New research presented today at the 19th annual meeting of the Society of NeuroInterventional Surgery (SNIS) shows that thrombectomy, a minimally invasive procedure usually reserved for treating a severe type of stroke known as large-vessel occlusion (LVO) , achieves positive results for people suffering from other types. of strokes Expanding eligibility for this life-saving treatment will give more patients a better chance for successful recovery and rehabilitation after stroke.
In the first study, “Technical and clinical outcomes in distal occlusion thrombectomy by first-line technique: a multicenter study,” researchers analyzed the outcomes of nearly 7,500 patients undergoing thrombectomy for different types of stroke at 32 centers of the United States. They found that the clinical outcomes of distal vessel occlusions (DVOs) are comparable to those experiencing LVOs. DVOs are clots located in small arteries higher up in the brain and are not usually treated by thrombectomy.
“Thrombectomy has changed the way medical professionals care for stroke patients,” said Ali Alawieh, MD, Ph.D., lead study author and neurosurgery resident at Emory School of Medicine. “If more stroke patients can experience this life-saving treatment, we want to make sure that happens.”
In the second study, “Real-World Outcomes of Endovascular Thrombectomy for the Treatment of Acute Basilar Artery Occlusion in the United States: Results from the BArONIS Study,” nearly 4,000 patients experiencing acute basilar artery occlusion basilar artery, which occurs when the basilar artery is blocked. were treated with thrombectomy. This artery is the main artery in the back of the brain. It carries oxygen to the blood in the brainstem, cerebellum and occipital lobes. There is little research on the effectiveness of thrombectomy when dealing with this type of stroke, but results showed that patients who underwent this procedure achieved more favorable outcomes.
“Patients who receive a thrombectomy increase their life expectancy by five years compared to patients who do not. For every 10 minutes saved by having a thrombectomy, patients experience an additional month of disability-free life. In addition , basilar artery occlusion stroke is associated with 40% mortality and of survivors, 80% have severe deficits,” said lead author Fawaz Al-Mufti, MD, an interventional neurologist at the Westchester Medical Center and Assistant Dean of GME Research at New York Medical College. “This is particularly true for patients with basilar artery occlusion stroke with high NIHSS, where endovascular thrombectomy portends a mortality and disability benefit.”
