  • Title: [Peripheral Pulmonary Artery Aneurysm with Internal Thoracic Artery-Pulmonary Artery Shunt].
    Author: Hosaka Y, Yorimori S, Maeda C, Shimizu K.
    Journal: Kyobu Geka; 2023 Jun; 76(6):428-431. PubMed ID: 37258019.
    Abstract:
    An 82-year-old woman with past history of pulmonary nontuberculous mycobacterial infection complained of hemoptysis and was pointed out the strongly stained nodule in the middle lobe of the right lung on chest enhanced computed tomography (CT), which was suggested to be peripheral pulmonary artery aneurysm. Angiography of the right internal thoracic artery (RITA) revealed the peripheral pulmonary artery aneurysm with the shunt from the branch of the RITA, which was considered to be the cause of hemoptysis. Transcatheter arterial embolization was performed for the branch of the RITA 2 times, however, the hemoptysis recurred again after 5 months. Therefore, after the third embolization for the RITA, the right middle lobectomy with amputation of the shunt vessel was performed. The patient has been well without hemoptysis for one year and 6 months after the surgery.
