Multicenter Study Observational Study
Surgery for herniated lumbar disc in daily tobacco smokers: A multicenter observational study.
To compare clinical outcomes at 1 year following single-level lumbar microdiscectomy in daily tobacco smokers and nonsmokers. ⋯ Nonsmokers reported a greater improvement in ODI at 1 year following microdiscectomy, and smokers were less likely to experience an MIC. Nonetheless, significant improvement was also found among smokers.

Posterior-anterior spondylodesis is often used to stabilize the spine in various pathologies. The anterior procedure is often performed via thoracoscopy. It is unclear whether the anterior procedure should be performed immediately after posterior instrumentation or after the patient has convalesced. This retrospective study compared perioperative safety and morbidity in 1-stage versus 2-stage posterior-anterior fusion surgery with a thoracoscopic anterior approach. ⋯ One-stage stabilization was as safe as 2-stage stabilization and associated with shorter hospitalization. Greater pain after the 1-stage procedure, which resolved 30 days after surgery, reflects the fact that 2-stage patients already had pain relief when they underwent thoracoscopy.

Comparative Study
Comparison of chronic Dysphagia in Standalone versus Conventional Plate and Cage Fusion.
Standalone cages have gained popularity because of their ease of implantation, reduced operating time, and lower profile compared with traditional plate and cage systems. The aim of this study was to compare the risk of chronic dysphagia between those who undergwent anterior cervical discectomy and fusion (ACDF) with traditional plating techniques and those who underwent standalone procedures. ⋯ Despite similar mean DDI scores, patients who undergo anterior cervical discectomy with a plate-cage may be at a higher risk for chronic dysphagia than are those with a standalone approach, but further studies with larger sample sizes are necessary to establish this relationship with greater confidence.

Treatment of ruptured posterior circulation dissecting aneurysms is technically challenging with potentially high morbidity and mortality. We sought to assess the safety and feasibility of using a flow-diversion device (FDD) and a specific acute antiplatelet aggregation protocol in the management of ruptured dissecting aneurysms. ⋯ Treatment of dissecting posterior circulation aneurysms with FDDs is feasible and a potential alternative to deconstructive techniques.

This study was performed to evaluate the efficiency of Gamma Knife surgery (GKS) on reducing recurrence of World Health Organization (WHO) grade II meningiomas after surgery and to define the risk factors associated with tumor recurrence/progression and patient's death. ⋯ There was no significant PFS or OS benefit for patients with WHO grade II meningiomas treated with adjuvant/salvage GKS postoperatively. Convexity meningiomas with gross total resection tended to benefit PFS. We suggest trying to achieve maximum safe gross total resection for patients with WHO grade II meningiomas, then following up closely.
