Core Tip

Core tip: Management of gastrointestinal (GI) bleeding in patients with hereditary hemorrhagic telangiectasia (HHT) can be challenging when the vascular lesions recur despite repeated endoscopic treatments. There is increasing evidence supporting the use of anti-angiogenesis agents in the management of bleeding in HHT patients. Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, has been shown to reduce recurrent epistaxis. This case demonstrates the therapeutic potential of bevacizumab in patients with severe GI bleeding requiring massive transfusions.
