“…Some of the chicken wing brachial arteries have been measured to be as small as 0.6 mm. 1 Recently, we found that vessels from fresh human and bovine placentas are excellent tissue models. The fetal surface of a human placenta provides enough material for more than a dozen microsurgical anastomoses.…”

“…1 However, a limitation of these models is the less-than-ideal similarity of the tissues when compared with cerebral vessels. Small vessel diameters and the fact that the wings suffer from freezing artifacts after thawing often create difficulties with the use of poultry wing brachial arteries for practice.…”

N eurosurgical vascular cases often require complex microvascular bypass techniques, such as those used in operative corrections for moyamoya disease, 7,26,32 cerebral aneurysms, 9,13,14,19 and intracranial tumors. 30,31 Therefore, simple and accessible models for microvascular anastomosis training are increasingly essential for providing a means for refining and preserving skills. Several models, including chicken wings, 12,17 turkey wings, 1 rats, 15 human cadavers, 24,29 and plastic tubing, 22 have been proposed. However, these models are still less than ideal for various reasons, such as vessel diameter diversity, cost-effectiveness, artifacts due to storage (e.g., Low-flow and high-flow neurosurgical bypass and anastomosis training models using human and bovine placental vessels: a histological analysis and validation study obJective Microvascular anastomosis is a basic neurosurgical technique that should be mastered in the laboratory. Human and bovine placentas have been proposed as convenient surgical practice models; however, the histologic characteristics of these tissues have not been compared with human cerebral vessels, and the models have not been validated as simulation training models. In this study, the authors assessed the construct, face, and content validities of microvascular bypass simulation models that used human and bovine placental vessels. methods The characteristics of vessel segments from 30 human and 10 bovine placentas were assessed anatomically and histologically. Microvascular bypasses were performed on the placenta models according to a delineated training module by "trained" participants (10 practicing neurosurgeons and 7 residents with microsurgical experience) and "untrained" participants (10 medical students and 3 residents without experience). Anastomosis performance and impressions of the model were assessed using the Northwestern Objective Microanastomosis Assessment Tool (NOMAT) scale and a posttraining survey. results Human placental arteries were found to approximate the M 2 -M 4 cerebral and superficial temporal arteries, and bovine placental veins were found to approximate the internal carotid and radial arteries. The mean NOMAT performance score was 37.2 ± 7.0 in the untrained group versus 62.7 ± 6.1 in the trained group (p < 0.01; construct validity). A 50% probability of allocation to either group corresponded to 50 NOMAT points. In the posttraining survey, 16 of 17 of the trained participants (94%) scored the model's replication of real bypass surgery as high, and 16 of 17 (94%) scored the difficulty as "the same" (face validity). All participants, 30 of 30 (100%), answered positively to questions regarding the ability of the model to improve microsurgical technique (content validity). coNclusioNs Human placental arteries and bovine placental veins are convenient, anatomically relevant, and beneficial models for microneurosurgical training. Microanastomosis simulation using these models has high face, content, and construct validities. A NOMAT score of more than 5...

“…The virtual reality model for training, even if the most expensive, around 300000$ for a surgery rehearsal platform is the farthest away from the real surgery. [2,7,12,13] All of these experimental methods of training have their shortcomings. the synthetic and the virtual models are far from reaching the real feel sense one can develop only training with real vessels and also one cannot train dissecting around the aneurysm using these models.…”

Training in a specialty like cerebrovascular neurosurgery becomes more and more difficult as the access to training is limited by the increasing number of neurosurgical departments and the lack of expert centers for specific pathology. This is why an increased investment in experimental training is encountered in many centers worldwide. The best models for training the clipping technique are ex Vivo on cadaveric heads aneurysm models, animal models or augmented reality models. We present a few ex Vivo models of aneurysms mimicking ACOA, ACM bifurcation and basil are tip aneurysms using a pulsed continuous perfusion system. Clipping training on aneurysm models is an invaluable tool both for the residents and for the specialists with a special interest in cerebrovascular surgery.

“…The live rat remains to be the gold standard microsurgical training model [1,[15][16][17], it offers adjunctive practice on tissue dissection, adventitial striping, as well as enhancing 3D perception and enabling immediate vessel flow test in addition to microvascular anastomoses exercise [17]. The rising concerns of laboratory animal welfare promotes ingenious ideas into novel training model innovations.…”

Comparative use of turkey and chicken wing brachial artery models for microvascular anastomosis training

Abstract: The authors' institutional preference has shifted to the use of a turkey wing artery as the initial model for microanastomosis training. Advantages in terms of vessel size and tissue durability favor this model over the chicken wing as part of a graduated instruction process.
