Pulmonary artery pseudoaneurysm arising secondary to cavitary pneumonia

Giant pulmonary pseudoaneurysm following balloon dilatation of the pulmonary artery to relieve pulmonary band

Pulmonary artery pseudoaneurysms are uncommon. They may occur secondary to trauma, infectious diseases, vasculitis syndromes, neoplasms, congenital diseases, and pulmonary hypertension. Due to increasing number of cardiac interventions, iatrogenic complications are among the major causes of pulmonary artery pseudoaneurysms.In this report, we present a 6-month-old patient with pulmonary pseudoaneurysm that occurred following pulmonary balloon angioplasty for the relief of a pulmonary band.

SK, Talwade R, Lokeshwaran S, K. PV. Endovascular Treatment of Pulmonary Artery Pseudoaneurysms Post-COVID-19 Pneumonitis

Pulmonary artery pseudoaneurysms (PAPs) are uncommon entities consisting of contained rupture of the pulmonary artery and are a potentially fatal cause of hemoptysis. We describe two index cases of left lower lobe PAPs and arterial ectasia post-COVID-19 pneumonitis and their endovascular treatment with Amplatzer vascular plug, coils, and glue.

Pulmonary Artery Pseudoaneurysm in a Child With β-Thalassemia Major

Pulmonary artery aneurysms and pseudoaneurysms are rare vascular anomalies in children that can lead to massive hemoptysis resulting in severe morbidity and even mortality. High level of clinical suspicion, timely diagnosis, and prompt management are important for a better outcome. Here, we report a case of a 14-year-old adolescent with β-thalassemia major who presented with life-threatening hemoptysis due to pulmonary artery pseudoaneurysm and was successfully treated with coil embolization.

Pulmonary artery aneurysm rupture

Pulmonary artery aneurysm is a disorder of varying etiology and should be diagnosed early for appropriate interventions. A 45-year-old man was hospitalized for chest pain, dyspnea, cough, chills, diarrhea, and vomiting, which had started 3 weeks before admission. Physical examination indicated a reduced vesicular murmur in the right hemithorax. A chest x-ray performed indicated a pneumothorax and pulmonary abscess in the right hemithorax. Thoracostomy released abundant purulent and fetid fluid. Direct examination of the pleural fluid using saline revealed structures similar to Trichomonas. Non-contrast chest computed tomography revealed right pneumothorax along with an irregular cavitation located at the pleuropulmonary interface of the posterior margin of the right lower lobe. A pleurostomy was performed. On the second postoperative day, the patient suffered a sudden major hemorrhage through the surgical wound and died on the way to the operating room. The autopsy revealed an abscess and ruptured aneurysm of the lower lobar artery in the lower right lung. Microscopic examination revealed extensive liquefactive necrosis associated with purulent inflammation and the presence of filamentous fungi and spores. This case can be characterized as a severe disorder that requires early diagnosis to achieve a good therapeutic response and to avoid fatal outcomes.

Emergency management of massive haemoptysis

In this manuscript, we present a rare case of massive haemoptysis secondary to rupture of a pulmonary artery aneurysm, which was unusual for having occurred in the absence of tuberculosis or a vasculitis. We describe the emergency management of this that ultimately resulted in the patient's survival from both an anaesthetic and surgical perspective, as well as discuss the role of interventional radiology in this situation.
