| Abstract: | Authors are discussing dilemma about necessary diagnostic procedure in making decision for surgical treatment of the carotid disease. Attitudes are changing and the old opinion of the necessity for angiogram of extra cranial blood vessels is substituted by the opinion that CDS (Color Duplex Scan) is satisfactory in the majority of cases to indicate of the surgical treatment. Comparing the invasive and noninvasive diagnostic's with operative findings, authors empirically confirm the given hypotheses, looking back to the cases where angiogram is necessary. The following issues were discussed: Estimate of the locaton of maximal shrinking, degree of shrinking, length of shrinking and characteristics of plaque as the most important parameters for indication and operative tactics. Diagnostics with CDS is shown as reliable with high degree of matching with operative findings. |
