A Study of Human Placenta as a Model for Microsurgical Aneurysm Clipping


About this study

The purpose of this study is to obtain human placentas from obstetric patients giving birth at Mayo Clinic. We then plan to produce model aneurysms within the placentas using a validated methodology. Model placentas will then be used for training purposes in a microsurgical lab available to all neurosurgical residents.
