Published: January 2022

Background: Pulmonary arteriovenous malformations are mostly caused by congenitally abnormal shunts between pulmonary arteries and pulmonary veins.

Case Presentation: A 74-year-old Japanese woman with a history of bronchiectasis was admitted to our hospital because of dyspnea on exertion. Pulmonary angiography and reconstructed three-dimensional contrast-enhanced computed tomography images showed shunts between pulmonary arteries and pulmonary veins, indicating a diagnosis of pulmonary arteriovenous malformations. Coil embolization of the shunts was successful.

Conclusions: Our findings imply that bronchiectasis can cause pulmonary arteriovenous malformations, and thus patients who present with hypoxemia with bronchiectasis should be carefully evaluated.

Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.

Osler-Weber-Rendu syndrome, or hereditary hemorrhagic telangiectasia (HHT), is a rare vascular disorder characterized by arteriovenous malformations (AVMs) in various organs, including the lungs. Pulmonary AVMs (PAVMs) are especially worrisome due to their potential to form right-to-left shunts, resulting in life-threatening complications such as paradoxical embolism and stroke . We present a case of fatal air embolism in a young patient with a known history of HHT and recurring hemoptysis.

Pulmonary arteriovenous malformation (PAVM) is a congenital vascular pathology, which is caused by the presence of a direct connection between the branches of the artery and the veins of the lungs, and the discharge of unoxygenated blood into the arterial bed. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and, in some cases, may be accompanied with severe circulatory disorders.

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.

Hereditary haemorrhagic telangiectasia (HHT) is a vascular dysplasia inherited as an autosomal dominant trait and caused by loss-of-function pathogenic variants in genes encoding proteins of the BMP signalling pathway. Up to 90% of disease-causal variants are observed in ENG and ACVRL1, with SMAD4 and GDF2 less frequently responsible for HHT. In adults, the most frequent HHT manifestations relate to iron deficiency and anaemia owing to recurrent epistaxis (nosebleeds) or bleeding from gastrointestinal telangiectases.
