Abstract
Paediatric central venous sinus thrombosis (CVST) is an uncommon but important life-threatening complication of inflammatory bowel disease (IBD). As the incidence of IBD has increased in the last four decades, paediatricians need to be aware of this complication. There is currently no consensus on when children with IBD should receive prophylactic anticoagulation. We present the case of a young girl with ulcerative colitis who suffered an acute ischaemic event secondary to a CVST during an acute flare of her disease. We aim to bring awareness to CVST in IBD due to its high risk of morbidity and mortality.
