Robot-Assisted Thoracoscopic Clipping of a Mediastinal Bronchial Artery Aneurysm

Bronchial artery aneurysms (BAAs) are rare vascular anomalies categorized as mediastinal, intrapulmonary, or combined. Although they are typically asymptomatic, rupture can result in life-threatening complications necessitating immediate intervention, commonly by transcatheter arterial embolization. We describe a 59-year-old woman presenting with intermittent hemoptysis lasting >1 month. Computed tomography revealed a 12 × 8 × 7-mm mediastinal BAA located in the aortopulmonary window. Successful aneurysm resection was performed by robot-assisted thoracoscopic surgery clipping, with minimal blood loss and uneventful postoperative recovery. Robot-assisted thoracoscopic surgery clipping is an effective alternative for anatomically complex BAAs challenging for conventional embolization.
