Objective To investigate the effects of radial artery intervention via the distal radial artery on radial artery hemodynam-ics and stent diameter in diabetic patients.Method 92 cases of diabetic patients who underwent coronary intervention in the Depart-ment of Cardiology at Wuming Hospital affiliated with Guangxi Medical University from January 2022 to October 2023 were selected as the subjects of the study.According to the preoperative ultrasound results of the radial artery and distal radial artery,the patients were divided into experimental and control groups using digital allocation method.The experimental group adopted the method of puncture through the distal radial artery,and the control group adopted the conventional method of radial artery puncture.The changes in arterial inner diameter,blood flow velocity,and stent diameter of the punctured artery before and after surgery within 48 hours were observed in both groups.In addition,the postoperative complications were also observed.Results There was a significant difference in the change of radial artery inner diameter within 48 hours after surgery in the experimental group(2.86±0.25 mm vs.2.82±0.26 mm,P<0.01).However,there was no significant difference in blood flow velocity within 48 hours after surgery between the experimental group and the control group(42.43±1.57 vs.42.13±1.77,P>0.05).There was also no significant difference in the diameter of stents used in the two groups during the operation(3.25±0.48mm vs.3.17±0.44 mm,P>0.05).No obvious complications were found in the ex-perimental group.Conclusion The distal radial artery pathway has no significant effect on hemodynamic parameters and stent diameter in coronary intervention for diabetic patients.
