背景：超显微外科是重建外科中越来越重要的技术。与标准显微外科手术相比，它需要更精确的技术技能。目前所有可用的生物训练模型都涉及使用活体大鼠。一个非生命的模型将更容易获得和成本效益的做法。我们已经开发了这样一个模型，使用从当地杂货店购买的鸡大腿。方法：坐骨神经血管束被确定在20只鸡大腿和解剖远端的标本的结束。在沿着动脉、静脉及其各自分支的几个点处测量血管直径。然后将直径在0.3-0.8 mm范围内的血管分开，并尝试进行超显微外科手术。坐骨动脉和静脉的分支模式在解剖学上与中间和末端的二级和三级分支一致，范围在0.3-0.8 mm之间。在所有标本中，至少可以识别出一条0.3 mm的血管，尽管有时需要额外的肌内解剖。结果表明，supermicrosurgical alcohoses可以成功地进行使用这些branchs.Conclusions：本研究介绍了一种新的，方便，经济的模式，利用容易获得的鸡大腿supermicrosurgery。鸡大腿具有解剖学上一致的血管分支模式，并且可以容易地识别和分离用于训练的适当尺寸的血管。希望发展或改进超微外科技能的外科医生可能会发现这种无生命的生物模型非常有用。由爱思唯尔有限公司代表英国整形、重建和美容外科医生协会发布。
Background: Supermicrosurgery is an increasingly important technique in reconstructive surgery. It requires a more technically refined skill set compared with standard microsurgery. All currently available biologic training models involve the use of live rats. A nonliving model would be more accessible and cost-effective for practice. We have developed such a model using chicken thighs purchased from a local grocery store.Methods: The ischiatic neurovascular bundle was identified in 20 chicken thighs and dissected distally to the end of the specimen. The vessel diameters were measured at several points along the artery, vein, and their respective branches. Vessels with diameters in the 0.3-0.8-mm range were then divided and supermicrosurgical anastomoses were attempted.Results: The branching pattern of the ischiatic artery and vein were anatomically consistent with intermediate and terminal secondary and tertiary branches consistently in the range of 0.3-0.8 mm. In all specimens, at least one 0.3-mm vessel could be identified, though additional intramuscular dissection was sometimes required. It was demonstrated that supermicrosurgical anastomoses could be successfully performed using these branches.Conclusions: This study introduces a novel, convenient, and economical model for supermicrosurgery utilizing easily obtained chicken thighs. The chicken thighs have an anatomically consistent vascular branching pattern, and vessels of appropriate sizes for training can be easily identified and isolated. Surgeons looking to develop or refine supermicrosurgical skills may find this nonliving, biologic model very useful.
