Abstract
Reduced number of working hours for residents and the trend toward minimal or even noninvasive treatment of cerebral aneurysms have resulted in residents’ decreased exposure to live surgery in the operating room. This decrease becomes increasingly relevant when surgeons encounter complications, especially vascular injuries and intraoperative rupture of aneurysms, after completion of their training, neurosurgery residents will face complicated cases and intraoperative aneurysmal rupture in their practice while they are on their own, and to develop competency in managing cerebral aneurysms, laboratory training will be the compensation mechanism to cover the decreased hands-on experience in the OR. In this chapter we will describe a more realistic aneurysm model, which allows repetitive training under lifelike conditions for residents and other trainees to practice surgical clipping of cerebral aneurysms.
Artificial aneurysms were created in the usual locations of the cerebral vasculature of human cadaveric head specimens to train residents and neurosurgeons in the practice of surgical clipping of cerebral aneurysms and the management of complications associated with intraoperative aneurysmal rupture. Specimens were specially prepared for this technique and connected to a pump that blood simulant into the vessels. This setting created a situation in the cadaver which simulated live surgery in terms of bleeding, pulsation, and softness of tissue.
Neurosurgical residents were able to practice aneurysmal clipping and management of intraoperative rupture in a lifelike surgical environment and at the same human anatomy.
