2.4 Treatment results
There were 2 hospitalized deaths in the whole group, and 1 case had a large area of cerebral infarction after one-stage operation. In one case, the esophageal fistula was large during the second-stage operation and could not be repaired. Part of the esophagus was removed and septic shock occurred after the operation. The remaining 4 patients recovered well after the operation and were discharged. During the follow-up period, all the surviving patients had returned to normal living conditions without recurrence of infection and esophageal fistula. CT angiography of the whole aorta showed no obvious abnormalities in the morphology and blood flow of the bypass graft, and no obvious lesions in the aortic stump (Figure 4).
