Reproducibility of right-to-left shunt quantification using transthoracic contrast echocardiography in hereditary haemorrhagic telangiectasia
AIM Transthoracic contrast echocardiography (TTCE) is recommended for screening of pulmonary arteriovenous malformations (PAVMs) in hereditary haemorrhagic telangiectasia. Shunt quantification is used to find treatable PAVMs. So far, there has been no study investigating the reproducibility of this diagnostic test. Therefore, this study aimed to describe inter-observer and inter-injection varia...
متن کاملPulmonary shunt fraction measurement compared to contrast echocardiography in hereditary haemorrhagic telangiectasia patients: time to abandon the 100% oxygen method?
BACKGROUND The presence of pulmonary right-to-left shunting (RLS) is associated with severe neurological complications from paradoxical embolisation in patients with hereditary haemorrhagic telangiectasia (HHT) and screening is warranted. Pulmonary shunt fraction measurement with the 100% oxygen method can be used for the detection and quantification of functional pulmonary RLS, although transt...
متن کاملQuantification of right-to-left shunt with (99m)Tc-labelled albumin macroaggregates and 100% oxygen in patients with hereditary haemorrhagic telangiectasia.
Pulmonary arteriovenous malformations (PAVMs) are often associated with hereditary haemorrhagic telangiectasia (HHT). The quantification of right-to-left shunts in patients with PAVMs is important in diagnosis and follow up. Traditionally, this shunt is measured by the 100% oxygen method, in which the value for the arteriovenous difference in oxygen content, Cao(2)-CVO(2) (where Cao(2) is the o...
متن کاملHereditary haemorrhagic telangiectasia.
Hereditary haemorrhagic telangiectasia (Osler-Rendu-Weber syndrome) is an autosomal dominant vascular disorder, manifesting with telangiectases and bleeding in different parts of the body. We report a patient who presented with bleeding from various sites.
متن کامل'Pseudocirrhosis' in hereditary haemorrhagic telangiectasia.
Telangiectasia-associated hepatic fibrosis (TAHF) in a 68-year-old woman with hereditary haemorrhagic telangiectasia (HHT) is described. The patient died of oat-cell carcinoma of the lung. In addition to the structural alterations which have been described previously in HHT, the liver exhibited focal midlobular hepatocytic necrosis and tumour metastases. The possibility that treatment of HHT wa...
