摘要
Objectives The aim of this study was to compare two hemostatic techniques, pressure technique and hemostasis, on radial artery occlusion (RAO) after transradial catheterization. Background RAO is an infrequent complication of transradial procedures. One of the strategies used to reduce this complication is the hemostasis technique. Use of pressure in hemostatic wristband, without monitoring patency, might have the same efficacy for preventing RAO. Methods This is a multicenter study encompassing patients submitted to transradial catheterization. After pneumatic wristband application, the band was deflated to the lowest allowable volume while preserving Radial artery patency was subsequently evaluated. The group with no return of plethysmographic curve was labeled minimum pressure, and the group in which the signal returned was labeled patent hemostasis. RAO was verified by Doppler evaluation within the first 24 hours of the procedure. Results A total of 1082 patients were enrolled, with mean age of 61.4 ± 10.4 years. The majority (61.0%) were male and 34.5% had diabetes. Patent hemostasis was achieved in only 213 cases (20%). Early RAO occurred in 16 patients (1.8%) in the pressure group and in 4 patients (1.9%) in the hemostasis group (P=.97). No major bleeding was observed among the entire cohort. EASY scale for hematoma grade was similar between the cohorts (EASY grades 1-3: 7.0% in the pressure group vs 7.5% in the hemostasis group; P=.96). Conclusion Checking radial patency during hemostatic compression may not be necessary after the procedure when adopting a mild and short hemostatic compression.
