Purpose
To evaluate the therapeutic approaches for pulmonary artery pseudoaneurysms (PAPs) with various etiologies and types, and its outcomes.
Materials and Methods
Between March 2010 and January 2023, a total of 26 PAPs were treated in 25 patients. The patient characteristics, etiologies, therapeutic approaches, and outcomes were evaluated.
Results
The etiologies of PAPs were pulmonary tuberculosis (n=22), necrotizing pneumonia (n=3), and iatrogenic (n= 1). Pulmonary arteriography was performed in 18 patients whose PAP was contiguous to pulmonary artery or iatrogenic. Among these, 12 and 1 underwent pulmonary artery embolization (PAE) and medical treatment, respectively. Remaining 5 patients, whose PAP was not detected in pulmonary arteriography, underwent bronchial or nonbronchial systemic arteriography. The patients with isolated or small PAP (≤5mm) underwent bronchial or nonbronchial systemic arteriography (n=7) except one patient showed no further hemoptysis after medical treatment. In 12 patients who underwent bronchial or nonbronchial systemic arteriography, PAE via systemic to pulmonary shunt or bronchial (n=6) or nonbronchial systemic artery embolization (BAE or SAE) for corresponding area (n=6) were performed. Regression of PAPs or cessation of the hemoptysis were observed in 22 PAPs. Two patients underwent BAE or SAE for corresponding area received operation in follow up period. Two patients underwent PAE were expired due to sepsis or massive blood loss.
Conclusion
PAE is effective for treating PAP and systemic to pulmonary shunt can be alternative route for PAE. In addition, BAE or SAE and medical treatment can be considered for small isolated PAP or nonvisualized PAP on pulmonary arteriography.
