YES
The purpose of this study is to investigate the presence of visceral AVMs in HHT patients, their symptoms and treatments, and the correlation with the results of genetic testing in Japan.
Others
In this study, the frequency of AVM/AVF in each organ associated with HHT and the relationship with the results of genetic testing will be collected jointly at HHT treatment centers in Japan, which will provide meaningful findings that can be fed back to clinical practice, enabling physicians to offer appropriate testing and treatment and provide very useful information for systemic disease management in HHT patients in Japan.
The prevalence of visceral AVMs, symptomatic prevalence, and the proportion of patients treated for them will be analyzed to assess the frequency of HHT-associated visceral AVMs in Japan. In addition, for those for which genetic test results are available, we will analyze the prevalence of HHT1 (ENG gene mutation) and HHT2 (ACVRL1 gene mutation) in terms of the prevalence of visceral AVMs, symptomatic prevalence, and the proportion of patients treated for them. The differences in visceral AVMs by HHT subtype will also be evaluated.
