Pulmonary Artery Pseudoaneurysm as a Delayed Vascular Complication of COVID-19: Successful Endovascular Occlusion Using an Amplatzer Muscular VSD Occluder.

Pulmonary artery pseudoaneurysm (PAP) is a rare but potentially life-threatening condition that can arise secondary to infections, including COVID-19. Early recognition and timely intervention are crucial to prevent complications. We describe a 41-year-old woman with type 2 diabetes who presented with hemoptysis and persistent dry cough 2 months after recovering from COVID-19 pneumonitis. Computed tomography angiography revealed a 2.3 cm pseudoaneurysm in the right lower lobe pulmonary artery, associated with a cavitary lesion. Selective angiography confirmed a 25 mm PAP. Owing to its wide neck, coil or glue embolization was considered unsuitable. A 10-mm muscular-type Amplatzer ventricular septal occluder was successfully deployed, achieving complete exclusion of the pseudoaneurysm while maintaining distal arterial flow. The patient remained free of hemoptysis, and follow-up imaging demonstrated effective occlusion with a small residual sac. PAP should be considered in COVID-19 survivors presenting with hemoptysis. Endovascular closure using Amplatzer devices offers a safe and effective treatment, particularly for large or wide-necked pseudoaneurysms where coil or glue embolization techniques may be inadequate.
