Vascular Neurology and Stroke Neurointervention fellowship training program

Early Specialization in Stroke Neurointervention / Interventional Stroke Pathway (ESNI)

SUNY Upstate Medical University Hospital is proud to offer a training pathway tailored for Neurology residency applicants interested in pursuing a career in Vascular Neurology and Stroke Neurointervention.

The residency program pathway is structured to provide additional subspecialty training in all aspects of Stroke management including the delivery of intravenous tPA and endovascular treatment of ischemic cerebrovascular disease. Through dedicated rotations managing patients on the Stroke and NeuroICU services while also covering the Neuroangiography suite, residents will gain the necessary clinical experience and training in all technical aspects necessary for proficiency in diagnostic cerebral angiography and endovascular treatment of stroke (obtaining procedural skills over the course of the PGY3 and PGY4 years of residency training).

The resident will work with faculty in the departments of Neurology, Neurosurgery and Radiology. For interested trainees there are additional opportunities for experience in the performance and interpretation of Neurovascular ultrasound studies. ESNI residents will have preferred selection over external candidates for the ACGME Vascular Neurology fellowship program.

After successful completion of the residency program, ESNI candidates will have preferred selection for an internal fellowship position in the combined Vascular Neurology fellowship training program at Upstate University Hospital Comprehensive Stroke Center.

A post residency combined 2-year Vascular Neurology and Stroke Neurointervention fellowship training program will be available to eligible residents (without VISA restrictions). The fellow may serve as Clinical Instructor in the second year, with opportunities to practice as attending Stroke and Telestroke service lines. The combined program allows clinical fellows in the ACGME accredited Vascular Neurology program to extend training with a non-ACGME year and gain additional experience for proficiency in dignostic cerberal angiography and interventional stroke procedures.

Graduates of our combined fellowship program are board eligible for the ABPN Vascular Neurology Board certification exam and may choose to go on to practice Stroke Neurointerventions at a Level-2 / thrombectomy-capable stroke center (TSC) or pursue additional training in Interventional Neurology.

The goal of this training pathway is to establish a clear route for Neurology residents to obtain expertise in the comprehensive care of stroke patients, to include the delivery of both medical (IV thrombolysis, secondary prevention, diagnosis and prevention, neurorehabilitation) and endovascular therapies of acute ischemic stroke (e.g intra-arterial thrombolysis/spasmolysis, angioplasty and stenting, mechanical thrombectomy)

"The ability to visualize and treat various cerebrovascular pathologies drew my clinical interests towards interventional neurology. Upstate's ESNI pathway is unique in that it allows for early exposure to interventional neurology that would not otherwise be available to many neurology residents. It provides multi-disciplinary training with clinicians from different fields. The Neuro IR staff are always welcoming and willing to teach. The early exposure to neurointerventional cases will help with gaining much needed experience for future fellowships."

"The ESNI track at Upstate interested me as it provides a unique opportunity to be very much involved with and learn about acute stroke intervention early on in residency. Residents in the ESNI track work alongside and learn approaches and techniques from experienced neurointerventionalists from three different disciplines. In addition to attendings, the IR staff is friendly, knowledgeable, and frequently teach inside and outside the angio suite. The ESNI track is also a great opportunity to confirm fellowship interest."

Frequently Asked Questions

Expand all

What is ESNI?

Early Specialization in Stroke NeuroIntervention (ESNI) is a training option for adult neurology resident applicants who identify an early desire to specialize in Vascular Neurology and Stroke Neurointervention. ESNI training includes a total of 16 weeks of dedicated Neurointerventional service rotations over the course of the PGY3 and PGY4 years of Neurology residency training. Trainees will participate in the continuum of acute stroke management bridging patient care from initial diagnosis and management, through IV thrombolysis, to the Neuroangiography suite while serving as Stroke Sr., with additional exposure to the tenets of neurocritical care on the NeuroICU service.

The ESNI pathway provides early training in Neurointervention built into the residency program, strengthening the application of Neurology trainees planning on advanced fellowship training in Interventional Neurology/Endovascular Surgical Neuroradiology/Interventional Neuroradiology after completion of the residency program.

What is the combined fellowship?

The Upstate combined Vascular Neurology and Stroke Neurointervention post residency fellowship comprises 1 year of ACGME-accredited vascular neurology with 1 year of non-ACGME training in Stroke Neurointervention.  The second year of fellowship includes opportunities to serve as faculty, participating in Telestroke and the inpatient Stroke service, providing our trainees with comprehensive experience and confidence in the management of all aspects of cerebrovascular disease by the end of the 2-year fellowship. Fellows will participate in stroke neurointerventions and log cases across both years of training. For foreign medical graduates with visa restrictions, at the moment Upstate is unable to sponsor J-1 for the (non-ACGME) second year (please contact for updates).


What proceduress are included in Stroke Neurointervention / Interventional Stroke?

Digitally subtracted catheter cerebral angiography, mechanical thrombectomy (including use of stent-retrievers, aspiration devices), microcatheterization of cerebral vessels, intra-arterial administration of spasmolytics, percutaneous intra and extracranial balloon-angioplasty and stenting, transradial and alternative access. Trainees will also gain experience in the interpretation of neuroimaging related to cerebrovascular disease including, but not limited to, CT/MR angiography of the head and neck, CT perfusion imaging of the brain, and Carotid/Transcranial ultrasound.

What are the procedural requirements for completion of the fellowship program?

Successful completion of the program requires demonstrated understanding of the basic indications for catheter angiography and stroke intervention, technical mastery of biplanar fluoroscopy equipment including basic catheter and wire manipulation in the cerebrovascular system and rapid interpretation of angiographic images, familiarity with the use of all current FDA approved thrombectomy devices in acute ischemic stroke, recognition and management of intraprocedural and postprocedural complications, and basics of post procedural management in a neurocritical care setting. Candidates are expected to maintain a case log of all diagnostic and neurointerventional procedures during their training; to regularly participate in neuroscience conferences and morbidity/mortality conference with an emphasis on quality improvement and resident education. Candidates are strongly encouraged to produce original manuscripts for presentation and/or publication in the field of stroke and neurointervention. If so desired, fellows may extend their training to increase their case volume experience. Trainees will adhere to performance standards set during the ACGME year.

How are candidates selected for the ESNI pathway?

Applicants to the Neurology residency training program may express interest internally early in their intern year (PGY1/PGY2). The deadline for consideration is Spring (April/May) of the PGY2 training year. Interested residents undergo interviews with the Program Director, lead Neuro-IR technologist and Attending Neurointerventional staff prior to selection. The ESNI pathway begins at the start of the PGY3 academic year (July 1st) of the adult Neurology residency program. After graduation there are 1-2 Vascular Neurology fellowship positions available for PGY5/6 year of training.

What is the orientation process?

Selected residents undergo mandatory radiation safety and conscious sedation management training prior to starting the PGY3 year. Trainees must maintain yearly NIHSS certification and complete ENLS (emergency neurologic life support) training (certification is valid for 2 years). Trainees are oriented to the Neuroangiography suites and equipment by the Neuro-IR technologist and/or Neurointerventional attending.
