In this work we have tried to elucidate whether telangiectases are dilatations of the arteriolar or the venular sections of the circulation system. To this end, we have made use of resources which have allowed us to study in the first place, the wall of these small vascular dilatations and, in the second place, their content. Through our studies we could determine that telangiectases are originated by dilatation of the venular sector of the circulatory system.

Introduction: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disease and screening to detect pulmonary arteriovenous malformations (PAVMs) is important to prevent complications. In adults, transthoracic contrast echocardiogram (TTCE) is used to screen PAVMs. In children, a conservative screening method seems to be sufficient to rule out major PAVMs and prevent them from PAVM-related complications.

To analyze the survival status and prognostic factors of patients with hereditary hemorrhagic telangiectasia-associated pulmonary arterial hypertension (HHT-PAH). This prospective study included patients diagnosed with HHT-PAH at the Fuwai Hospital of the Chinese Academy of Medical Sciences and Guangdong General Hospital from August 2009 to December 2019. Patients were followed up every 6 months±2 weeks, with all-cause mortality as the study endpoint.
