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

ESNI Neurosuite image

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 thrombolysis 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 necessary for proficiency in diagnostic cerebral angiography and exposure to the endovascular treatment of stroke (obtaining procedural skills over the course of the PGY-3 and PGY-4 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 in the performance and interpretation of Neurovascular ultrasound studies.

After successful completion of the residency program, SNI 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 1-2 year Vascular Neurology and Stroke Neurointervention fellowship training program is available to eligible residents (no VISA sponsorship is currently available for the second year (non-ACGME)). The fellow may serve as Clinical Instructor in the second year, with opportunities to participate in the attending Stroke and Telestroke service line. The combined 2-year program allows clinical fellows in the ACGME accredited Vascular Neurology program to extend training with a non-ACGME year to gain additional experience for proficiency in diagnostic cerebral 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 for acute ischemic stroke (e.g intra-arterial thrombolysis/spasmolysis, angioplasty and stenting, mechanical thrombectomy).

The pathway also affords interested Neurology residents early exposure and hands-on training in the technical aspects of diagnostic cerebral angiography and neurointervention, embedded in their residency training, and serves as a platform for trainees pursuing Interventional Neurology fellowship training post graduation.

"Evaluation and treatment of stroke are assessed by a neurologist which makes exposure to interventional procedures crucial for educating neurologists. Starting with the PGY-1 year, residents are trained by credentialed physicians who structured the stroke Neurointervention track to encourage cognitive knowledge of pathophysiologic vascular processes. Residents receive clinical experience on the Neuro ICU and Stroke services. There is hands-on experiences in the angiography suite, and exposure to the techniques used in day-to-day practice which is a golden opportunity. As a member of the SNI track, I am gaining procedural skills, a stronger understanding of vascular neurology, and the ability to recognize and prevent complications in a standardized curriculum. I feel this will make me a skilled neurologist and a strong applicant for fellowship."

"The ESNI program gives me the opportunity to see and treat the entire range of stroke patients in all phases of stroke care. As a neurology resident at a comprehensive stroke center I get training in code, consult, neuro ICU, floor, and outpatient medical management of stroke patients. As an ESNI resident I get to go into the angio-suite and get training in diagnostic and interventional angiography required for procedural management of stroke patients. At the end of my training, I want the entire toolkit, and ESNI gives me the path to build it."

"The ESNI pathway is a great opportunity for residents to learn the intricacies of cerebrovascular anatomy in the angiography suite. The program not only allows us to become comfortable with all aspects of stroke care, right from acute interventions to workup and secondary prevention followed by rehabilitation, but also enables us to go a step further by developing procedural skills in cerebral angiograms and neurosonology. I am fortunate to get this opportunity early on in my training, and am confident that this experience will help me immensely when I apply for fellowship and in my career after that as well."

"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."

"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 training at Upstate is an incredible pathway to learn the procedures such as Mechanical thrombectomy, DSA, Spasmolysis and Aneurysm coiling etc. As a Neurology resident, I find ESNI track very helpful in learning from attendings of different specialties. This exposure in the beginning of residency would be instrumental in deciding the fellowship interests and research prospects in this rapidly evolving field of Neuro-intervention."

Frequently Asked Questions

What is SNI?

Specialization in Stroke NeuroIntervention (SNI) is a training option for adult neurology resident applicants who identify an early desire to specialize in Vascular Neurology and Stroke Neurointervention. SNI 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 SNI 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).
