Non-invasive ultrasonic biopsy in the classification of early arterial lesions and in the evaluation of the rate of progression of arteriosclerosis.
The evaluation of early arterial lesions and the follow-up of the progression of arteriosclerotic wall changes is possible with high resolution ultrasound. While dynamic (duplex scanning) data are suitable for the follow-up of advanced stenosis and plaques, the morphological evaluation performed using the technique of non-invasive ultrasonic biopsy may be used to follow-up early lesions and their progression. The data obtained by ultrasonic biopsy are related to the incidence of occult coronary ischemia and to the occurrence of cardiovascular events in 4 years. The rate of progression (ROP) to the next, more advanced UB class can be also evaluated by ultrasonic biopsy. It has been shown that in diabetic and hyperlipidemic subjects the ROP is higher. Also in interventional studies using lipid lowering agents (with a four-year follow-up) a reduction in ROP in treated asymptomatic hyperlipidemic subjects in comparison with controls has been documented. The combination of dynamic data and morphological data gives us a complete evaluation of the vascular system both for the assessment of single individuals and for large population studies.
