Analysis of the Inner Diameter of the Distal Radial Artery and the Influencing Factors in Chinese Patients

In recent years, the clinical application of distal radial artery (DRA) approach in cardiovascular intervention has become more and more extensive. However, compared with CRA, the DRA is smaller, resulting in an increased proportion of patients requiring multiple punctures and a lower success rate of implantation. It has been found that the mismatch between artery sheath and vessel size is one of the independent risk factors for postoperative vascular approach complications. Therefore, assessing the size of the DRA before vascular intervention is extremely important to select suitable patients, improve the success rate of puncture, and reduce the complications associated with the approach There are still few large-sample studies to evaluate the size of DRA and its influencing factors in the Chinese population.
