- The incidence of postoperative cerebral hyperperfusion syndrome [ Time Frame: postoperative day 15 ]Cerebral hyperperfusion syndrome was defined if all the following four criteria were met: i) new development of postoperative focal neurological deficits, ii) a delayed neurological deficits which were not shown in the immediate postoperative period; iii) postoperative reversible neurological deficits which were completely resolved within 15 days after operation; iii) neither definite haematomas nor definite acute infarction on a brain CT scan, on diffusion magnetic resonance imaging, or both.
- The incidence of a new onset postoperative cerebral ischemia [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks. ]cerebral ischemia is diagnosed by clinical symptoms and radiologic imaging (CT or MRI).
- The incidence of a new onset postoperative brain hematoma [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks. ]postoperative brain hematoma is diagnosed by clinical symptoms and radiologic imaging (CT or MRI).
- The incidence of unrecovered neurological deficit [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 weeks. ]the incidence of postoperative neurological symptoms which persisted or not fully recovered until the patient's discharge.
