“…In the previous study 10 , there were 68% perioperative AIS patients receiving cardiovascular surgery and 12% receiving neurosurgery, while we had only 29% patients in the perioperative AIS group, who had undergone cardiovascular procedure. In studies of the therapeutic efficacy of EVT in in-hospital and community-onset AIS patients, the former generally had poorer recovery and higher mortality, which was correlated with the modified Charlson Comorbidity Index (mCCI), incorporating 7 comorbidities, age, diabetes, anemia, active cancer, myocardial infarction, congestive heart disease, and ulcer disease into the model 11 28 . We further suppose that the widely used mini-invasive surgery in our studying cohort may favor the functional recovery of perioperative AIS patients.…”
