Selective embolotherapy as a treatment option for lower gastrointestinal haemorrhage following open-heart surgery.

Lower gastrointestinal haemorrhage following cardiac surgery is a rare but potentially life threatening complication. Conservative or endoscopic management often fails to detect and control the bleeding, with surgery, often in the form of a major colonic resection, being the last resort. Surgical intervention, however, is associated with high morbidity and mortality.
