Training in Cerebral Aneurysm Clipping Using Self-Made 3-Dimensional Models

摘要: Introduction Recently, there have been increasingly fewer opportunities for junior surgeons to receive on-the-job training. Therefore, we created custom-built three-dimensional (3D) surgical simulators training in connection with cerebral aneurysm clipping. Methods Three patient-specific models were composed of a trimmed skull, retractable brain, and hollow elastic its parent artery. The brain using 3D printers via casting technique. artery made by printing lost-wax Four residents 2 neurosurgeons attended the courses. trainees retracted observed arteries aneurysmal neck, selected clip(s), clipped neck an aneurysm. duration simulation was recorded. A senior neurosurgeon then assessed trainee's technical skill explained how improve his/her performance procedure video actual surgery. Subsequently, trainee attempted clipping again, same model. After course, each skill. critiqued usefulness model effectiveness course. Results Trainees succeeded performing line Their skills tended upon completion Conclusion These are easy create, believe that they very useful techniques needed
