Occlusion of pulmonary arteriovenous malformations by use of vascular plug

Acta Radiologica, 2007
Pulmonary arteriovenous malformations are commonly treated by embolization with coils or balloons to prevent cerebral complications and to raise the oxygenation of the blood.

CT Appearance of Pulmonary Arteriovenous Malformations and Mimics.

Radiographics, 2022
A pulmonary arteriovenous malformation (PAVM) is a fistulous connection between a pulmonary artery and a pulmonary vein that bypasses the normal pulmonary capillary bed resulting in a right-to-left shunt.

Pulmonary Arteriovenous Malformations

Chest, 2013
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. As a consequence, patients with PAVM can have hypoxemia and paradoxical embolization complications, including ...

Pulmonary arteriovenous malformations

Clinical Radiology, 1998
Pulmonary arteriovenous malformations (PAVMs) are uncommon lesions, but are the cause of considerable morbidity and occasional mortality. They most commonly occur in association with hereditary haemorrhagic telangectasia and screening of families with this condition is therefore important.

Pulmonary arteriovenous malformations

The Indian Journal of Pediatrics, 2001
Pulmonary arteriovenous malformations rarely present in childhood. Two cases are presented in this report. Both the cases presented clinically with cyanosis and clubbing without a cardiac murmur. The second case had cerebral abscess in addition. Both the cases underwent a contrast-enhanced echocardiography which suggested the presence of pulmonary ...

Pulmonary Arteriovenous Malformations

Chest, 2000
Helical CT scan (HCT), a noninvasive method, can detect pulmonary arteriovenous malformations (PAVMs). Its sensitivity is superior to that of global digitalized angiography, but patients receive a significant dose of radiation during diagnostic HCT. We compared HCT to contrast-enhanced pulmonary magnetic resonance angiography (CEMRA), a new noninvasive

Pulmonary Arteriovenous Malformation

Circulation, 1999
A35-year-old white woman with a history of migraine headaches and a grade 2 systolic murmur presented with symptoms of slurred speech, left-sided facial droop, and left hemiparesis after a hysterectomy. These symptoms resolved over several days, and in an effort to identify a potential cardiac source of embolism, a transesophageal echocardiogram was ...

Pulmonary arteriovenous malformations and their mimics

Clinical Radiology, 2015
Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between the pulmonary arteries and veins, which result in a right-to-left (R-L) shunt with resultant hypoxemia, the severity of which will depend upon the size and number of lesions. Most PAVMs occur in individuals with hereditary haemorrhagic telangiectasia (HHT) and are a cause

CT Angiography Findings of Pulmonary Arteriovenous Malformations in Children and Young Adults With Hereditary Hemorrhagic Telangiectasia.

AJR. American journal of roentgenology, 2020
OBJECTIVE. The purpose of this study was to evaluate the CT angiography (CTA) findings of pulmonary arteriovenous malformation (PAVMs) in patients with hereditary hemorrhagic telangiectasia and to correlate these findings with those of graded contrast ...

Telangiectatic Pulmonary Arteriovenous Malformation

Journal of Thoracic Imaging, 2003
Telangiectatic pulmonary arteriovenous malformation is defined as a pulmonary arteriovenous malformation involving every segmental artery of at least one lobe of the lung. The authors report a case of telangiectatic pulmonary arteriovenous malformation in the left lower lobe of the lung.
