Angioembolisation of pulmonary artery pseudoaneurysm arising in H1N1 influenza viral pneumonia

Joseph C Lee et al. Heart Lung Circ. 2011 Sep.

Abstract

A 51 year-old Aboriginal woman was diagnosed with H1N1 influenza virus and methicillin-resistant Staphylococcus aureus. Contrasted CT of the pulmonary and bronchial vasculature undertaken for investigation for of haemoptysis revealed an 11 mm left upper lobe pulmonary artery pseudoaneurysm (PAP). The PAP was successfully treated with angioembolisation of the parent artery with two platinum coils. Pulmonary artery pseudoaneurysms are uncommon but potentially life-threatening and have not previously been reported in association with H1N1 influenza viral pneumonia, which has been prominent in recent times in both medical literature and popular press.
