Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In previous attemps to answer the question of risk-benefit of postpartum thromboprophylaxis, researchers were faced with low recruitement rates. The goal of this pilot feasibility randomized controlled trial of postpartum pharmacological thromboprophylaxis is to examine the feasibility (recruitement rate) and participation rate at the Geneva University Hospitals
