The performance of surgery and invasive procedures in patients with haemophilia is currently facing new challenges globally. The first is the appropriate application of low-dose protocols of clotting factor concentrates (CFC) achieving adequate perio- perative haemostasis in resource constraint environments. The increasing availabil- ity of CFC through humanitarian aid programmes allows more invasive surgeries to be performed for which efficacy and safety data should be more widely collected and reported. Second, extended half-life CFC that are increasingly available in many countries represent valuable alternatives to standard half-life products in surgical pa- tients allowing reduced number of infusions and lower consumption, in particular for extended half-life factor IX. Third, in the era of recently introduced non-factor proph- ylaxis, some minor surgical procedures can now be performed without additional haemostatic treatment, others with few low-dose administrations of CFC or bypass- ing agents. Additional factor VIII or bypassing treatment has proven to be safe and effective in association with emicizumab for major surgeries, and it was effectively given at low doses in association with fitusiran. No thrombotic complications have been reported in the surgical setting so far. A multidisciplinary team/facility remains crucial to manage major surgery in patients on prophylaxis with these new agents.
