We described a case of a new, atypical pulmonary arteriovenous malformation (AVM) during advanced pregnancy, in a previously well screened woman with known hereditary hemorrhagic telangiectasia (HHT) and a remote history of pulmonary AVM embolization. A 29-year old woman, gravida 3, para 2, at 35 weeks' gestation was admitted following a first episode of massive hemoptysis. Pulmonary angiograph...

Time-resolved, contrast-enhanced 3D MR angiography combined with parallel imaging at 3T was applied to an intracranial arteriovenous malformation, a dural arteriovenous fistula, and an extracranial facial arteriovenous malformation. The temporal resolution was one image every 1.5 seconds. Arterial feeders were depicted in all three cases. Early venous drainage was observed in the intracerebral ...

Pulmonary varix is a rare entity that presents as a focal aneurysmal dilatation of the pulmonary vein and is frequently mistaken for a pulmonary arteriovenous malformation (PAVM). It is important to distinguish between pulmonary varix and PAVM because the former does not usually require treatment. We present the findings of non-contrast-enhanced magnetic resonance angiography with the time-spat...

We read with interest the report by MONTANI et al. [1] of fatal rupture of pulmonary arteriovenous malformation (AVM) in a patient with hereditary haemorrhagic telangiectasis (HHT) and severe pulmonary arterial hypertension (PAH) confirmed by right heart catheterisation. The authors hypothesised that bleeding from pulmonary AVM may have been facilitated by increased mean pulmonary artery pressu...

Neurogenic pulmonary oedema followed a subarachnoid haemorrhage secondary to an arteriovenous malformation in an eight-year-old boy. Despite a complicated course, he made a full recovery. Neurogenic pulmonary oedema is rare in childhood. It is sudden in onset, and potentially fatal, but is amenable to prompt and vigorous treatment.

Pulmonary arteriovenous malformation (PAVM) is a rare condition in which there is abnormal connection between pulmonary arteries and veins. The disorder usually appears in late childhood or early adult life, with dyspnea on exertion, clubbing or cyanosis. We present two patients with severe cyanosis and their work-up to diagnosis of PAVM, as a rare cause of cyanosis in childhood.

pulmonary arteriovenous malformations (avms) are rare vascular malformations of the lung that usually led to a notable risk of serious and life-threatening complications. there is considerable debate about the best management of strategies for the group of patients with diffuse avms. several therapeutic options have been reported for management of this abnormality among which coil embolization ...
