During a stroke, time lost is brain lost. That’s why the Kingwood Medical Center Stroke Neuro-Interventional Team follows American Stroke Association guidelines for rapid diagnosis and treatment in the first few hours after Stroke symptoms start.
Treatments options for stroke patients are based on the type of stroke. Knowing the time symptoms began is critical to report to the medical team. The damage the brain sustains is dependent on early detection of stroke symptoms occurring and how long ago symptoms started (the onset of symptoms) and the amount of Every minute that transpires brain damage occurs. damage the brain has potentially sustained. An ischemic stroke is caused by a lack of blood supply to the brain. Clearing that blockage and restoring the blood flow is critical to saving the brain. A hemorrhagic stroke is caused by bleeding in the brain, for example from a ruptured aneurysm.
Neuro-Imaging in Treatment Decisions
Emergency CT scanning (CAT scan) is available 24/7 at Kingwood Medical Center. Physicians use advanced 3D road mapping with high-resolution images to quickly determine the type of stroke and start treatment. That may include a combination of medications, surgery and neuro-interventional procedures including mechanical thrombectomy or thrombolysis for ischemic strokes and endovascular coiling for aneurysms. Kingwood has two 64 slice Cat Scan machines which are the most recent technology to image the brain.
Mechanical thrombectomy or Intra-arterial thrombolysis uses a catheter to deliver a small device right to the blood clot that has caused an ischemic stroke. The device either breaks up the clot or removes it – restoring blood flow in a matter of minutes to the affected area of the brain.
In some cases, mechanical thrombectomy is used in combination with IV t-PA. In others, it is used as an alternative to IV t-PA. since t-pA s only effective within a few hours of the onset of symptoms. And, patients at risk for bleeding, (e.g., due to recent surgery), are not candidates for t-PA.
The stroke neuro-interventional teamat Kingwood Medical Center gives physicians the tools they need to improve outcomes for all stroke patients.
Endovascular coiling is a procedure to treat an aneurysm. It is a minimally invasive interventional therapy because it uses a catheter to deliver treatment instead of requiring opening the brain surgery.
An aneurysm is a pocket or bulging area of a blood vessel that can rupture – one of the causes of a hemorrhagic stroke.
In Endovascular coiling , a small metal wire (about the width of a human hair) is coiled into the aneurysm to fill the extra space. This encourages blood to clot around the wire, which keeps blood from flowing into the aneurysm (and therefore keeps the aneurysm from bursting).
Endovascular coiling may be performed alone or in combination with neurosurgery to remove or repair damaged blood vessels. It is also used to treat arteriovenous malformations (AVMs), an abnormal connection between an artery and a vein that can occur in the brain, spine or other areas of the body.
Continuum of Stroke Care
Providing a continuum of care from the Emergency Department through rehabilitation, Kingwood Medical Center offers stroke patients the highest level of care with the advantage of being close to home.
Kingwood Medical Center’s Neuroscience Program is a recipient of the American Stroke Association's Gold Plus and Target Honor Roll Elite and is stroke accredited by the DNV GL Healthcare USA, Inc.and designated as the only Comprehensive Stroke Center in northeast Houston.
