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).
