Endovascular Glubran 2 and coiling embolization of a pulmonary artery pseudoaneurysm: A case report

Abstract

Pulmonary artery pseudoaneurysm (PAP) is a rare but potentially life-threatening condition that necessitates prompt diagnosis and intervention. PAP is commonly associated with hemoptysis, which, when massive (>300 ml/day), carries a 50 % mortality rate. We present the case of a 63-year-old male with a history of chronic obstructive pulmonary disease (COPD) associated with recent episodes of pneumonia, tobacco use and hypertension who was admitted to the emergency department with high fever, productive cough, dyspnea, chest pain and hypoxia with subsequent development of hemoptysis. An urgent chest CT angiogram (CTA) revealed a 15-by-17 mm central enhancing area arising from the right pulmonary artery in the upper-to-mid right lobe within a cavitating pneumonitis parenchymal lung consolidation, compatible with a pulmonary artery pseudoaneurysm. The patient underwent successful endovascular embolization using Glubran 2 and metallic coils. Post-procedural imaging confirmed complete occlusion of the pseudoaneurysm, with no residual flow and resolution of hemoptysis.
