Injury to cerebral venous sinuses during craniotomy procedures can cause significant blood loss or venous air embolism, potentially leading to serious morbidity or mortality. When iatrogenic sinus injuries occur, it is essential to promptly obtain hemostasis and repair the sinus defect. ⋯ The use of a reflected dural flap for closure of a widely torn sinus proved to be an effective and straightforward sinus repair strategy, with postoperative imaging demonstrating persistent patency of the sinus. The described technique may be a useful addition to any neurosurgeon's armamentarium and should be considered during cases of complex sinus injuries.

Spinal cord tanycytic ependymomas (TEs) rarely are reported because of extremely low incidence. Understanding of this disease is therefore poor. The aim of this study was to analyze the incidence and clinical, radiologic, pathologic, and prognostic features of spinal cord TEs. ⋯ Spinal cord TE is a rare subtype of ependymomas with low recurrence. Long-term survival can be expected, although poorly defined tumor border is an independent predictor of long-term outcomes. Microsurgical treatment of spinal cord TEs remains a formidable challenge due to the poorly defined border and critical neurovascular structures encasement. It is unnecessary for radical tumor resection at the cost of severe neurologic deficits.

Although extreme lateral interbody fusion (XLIF) largely provides successful indirect decompression, some patients have recurrent same-level pain and functional disability. Identifying risk factors for this failure would facilitate better patient selection and improve outcomes. The aim of this study is to identify preoperative radiographic risk factors for failure of XLIF. ⋯ Bony lateral recess stenosis is an independent predictor for failure to achieve adequate spinal decompression via XLIF and thus may benefit from undergoing direct decompression.

To observe the clinical effects of posterior percutaneous full-endoscopic cervical foraminotomy in patients with osseous foraminal stenosis. ⋯ Posterior percutaneous full-endoscopic cervical foraminotomy can accomplish full nerve root decompression and is a safe, feasible procedure. Therefore, it can be a treatment option for patients with osseous foraminal stenosis.

Comparative Study
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.
