Impact of Tubular Retractor-Assisted Transsulcal Minimal Invasive Parafascicular Approach for Deep-Seated Lesions in Cortical Vascularization

Abstract AIMS Assess the impact of tubular retractor-assisted transsulcal minimal invasive parafascicular approaches(tsMIPS) in cortical vascularization using indocianin green angiography(ICGA) during removal deep-seated cerebral tumours. METHOD Single-centre prospective cohort study patients with lesions – distance to nearest sulcus > 10mm - where ICGA was performed. Zeiss FLOW800 Software used analyse following variables delay time, speed, time peak and rise before after insertion retractor (NICO BrainPath). RESULTS 13 were enrolled. 60 regions-of-interest analysed. The most common pathology high grade glioma (69%). average depth tumours 34,2mm (23– 45mm) time-under-retraction 166mins (45-280 mins). vascular pattern before-after was: increase on rising (present 8 patients) a decrease speed 7 patients). Two had mayor neurological deficit surgery. Both same flow an indifference. CONCLUSION This is first assessing tsMIPS lesion resection. is: speed. two who presented injury shared (increase indifference delay).
