Statistics

Pulmonary arteriovenous malformations are rare anomalies that carry a considerable risk of serious complications such as cerebral thromboembolism or abscess and pulmonary hemorrhage. The first-line treatment of such malformations is detachable coil or balloon embolotherapy. However, coils and balloons may migrate and cause paradoxical embolism especially in malformations with large arteriovenous shunts. We report a case in which we used a new vascular occlusion device (Amplatzer vascular plug) to occlude a pulmonary arteriovenous fistula in a patient with Rendu–Osler–Weber syndrome.

Key words:
Pulmonary arteriovenous malformations
Amplatzer vascular plug
Embolotherapy
Rendu-Osler-Weber Syndrome
Hereditary hemorrhagic telangiectasia

Las malformaciones arteriovenosas pulmonares son anomalías poco frecuentes del pulmón, que entrañan un riesgo considerable de complicaciones graves como la tromboembolia cerebral, el absceso cerebral y la hemorragia pulmonar. La embolización con coils o con balones desprendibles es el tratamiento de elección. Sin embargo, éstos pueden migrar y producir embolia paradójica, especialmente en las malformaciones con comunicaciones arteriovenosas grandes.

Presentamos un caso en el que utilizamos un nuevo dispositivo de oclusión vascular (tapón vascular Amplatzer) para ocluir una fístula arteriovenosa pulmonar en un paciente con síndrome de Rendu-Osler-Weber.

Palabras clave:
Malformaciones arteriovenosas pulmonares
Tapón vascular Amplatzer

Síndrome de Rendu-Osler-Weber
