Proximal pulmonary artery aneurysms in patients with pulmonary artery hypertension: complicated cases.
Cases with proximal pulmonary artery aneurysm (PAA) sometimes have severe complications. We report 4 cases of proximal PAA complicated by pulmonary hypertension. Three cases had proximal PAA and one had both proximal and peripheral PAA. Complications associated with proximal PAA are compression of the bronchus, dissection and/or rupture of the pulmonary artery, and thrombus of the pulmonary artery. The available medical treatments have limitations. Two of our patients with proximal PAA are awaiting lung transplantation.
