Laser speckle contrast imaging (LSCI) has emerged as a promising tool for assessment of vessel flow during neurosurgery. We aimed to investigate the feasibility of visualizing vessel flow in the macrocirculation with a new fully microscope-integrated LSCI system and assess the validity and objectivity of findings compared with fluorescence angiography (FA). ⋯ Fully microscope-integrated LSCI is feasible and has a high potential for clinical utility. Because of its characteristics, LSCI can be viewed as a full-field visual micro-Doppler that can be used as a complementary method to FA for assessing vessel flow during neurosurgery. Despite technical limitations related to the early development phase of the fully microscope-integrated system, we demonstrated reasonable validity and objectivity of findings compared with FA. Further research and refinement of the system may enhance its value in neurosurgical applications.

Systemic Hypertension and Postoperative Symptomatic Spinal Epidural Hematoma: A Scoping Review.
Postoperative symptomatic spinal epidural hematoma (PSSEH) is a serious complication of spinal surgery that is associated with significant morbidity. Studies suggest that hypertension is a risk factor for the development of PSSEH. The aim of this review was to evaluate the literature reporting associations between hypertension and PSSEH. ⋯ The overall quality of evidence was low because of the retrospective nature of the studies, heterogeneity, and lack of precision in reporting. Despite the limitations of the current evidence, our findings could be important in establishing preoperative BP targets for elective spine surgery and inform perioperative clinical decision-making, while allowing consideration of risk factors for PSSEH. Well-controlled studies are required to investigate further the relationship between BP and PSSEH.
