Review Case Reports
Severe neuromuscular scoliosis implicated by dysfunction of intrathecal Baclofen pump. Case report and literature review.
Complex spinal deformities are a common issue in pediatric patients with an underlying neurologic diagnosis or syndrome. Management of neuromuscular scoliosis is an awesome responsibility, because these patients present with the most challenging pathologies of the deformed spine. Along with surgical correction of the underlying deformity, an intrathecal baclofen (ITB) pump is considered effective in managing the associated spasticity. ⋯ The association of cerebral palsy and relevant disorders with the relentless progression of scoliosis is analyzed, along with the possible offending mechanisms. The efficacy of an ITB pump in controlling intractable spasticity associated with neuromuscular scoliosis is reviewed, as well as its potential to accentuate the clinical progression of neuromuscular scoliosis. Although this is an extremely infrequent situation, we must always bear in mind the possibility that malfunction of an ITB pump could be related to obstruction of CSF flow, owing to the extreme severity of the curves established during the course of, most likely untreated, neuromuscular scoliosis.

Multicenter Study
Transcirculation Approach for Endovascular Embolization of Intracranial Aneurysms, Arteriovenous Malformations and Dural Fistulas: A Multicenter Study.
Unfavorable anatomy can preclude traditional anterograde endovascular interventions. Transcirculation approaches, which consist of primary catheterization of a target artery from the contralateral side or opposite cerebral circulation, can provide alternative pathways for successful treatment of these patients. We aimed to assess the safety, efficacy, and outcomes of endovascular embolization through transcirculation approaches. ⋯ Transcirculation approaches seem to be safe and effective in the treatment of IAs, dAVFs, and AVMs. The most common indication for a transcirculation approach is the presence of a difficult angle to access the target lesion and occlusion of the parent artery.

Neurenteric cyst (NEC) is a rare intradural spinal tumor, but a correct preoperative diagnosis remains challenging. A misdiagnosis of arachnoid cyst (AC) often leads to conflicting surgical management and significantly higher recurrence. ⋯ NECs must be differentiated from ACs because they are different diseases and require different surgical management. In cases with clear cystic content, however, the diagnosis is likely to be AC, but a thick cystic wall and structural adhesions should suggest the differential diagnosis of NEC. Gross total removal of NECs should be attempted to reduce NEC recurrence.

Review
Artificial Discs in Cervical Disc Replacement: A Meta-Analysis for Comparison of Long-term Outcomes.
Cervical disc replacement (CDR) has emerged as an alternative to anterior cervical discectomy and fusion for the surgical treatment of degenerative cervical disc disease. Although comparison of the 2 techniques has been studied in the literature, a thorough assessment of all artificial discs between each has not been performed. The objective of the present study was to examine the long-term outcomes of 5 artificial discs. ⋯ The results of the present meta-analysis indicate that surgical and clinical outcomes may differ among different CDR devices. These findings may assist surgeons in tailoring their decision making to specific patient profiles. Future multicenter efforts are needed to validate associations found in this study.

Comparative Study
Predicting In-Hospital Complications Following Anterior Cervical Discectomy and Fusion: A Comparison of the Elixhauser and Charlson Comorbidity Measures.
The objective of this study was to determine the ability of the Elixhauser Comorbidity Index (ECI) and Charlson Comorbidity Index (CCI) to predict postoperative complications after anterior cervical discectomy and fusion (ACDF). ⋯ The ECI was superior to the CCI in predicting 6 of 15 complications in this study. Both are excellent tools for predicting mortality after ACDF.
