Endovascular management of massive hemoptysis due to covid-19 related pulmonary artery pseudoaneurysm: A rare entity

Pulmonary Artery Pseudoaneurysm in COVID-19-Associated Pulmonary Mucormycosis: Case Series and Systematic Review of the Literature

“…Hemoptysis is unusual in coronavirus disease (COVID-19), [ 8 ] and has been observed with pulmonary embolism or invasive pulmonary aspergillosis. [ 9 – 11 ] Bronchial circulation (contributes to 2% of the blood supply to the lungs) accounts for most cases of hemoptysis. Pulmonary artery as a source of bleeding is uncommon, easily missed, and challenging to manage.…”

Pulmonary pseudoaneurysm presented as a lung nodule after recovering from Covid‐19 pneumonia

“…The pathogenesis of PAPs was proposed in three basic components: proinflammatory with endothelial damage, immune-thrombogenic and cavity with adjacent direct injury. 6 In conclusion, PAPs are rare but potentially fatal cause of haemoptysis. Early detection and treatment are crucial to improve outcomes.…”

“…Several studies have reported PAPs presented by massive haemoptysis in severe Covid‐19 pneumonia. Two cases reported PAPs associated with extensive lung lesion with cavity or pneumatocele, 5 , 6 while another case reported 8‐month delayed PAPs. 7 Embolization was performed successfully in all cases.…”

“…Early detection and treatment are crucial to improving outcomes. [5][6][7] We presented the interesting sequelae of severe Covid-19 pneumonia. The patient presented an abnormal lung nodule after recovering from the disease.…”
