Limitations and strengths
This study’s limitations lay in its retrospective nature and patient population’s heterogeneity, with study data solely derived from patients’ hospital charts. We also lacked laboratory data or imaging reports enabling us to identify subclinical abnormalities. Moreover, the neurological assessment was solely based on clinical findings followed-up by imaging, without any established imaging protocol applied. The next necessary step is now a prospective study using exhaustive data collection according to a pre-established protocol to fully assess this surgery and perfusion technique.
