Many studies demonstrate that the accuracy of freehand catheter placement for cerebrospinal fluid drainage is suboptimal. The aim of placement should be a single pass with a free-floating catheter tip in the intended position. The objective of this study was to achieve an accurate and user-friendly system for three-dimensional (3D) ultrasound-navigated catheter placement through a regular burr hole. ⋯ 3D ultrasound with the described setup is a promising technique for accurate, fast, and user-friendly navigated placement of catheters for cerebrospinal fluid diversion.

Effective treatments for acute neurologic illness and injury are lacking, particularly for spinal cord injury (SCI). The very structure of clinical trials may be contributing to this because assumptions made during trial planning preclude additional learning within residual important areas of uncertainty, such as dose, timing, and duration of treatment. Adaptive clinical trials offer potential solutions to some of the factors that may be slowing the pace of discovery. ⋯ Within this review, we describe the structure of flexible adaptive clinical trial designs, the process by which they are developed and conducted, and potential opportunities and drawbacks of these approaches. We must accept that there are some uncertainties that remain when both exploratory and confirmatory trials are designed. The process by which teams carefully consider which uncertainties are most important and most likely to potentially compromise the ability to detect an effective treatment can lead to trial designs that are more likely to find the right treatment for the right population of patients.

Large vessel occlusions with heavy clot burden are less likely to improve with intravenous (IV) thrombolysis alone. The purpose of this study was to show whether a combination of IV thrombolysis and endovascular therapy was superior to endovascular treatment alone. ⋯ Combining IV thrombolysis with endovascular therapy resulted in similar outcome, revascularization, sICH, and mortality rates compared with endovascular therapy alone. Prospective clinical studies comparing both treatment strategies in acute ischemic stroke are warranted.

The aim of this study was to examine the solid bone fusion rates between Plasmapore-coated titanium cages (PPC group) and non-Plasmapore-coated titanium cages (N-PPC group) in patients who received anterior cervical decompression and fusion (ACDF). ⋯ Plasmapore-coated titanium cages enabled more rapid solid bone fusion. We suggest that these types of cages might help to reduce postoperative radiograms.

To identify deficiencies leading to readmissions to the University of Florida Neurosurgery Service by using the Institute for Healthcare Improvement STate Action on Avoidable Rehospitalizations Readmissions diagnostic tool and to report the opinions of patients, their families, and health care providers. ⋯ Systematic patterns and common themes associated with patient readmissions were identified for a neurosurgical service. These findings are now being used to implement changes in discharge planning.
