Summary: | Tortuous brachiocephalic artery may lead to procedural difficulties among patients undergoing right transradial cardiac catheterization. By prospectively identifying patients with this anatomic barrier, operators may choose an alternate catheterization site to avoid complications from switching midway. To assess brachiocephalic artery tortuosity, 23 patients who underwent challenging diagnostic coronary angiography by right transradial access were compared to a control group of 29 patients who lacked brachiocephalic artery tortuosity. Preprocedural, plain chest x-rays were analyzed for measurable anatomic parameters and assessed for statistical significance between groups. The vertebrocarinal distance—the distance in centimeters between the spinous process of the first thoracic vertebra (T1) and the most caudal point of tracheal bifurcation, measured at and parallel to the midline—was the most reliable and statistically significant radiographic predictor of brachiocephalic artery tortuosity. Using this novel concept reduces procedure duration and radiation exposure by decreasing transradial cardiac catheterization failure rates. |
