Radial Artery - Caliber and Course Cardiologist's Perspective

Background – Knowledge of radial artery anomalies and caliber is of importance for interventional cardiologists to plan their therapeutic procedures.
Materials & methods -To conduct a descriptive study on radial artery, in relation to level of origin, length and diameter at origin, midway point, wrist and anatomical snuff box.
Results – Average values- Right - distance of bifurcation below the line joining the two epicondyles of humerus-3.31±1.04cms, length -74±1.91cms, diameter at origin - 2.19±0.55mms, midway- 1.98±0.53mms, wrist-1.96±0.58mms, anatomical snuff box- 1.83±0.62mms with one anomalous high origin. Left –bifurcation- 2.88±1.13cms below, length- 22.69±2.02cms, diameter at origin-2.17±0.73mms, midway-1.99±0.83mms, wrist-1.99±0.82mms, anatomical snuff box -1.87±0.75mms.
Conclusion – There were significant differences with regard to diameter on right side at origin and anatomical snuff box and also in ethnicity.
