CONTRaLaTERaL aRTERiaL FLOWs iNTERaCTiON bY REFERENCE TO DOPPLER ULTRASONOGRAPHY

Abstract

Objective: This research paper discusses the phenomenon of junction and interaction of contralateral arterial flows in studies of various human vessels. Materials and methods. The studies enrolled 2236 healthy patients. Doppler ultrasonography was used to estimate the blood flow in brachial artery (before and after tourniquet application). The contralateral arterial flows were also studied in major vessels. Results. In the course of this research, the multidirectional blood flow consistent with junction and interaction of contralateral arterial flows was revealed. Values of maximum velocity for orthograde and contralateral blood flows before and after tourniquet application differed significantly (p < 0.05). Orthograde arterial flow was indicative of systolic peaks above the baseline. Contralateral arterial flow revealed systolic peaks below the baseline. Conclusions. The phenomenon under study is of practical bearing for diagnosing various diffuse and local vascular pathologies. Contribution. The outcome of this research will contribute to quality improvement in pathology diagnostics.
