Aim To evaluate the feasibility of using radial artery as a bridging vessel for coronary artery bypass grafting (CABG) after transradial artery intervention. Methods The clinical data of 168 patients with the use of radial artery as a bridging vessel for CABG were reviewed retrospectively. According to whether or not using radial artery as bridging vessel after transradial artery intervention, 168 patients were divided into intervention group (76 cases) and non-intervention group (92 cases). The follow-up results were compared between the two groups. Results There was no statistical difference in the clinical data between the two groups (P＞0.05). Compared with the intervention group, the vascular patency rate of radial artery bridge was significantly increased and the incidence of myocardial ischemia was significantly reduced in the non-intervention group; The differences were statistically significant between the two groups (P＜0.05). There was no significant difference in the incidence of related complications of radial artery acquired in the two groups, such as operative side forearm incision infection, thumb numbness, osteofascial compartment syndrome, and so on (P＞0.05). Conclusion It is possible to improve the patency of bridging vessel and improve the clinical effect of CABG by selecting the radial artery as a bridging vessel without transradial artery intervention.
