The International Society of Thrombosis and Hemostasis Scientific and Standardization Subcommittee criteria were used to evaluate the effectiveness of PCCs.Results: A total of 22 patients were included in the study. Ten of the events were caused by gastrointestinal bleeding (46%). In the majority of patients, anticoagulation was prescribed for stroke prevention, atrial fibrillation, and venous thromboembolism. The median international normalized ratio was significantly lower before and after PCC administration (p<0.001). In patients treated with 4-factor PCC, the rate of thromboembolic events was 0%. The hemostatic effectiveness of PCC was effective in 19 patients. During treatment, no clinically significant bleeding complications occurred.Conclusion: Prothrombin complex concentrate can effectively reverse the effects of warfarin and rivaroxaban in patients with major bleeding, but only partially reverses the effect of dabigatran.
