How long will my appointment take?
Our goal is to make sure each patient is seen promptly. Our neurosurgeons typically devote specific days each week in a clinic because they also manage treatment programs, perform surgeries, and teach. For this reason, please allow 2-3 hours for your appointment, especially if unscheduled emergencies delay the doctor.

Can I get an earlier appointment?
Clinics are by appointment only. If your condition deteriorates or changes, please contact our nursing staff, or if urgent attend the nearest hospital emergency department.

What should I do if I’m unable to attend an appointment?
If you are unable to attend an appointment, please cancel as soon as possible. You will be given another appointment if still required. By notifying us, it enables another patient the opportunity to see the doctor.

When can I visit a family member or friend after surgery?
Visiting hours for patients in the Neuro ICU is from 10:00 am to 1:00 pm and 3:00 pm to 8:30 pm. Visitors in the NICU are restricted to next-of-kin only; children are discouraged. 

Ochsner LSU Health Shreveport, in its role as an academic medical center of excellence, provides cutting-edge patient care, conducts world-class clinical and basic research, and offers the highest quality undergraduate and graduate medical education experiences. we provide state-of-the-art neuroscience treatment facilities including Gamma Knife, Neuro ICU, and Interventional Neuroradiology and are recognized as the leader for neuroscience in the South.

What is Gamma Knife?

Since becoming the first in the state of Louisiana to acquire Gamma Knife technology, we have completed over 800 procedures, becoming a leader in stereotactic radiosurgery in the South.

The Gamma Knife procedure stands unique in its ability to reach areas of the brain that remain inaccessible through conventional surgery. This enables patients who were once considered inoperable due to deep-seated abnormalities or critically-located lesions to receive treatment/cure for their disorders.

It also provides additional treatment options to those who have previously undergone conventional treatments or those who do not wish to undergo procedures such as the craniotomy. In addition, it offers treatment options to those who cannot qualify for surgery due to health problems or advanced age.

The Gamma Knife is revolutionary in the treatment of neurological disorders in that it, unlike conventional surgery, requires no incision or opening of the skull. Rather, it uses sources of radioactive Cobalt-60 for generating gamma-ray beams. The microscopic beads are digitally focused onto a specific pre-determined target within the brain, delivering a calculated amount of radiation. Targets are so precise that surrounding healthy tissue near the targeted area receives minimal radiation doses.

Gamma Knife radiosurgery is used for treating a wide spectrum of brain disorders either alone or as an adjunct to conventional surgery, such as vascular malformations, benign tumors, malignant tumors, movement disorders, trigeminal neuralgia.

About Stroke Care

Award-winning stroke care

Ochsner LSU Health Shreveport is certified by The Joint Commission as a Thrombectomy-Capable Stroke Center. If you or your loved one is in need of care following a stroke, we provide high-quality, state of the art stroke care.

Stroke Care

Clinical excellence combined with professional and compassionate delivery of care defines Ochsner LSU Health Shreveport’s stroke program and sets us apart. Our stroke teams-comprised of board certified physicians, nurses, therapists, and social workers-offer an integrated approach to diagnosis, treatment, and prevention of and education about stroke.

Time is critical when it comes to stroke. When a patient displays stroke-like symptoms, early diagnosis and treatment is crucial. We are focused on providing rapid diagnosis using the treatment guidelines developed by the American Heart Association/American Stroke Association Get With the Guidelines-Stroke program to treat stroke patients. Our hospital is equipped:

  • To provide brain-imaging scans which are available 24-hours a day, 7 days a week.
  • With a rapid response stroke team comprised of specially trained physicians and nurses to administer immediate stroke care using clot-busting medications and/or mechanical clot removal therapy when appropriate.

During and after a hospital stay we provide or connect patients with services needed to begin their recovery and make continued progress. We offer:

  • Stroke education for patients and their families to help them understand stroke, rehabilitation, and prevention.
  • Rehabilitation and therapy services (including physical, speech, and occupational therapy) to help patients regain movement and function abilities
  • Nutrition services to help patients make positive lifestyle decisions.
  • Social work services to help patients and families cope with change.

We also help patients improve their health through providing information on:

  • Risks factors for stroke.
  • What you should do if you are at increased risk for stroke.
  • Warning signs of stroke.
  • Becoming more informed and involved in their health care.
  • Act quickly and call 911 if just one of the stroke-like symptoms come on suddenly.

Thrombectomy Care (Mechanical Endovascular Reperfusion)

Stroke patients at Ochsner LSU Health can benefit from an extended 4.5 hour tPA treatment window and can receive endovascular treatment up to 24 hours after symptom onset.

We feature an advanced Neurointerventional Biplane Angiography Suite and the latest thrombectomy devices, both of which allow physicians to perform the most complex endovascular interventions.

Scope of Service

The stroke program cares for those who have suffered an ischemic or hemorrhagic stroke.
