SUMMARY
Hereditary haemorrhagic telangiectasia (HHT) is a rare genetic disorder that causes mucocutaneous telangiectasia and visceral arteriovenous malformations (AVMs). Recurrent iron deficiency and anaemia are significant complications often treated by haematologists. Bevacizumab, an anti-VEGF monoclonal antibody, has been implemented to target elevated levels of VEGF as seen in HHT patients. We present a single centre case series of three patients with recurrent bleeding issues due to HHT who have been treated with bevacizumab. All three patients were benefited in terms of mean haemoglobin, need for iron infusions and number of haemostatic interventions. Based on our own case series and existing literature, systemic bevacizumab appears to be effective in the treatment of bleeding-related conditions. However, the optimal dose and treatment strategy has yet to be determined. Randomised controlled studies are needed to further support the indication of bevacizumab in HHT.
