Review Meta Analysis
Comparison of bypass and non-bypass surgical treatments for internal carotid artery blood blister-like aneurysms: a meta-analysis of efficacy, safety and outcomes.
The optimal surgical strategy for treating internal carotid artery (ICA) blood blister-like aneurysms (BBAs) has remained unclear. Although some have preferred bypass surgery, others have favored less-demanding surgical methods. The aim of the present meta-analysis was to assess the efficacy, safety, and outcomes of bypass and non-bypass surgical methods when intended as primary treatment of ICA BBAs. ⋯ For surgeons who use both bypass and non-bypass surgical strategies, the 2 methods seemed comparable in terms of the outcomes of interest, although the bypass technique appeared superior. However, comparisons with studies reporting bypass as the uniquely preferred technique have indicated that specialization in, and preference for, the bypass procedure has been associated with more favorable outcomes.

Surgical intervention for chronic subdural hematoma (cSDH) in the elderly population remains a clinical challenge given that associated morbidity and outcomes do not always equate radiographic success with clinical success. Our objective was to compare outcome measures of 2 age groups of patients undergoing surgical intervention for cSDH evacuation and to perform a systematic review of the literature related to this topic. ⋯ The aged cohort had worse outcomes than the younger cohort as determined by mRS score at discharge and 3 months. A systematic review of outcomes is provided with limited meta-analysis because of the heterogenous nature of outcome reporting and the observational design of previous studies. Further studies with standardized reporting and long-term follow-up are warranted to further study outcomes in this increasing population.

Although O-arm-based navigation (ON) has been considered a better choice than the conventional freehand (FH) technique for spine surgery, clinical evidence showing the accuracy of ON compared with the FH technique is limited. The purpose of this study was to evaluate the accuracy of pedicle screw insertion under ON compared with the FH technique. ⋯ Compared with conventional methods, navigation provides greater accuracy in the placement of pedicle screws, accelerates the insertion, and reduces the complications associated with screw insertion. However, it may increase exposure time to radiation, which may harm the patient's or surgeon's health.
