagnosis,surgical treatment and interventional therapy of carotid artery stenosis. Methods: Twenty seven carotid stenosis patients were examined before and after operation with 2D-CDUS. The morphology and hemodynamic of carotid artery were detected. Results: Pre-operative examination showed that there were 17 cases with stenosis degree being 50%-70%, 2 cases 71%-79%, 5 cases 80%-90%, 3 cases 90%-99%. Twelve cases were operated on with carotid endarterectomy(CEA), 15 cases with percutaneous transluminal angioplasty and stent(PTAS). After operation all the vessels with CEA were patent, colored well and blood velocity was close to normal. Residual intima was observed floating in the blood vessel in only one patient. In the patients treated by PTAS, the location and courser of the stents were normal,and the vessels were patent. Conclusion: 2D-CDUS is convenient to use and non-invasive, which can assess extracranial carotid stenosis accurately before operation, assess the curative effect and detect the complications after operation.
