Abstract
A 74-year-old man with a history of bronchial asthma underwent total arch replacement and coronary artery bypass grafting. He was discharged without any major complications except for postoperative coughing attacks, which caused a third sternal wire fracture and partial sternal dehiscence (Figure 1A, Figures 2A and D). He was asymptomatic and without sternal instability at 3 months after surgery. However, chest radiography (CXR) revealed migration of the fractured sternal wire (Figure 1B), and computed tomography (CT) showed close contact between the edge of the fractured sternal wire and the arch branch graft to the left subclavian artery (LSCA) (Figures 2B and E).
