CASE REPORT
A 60-year-old woman was admitted to the hospital due to right periscapular dull pain, which worsened with changes in body position. She also complained from shortness of breath, hoarseness, and dysphagia. The patient had no known history of atherosclerosis, chronic or acute lung disease, or thoracic trauma. A chest X-ray revealed the presence of an expanded shadow at the right lung hilum with clearly defined oval structures. Multispiral computed tomography (MSCT) (Figure 1) and selective angiography of the right bronchial artery (Figure 2) were performed, revealing 3 bronchial artery aneurysms (BAA) with cavities, measuring 76mm, 25mm, and 22mm. Aneurysms were located in the posterior right mediastinum under the tracheal bifurcation.
The patient was referred for surgery. A left-side thoracotomy was performed along 4 intercostal spaces, after which the pulmonary ligament, esophagus, left main bronchus, and tracheal bifurcation were mobilized. Consequently, the descending aorta and its branches were isolated and access to the contralateral pleural cavity was obtained. In the posterior mediastinum, three aneurysms were found: one large aneurysm measuring 7cm (Figure 3), and two smaller aneurysms measuring 1.5cm and 2cm, respectively. The feeding arteries were identified and stapled, followed by excision of the aneurysms. The incision was closed and drains were positioned. The patient was transferred to the intensive care unit (ICU) with no complications.
Mechanical ventilation took 10 hours, and the patient could be discharged from the ICU after 48 hours. After the drains had been removed, the patient was transferred to the general ward. Postoperative course was uneventful. According to post-operative control echocardiography and MSCT, the patient showed no abnormalities and her initial symptoms had been relieved. The patient was discharged 13 days after surgery.
