Human placenta aneurysm model for training neurosurgeons in vascular microsurgery.

Background: Neurosurgery, a demanding specialty, involves many microsurgical procedures that require complex skills, including open surgical treatment of intracranial aneurysms. Simulation or practice models may be useful for acquiring these skills before trainees perform surgery on human patients.

Objective: To describe a human placenta model for the creation and clipping of aneurysms.
