Anatomic and hemodynamic characterization of vertebral artery duplication via color doppler ultrasonography.

ABSTRACT:

Background and objectives

Vertebral artery (VA) duplication is an infrequent vascular variation with a dearth of information on hemodynamic parameters. In this study, color Doppler ultrasonography was utilized to evaluate the origins and hemodynamic features of VA duplication to offer a solid reference for clinicians who are endeavoring to gain insights into this particular form of vascular anomaly.

Methods

A retrospective analysis was conducted on patients with VA duplication detected by color Doppler ultrasonography. The analysis focused on the origins, the transverse course, diameter and the peak systolic velocity (PSV) of each segment of the duplicated VA.

Results

In the 36 branches in 18 subjecte identified as VA duplication, 27 branches originated from the subcl
