“…This elucidates why both techniques are used by neurosurgeons. 5,11,20 The time taken to perform the bypass Ensuring that the vessel is closed timeously in a bypass procedure is stressful for the surgeon as delays are associated with adverse brain effects. However, the performance and quality of the bypass are more relevant than stitching the vessels within the stipulated timeframe (of 20 minutes).…”

“…Vital steps need to be taken to ensure the quality of vascular anastomosis during bypass surgery. [1][2][3][4][5][6][7][8][9][10][11] It is critical to ensure that the time taken to minimise blood flow during the procedure is as brief as possible as this is a significant source of stress for the neurosurgeon 12,13 and can impact on the quality of suturing.…”

Advances in imaging and computer technology have led to the development of different simulation models to complement traditional surgical training. Sophisticated virtual reality (VR) simulators with haptic feedback and impressive imaging technology have provided novel options for training in neurosurgery. Breakthrough training simulation using 3D printing technology holds promise for future simulation practice, proving high-fidelity patient-specific models to complement residency surgical learning.

“…Notably, novel methods that involve multiple senses, such as sight, hearing, and tactile sensation, have been shown to greatly enhance learning and education. 11,17 Thus, the Congress of Neurological Surgeons has called for the incorporation of neurosurgery simulation training into residency curriculum to maximize proficiency in the most efficient way. 9 Cerebrovascular bypass surgery (CBS) remains a critical neurosurgical procedure to augment or restore cerebral circulation in the treatment of some conditions, such as moyamoya disease, 15,20 giant/complex aneurysms, and skull base tumors, 8,26,28,29 for which there are no effective alternatives.…”

OBJECTIVE Cerebrovascular bypass surgery is a challenging yet important neurosurgical procedure that is performed to restore circulation in the treatment of carotid occlusive diseases, giant/complex aneurysms, and skull base tumors. It requires advanced microsurgical skills and dedicated training in microsurgical techniques. Most available training tools, however, either lack the realism of the actual bypass surgery (e.g., artificial vessel, chicken wing models) or require special facilities and regulations (e.g., cadaver, live animal, placenta models). The aim of the present study was to design a readily accessible, realistic, easy-to-build, reusable, and high-fidelity simulator to train neurosurgeons or trainees on vascular anastomosis techniques even in the operating room. METHODS The authors used an anatomical skull and brain model, artificial vessels, and a water pump to simulate both extracranial and intracranial circulations. They demonstrated the step-by-step preparation of the bypass simulator using readily available and affordable equipment and consumables. RESULTS All necessary steps of a superficial temporal artery-middle cerebral artery bypass surgery (from skin opening to skin closure) were performed on the simulator under a surgical microscope. The simulator was used by both experienced neurosurgeons and trainees. Feedback survey results from the participants of the microsurgery course suggested that the model is superior to existing microanastomosis training kits in simulating real surgery conditions (e.g., depth, blood flow, anatomical constraints) and holds promise for widespread use in neurosurgical training. CONCLUSIONS With no requirement for specialized laboratory facilities and regulations, this novel, low-cost, reusable, high-fidelity simulator can be readily constructed and used for neurosurgical training with various scenarios and modifications.
