title: Training in endovascular surgical neuroradiology.
abstract: BACKGROUND
  During the past few years, the field of endovascular surgical neuroradiology has been expanding. Neurosurgeons, radiologists, and neurologists are currently being trained. We analyzed data from a national survey of endovascular training programs to assess the current training status and future projections.
  
  
  METHODS
  Survey participation requests were sent out to program directors and members of the Society of Endovascular Neurosurgery, the Society of Neurointerventional Surgery, and the Society of Vascular and Interventional Neurology. The format was an on-line survey designed by the authors, and completed through the SurveyMonkey.com website. Forty-three programs were identified and invited to participate.
  
  
  RESULTS
  We achieved a response rate of 81% (n = 35). Twenty-seven (79%) of the 35 respondents listed their training program as academic, and 7 (20%) listed it as a mixture of academic with private practice. The training program faculty consisted of 57 radiologists, 39 neurosurgeons, and 10 neurologists. Length of fellowship offered was the same for all specialties in 43%, and differed based on clinical experience/background in 51%. Of the programs, 86% offered a 2-year fellowship, 49% had a mandatory resident rotation, 17% offered an infolded complete fellowship for residents, and 34% offered an infolded partial fellowship. Only 9% reported no resident exposure at all. There were 12% of respondents who reported to have knowledge of vascular surgeons or cardiologists performing intracranial procedures. At the time of the survey, there were 68 fellows in training, and most entered training immediately after residency (38%), whereas 26% entered after a fellowship and another 26% trained while in residency. There will be a 14% increase of graduates within the next 5 years. Comparing the past 5 years (2003-2007) with future 5-year projections (2008-2012), the number of radiologists is declining by 37% (73 vs. 46), whereas the number of neurosurgeons (74 vs. 106) and neurologists (20 vs. 37) is increasing by 42.5% and 112%, respectively.
  
  
  CONCLUSIONS
  This survey suggests that there is a strong interest in endovascular surgical neuroradiology. The overall number of graduates is increasing, particularly in neurosurgery and neurology. Although the majority of current faculty is still comprised of neuroradiologists, the number of graduates in radiology will be decreasing during the next 5 years, reflecting a trend toward greater subspecialization within the fields of neurosurgery and neurology.
