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 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 the STAR, emphasizes that pre-existing disability alone should not disqualify patients from treatment. He states, "Every patient deserves the opportunity to be considered for the treatment most likely to help them recover from a stroke."
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. This finding underscores the potential for thrombectomy to improve outcomes for a broader range of stroke patients.
In my opinion, this study is a significant advancement in our understanding of stroke treatment. It challenges traditional assumptions about patient eligibility and highlights the importance of personalized medicine in stroke care. By considering individual patient factors, we can improve treatment outcomes and provide hope for a wider range of stroke patients.
