Median follow-up duration of 41 months (range 4 to 126)

*

Less than 48 hours after surgery

Δ

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
