Abstract:
Simulation in surgery is becoming an important component of surgical education. Training on bench top models has been demonstrated to improve technical skills. The objective of our project was to create a vascular surgery simulation model. The simulation model consists of a platform, artificial blood reservoir, artificial blood, inflow and outflow limbs, electric motor, battery, pulse generator, and cryopreserved vessel. Three different vascular surgery simulation stations were created: carotid endarterectomy with shunting and patch angioplasty, arterial bypass, and arteriovenous graft formation. A scientific study involving surgical residents will need to be undertaken to determine whether this simulator has intermodal transferability.
