In-hospital Complications Following Lumbar Spine Surgery in Patients with Parkinson's Disease: Evaluation of the National Inpatient Sample Database.
Previous reports suggest that patients with Parkinson disease (PD) have elevated rates of complications following spine surgery; however, these reports are limited by small patient series. In this study, we used the National Inpatient Sample (NIS) database to compare in-hospital complications following elective lumbar spine surgery in patients with a diagnosis of PD and patients without PD. ⋯ PSM analysis of the NIS database demonstrated that patients with PD are at increased risk for acute in-hospital complications and greater blood transfusion requirements than those without PD. Surgeons should be aware of the increased risks and differing requirements when treating spinal pathology in patients with PD.

Neuronavigation systems are used widely in the localization of intracranial lesions with satisfactory accuracy. However, they are expensive and difficult to learn. Therefore, a simple and practical augmented reality (AR) system using mobile devices might be an alternative technique. ⋯ The mobile AR system presents an alternative technology for image-guided neurosurgery and proves to be practical and reliable. The technique contributes to optimal presurgical planning for supratentorial lesions, especially in the absence of a neuronavigation system.

Posterior inferior cerebellar artery (PICA) aneurysms are heterogeneous, uncommon lesions that can be treated in many fashions. Many previous series have focused on a specific aneurysm subset or treatment paradigm. The aim of this study was to present a comprehensive approach for all PICA aneurysms and analyze outcomes by PICA location. ⋯ Our 5-year modern experience highlights the diversity of PICA aneurysms and the need for multimodality paradigms to treat them successfully. The AM segment has the greatest rate of recurrence. Aggressive management is warranted given that the majority of patients can have a good neurologic outcome.

The proper management of symptomatic patients with 2 or more brain metastases is not entirely clear, and the surgical outcomes of these patients undergoing multiple simultaneous craniotomies have not been well described. In this article, we describe patient outcomes after simultaneously resecting metastatic lesions through multiple keyhole craniotomies. ⋯ We present patient outcomes after simultaneously resecting metastatic brain tumors through multiple keyhole craniotomies in symptomatic patients. Our results suggest comparable outcomes and similar surgical risk compared with those undergoing resection of a single brain metastasis. Resection of multiple brain metastases may improve Karnofsky Performance Scale scores in the early postoperative period and allow patients to be weaned from steroids.

To determine the optimal proximal fusion level after long instrumented fusion to the sacrum for lumbar degenerative flat back. ⋯ If the PI is ≥50°, TL kyphosis is ≥5°, and SS is ≥20°, the UIV should be raised above T10 up to the midthoracic level. If the PI is ≥50°, SS is ≤20°, and thoracic kyphosis (TK) is normal despite TL kyphosis, the UIV should be at T10. Even if the PI is ≥50°, TK is normal, and there is no TL kyphosis, the UIV should be set at L1 or below. Regardless of the UIV, the postoperative PT should be ≤20°.
