Purpose
To retrospectively evaluate the characteristics of endovascular embolization for infectious pulmonary artery pseudoaneurysms (PAPs) using n-butyl cyanoacrylate dilated with iodized oil (NBCA/Lip) via systemic arterial approach.
Materials & Methods
Five patients in six cases presented hemoptysis caused by infectious PAPs were reviewed. They underwent endovascular embolization from June 2014 to January 2016. A microcatheter was inserted bronchial or non-bronchial systemic arteries associated with infectious PAPs and advanced distally. Embolization using NBCA/Lip (mixture ratio in the range of 1:4 to 1:7) was performed. Following the embolization of infectious PAPs, systemic-pulmonary artery shunts were embolized using gelatin sponge particle and/or NBCA/Lip. The efficacy and complications related to the procedures were reviewed.
Results
Two PAPs in two cases and one PAP in four cases were visualized on selective systemic arteriography. Disappearance of all PAPs was confirmed on systemic arteriography and immediate hemostasis was obtained in all cases. The accumulation of NBCA/Lip into the pseudoaneurysms through systemic-pulmonary artery shunts was detected in two cases. As a minor complication, mild chest pain was presented in three cases. No major complications were experienced.
Conclusions
Endovascular embolization using NBCA/Lip via systemic arterial approach may be safe and effective for infectious PAPs.
