Unusual association of diseases/symptoms
An unusual cause of lower gastrointestinal haemorrhage
Summary
A previously unreported cause of lower gastrointestinal haemorrhage in a 63-year-old female patient on clopidogrel for cardiac comorbidities is presented. Endoscopy suggested a small bowel or colonic aetiology but failed to accurately localise the source. The patient became haemodynamically unstable despite conservative management and temporary cessation of clopidogrel. CT angiography demonstrated a pseudoaneurysm arising from the superior rectal artery. Percutaneous embolisation using coils was performed to successfully occlude the pseudoaneurysm, prevent further haemorrhage and avoid emergency colonic resection.
