Carotid Endarterectomy Surgical Simulation Model Using a Bovine Placenta Vessel.

摘要: Background Carotid endarterectomy (CEA) is a common, well-developed surgical procedure. Although simulation gaining in importance for residency training, CEA practice opportunities residents are limited. Objective To describe new haptic model. Methods Six bovine placentas were used to create the Each placenta provided about 6 large arterial and venous bifurcations. In total, 36 large-vessel bifurcations dissected prepared simulation. Bovine vessels arranged simulate common carotid artery (CCA), internal (ICA), external (ECA). The diameters wall thicknesses measured compared with human CCA, ICA, ECA parameters. Results All suitable modeling training. Mean ± SD of simulated CCAs, ECAs, ICAs 11.2 1.8, 4.3 0.5, 9.8 3.0 mm, respectively, from nondilated veins 8.7 1.4, 4.4 1.3, 7.2 1.7 arteries. vessel 2.0 0.6 mm arteries 1.4 0.5 veins. Placental tissue had dimensions handling characteristics similar those procedure its subtasks, including vessel-tissue preparation skills performance, could be reproduced high fidelity. Conclusion A training model inexpensive readily available closely resembles can provide convenient valuable addition vascular surgery
