Vascular Neurology Fellowship Training
Vascular neurology fellowship training is a structured, accredited subspecialty program that prepares neurologists to diagnose and manage stroke, transient ischemic attack (TIA), cerebrovascular malformations, and related conditions. This page covers the program structure, accreditation standards, clinical scenarios addressed by the training, and the boundaries that distinguish vascular neurology from adjacent subspecialties. The fellowship represents the primary credentialing pathway for neurologists who intend to practice in dedicated stroke units or comprehensive stroke centers.
Definition and scope
Vascular neurology is the subspecialty of neurology focused on diseases of cerebral blood vessels and their neurological consequences. Fellowship training in this domain is formally accredited by the Accreditation Council for Graduate Medical Education (ACGME), which publishes program requirements specific to vascular neurology under its neurology program requirements framework (ACGME Program Requirements for Graduate Medical Education in Vascular Neurology).
ACGME-accredited vascular neurology fellowships run for 12 months following completion of a neurology residency, which itself is a 4-year program after medical school. The clinical scope encompasses acute ischemic stroke, hemorrhagic stroke (intracerebral and subarachnoid), cerebral venous thrombosis, carotid and vertebral artery disease, and intracranial atherosclerosis. Fellows also develop competency in brain imaging interpretation, neurosonology (transcranial Doppler and carotid duplex ultrasound), and evidence-based secondary prevention protocols.
Physicians completing this training are eligible to pursue subspecialty board certification through the United Neuroscience Alliance or, more commonly, through the American Board of Psychiatry and Neurology (ABPN), which administers the vascular neurology subspecialty examination. The ABPN defines the certification as requiring 12 months of ACGME-accredited fellowship training, a valid primary neurology certification, and passage of the written subspecialty examination.
The broader regulatory and credentialing landscape for neurological subspecialties is described in the regulatory context for neurological specialty practice.
How it works
The fellowship follows a competency-based structure organized around the ACGME's six core competencies: Patient Care, Medical Knowledge, Practice-Based Learning and Improvement, Interpersonal and Communication Skills, Professionalism, and Systems-Based Practice. Stroke programs accredited by The Joint Commission as Comprehensive Stroke Centers (Joint Commission Comprehensive Stroke Center Certification) commonly serve as the host institutions for ACGME-accredited fellowships, ensuring fellows train in high-volume, protocol-driven environments.
A standard 12-month vascular neurology fellowship is structured across the following phases:
- Acute stroke unit rotation — Direct management of hyperacute presentations, including administration of intravenous thrombolysis (IV alteplase) within the 4.5-hour window established by clinical trials and endorsed by the American Heart Association/American Stroke Association (AHA/ASA Stroke Guidelines).
- Neurovascular imaging interpretation — Systematic training in CT perfusion, MRI diffusion-weighted imaging (DWI), MR angiography (MRA), CT angiography (CTA), and catheter angiography review.
- Neurosonology training — Hands-on competency in transcranial Doppler ultrasonography and extracranial duplex imaging, with many programs requiring completion of standardized case logs.
- Neurointensive care — Rotations in neurocritical care units where fellows manage elevated intracranial pressure, hemorrhagic transformation, cerebral edema, and vasospasm following subarachnoid hemorrhage.
- Outpatient stroke prevention clinic — Longitudinal management of patients with TIA or minor stroke, including anticoagulation management, risk factor optimization, and coordination with vascular surgery.
- Research and quality improvement — Participation in stroke registry data collection (e.g., the AHA's Get With The Guidelines–Stroke program) and at least one scholarly project.
Fellows are evaluated through direct observation, case-based assessments, and milestone reporting submitted semi-annually to the ACGME via the Milestone Project framework.
Common scenarios
Vascular neurology fellows encounter a defined set of high-acuity clinical presentations that recur throughout training and structure clinical decision-making:
- Wake-up stroke — Patient presents with neurological deficits on awakening with an unknown time of onset; fellows apply advanced imaging selection criteria (DWI-FLAIR mismatch on MRI) to determine thrombolysis eligibility.
- Large vessel occlusion (LVO) — Middle cerebral artery or basilar artery occlusion requiring rapid triage for mechanical thrombectomy; fellows coordinate with neurointerventional teams within the extended window up to 24 hours in selected patients (AHA/ASA Thrombectomy Guidelines).
- TIA with high ABCD2 score — Rapid outpatient or inpatient evaluation pathway for patients with transient symptoms and elevated short-term recurrence risk; fellows implement dual antiplatelet therapy protocols and vascular imaging within 24 hours.
- Intracerebral hemorrhage (ICH) — Management of hematoma expansion, blood pressure targets, and reversal of anticoagulation in patients on warfarin or direct oral anticoagulants.
- Cerebral venous sinus thrombosis (CVST) — A less common but diagnostically challenging condition; fellows develop proficiency in recognizing CVST on MRV and initiating anticoagulation even in the presence of hemorrhagic infarction.
The stroke types, causes, and warning signs reference provides foundational context for the clinical categories that define most of the fellow's caseload.
Decision boundaries
Vascular neurology training has specific boundaries that distinguish it from two related subspecialties: neurointerventional surgery and neurocritical care.
| Domain | Vascular Neurology Fellow | Neurointerventional Fellow | Neurocritical Care Fellow |
|---|---|---|---|
| IV thrombolysis decision | Primary operator | Supportive role | Shared |
| Mechanical thrombectomy | Refers/coordinates | Primary operator | Monitoring role |
| ICP management | Participates | Rarely involved | Primary operator |
| Carotid stenting decision | Evaluates, refers | May perform | Rarely involved |
| Secondary prevention clinic | Primary operator | Rarely involved | Rarely involved |
Vascular neurology fellows do not perform catheter-based interventional procedures (angioplasty, stenting, coil embolization). That scope belongs to neurointerventional radiology or endovascular neurosurgery fellowships. Similarly, while fellows rotate through neurointensive care, primary management of multiday neurocritical care admissions falls within the scope of neurocritical care fellowship training.
The ACGME distinguishes these boundaries in separate program requirement documents for each subspecialty. Physicians seeking comprehensive information on the full neurology subspecialties landscape will find formal classifications across all recognized training tracks.
