Intraoperative fluorescein detection has been used in the fields of vascular and oncologic neurosurgery since 1948. Modifications of the optics in order to enhance the fluorescence contrast under microscopic view have been developed by many authors. The industries, during the past 10 years, provided commercial high-cost optimized apparatuses. Reviewing the literature, we found that the prototypical techniques were definitely inexpensive but lacked reliability, reproducibility, and standard legal norms. ⋯ Our results show a good distinction of fluorescein-stained structures, with overall acceptable operating light conditions.

Venous thromboembolism (VTE) is a serious complication after intracranial meningioma surgery. To what extent systemic prophylaxis with pharmacotherapy is beneficial with respect to VTE risk, or associated with increased risk of bleeding and postoperative hemorrhage, remains debated. The current study aimed to clarify the risk/benefit ratio of prophylactic pharmacotherapy initiated the evening before craniotomy for meningioma. ⋯ There is no benefit of routine preoperative LMWH starting before intracranial meningioma surgery. Neither could we for primary outcomes detect a significant increase in clinically relevant postoperative hematomas secondary to this regimen. We suggest that as needed perioperative administration of LMWH, reserved for patients with excess risk because of delayed mobilization, is effective and also appears to be the safest strategy.

Pre-Treatment of Anxiety Prior to Cervical Spine Surgery Improves Clinical Outcomes: A prospective Single Institutional Experience.
Affective disorders such as depression and anxiety have been shown to contribute to inferior outcomes after spine surgery. A high baseline level of anxiety is associated with refractory postoperative pain and patient dissatisfaction with surgery. The aim of this prospective study is to assess whether the pretreatment of anxiety before spine surgery improves patient reported outcomes 1-year after an anterior cervical discectomy and fusion (ACDF) procedure. ⋯ Our study demonstrates that pretreatment of anxiety before cervical spine surgery results in a significant reduction in postoperative neck pain scores and may be a viable management strategy for patients with coexisting affective disorders and cervical spine pathology. Patients awaiting spine surgery should routinely be assessed for anxiety before surgery, and interventions to reduce and treat anxiety should be provided.

Surgery for acute subdural haematoma: replace or remove the bone flap?
In surgery for acute subdural hematoma (ASDH), the bone flap can be fixed onto the skull, left riding to provide partial skull decompression, or removed. This study assessed whether removing the bone flap improved outcome. ⋯ Our study concluded that removing the bone flap after ASDH evacuation was not associated with a better outcome. We recommend replacing the bone flap if brain conditions allow. Further research is required to evaluate the role of skull decompression in surgery for ASDH.

Controlled Clinical Trial
Microsurgical resection for persistent arteriovenous malformations following Gamma Knife radiosurgery : A case-control study.
To explore outcomes after microsurgery of brain arteriovenous malformations (AVMs) that failed to be obliterated by Gamma Knife radiosurgery (GKRS). ⋯ GKRS performed several years before microsurgical resection can facilitate resectability of AVMs and decrease the rate of postoperative neurologic deterioration. For patients with persistent AVMs several years after GKRS, microsurgical resection is recommended to achieve good clinical outcomes.
