Background:Nowadays, the sitting position has lost favor among neurosurgeons partly due to assumptions of increased complications, such as venous air embolisms (VAEs) and hemodynamic disturbances. The aim of our study is to describe the importance of some anesthetic considerations and the utility of antigravity trousers as well, together with a skillful neurosurgery and an imperative proper teamwork, in order to prevent the risk of severe VAE during pineal region surgery. We routinely use them for the variant of the sitting position we developed, the “praying position.”Methods:A retrospective review of 51 pineal lesions operated on in the “praying position” using antigravity trousers was carried out. In the “praying position” the legs of the patient are kept parallel to the floor. Hence, antigravity trousers are used to generate an adequate cardiac preload.Results:VAE associated to persistent hemodinamic changes was nonexistent in our series. The rate of VAE was 35.3%. VAEs were diagnosed mainly by monitoring of the end-tidal CO2 (83.33%). A venous system lesion was the cause in most of the cases. When VAE was suspected, an inmediate reaction based on a good teamwork was imperative. No cervical spine cord injury nor peripheral nerve damage were reported. The average microsurgical time was 48 ± 33 min.Conclusions:The risks of severe VAE during pineal region surgery in the “praying-sitting position” may be effectively prevented by some essential anesthetic considerations and the use of antigravity trousers together with a skillful neurosurgery, and an imperative proper teamwork.

Background:Neurosurgical educational programs and courses are helpful to improve the quality of training. Moreover, nowadays, online activities may represent a very useful tool to globally enhance neurosurgical education. The “Hernesniemi's 1001 and more microneurosurgical videos” project aims to show the microsurgical style developed by the senior author and his TEAMs in more than 40 years of experience.Methods:More than 1100 high-definition videos of microneurosurgical operations performed by the senior author were carefully edited. These videos illustrate the philosophy of “simple, clean, fast and preserving the normal anatomy” while offering a step by step guide of different neurosurgical procedures.Results:All the aforementioned material is well organized in an electronic videobook, freely available in Surgical Neurology International. The book also includes comments of great current neurosurgeons and writings of the authors and editors.Conclusion:We are sure that our project will be able to instill in and spread across the neurosurgical community the microneurosurgical style of the senior author, thus representing an efficient educational tool for surgeons all around the world.

“Squeeze Maneuver” Assisted by Indocyanine Green Videoangiography: Simple Technique to “Resuscitate” Partially Occluded Bridging Veins During Microneurosurgical Operations

Abstract: The "squeeze maneuver" assisted by ICGV represents a safe, clean, fast, and even cheap method for restoring the flow of partially occluded bridging veins during microneurosurgical operations.
