DESARROLLO DE TÉCNICAS MICROQUIRÚRGICAS USANDO TINCIÓN Y PRESERVACIÓN VASCULAR EN PLACENTA HUMANA CON MODELOS CRANEALES 3D

Microcirugía 3D

Abstract

With the increase in restrictions on hours and exposure of medical residents to certain surgical procedures, the need to acquire skills outside the operating room through simulation has been raised. The aim of this work is to demonstrate that the use of human placentas with a three-dimensional (3D) cranial model is a high fidelity method for the development of microsurgical techniques. A technical evaluation study was carried out in the Dr. Evandro de Oliveira Microsurgery Laboratory of the Hospital de la Beneficiencia de Portugal in São Paulo, using 15 placentas with coloration techniques and vascular preservation with silicone for molds; performing vascular anastomosis, arachnoid and Silvian valley dissection, in addition to simulating tumor resection. Qualitatively, the human placenta is a high fidelity and universal access method for the acquisition of microsurgical skills, which, associated with a 3D cranial model, allows the refinement of the craniotomies, hand-eye coordination, proprioception, and depth relationship required for neurosurgical approaches.
