Controversies in Venous Thromboembolism Risk Assessment in Inflammatory Bowel Disease: A Narrative Review.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition affecting the gastrointestinal tract with increasing rates of incidence and prevalence across the world. Complex inflammatory and prothrombotic pathophysiology in IBD makes venous thromboembolism (VTE) a common complication with significant morbidity and mortality. This risk is increased in pregnancy. As we continue to understand the pathogenesis of IBD, this article highlights the continued risk of VTE following discharge, for which there is currently no clear guidance, yet the risk of VTE remains high. Furthermore, we discuss this increased VTE risk in the context of pregnant IBD patients and the relevant current guidelines. Alongside this, medications that are used to manage IBD carry their own thrombotic risk, which clinicians should be aware of. Assessing VTE risks in IBD populations using newer medications should be a focus of future research.
