摘要

背景:在掌握微神经血管吻合和动脉瘤夹闭技术之前需要广泛的训练,这是一项外科挑战。我们开发了“注入鸡翅法”,提供了一种简单而现实的训练方法,最大限度地减少了动物的使用和对动物护理和麻醉的特殊设施的需求。方法采用新鲜鸡翅作为实验材料。臂主动脉插管,140 mm Hg灌注水,解剖解剖神经血管解剖。在显微镜下进行多种显微外科训练,包括末端、侧端、外侧血管吻合和神经吻合。使用静脉贴片、夹闭、破裂和血管重建技术创建不同复杂性的动脉瘤。结果该新型训练模型成本低廉,易于获得,且不需要活体动物。所使用的动脉和静脉的直径和特征与人类的大脑相似。显微外科技术可以取得很大的进步。结论灌注式鸡翅动脉模型是一种真实的微血管训练方法。它既便宜又容易安装。这种简单性为显微外科技术的发展提供了良好的环境。

Microsurgical training on an in vitro chicken wing infusion model

Background

Microneurovascular anastomosis and aneurysm clipping require extensive training before mastering the technique and are a surgical challenge. We developed the “infused chicken wing method” to provide a simple but realistic training method minimizing animal use and need for special facilities for animal care and anesthesia.

Methods

Fresh chicken wings were used in this model. The main brachial artery was cannulated, and water was infused at 140 mm Hg followed by anatomical neurovascular dissection. Multiple microsurgical training exercises were performed under microscope vision including terminoterminal, lateroterminal, laterolateral vascular anastomosis, and nerve anastomosis. Different complexity aneurysms were created using venous patches, clipping, rupture, and vascular reconstruction techniques were performed.

Results

This novel training model is inexpensive, easily obtainable, and no live animals are required. The diameter and characteristics of arteries and veins used are similar to those of the human brain. Great microsurgical technique progress may be obtained.

Conclusions

The infused chicken wing artery model presents a realistic microvascular training method. It is inexpensive and easy to set up. Such simplicity provides the adequate environment for developing microsurgical technique.
