• platelets ≥ 50.0 x109/L;
• fibrinogen ≥0.5 x lower limit of normal;
• international normalized ratio 2.8 mmol/l.

Exclusion criteria

• Any clinical evidence of mechanical or non-thrombotic occlusion
• High risk for bleeding events
• High risk for embolic complications
• Any condition for which bleeding constitutes a significant hazard or would be particularly difficult to manage

• obstetrical delivery
• percutaneous biopsy of viscera or deep tissues
• puncture of non-compressible vessels
