We read the report by Çeltikçi et al in the Turkish Neurosurgery with great interest. In this single-center retrospective study, they analysed 449 intracranial meningioma patients underwent open surgery. They stated that venous thromboembolism (VTE) had been seen in 21 (4.6%) of their patients. This is an important issue because VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE), is the most common overall complication in meningioma surgery and is fatal in up to one third of patients (2)...

Backgorund Direct exposure and cannulation of superior ophthalmic vein (SOV) provides an alternative access to reach the cavernous sinus for carotid-cavernous fistula (CCF) embolization, when classic transvenous routes through inferior petrosal sinus (IPS) or facial vein are not feasible. We have used indocyanine green (ICG) videoangiography to study intraoperatively the flow inside the SOV in two cases of indirect CCF. In this paper we report the operative technique and the result of ICG videoangiographic-guided cannulation of the SOV for endovascular treatment of CCF...

The middle cerebral artery (MCA) covers a large part of the cerebral hemispheres and is therefore exposed during surgical intervention in this area. Aspects of cerebral branches tend to vary, different branching patterns can be described, and several anomalies can be observed. Knowledge of these variations and anomalies is important and can be helpful to neurosurgeons and clinicians. The aim of this study was to review the available literature on the cortical branches, branching pattern and anomalies of the MCA, to identify the gaps in the literature, and to fill these gaps by including the results of a pilot study...
