Non-surgical bleeding in cardiac surgery.

Bleeding is an occurrence stemming from complex interactions encountered in cardiac surgery and is often attributed to the perioperative administration of anti-thrombotic products if inadequate surgical haemostasis is excluded. Very occasionally, bleeding does not fit the norm and the aetiology is not a lack of surgical prolene or an iatrogenic-induced coagulopathy. Patients who present for cardiac surgery should be questioned carefully for a history of bleeding; however, patients at risk are not always identified. This case presents a series of haemorrhagic events incorrectly labelled as surgical complications resulting from an uncommon but not insignificant undiagnosed condition. The existing literature outlining protocols to safely manage patients with haemophilia during the perioperative cardiac surgical period is discussed in this report. This case explicitly demonstrates the importance of preoperative identification to avoid the morbidity that can result from cardiac surgery in an undiagnosed haemophilic patient.
