Review Meta Analysis
Hemorrhage, seizures, and dynamic changes of familial versus non-familial cavernous malformation: systematic review and meta-analysis.
Cerebral cavernous malformations (CCMs) may be familial or nonfamilial. This systematic review compared the natural history of CCMs in familial compared with nonfamilial cases. ⋯ Familial CCMs show higher dynamic changes than nonfamilial cases. However, the presence of actual dynamic changes needs further assessment in nonfamilial cases. CCMs demonstrate a low incidence of seizure. First-time seizure increases the chance of recurrent seizure. Seizure rate based on the location and type of the lesion should be investigated further.

Review Meta Analysis
Accuracy of Current Techniques for Placement of Pedicle Screws in the Spine: A Comprehensive Systematic Review and Meta-Analysis of 51,161 Screws.
Pedicle screws (PSs) are routinely used for stabilization to enhance fusion in a variety of spinal diseases. Although the accuracy of different PS placement methods has been previously reported, most of these studies have been limited to 1 or 2 techniques. The purpose was to determine the current accuracy of PS placement among 4 modalities of PS insertion (freehand [FH], fluoroscopy-assisted [FA], computed tomography navigation-guided [CTNav], and robot-assisted [RA]) and analyze variables associated with screw misplacement. ⋯ The OP data show that CTNav has the highest PS accuracy rates. Thoracic PSs were associated with lower accuracy rates; however, RA showed fewer breaches in the thoracic spine compared with FH and FA. Given the heterogeneity among studies, further standardized and comparative investigations are required to confirm our findings.

Multicenter Study
Treatment of blood blister-like aneurysms with stent-assisted coiling: a retrospective multicenter study.
To clarify safety and efficacy of stent-assisted coiling for treatment of blood blister-like aneurysm (BBA) in a multicenter experience. ⋯ Our data support the use of overlapping (≥2) stents combined with coiling as a safe and effective therapeutic modality for BBA. Overlapping (≥2) stents may provide higher obliteration rate, lower recurrence rate, and lower perioperative hemorrhagic risk in treatment of BBA.
