Efficacy of the hemostatic device VasoSTAT and the study of hemostatic factor

Recently, trans-radial intervention has gained popularity as a common procedure to reduce hemorrhagic complications. However, the cuff-type hemostatic device (TR Band) previously used at our institution required 6 h to achieve hemostasis. Since July 2016, we have been using the VasoSTAT, a new hemostatic device that could achieve hemostasis in 4 h. In a verification study, we found that prolonged activated clotting time (ACT) was related to transient hemorrhage occurrence after the hemostatic procedure. Therefore, we designed a hemostatic protocol based on ACT and evaluated its efficacy. In this retrospective and observational study, 78 and 111 patients used the VasoSTAT and TR Band, respectively, from July 2015 to May 2017. In the VasoSTAT group, the ACTs were significantly lower in the hemostasis success (246 ± 46 s) than in the failure group patients (327 ± 59 s) ( P
