“…The first issue involves the types of vascular substitutes appropriate for training. Gauze fibers, 3) silicone tubes, 4,6) cadaveric materials, 9) animal vessels, 2) and perfused animal vessels 1) have all been used in training. Artificially pulsatile or perfused arteries in models can create a relatively realistic situation.…”

“…Artificially pulsatile or perfused arteries in models can create a relatively realistic situation. 1) The second issue is how to reproduce situations of similar technical difficulty as real vascular anastomosis. To date, training methods for techniques of microvascular anastomosis have mainly been for resident neurosurgeons who have recently started…”

Models of the brain and skull were developed using a selective laser sintering method for training in the procedures of deep microvascular anastomosis. Model A has an artificial skull with two craniotomies, providing fronto-temporal-subtemporal and suboccipital windows. The brain in Model A is soft and elastic, and consists of the brainstem and a hemispheric part with a detailed surface. Rehearsals or training for anastomosis to the insular part of the middle cerebral artery, superior cerebellar artery, posterior cerebral artery, and posterior inferior cerebellar artery can be performed through the craniotomies. Model B has an artificial skull with a bifrontal craniotomy and an artificial brain consisting of the bilateral frontal lobes with an interhemispheric fissure and corpus callosum. Rehearsals or training for anastomosis of the callosal segment of the anterior cerebral artery can be practiced through this craniotomy. These realistic models will help to develop skills for deep vascular anastomosis, which remains a challenging neurosurgical procedure, even for experienced neurosurgeons.

“…Artificially pulsatile or perfused arteries in models have recently been reported to create relatively realistic situations. [131318] However, these are neither convenient nor practical for individual use in daily practice, and a simple and accessible model that can be set up rapidly under safe and hygienic conditions and with no involvement of ethical questions is required. Our vascular prosthetic tube appears to have all of these characteristics, and trainees will be able to practice more easily and frequently under realistic suturing/handling conditions than with other non-biological vascular materials.…”

Background:Microvascular anastomosis is a challenging neurosurgical technique that requires extensive training for one to master it. We developed a new vascular model (KEZLEX, Ono and Co., Ltd., Tokyo, Japan) as a non-animal, realistic tool for practicing microvascular anastomosis under realistic circumstances.Methods:The model was manufactured from polyvinyl alcohol hydrogel to provide 1.0–3.0 mm diameter (available for 0.5-mm pitch), 6–8 cm long tubes that have qualitatively similar surface characteristics, visibility, and stiffness to human donor and recipient arteries for various bypass surgeries based on three-dimensional computed tomography/magnetic resonance imaging scanning data reconstruction using visible human data set and vessel casts.Results:Trainees can acquire basic microsuturing techniques for end-to-end, end-to-side, and side-to-side anastomoses with handling similar to that for real arteries. To practice standard deep bypass techniques under realistic circumstances, the substitute vessel can be fixed to specific locations of a commercially available brain model with pins.Conclusion:Our vascular prosthesis model is simple and easy to set up for repeated practice, and will contribute to facilitate “off-the-job” training by trainees.

“…Several other infusion models have since been developed, using similar pulsatile perfusion methods or other microvascular training models such as a chicken wing. [43][44][45][46][47][48][49][50][51][52][53][54] Spine surgery has benefited tremendously from the use of cadaver models for instrumentation. Among the numerous studies conducted, animal and human cadaveric spine models have been used to compare instrumentation systems, determine safe pedicle screw placement and the accuracy of image guidance in the operating room, develop minimally invasive and robotic techniques, study traumatic spine injury, and conduct biomechanical studies in the laboratory.…”

The Birth and Evolution of Neuroscience Through Cadaveric Dissection

Although interest in the art of dissection and vivisection has waxed and waned throughout the ages, the past century has seen it accepted as commonplace in medical schools across the country. No other practice in medicine has contributed more to the understanding of neuroanatomy and the neurosciences as dissection of the human cadaver, the origins of which are widely documented to have been in Alexandrian Greece. This article chronicles the fascinating and often controversial use of dissection and vivisection in these fields through the ages, beginning with Herophilus of Alexandria, among the first systematic dissectors in the history of Western medicine. The authors comment on its role in the development of modern neurosurgery and conclude with remarks about use of this educational tool today in the United States.
