Cranial dural arteriovenous fistulas (dAVFs) are rare acquired neurovascular disorders that have the potential to profoundly alter the local and global cerebral venous drainage. Factors such as location, angioarchitecture, degree of shunting, and mode of presentation all appear to have some bearing on the natural history of dAVFs, which can vary from almost entirely benign to life-threatening. ⋯ It is only through a thorough understanding of their behavior and the treatment options available that we will be able to deliver tailored treatment to the correct dAVF and the correct patient. We aimed to provide an up-to-date summary of the reported data on the natural history and predictors of aggressive behavior for cranial dAVFs in general, followed by site-specific management considerations.

Review Meta Analysis
Baseline Risk Factors for Prolonged Opioid Use Following Spine Surgery: Systematic Review and Meta-Analysis.
To conduct a comprehensive systematic review and meta-analysis of current retrospective cohort studies to identify significant preoperative risk factors for prolonged postoperative opioid use following spine surgery. ⋯ Several patient-level factors may play a role in the tendency to persistently use opioids after spine surgery. By preoperatively identifying these characteristics, clinicians may be better able to identify patients who are at risk and employ methods to mitigate potential long-term opioid use.

Randomized Controlled Trial Multicenter Study
Angulation towards coronal convexity measure and catheter length indication improves the quality of ventricular catheter placement - a smartphone-assisted guidance technique.
Accurate placement of a ventricular catheter (VC) is crucial to reduce the risk of shunt failure. In the randomized, prospective, multicenter GAVCA (guided application of ventricular catheters) trial, which evaluated the quality of VC placement, the subgroup of patients with detailed length-marked VCs (dVCs) reflected a difference in the primary endpoint of optimal VC placement compared with the subgroup of patients with simplified length-marked VCs (sVCs). The objective of the present analysis was to compare the dVC and sVC groups and the smartphone-assisted guidance technique (GA) with the standard freehand technique (FH) for VC placement. ⋯ The results from the present analysis suggest that the combination of a GA technique and the use of a dVC will improve the rate of accurate VC placement. Compared with the FH technique, patient safety was increased by the reduction of unsuccessful VC placement attempts using the GA technique and dVCs.
