Abstract Only few studies have assessed brain shift caused by positional change. This study aimed to identify factors correlated with a large postneurosurgical (PBS). Sixty-seven patients who underwent neurosurgical procedures had upright computed tomography (CT) scan using settings similar those of conventional supine CT. The presence clinically significant PBS, defined as ≥ 5 mm change, was evaluated. clinical and radiological findings were investigated associated larger PBS. As result, twenty-one univariate analysis showed that supratentorial lesion location, intra-axial type, craniectomy procedure, residual intracranial air the predictors Based on multivariate analysis, procedure ( p < 0.001) volume = 0.004) In sub-analysis post-craniectomy patients, PBS in site parenchymal injury. A area long interval from extent conclusion, undergo can present predisposing are craniectomy, injury, skull defect area, craniectomy. These contribute safe mobilization among risk assessment sinking skin flap syndrome.
