Neuroendovascular Program

Post-Residency Neuroendovascular Fellowship

The University at Buffalo Neurosurgery endovascular surgical neuroradiology program is internationally recognized for innovation in minimally invasive treatments for neurological disorders. In collaboration with a multi-disciplinary team of scientists at the acclaimed Canon Stroke & Vascular Research Center, the endovascular faculty and fellows conduct “translational” research, which involves the rapid application of laboratory discoveries to the clinical arena. Additionally, the faculty and fellows participate in numerous clinical trials, thus staying abreast of the latest advances in technology.

The patient base is broad and diversified, giving fellows the opportunity to treat a broad array of pathology using endovascular techniques. Specific areas of training include:

  • Intracranial angioplasty
  • Brachiocephalic angioplasty
  • Carotid stent
  • Intracranial stent
  • Embolization of arteriovenous malformation
  • Aneurysm endovascular occlusion
  • Embolization of tumor, extracranial and intracranial
  • Test occlusion / occlusion of cranial vessel
  • Embolization / carotid cavernous fistula (head, neck, spine)
  • Spinal angiography, diagnostic
  • Spinal embolization
  • Intracranial stent
  • Thrombolysis, intraarterial, acute stroke or vessel occlusion
  • Diagnostic angiography

The program is designed to ensure that fellows are comprehensively trained in all areas of endovascular surgical neuroradiology.


The endovascular fellowship is open to applicants who have completed an ACGME-accredited residency training program in either neurosurgery or neuroradiology.

All candidates for fellowship must have completed at least 12 months (preferably consecutive) of neuroradiology training. In addition, all endovascular surgical neuroradiology fellowship candidates must be skilled in catheter-based techniques.

Candidates with a neurosurgery background must have fulfilled the following preparatory requirements, in addition to the common requirements cited above:

  1. Completion of an ACGME-accredited residency program in neurological surgery
  2. Completion of a course in basic radiology skills

The basic radiology skills and neuroradiology training may be acquired as an elective at some point during the neurological surgery residency. Alternatively, the applicant can fulfill these requirements during the first year of fellowship training at UBNS.

Candidates with a radiology background must have fulfilled the following preparatory requirements, in addition to the common requirements cited above:

  1. Completion of an ACGME-accredited residency in diagnostic radiology
  2. Completion of three (3) months of clinical experience in an ACGME-accredited neurological surgery program

The clinical requirement may be acquired as an elective during diagnostic radiology and/or neuroradiology training.

Application Process

Applications for the endovascular surgical neuroradiology fellowship are accepted on an ongoing basis. Candidates are required to send the following:

  1. Updated CV
  2. Cover letter describing career goals and anticipated start / end dates for fellowship training
  3. Three (3) letters of recommendation
  4. Any Visa requirements

The above documents should be forwarded to:

Adnan Siddiqui, MD, PhD

Candidate packets will be reviewed no less than monthly by the endovascular faculty members: Elad Levy, MD, Adnan Siddiqui, MD, Kenneth Snyder, MD, and Jason Davies, MD. Once the faculty has made their decision, candidates will be notified of possible interview dates. Upon acceptance into the program, the candidate will receive an offer letter confirming dates of fellowship. Candidates are requested to sign and return a confirmation of receipt and an acceptance of the offer.

Subsequent correspondence to the candidate will entail all documents regarding hospital credentialing, licensure, university appointment, and human resource matters.
