OBJECT Endovascular interventions have become an essential part of a neurosurgeon’s practice. Whether endovascular procedures have been effectively integrated into residency curricula, however, remains uncertain. The purpose of this study was to assess the preparedness of US neurosurgery graduate trainees for neuroendovascular fellowship. METHODS A multidomain, global assessment survey was sent to all directors/faculty of neuroendovascular fellowship programs involved in training of US neurosurgery graduates. Surveyees were asked to assess trainees as they entered fellowship. RESULTS The response rate was 78% (25/32). Of respondent program directors, 38% reported that new fellows did not know the history and imaging of the patient and 50% were unable to formulate an appropriate treatment plan. As many as 79% of fellows were unfamiliar with endovascular devices and 75% were unfamiliar with angiographic equipment. Furthermore, 58% of fellows were unable to perform femoral access, 54% were unable to perform femoral closure, 79% were unable to catheterize a major vessel, 86% were unable to perform a 4-vessel angiogram, and 100% were unable to catheterize an aneurysm. Additionally, program directors reported that over 50% of fellows could not recognize neurovascular anatomy and 54% could not recognize/classify vascular abnormalities. There was an overall agreement that fellows demonstrated professionalism and interest in research and had good communication/clinical skills. CONCLUSIONS The results of this study suggest potential gaps in the training of neurosurgery residents with regard to endovascular neurosurgery. In an era of minimally invasive therapies, changes in residency curricula may be needed to keep pace with the ever-changing field of neurosurgery.
