Registration Form-2016

Call for abstracts 2016

OrricoThis year’s annual Spring MNNS business meeting was held at the Bank Restaurant boardroom in Minneapolis on Friday evening, April 15th. The organization’s finances were reviewed along with anticipated expenses for the fall 2016 academic meeting to be held at the St. Paul Hotel from October 7-9th. The Society remains a stable financial concern although the need for increased member and industry participation to help support this program was emphasized. The most recent Counsel of State Neurosurgical Society’s (CSNS) resolutions were also discussed, most notably Resolution III-2016S: On-Call Compensation Analysis and Resolution VI-2016S: Impact of policy changes regarding simultaneous neurosurgical procedures.

The remainder of the program was primarily a wide ranging conversation with the Society’s guest speaker, Ms. Katie Orrico, the Director of the AANS’ Washington Office who provided her usual candid insights into the anticipated policy changes likely to affect the practice of neurosurgery over the next several years.


A polite reminder to go to 2016 Minnesota Neurosurgical Society Dues Online and pay your dues for the 2016 year.   Alternatively, dues may also be paid in person at the Business Meeting or by check to:

After internship in New Hampshire, three years of military service and one year of general surgery residency, his neurosurgical residency was completed at Mayo Clinic.  He remained in the Mayo Clinic Neurosurgery Department thereafter, being named Professor in 1988 and serving as Chair of Neurosurgery from 1992-2004. Dr. Piepgras was president of the AANS Joint Section of Cerebrovascular Diseases from 1990-1991. He held the position as President of the American Academy of Neurological Surgery from 2002-2003 and the Society of Neurological Surgeons (“Senior Society”) from 2003-2004. He served on the RRC for Neurological Surgery and the American Board of Neurological Surgery, including Chair from 2002-2003.  Dr. Piepgras’ research and clinical interests include the surgical treatment and epidemiology of occlusive cerebrovascular disease and the management of arteriovenous malformations and intracranial aneurysms.  He has extensively studied the natural history of unruptured intracranial aneurysms, including being Co-investigator on the sentinel study funded by the NINDS. David has published over 200 peer-reviewed journal articles, multiple book chapters and has served as a reviewer for Neurosurgery, Stroke and The New England Journal of Medicine. He has been an invited speaker and held many visiting professorships all over the world. He remains clinically active in The Mayo Clinic Neurosurgery Program.
