Overview

Aims: Hereditary haemorrhagic telangiectasia (HHT) is a rare automosal dominant vascular disease characterized by recurrent epistaxis, mucocutaneous telangiectasias and arteriovenous maloformations, which may be found in different organ systems. The aim of this paper is to present therapeutic modalities of epistaxis and to present system of observation at our department according to international guidelines.

Methods: We observe and manage patients with HHT according to international guidelines since 2015. Patients fill in the Epistaxis severity score (ESS) questionnaire at each visit. We choose therapeutic modality based on ESS score.  

Results: 6 patients are regularly observed at our department sice 2015. We found pulmonary AVMs in 2 patients and indicated gastroscopy in 3 patients. Each of therapeutic modalities for epistaxis led to at least mild severity of epistaxis in 4 patiens and moderate severity in 2 patients. Average ESS score at baseline was 6.13, after different therapeutic modalities the average score was 3.28. 

Conclusion: Despite HHT is systemic disease, there isn´t centralized care of these patients in Czech Republic. ENT doctor is often a doctor of first contact and therefore should start at least basal diagnosis and management in patients with HHT and should be aware of that management of epistaxis is different from standard epistaxis. According to our observation each patient reacts individually to different therapeutic modalities.
