Pulmonary Aneurysmal Arteriovenous Malformation Treated With a Vascular Plug.

Purpose: To report a case of an asymptomatic patient with a pulmonary aneurysmal arterio-venous malformation successfully treated with a vascular plug.

Case report: An active 30-year-old male patient, residing at 3000 ft above sea level was referred due to an incidental finding on a CT scan of a 37 mm vascular mass localized in the lower lobe of the right lung, which corresponded to a pulmonary arteriovenous malformation with a single feeding artery. The patient was treated with an Amplatzer vascular plug, which effectively excluded the afferent vessel. An angio CT at 19 months follow-up revealed a hypodense residual mass of 9.0 mm in diameter with no arterial filling or venous drainage. The patient is fully active and remains asymptomatic at 24 months follow-up.

Conclusion: An unusual case of a pulmonary aneurysmal arteriovenous malformation successfully treated with a vascular plug is presented, highlighting the efficiency of this procedure.
