The management of parturients with coagulopathy involves a careful assessment of risks and benefits to determine the most appropriate plan for workup and management. Pregnant patients with factor XI deficiency present a particularly complex scenario because frequently their diagnosis is revealed through laboratory testing and the clinical implications are unclear. In this infographic, we will review the normal function of factor XI, how to evaluate factor levels in the context of clinical history, and management strategies in the setting of pregnancy.
