CT-guided percutaneous approach for the treatment of peripheral pulmonary artery pseudoaneurysm: A case report.

Pulmonary artery pseudoaneurysm is a rare but life threatening complication of pulmonary tuberculosis, considered as a diagnosis and therapeutic emergency. Transarterial embolization approach has become more widespread over the last few decades, and is now considered the first-line treatment over surgery. Percutaneous embolization under computed tomography (CT) or CT scan control has recently been reported by one centre as a first-line treatment for persistent peripheral Pulmonary artery pseudoaneurysm under certain conditions. We report the case of a 23-year-old female patient admitted in emergency for moderate haemoptysis, in a context of relapsing of tuberculosis. CT scan angiogram showed a peripheral pulmonary artery pseudoaneurysm of the lower left lobe, and persisted seven days later. After multidisciplinary meeting, a minimal invasive approach was decided. The patient was treated in first-line treatment by percutaneous transthoracic embolization, under CT-guidance, using N butyl-cyanoacrylate and Lipiodol mixture, without any complication. The percutaneous minimal invasive treatment seems to be a reliable approach to treat persistent peripheral pulmonary artery pseudoaneurysm.
