Abstract

BACKGROUND Increasing success rates of supermicrosurgery operations have increased the importance of developing the ideal training model for super-microsurgery. Working on the model is very important for increasing and continuing microsurgery and supermicrosurgery skills. We aimed to present a standardized, simple and easy to access live training model for supermicrosurgery. METHODS The experiment was performed in the University of Health Sciences, Istanbul Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital, IDEA, Istanbul, Turkey in 2020. Twelve BALB/c male albino mice weighing 20-45 gr were used in the study. Unilateral femoral artery, vein and nerve diameters of mice were measured. Anastomosis was performed on the bilateral femoral vessels. The surgical procedure times were also recorded. RESULTS The mean weight of the mice was 36.6 ± 6.09 gr, the length was 15.10 ± 1.10 cm. The mean external diameter of the femoral artery, vein and nerves were 0.31 ± 0.34 mm, 0.48 ± 0.70 mm, 0.38 ± 0.43 mm, respectively. The mean preparation time of neurovascular structures for anastomosis was 15.75 ± 1.54 min, mean femoral artery and vein anastomosis time was 24.91±1.72 and 33.16±1.74 min, respectively. Vascular patency was detected as 100% after all vascular anastomosis procedures. CONCLUSION Mice femoral neurovascular structures are similar to rats in terms of basic morphology, and they are small enough for super-microsurgery education model. Dissection of mice femoral bundles are easy to perform. In terms of training models, anesthetic requirement and laboratory costs are less for mice, and handling them is much easier compared to rats; thus, making them especially suitable for basic supermicrosurgery training courses.
一种新型的活体超显微手术基础训练实验室模型:小鼠股动脉、静脉和神经
背景:随着超显微外科手术成功率的提高,建立理想的超显微外科手术训练模式显得尤为重要。研究这个模型对于提高和延续显微外科和超显微外科技术是非常重要的。我们的目标是提供一个标准化、简单、易于访问的超显微外科现场训练模型。方法实验于2020年在土耳其伊斯坦布尔健康科学大学Mehmet Akif Ersoy胸心血管外科培训与研究医院进行。实验选用体重20 ~ 45 g的BALB/c雄性白化小鼠12只。测量小鼠单侧股动脉、静脉、神经直径。对双侧股血管进行吻合。同时记录手术时间。结果小鼠平均体重36.6±6.09克,体长15.10±1.10 cm。股动脉、股静脉、股神经平均外径分别为0.31±0.34 mm、0.48±0.70 mm、0.38±0.43 mm。吻合神经血管结构的平均准备时间为15.75±1.54 min,平均股动脉和股静脉吻合时间分别为24.91±1.72 min和33.16±1.74 min。所有血管吻合术后血管通畅率均为100%。结论小鼠股神经血管结构基本形态与大鼠相似,且足够小,可作为超显微外科教育模型。小鼠股束的解剖很容易进行。在训练模型方面,小鼠的麻醉需求和实验室成本较低,处理起来也比大鼠容易得多;因此,它们特别适用于基础的超显微外科培训课程。
