North Oaks leads the way in stroke treatment on Northshore
HAMMOND---The treatment window for the most common type of stroke has expanded from three hours to 24 hours at North Oaks Medical Center due to enhanced interventional radiology capabilities made possible by the addition of Dr. Zachary Liner, a Neuroradiologist, to the medical staff.

The hospital, which is a certified Primary Stroke Center through The Joint Commission, is the only facility on the Northshore currently offering a lifesaving procedure called intracranial mechanical thrombectomy.

This minimally invasive procedure is now part of the hospital’s arsenal of effective treatment options for ischemic strokes, the most common type. When an ischemic stroke occurs, the blood supply to the brain is blocked by a blood clot or plaque. Without a healthy blood supply, the brain doesn’t receive the oxygen and nutrients needed to work properly, and brain tissue begins to die.

Historically, a clot-busting drug called tPA has been used to treat this type of stroke, but it must be administered within three to four hours of onset of symptoms.

In this regard, intracranial mechanical thrombectomy is a game changer because it widens the treatment window up to 24 hours after the initial appearance of stroke symptoms.

The procedure is made possible by image-guided catheters and a wire cage device, called a stent retriever, which are used to remove blood clots in large vessels in the brain. Liner threads the catheter through an artery in the groin up to the blockage in the brain. He then deploys the stent retriever through the clot and removes the stent retriever with the captured clot through the catheter that was placed in the artery.

“Ideally, the procedure should be done within six hours of symptom onset,” explains Liner. “However, a national study called the DAWN Trial and published in The New England Journal of Medicine, has proven it can still be effective if done within 24 hours of onset under certain conditions. This gives us a greater chance of helping people who wake up with stroke symptoms and don’t really know when they first started. More importantly, it’s more likely that patients will regain movement, speech or other abilities lost.”

Glen Sterling of Tangipahoa is one such patient who has made a total recovery from his stroke thanks to this procedure. He was eating breakfast when his wife Charlene noticed the warning signs of a stroke. His lips looked droopy, his left side was limp, and he was slurring his words. She called 911, and within 10 minutes, first responders were on scene, confirmed he was having a stroke and made the call to airlift him to North Oaks Medical Center, where the Interventional Radiology team ordered a CT scan to confirm that Sterling was a candidate for intracranial mechanical thrombectomy. The procedure took about 53 minutes, and when Sterling awoke, he showed no visible signs of the stroke. Two days later, Sterling was able to return home thankful that debilitating outcomes, like paralysis, were avoided.

A Hammond native, Liner has returned home to practice after completing a fellowship in Interventional Radiology through Baylor Scott & White Health in Temple, Texas with an additional fellowship year in Interventional Neuroradiology through the University of California – San Francisco. He earned his medical degree at Louisiana State University School of Medicine in New Orleans, and completed an internship in General Surgery at Emory University and a residency in Diagnostic Radiology at Rochester General in New York.

Now with the necessary team and infrastructure in place, North Oaks Medical Center is aiming to develop Interventional Radiology services even further. The hospital is partnering with the North Oaks Foundation to purchase a $1.8 million neurointerventional biplane unit that can capture two- and three-dimensional images of the brain, arteries and spine with one single injection of X-ray dye. The foundation has committed to raising $500,000 toward the purchase.

Stroke is the No. 4 cause of death in Louisiana, according to the American Heart Association/American Stroke Association. Time is brain when it comes to stroke care as evidenced by the fact that someone suffers a stroke every 40 seconds in the U.S. Someone dies due to stroke every four minutes, and nearly one million people suffer a new or recurrent stroke each year.

People having a stroke may experience some or all of the following warning signs, some of which can be subtle: sudden numbness or weakness of the face, arm or leg, especially on one side of the body; sudden confusion, trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance or coordination; and sudden severe headache with no known cause.

To easily remember the sudden signs of stroke, use the acronym FAST – Face, Arms, Speech, Time. When you spot these signs, it’s time to call 911 for help.
