Abstract
Novel influenza A H1N1 virus (pH1N1) was the predominant strain in the 2009 pandemic. It continues to circulate along with other influenza strains in the post pandemic era. This new virus is nevertheless well known for its strong association with high cardiovascular mortality and a high propensity to preferentially affect young and otherwise healthy adults, resulting in a clustering of severe and even fatal cases in patients of the productive age group. H1N1 infection is a multifaceted disease. It affects the lung parenchyma as well as the pulmonary vasculature. It also affects the multisystemic vasculature and can cause other embolic events not strictly falling in the “usual” thrombotic category. We herein present a case of H1N1 influenza pneumonia induced severe ARDS with pulmonary thromboembolism (PTE) and pulmonary fibrosis.
Highlights
The novel influenza A virus illness, which is associated with high morbidity and mortality, is known to occur as pandemic as well as epidemic worldwide
The infection causes severe non cardiogenic hypoxemic respiratory failure known as the acute respiratory distress syndrome (ARDS)[1,2]
The prominence of pulmonary thromboembolism and infarction in this case may be related to hypercoagulability, which has been reported elsewhere in patients with pandemic influenza pneumonia
