Vascular Neurology Fellowship

About the Program

The current ACGME-approved Vascular Neurology Fellowship Program builds on the rich tradition of training stroke fellows at the University of Iowa and capitalize the institutional excellent clinical, training and research resources. We are committed to training outstanding physicians in vascular Neurology.

University of Iowa is one of the 25 RCCs nationally part of the NIH-StrokeNet network.

The Group at the University of Iowa is involved in many intra and extramural research projects. Research and scholar activities are highly encouraged. Fellows will have the opportunity to be mentored in their research enterprises.

Vascular Neurology Fellowship Training

The vascular neurology fellowship alternates inpatient rotations with outpatient care and electives.

Inpatient Stroke Service

The core rotation is the inpatient stroke service. The fellow attends the service an average of 4-5 months a year. During that time, the stroke fellow serves as a link between the stroke attending and the senior and Junior neurology residents. Patients are admitted to the dedicated stroke unit, as well as in the surgical and neuroscience intensive care unit (SNICU). Rather than a hands-on patient experience, the fellow’s role is to supervise the work of the neurology residents. The stroke attending gives gradual autonomy to the fellow, which includes leading stroke round and code stroke activations. The goal is to prepare the fellow for successfully managing an academic or private practice stroke service.

There are two main stroke services. Stroke 1 = manages the inpatient strokes. Stroke 2 = manages consults, inpatient code strokes and daily ER admissions as well as outpatient transfers. Each stroke service is staffed with an attending an several neurology residents. This system decongests the services and allows time for teaching and proper patient care.

Dedicated Critical Care Experience

The stroke fellow attends the SNICU average of 1-2 months a year. The cerebrovascular patients admitted to the SNICU are dually managed by anesthesiologists with neurocritical care training, and by the Vascular Neurology attending. There is no mandatory ICU rotation, however, the fellow becomes proficient in managing critically ill patients during his/her stroke rotations. There is extensive exposure to hemorrhagic and subarachnoid disease since the fellow rotates with the Neurointerventional Team who manages these patients on daily basis. The fellow may rotate electively in the ICU or with the neurosurgical team.

Outpatient Cerebrovascular Clinics

Stroke fellows will acquire ample experience in the outpatient management of complex cerebrovascular cases and determining best strategies for stroke prevention through clinics that are supervised and staffed by a vascular neurologist. Fellows do a ½ day clinic during their elective or secondary stroke 2 week.

Stroke Call

Stroke fellows get exposure to code strokes and telemedicine stroke consultations throughout the whole fellowship. The stroke call frequency is higher during the inpatient stroke months. There is gradual autonomy with constant stroke attending support. The goal is to be comfortable taking stroke call in a busy academic or private institution.

Additional Rotations

The fellows are exposed to several electives. One of the goals of the fellowship is accommodate the schedule to best suit the needs of the fellow. Every individual has specific interests that could be addressed through elective time. The program will support any initiative that the fellow has to improve his/her learning experience. Current possible electives include: Echo, CVICU, neurosurgery, palliative medicine, rehabilitation, among others.

Schedule

We strive to provide fellows a balanced educational experience that will successfully prepare them for independent clinical practice and board certification in Vascular Neurology.  

In addition to core rotations, fellows may request time for elective experiences in several fields:

  • Palliative Care
  • Neurointerventional Surgery
  • Neuroradiology
  • Surgical and Neurocritical Care Unit
  • Echocardiography
  • Cardiovascular Intensive Care

We will work to customize the fellow’s experience to align with their goals for future clinical practice after fellowship.

Research Training

Each vascular neurology Fellow is encouraged to initiate a research project. Research is usually performed within the department, but can take place in another department. The research interests of the faculty are varied, and many projects are in progress. Each faculty profile describes in detail their research interest.

The University of Iowa is part of NIH StrokeNet, a network of 25 nationally recognized stroke centers that has been created to rapidly address the three core features of stroke research and care: prevention, treatment, and recovery. The University of Iowa Regional Stroke Network (StrokeNet) supports additional mentorship training for promising fellows with an interest translational research in stroke.

Rounds, Lectures, and Conferences

  1. Stroke Rounds: these are case-based learning educational rounds in the stroke unit. Stroke rounds are attended by the entire stroke team. It consists of a formal presentation of a recent case in the stroke unit. Cases are presented by residents or medical students and are used as a springboard to discuss one or several cerebrovascular topics.
  2. Monday at 7 a.m. : Neurointerventional M&M conference. Challenging cases are discussed among the Neurointerventional team. Attendance to this meeting is optional, but can be a great educational experience. 
  3. Monday at noon is our vascular neurology teaching conference. Different vascular neurology topics are presented by fellows, faculty and residents. Colleagues from other departments (e.g. cardiology, rehabilitation medicine) are invited to present at this conference. 
  4. Monday at 3 p.m. is “Vascular Fellows Hour”. This meeting is led by Emeritus Professor Harold Adams. Fellows present cases that are discussed by Dr. Adams and the stroke faculty. This is a delightful educational experience aimed at teaching fellows about clinical skills while reviewing the most updated stroke literature. 
  5. Tuesday at noon: Neurology grand rounds.
  6. Wednesday at 4 p.m.: “Interdisciplinary M&M” conferences with our colleagues from neurosurgery and interventional neurology. Every mechanical thrombectomy case is presented and carefully discussed. Cases are presented by both fellows from vascular neurology and neurointerventional surgery. 
  7. First Wednesday of every month: Vascular Neurosurgery Conference. This meeting is optional for the vascular neurology fellows. Challenging cases are discussed among neurosurgery and interventional neurology faculty.

Medical School: Ain Shams University
Residency: University of Minnesota

Why Iowa: It is fortunate to work with highly talented and experienced individuals in the field of vascular neurology. I am ecstatic to learn from cutting-edge discoveries and be current in my understanding of various stroke etiologies while doing my fellowship at the University of Iowa. At this institution, the stroke faculty members significantly integrate the clinical and academic knowledge to further enhance the state of the field. Moreover, working in a hospital that covers a large catchment area like the University of Iowa, allows me to be better prepared for the various clinical contexts I may encounter in both hospital and clinic settings.

Undergraduate: University of the Fraser Valley
Medical School: St. George's University School of Medicine
Residency: University of Iowa

Why Iowa: I chose to remain at the University of Iowa for my vascular fellowship training after having had an excellent training experience as a resident, during which time I developed good relationships with the vascular neurology department and was encouraged to pursue this fellowship. This institution has a very large catchment area and has a high volume of strokes, including a lot of rare pathology. In addition, the history and reputation of the stroke department at the University of Iowa makes for an excellent training experience, and I have no doubt my training here will be of the best quality.
