Laminoplasty causes destruction of the posterior musculoligamentous complex, which may result in cervical kyphosis, or more commonly loss of cervical lordosis (LOCL). In this study, we evaluated the role of various preoperative radiologic parameters in predicting not only the LOCL/kyphosis but also the functional outcomes in the form of change in Oswestry Disability Index (ODI) score following laminoplasty. ⋯ We have found that the chances of significant LOCL is determined by an interplay of preoperative Cobb angle, T1S, and dynamic extension reserve.

Endovascular embolization with transvenous sinus preservation using balloon is at present the preferred modality for dural arteriovenous fistulas involving venous sinuses (sagittal, transverse, and sigmoid) with potential drainage function. The aim of the study was to evaluate the necessity and medium-term efficacy of this technique. ⋯ Transvenous balloon protection technique maintains sinus patency in most cases, and preoperative stenosis increases the probability of sinus occlusion. De novo fistula is related to sinus occlusion during the follow-up.

Preoperative laboratory tests are varied in their administration among physicians, and previous studies have published conflicting reports on their utility. Anterior cervical discectomy and fusion (ACDF) is a commonly performed spine surgery, and patients often undergo preoperative testing. We sought to assess the relationship between preoperative laboratory values and risk for adverse postoperative outcomes after ACDF. ⋯ Our analyses indicate that abnormal preoperative laboratory values are associated with increased risk for adverse outcomes after elective ACDF and can be used in predictive analyses of outcomes.

Traditionally, full spine standing radiographs have been the reference standard for diagnostic imaging in adolescent idiopathic scoliosis (AIS). However, recent advances in diagnostic imaging have the potential to reduce radiation exposure and preserve the image quality and utility. ⋯ As such, these emerging techniques might prove beneficial in diagnosing and monitoring AIS and its progression, without high levels of continued radiation exposure. To understand the historical perspective and current state of advanced imaging techniques for AIS, a search of PubMed electronic database was conducted to identify studies that had examined these new techniques in the diagnosis of idiopathic scoliosis in children and adolescents.

Surgical Versus Endovascular Management of Ruptured and Unruptured Intracranial Aneurysms: Emergent Issues and Future Directions.
Ideal management of unruptured intracranial aneurysms (UIAs) and ruptured intracranial aneurysms (RIAs) is a controversial issue. Over the last few decades, a significant paradigm shift has occurred away from open microsurgical clipping toward endovascular coil embolization. Multiple studies have been performed with mixed results. ⋯ Here we provide a review of some of the major studies comparing open surgery versus endovascular treatment for both RIAs and UIAs to distill their key findings and corresponding implications for clinical practice. We relate these research results to our institution's experience with RIAs and UIAs and describe our approach to treatment of these conditions. Finally, we discuss implications of the paradigm shift for both open and endovascular surgery, including educational initiatives directed toward preserving important microsurgical tenets in the setting of diminishing surgical volume.
