Median follow-up duration of 41 months (range 4 to 126)
Less than 48 hours after surgery
Post-surgical infarctions account for 2 of 5 of the new focal deficits due to surgery. Only 1 patient had persistent deficit on long-term follow-up
1 of 2 Hygromas account for 1 of the 5 new focal deficits due to surgery
Greater than 48 hours after surgery
Functional outcome according to the modified Rankin Scale
One patient had decline in independence due to unrelated comorbidities
