title: An efficient microvascular anastomosis training model based on chicken wings and simple instruments.
abstract: OBJECTIVE
  The aim of this study is to introduce a microvascular training model based on use of materials that can be easily obtained from the daily surroundings.
  
  
  METHODS
  Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.
  
  
  RESULTS
  The instruments used for setting up this model were simple and easy to use; therefore, the time required for preparation of the materials and dissection of the chicken wings was only approximately five to ten minutes. The characteristics of 20 chicken wings were analyzed. The length of the brachial artery to the radial artery was 8 - 10 cm. The average diameter of the brachial artery was 1.3 mm ± 0.2 mm and that of the radial artery was 1.0 mm ± 0.2 mm. Taking advantage of these characteristics, the proximal brachial artery was grafted to the radial artery for practice of end-to-side anastomosis.
  
  
  CONCLUSIONS
  This study suggests an effective and feasible method for microvascular anastomosis training using chicken wing arteries and simple microinstruments. This model may simulate the conditions of a superficial temporal artery to middle cerebral artery anastomosis surgery.
