Key result
3D carotid reconstruction reveals tortuous geometry with a mean bifurcation angle of ~36 degrees.
Why the study?
Accurate characterization of carotid artery geometry is vital to understanding atherosclerosis pathogenesis, but mean carotid artery geometry has not been comprehensively characterized.
Population
16 male patients with severe carotid artery disease
Design
Observational study using computerized tomography angiography with semiautomated segmentation

Informs endovascular device design for tortuous carotid anatomy; leaves open validation in larger, diverse cohorts.
Observational (n=16)
The mean human carotid artery in patients with severe disease exhibits complex curvature, nonplanarity, and smaller bifurcation angles than typically reported, providing critical data for biomechanical modeling and endovascular device design.
Kamenskiy et al. (2012) conducted an observational in Severe carotid artery disease (n=16). Computerized tomography angiography and 3D reconstruction was evaluated on Mean carotid artery geometry including bifurcation and planarity angles, diameters, and cross-sectional areas. Three-dimensional reconstruction of the carotid artery in 16 male patients revealed a tortuous geometry with a mean bifurcation angle of 36±11 degrees and planarity angle of 11±10 degrees.
