Pulmonary artery stenting in a patient with Takayasu's arteritis using a novel balloon-expandable covered stent.

Patients with Takayasu's arteritis have pulmonary artery involvement more commonly than previously appreciated. The majority of these lesions are in segmental or sub-segmental arteries, but there are some patients who have severe stenosis of the main pulmonary arteries. Interventional treatment of these patients is technically feasible, but there are only limited case reports describing such intervention.
