Introduction :
Distal radial (DR) approach has been reported worldwide as a safe and feasible alternative to traditional Forearm radial approach (FR) in performing coronary interventions. For local Chinese population in particular with smaller body builds, the safety, feasibility and benefit of DR approach was studied.
Objectives :
This study was designed to evaluate and improve the service quality of coronary intervention in Tseung Kwan O Hospital. We aimed to establish DR approach as a safe and comparable alternative to traditional FR approach.
Methodology :
This is an ongoing study piloted since October 2022. All patients attending Tseung Kwan O Hospital for both elective and urgent coronary procedures were recruited and randomly allocated into DR and FR groups. We evaluated the results on the number of puncture attempts, procedure duration, haemostasis and most importantly patient comfort during and after the procedure. Specific complications such as artery stenosis and occlusion were looked for during 30-days post procedure follow-up.
Result & Outcome :
Forty-eight and thirty-eight patients were recruited for analysis in DR and FR group respectively as of December 2022. There was no significant difference in puncture success rate and puncture time. Seventy-two percent of the DR cases had successful arterial puncture in single attempt, with average puncture time of 201.7 seconds. Statistically significant reduction in haemostasis time (172.7 minutes vs 194.5 minutes, p = 0.003) and no puncture site related complication including radial artery stenosis and occlusion were observed in the DR group. No significant difference was observed in patient satisfaction during and post procedure, with sixty-three percent of DR group patients reported high grade of satisfaction (VAS
