[Does transradial cardiac catheterization affect coronary artery bypass grafting?].
Recent technological advances have enabled the miniaturization of catheters for coronary angiography and intervention. As a result of this advancement, the transradial approach is becoming more popular. The advantages of this approach include a lower incidence of access site complications, earlier patient ambulation, improved patient satisfaction, and lower cost. The cardiologists of our institute have introduced this technique without delay and have taken the initiative in Japan. However, there are concerns regarding the effect of transradial cardiac catheterization on the condition of radial artery grafts for coronary artery bypass grafting (CABG). In this study, we evaluated the influence of transradial catheterization on CABG. We retrospectively evaluated 157 patients who had undergone CABG using the radial artery. The condition of the grafts was assessed intraoperatively. Postoperative coronary angiography was carried out 3 months after the surgical intervention. The patency of the grafts was assessed by 2 cardiologists. One-quarter of the radial artery grafts were affected by transradial catheterization. Since most of them were located only at the puncture site, the graft itself was capable of being used for grafting after the resection of its affected distal end. The patency rate was not affected by transradial catheterization.
