Nov 20, 2024 · Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between pulmonary arteries and veins [1]. Alternative names include pulmonary arteriovenous fistulae, pulmonary arteriovenous aneurysms, cavernous angiomas of the lung, and pulmonary telangiectases [2].

Oct 28, 2024 · Pulmonary arteriovenous malformations (AVMs) are rare vascular anomalies of the lung, in which abnormally dilated vessels provide a pulmonary artery-to-pulmonary vein right-to-left shunt. They are generally considered direct high flow, low-resistance fistulous connections between the pulmonary arteries and veins.

Nov 10, 2020 · A pulmonary arteriovenous malformation (PAVM) is a rare pulmonary condition characterized by a pathological right-to-left shunt that disrupts normal gas exchange and venous blood filtration in the pulmonary circulation.

Jun 1, 2018 · Pulmonary arteriovenous malformations (PAVMs) are rare, low-resistance, high-flow abnormal vascular structures that connect a pulmonary artery to a pulmonary vein bypassing the normal pulmonary capillary bed and resulting in an …

Pulmonary arteriovenous malformations (PAVMs) are abnormal direct vascular communications between pulmonary arteries and veins which create high-flow right-to-left shunts. They are most frequently congenital, usually in the setting of hereditary hemorrhagic telangiectasia (HHT).

What is a pulmonary arteriovenous malformation (AVM)? Arteriovenous malformations (AVMs) refer to arteries and veins with abnormal connections between them. In the lungs, arteries first carry blood from the heart to smaller arteries which …

Pulmonary arteriovenous malformations (PAVMs) are direct high flow, low-resistance fistulous connections between pulmonary arteries and veins (Fig. 1). The resulting right to left shunt can be clinically silent in small malformations, but often results in hypoxia or a variety of neurologic sequelae in larger malformations.

Pulmonary arteriovenous malformations (AVMs) represent direct connections between the pulmonary artery and vein.

Apr 9, 2012 · Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular structures that most often connect a pulmonary artery to a pulmonary vein, bypassing the normal pulmonary capillary bed and resulting in an intrapulmonary right-to-left shunt.

Pulmonary arteriovenous malformations (PAVMs) have a variety of causes, but the most common cause is HHT (hereditary hemorrhagic telangiectasia). HHT is a genetic condition that causes AVMs to form in various locations throughout the body.
