From knife to needle - the trend of vascular neurosurgery in Belgium.

Introduction: The management of neurovascular pathologies has changed globally over the last few decades. Endovascular treatments are increasing, and fewer surgical procedures are performed.

Research Question: Evaluate the evolution of vascular neurosurgery in Belgium over the last 30 years and compare with other countries.

'What's in a name', a systematic review of the pterional craniotomy for aneurysm surgery and its many modifications with a proposal for simplified nomenclature.

Background: The pterional or frontosphenotemporal craniotomy has stood the test of time and continues to be a commonly used method of managing a variety of neurosurgical pathology. Already described in the beginning of the twentieth century and perfected by Yasargil in the 1970s, it has seen many modifications. These modifications have been a normal evolution for most neurosurgeons, tailoring the craniotomy to the patients' specific anatomy and pathology.

Nonprogrammable Shunts for Communicating Hydrocephalus and Three-Dimensional Volumetry: A Retrospective Analysis.

Objective: Although the use of different types of valves has been extensively studied in shunt surgery for communicating hydrocephalus (cHC), a consensus about the valve type remains absent. The objective of this study is to evaluate our results with the primary placement of nonprogrammable valves (NPVs) for this indication.

Methods: We retrospectively analyzed all first NPVs implanted between 2014 and 2020 for cHC.

Pituitary carcinoma - case series and review of the literature.

Although pituitary adenomas (PAs) account for 15% of intracranial tumors, pituitary carcinomas (PCs) are a rare entity. Most commonly, PCs evolve from aggressive PAs invading the surrounding structures and eventually leading to metastatic lesions. Due to the low incidence, the diagnosis and treatment remains challenging.
