Pulmonary arteriovenous malformation (PAVM) is a rare disease disproportionally affecting patients with hereditary hemorrhagic telangiectasia and may be associated with other pulmonary or infectious etiologies. Respiratory symptoms are the most common, including dyspnea, hypoxemia, and hemoptysis. Due to the impairment of normal pulmonary filtration function, patients with PAVM are at risk for embolic events, ranging from ischemic strokes to brain abscesses. More importantly, PAVM can enlarge over time or with physiological changes, which may lead to catastrophic hemorrhages and increased embolization risks. From imaging perspective, echocardiography with contrast bubbles and computed tomography can both be used to diagnose PAVMs with high sensitivity and specificity. Treatment modalities have evolved from invasive surgeries to transluminal catheter-based interventions. In recent decades, the evolution of interventional techniques and equipment has resulted in a high technical success rate for the treatment of PAVMs. Here, we present the interventional PAVM treatment protocol at our institution.
