Comparative examination of the pulse of both right and left carotid arteries.
The technique of CRESG secured on both arteries simultaneously is applied as a noninvasive diagnostic tool. A group of 42 persons (healthy and patients, 7 females and 35 males) aged 19--66 years was examined. In 14 of them X-ray angiography and in 5 of these 14 cases the additional surgical procedure confirmed the diagnosis. A difference of less than or equal to 10% between left and right upstroke time is shown in all subjects with decreased distensibility and signifies a generalized atherosclerotic process in all central arteries. Greater asymetry in bilateral CRESG is caused by a local more pronounced left/right arterial lesion. It is concluded that simultaneous left/right CRESG help to differentiate between generalized and localized arterial lesions.
