The study compares surgical outcomes between patients with stent-related type A dissection (SRTAD) and those with spontaneous type A dissection (STAD).
SRTAD patients had longer selective cerebral perfusion and cross-clamp times during surgery, and a higher in-hospital mortality rate, but no significant differences in other postoperative complications or mid-term outcomes compared to STAD patients.
Findings suggest that while SRTAD carries higher risks during hospitalization, the long-term survival rates and overall recovery after surgery are similar to those for STAD.
