Microvascular anastomosis training model based on a Turkey neck with perfused arteries.

摘要: OBJECTIVE The microvascular anastomosis (MA) technique remains an important aspect of modern neurosurgical practice. Specialized training is essential for mastering the small vessels. To minimize animal use and to create a simple but realistic model, we developed pulsatile perfused arteries model based on turkey carotid training. METHODS Approximately 10-cm-long segments necks were used as material set up this model. diameter at neck level was found be between 1 3 mm. Both segment cannulated incorporated into closed circulation circuit consisting silicone tubes infusion pump that provided continuous arterial-like flow pulsation during MA Tubing connection with both proximal distal ends allowed circulatory patency vessel clamping creation. Different fluids ranging from water various colored solutions or even whole blood could vascular perfusion in experimental setup. Fluid output maintained 11 16 ml/min. Minimum pressure 80 cm/H20, maximum 160 cm/H20. Mean fluid through 8 13 End-to-end, end-to-side, side-to-side may performed RESULTS This provides several advantages: materials are easily obtainable inexpensive, realistic, easy manage, there no need special facilities care anesthesia required live animals. structure essentially identical human cortical vessels branches superficial temporal artery. CONCLUSION presents It inexpensive setup educational purposes. can needs Wide enhance popularize education.
