The rat femoral artery (RFA) anastomosis model has been the gold standard in microsurgical simulation training. While effective, live animal use requires animal use committee regulation and costly maintenance. Our institution's animal laboratory is remote to the hospital, limiting access by our busy surgical residents with their limited duty hours. We present an alternative convenient, cost-effective model. Ten frozen turkey wings were divided into distal and proximal segments. Vessel diameter, length, and anastomosis perfusion were assessed. Proximal brachial arteries ("humeral" segments) measured 8.85 ± 1.14 cm long with diameter 1.69 ± 0.27 mm. Distal brachial arteries ("forearm") measured 10.5 ± 2.06 cm long with diameter 1.25 ± 0.25 mm. An 8-lb box (~20 wings) cost $13.76. Separate use of the segments provides two training sessions with $0.35 per session effective cost. Our average cost for RFA microsurgical training sessions was $120 dollars for a single rat 2-hour session and $66 per rat if a maximum crate load of six rats was used. Besides significant cost, not all training programs are equipped to house, care for, and use rats in microsurgical training. We now use turkey wings for microvascular training. They are cheap, abundant, readily accessible for training, and consistent with tissue quality and vessel size approximating human systems.
大鼠股动脉（RFA）吻合模型一直是显微外科模拟训练的金标准。虽然有效，但活体动物的使用需要动物使用委员会的监管和昂贵的维护。我们机构的动物实验室远离医院，限制了我们忙碌的外科住院医师在有限的工作时间内使用。我们提出了一种替代的、方便且具有成本效益的模型。十个冷冻火鸡翅膀被分为远端和近端部分。评估了血管直径、长度和吻合灌注。近端肱动脉（“肱骨”段）长 8.85±1.14cm，直径 1.69±0.27mm。远端肱动脉（“前臂”）长 10.5±2.06cm，直径 1.25±0.25mm。一个 8 磅的盒子（~20 个翅膀）的价格为 13.76 美元。单独使用这些段可以进行两次训练，每次训练的有效成本为 0.35 美元。我们的 RFA 显微外科训练课程的平均成本为每只大鼠 2 小时的单次课程 120 美元，如果使用最大的 6 只大鼠笼，则每只大鼠的成本为 66 美元。除了显著的成本外，并非所有的培训计划都具备在显微外科培训中饲养、照顾和使用大鼠的能力。我们现在使用火鸡翅膀进行微血管训练。它们便宜、丰富、易于获得，并且与组织质量和血管大小与人体系统相近。
