[AB0 blood groups and the risk of venous thromboembolism in connection with surgery].

It is increasingly recognised that individuals with non-0 blood groups may be at elevated risk of venous thromboembolism (VTE) compared with blood group 0 individuals. Multiple studies suggest that individuals with a non-0 blood group have an approximately twofold increased risk of VTE. The largest risk is seen in individuals with combined factor VLeiden mutation and non-0 blood group. In this review, we outline an overview of the existing literature regarding AB0 blood groups and the risk of VTE.
