Intracranial stenting are completely safe and most useful in preventing further debilitating stroke conditions
Most people know when they hear the word stent that it is associated with your heart. However, it is not widely known that stents can also be placed into the blood vessels of the brain. According to experts, brain sor intracranial stenting—help open blocked arteries in the brain to restore blood flow and help prevent a debilitating stroke.
“These blockages for which stenting is possible can be equated to blockage of follows-mediated blood supply to the brain that may cause or has caused a stroke,” Dr. Vinit Banga, Director of Neurology and Head Neurointervention at Fortis Escorts Hospital, told Times Now.
Brain stroke is the third leading cause of mortality worldwide and is set to become topmost in disability worldwide, according to studies.
Ischemic stroke, the most common form of stroke, occurs when a blockage in an artery—often from a blood clot or a fatty deposit due to atherosclerosis—interrupts blood flow to an area of the brain. Experts say only a fraction of patients experiencing an ischemic stroke are treated with a potentially life-saving drug that can dissolve the clot.
How is a brain stent fitted?
According to Dr. Banga, stents are fitted using a revascularisation procedure, which extensively uses an imaging technique known as digital subtraction angiography to visualize the blood vessels and a guidewire to maneuver a balloon-tipped catheter to the location of the blockage in the middle cerebral artery.
Once the balloon is inflated, deflated, and withdrawn, a stent is inserted to help the artery remain open. Patients with a favourable three-month outcome following the procedure were able to live independently and perform normal daily activities.
“In every case, stroke, when presented to us, usually evaluates related to blockages in the vessels supplying blood to the heart. Well, in this case, we begin elaborately knowing about each patient's stroke cause—occlusion or haemorrhage—with care to ascertain narrowing, giving condition in the neck- or brain-level main blood supply to the brain,” he said.
“This was also overlooked in stating their etiology—would probably have unfurled for treating such with help of stents that would be opened during the blood vessel narrowing-stroke disabling future ones,” Dr. Banga added.
How do the stents work?
Given inert materials, stents safely run with hinged blood vessels in the urine puddle or blood-stopping with puta-Nelson Movement canyon opening over the skin or brain drill with dimples pushes through a smartly small prick either in the leg or arm—known as a neurovascular intervention. Once safely deployed, blood supply, presently open toward the skull, anatomically just will be re-established, wherein treatment plays a part toward received forward-observed improvement of both.
Blood thinners, even thereafter, are significant to keep away from thrombus or clotting, composing stents inside; nothing too deep.
Brain stents are particularly useful in those who get repeated strokes despite adequate medication because of the critical narrowing of the blood vessel feeding blood to the brain.
