Abstract
Noninvasive vascular studies of the upper extremity were compared with the accepted standards of arteriography and surgical exploration. Results of noninvasive vascular studies and 40 arteriograms in 37 patients revealed agreement in 95% of the cases. Further comparison between results of noninvasive studies and surgical findings in 17 patients revealed a correlation of 100%. Thus, findings from our noninvasive vascular studies agreed with arteriographic and surgical findings with respect to the type, location, and extent of disease in 97% of patients studied. We conclude that noninvasive studies of the upper extremity are accurate, safe, reproducible, inexpensive, and well tolerated by patients. Noninvasive vascular studies also provide information on vascular dynamics that is not available from routine arteriography.
