The Stroke and Cerebrovascular Diseases and Stroke section focuses on the diagnosis and treatment of vascular-mediated damage to the central nervous system (CNS). While ischemic and hemorrhagic strokes are the most common condition managed by the Stroke and Cerebrovascular Diseases and Stroke section, we have a long history of caring for patients with conditions such as Moyamoya disease, carotid/vertebral artery dissections, intracranial cerebral atherosclerosis and CNS vasculitis.
The Cerebrovascular Diseases and Stroke program has been in practice since 1988. Our team cares for patients in the inpatient and outpatient services at Parkland Memorial Hospital and William P. Clements, Jr. University Hospital within the UT Southwestern system.
The Cerebrovascular Diseases and Stroke section conducts local and national clinical trials, registry, and outcomes research, including landmark studies in the care of patients with stroke and cerebrovascular diseases.
We have conducted trials that have helped answer fundamental questions regarding carotid disease, intracranial large vessel disease, acute care of stroke patients, effect of glucose control, hypertension in acute stroke patients, and the use of antiplatelet and anticoagulant medications in the care of stroke patients.

For decades, our faculty has actively been teaching medical students and fellows in the acute care of stroke patients 24/7 coming to our institutions of care from the DFW and North Texas areas. Our teaching has included the management of complex cerebrovascular disorder and the prevention of recurrent stroke.
The Cerebrovascular Diseases and Stroke section is committed to providing comprehensive, compassionate, efficient, high-quality care to our patients and their families. We are consulted for the assessment of acute stroke patients and the care of other conditions including:
- CNS Vasculitis
- Fibromuscular Dysplasia
- Moyamoya disease
- Extracranial Carotid and Vertebral Atherosclerotic Disease
- Intracranial Atherosclerotic Disease (ICAD)
- Carotid and Vertebral Dissections
- Stroke in patients with cardiac conditions of PFO and Atrial Fibrillation
- Cerebral Venous Sinus Thrombosis
Primary and Collaborative Services
The Cerebrovascular Diseases and Stroke section offers Transcranial and Carotid Duplex in the diagnostic assessment of patients with stroke. We often collaborate with departments including Cardiology, Hematology, Neurosurgery, Neurointerventional, Rheumatology, and Physical Medicine and Rehabilitation in the patient care continuum.
