Stroke patients with disabilities may benefit from thrombectomy treatment, according to new research presented at the Society of NeuroInterventional Surgery's 23rd Annual Meeting. The study, "Impact of Successful Reperfusion on Functional Outcomes After Thrombectomy in Patients with Pre-stroke Disability," analyzed data from 781 patients with pre-existing disabilities who underwent endovascular thrombectomy (EVT) for large vessel occlusion stroke between 2016 and 2025 through the international Stroke Thrombectomy and Aneurysm Registry (STAR).
The findings challenge the notion that patients with disabilities have too little to gain from thrombectomy. Researchers found that successful restoration of blood flow (reperfusion) was associated with less functional decline, greater odds of improvement from baseline, and lower mortality among these patients. Patients with successful reperfusion were significantly less likely to experience worsening disability (62.2% vs. 79.6%) and less likely to die within 90 days of their stroke (39.8% vs. 57.7%).
This study highlights the importance of considering individual patient factors when determining eligibility for thrombectomy. Ali Alawieh, MD, PhD, senior author of the study and co-founder of STAR, emphasizes that pre-existing disability alone should not disqualify patients from treatment. He states, "When we measured recovery against each patient's own baseline, they held onto their function comparable to patients who were independent before their stroke. Pre-existing disability alone shouldn't close the door on treatment."
The research also compared patients with pre-existing disabilities to those with little or no disability before stroke. While patients with pre-stroke disabilities experienced poorer overall outcomes and higher mortality, they still derived meaningful functional benefit from successful reperfusion. Ali Tfaily, MS, Doctoral Fellow at Emory University Laney Graduate School and primary author of the study, emphasizes the importance of considering all patients for thrombectomy, stating, "Every patient deserves the opportunity to be considered for the treatment most likely to help them recover from a stroke."
This study has significant implications for stroke treatment, suggesting that carefully selected patients with pre-stroke disabilities can benefit from thrombectomy. It raises the question of whether current eligibility criteria for thrombectomy are too narrow and may exclude potentially treatable patients. Further research is needed to refine these criteria and ensure that all eligible patients receive the most effective treatment.
In my opinion, this research is a game-changer for stroke treatment. It challenges long-held assumptions about patient eligibility and highlights the importance of personalized medicine in stroke care. By considering individual patient factors, we can improve outcomes and give hope to patients with disabilities who were previously considered ineligible for thrombectomy. This study should prompt a reevaluation of current treatment guidelines and encourage more inclusive approaches to stroke care.
