The following is a Q & A with Dr. Edgard Pereira, a specialist in neurointerventional surgery and interventional radiology at JFK Medical Center.
Q: What is an interventional neurologist? What kind of training or background is required?
A: An interventional neurologist is a specialist who treats neurological diseases using catheters and x-ray imaging. It requires many years of training after medical school. It takes four years of residency in Neurology, then two to three years in critical care neurology and/or vascular neurology, then two years in a neurointerventional fellowship.
Q: What kinds of conditions do interventional neurologists treat?
A: The neurointerventionalist treats many diseases, such as brain aneurysms, brain and spinal cord vascular malformations, facial vascular malformation, brain and spine tumors, acute stroke, and carotid and cerebral artery blockages. He also treats spine fractures with kyphoplasty.
Q: What’s the most common condition you treat? How can patients prevent developing this condition?
A: The most common conditions treated are brain aneurysms and vascular malformations, acute stroke that cannot be treated with IV clot busters, and carotid artery blockage. Many of these conditions have risk factures for their development. Atherosclerosis plaque, for instance, is closely related to high blood pressure, diabetes, high cholesterol and use of tobacco. A healthy diet consisting of vegetables, fruits and plenty of water, regular daily exercise, and avoiding consumption of alcohol should be everybody’s goal. Needless to say, avoiding use of tobacco is a must. Also, if there is a close relative such as a sibling or parent who has suffered from a brain aneurysm, one should have a screen MRI/MRA or CAT scan.
Q: Neurointervention uses thin tubes called catheters to treat patients. What are the advantages of this kind of procedure? What were previous treatment options?
A: One of the main advantages is that this is a minimally invasive approach to a variety of conditions. For instance, someone who has a brain aneurysm can be treated through a small skin cut at the groin, be sent home the very next morning and return to work in the next day or so. Many of the neurointerventional techniques offer treatment that would not be possible otherwise, or would carry a high risk of terrible complications. Take, as an example, someone with a stroke caused by a blood clot blocking a major brain artery. Even with medications to dissolve the blood clot, many stroke patients continue with the blockage. In those cases, we have now special catheters and devices that allow the interventional neurologist to re-open the blocked artery and re-establish blood flow, preventing the progression of or reversing the stroke. In the past, large brain aneurysms that can now be treated successfully with special glue or stents would require extensive open surgery, or even permanent occlusion of a brain artery.
Q: What is the connection between heart health and neurological conditions like stroke and aneurysm?
A: High blood pressure, high intake of alcohol and consumption of tobacco are not only risk factors for heart attack, but also for stroke. Many patients with irregular heartbeat and myocardial infarction are also at high risk for stroke. Some diseases of the blood vessels may also predispose one to the development of brain aneurysms.
Q: After neurointerventional surgery, how quickly—and to what extent—do patients recover?
A: In most cases, he or she can be discharged home the next day, and return to his or her normal activities one or two days later. Some patients with stroke may require some weeks of rehabilitation, depending on their initial condition.
Q: How have these neurointerventions changed the prognosis for patients with spinal injuries and illnesses (e.g., spinal tumors)?
A: Many conditions that in the past could not be effectively treated by open surgery, or had no surgical option, can be now managed by neurointerventional techniques. For being less invasive, neuroinervention offers a faster and more complete recovery.
Q: What’s one thing that you wish patients knew before they came to see you?
A: He or she should look for information on the Internet; and discuss it with his or her primary care provider or with friends, so the expectations are based on rational grounds.
Q: Please share a patient story, where neurointerventional surgery significantly improved the patient’s prognosis, quality of life, etc.
A: I once treated a young woman post-partum (following delivery of a baby),who came to our emergency room in a coma because of a massive stroke. She arrived within a few hours of the stroke’s onset. She was immediately placed in the angio room and had a catheterization, which showed a blockage of a main artery in the back of her brain. A device called Merci, like a corkscrew, was then used to remove the blood clot and re-open her artery. This girl was sent home with her newborn a few days later, and she was completely normal.
Q: Why did you choose to go into this field?
A: I always believe in cutting-edge medicine to help my patients, and I believe that minimally-invasive procedures are the future of surgery. About 20 years ago, I foresaw that procedures used by cardiologists, such as stents, could be used in the brain to treat patients with stroke. I remember being criticized when I became one of the first neurologists in the U.S. trained in neurointervention. This is a wonderful specialty, full of rewards that give me tremendous professional and personal satisfaction.
