Druk-gestuurde pneumatische compressie vermindert radiale arterieocclusie na transradiale coronaire ingrepen

OBJECTIVES: To evaluate a pressure-measured pneumatic radial compression protocol and its association with radial artery occlusion (RAO) after transradial coronary procedures. DESIGN: This single-center retrospective historical cohort included 514 consecutive patients treated between February and December 2025. The control group received conventional screw-type compression with clinically guided staged adjustment (n = 260), whereas the observation group received pneumatic compression with quantitative pressure measurement and individualized staged adjustment (n = 254). The primary outcome was RAO at 24 h; RAO at 7 days and other clinical outcomes were secondary outcomes. RESULTS: The observation group had lower observed RAO rates than the control group at 24 h [2.8% (7/254) vs. 7.7% (20/260), p = 0.012] and 7 days [2.0% (5/254) vs. 5.4% (14/260), p = 0.040]. After Firth penalized logistic regression, the protocol remained associated with lower odds of RAO at 24 h (adjusted OR = 0.358, 95% CI: 0.143-0.809; p = 0.013). The observation group also had lower pain scores at 6 and 24 h (both p < 0.001), higher digital SpO2 values at 2, 4, and 24 h (all p < 0.001), higher primary hemostatic success [97.2% vs. 93.5%, p = 0.042], and fewer patients with puncture-site oozing [2.8% vs. 6.9%, p = 0.028] or at least one local complication [11.4% vs. 28.1%, p < 0.001]. CONCLUSIONS: Pressure-guided pneumatic compression was associated with lower observed RAO rates and more favorable hemostatic and local outcomes than conventional screw-type compression. STUDY REGISTRATION: This study was a retrospective cohort study and did not involve a prospective intervention; therefore, clinical trial registration was not required.
