Impact of reperfusion on thrombectomy outcomes in patients with pre-stroke disability
Clinical Scorecard: Effects of Reperfusion Success on Thrombectomy Results in Patients with Pre-existing Stroke Disability
At a Glance
Category Detail
Condition Mechanical Thrombectomy for Stroke Key Mechanisms Reperfusion success and first-pass effect (FPE) impact functional outcomes. Target Population Patients with anterior circulation large-vessel occlusion stroke and pre-stroke disability (mRS 0-4). Care Setting Multicenter stroke centers in the United States.
Key Highlights
30.1% of patients undergoing MT had pre-stroke disability. Successful reperfusion linked to improved 90-day mRS across baseline disability levels. FPE consistently beneficial regardless of pre-stroke disability. No significant interaction between reperfusion and baseline disability regarding 90-day mRS. Outcomes comparable between neurological and non-neurological sources of disability. Guideline-Based Recommendations
Diagnosis
Assess pre-stroke disability using modified Rankin Scale (mRS). Evaluate degree of reperfusion using eTICI grading. Management
Consider mechanical thrombectomy for selected patients with pre-stroke disability. Aim for successful reperfusion (eTICI 2b-3) during MT. Monitoring & Follow-up
Monitor functional outcomes at 90 days post-thrombectomy using mRS. Evaluate discharge mRS to assess immediate outcomes. Risks
Consider variability in selection practices across centers. Be aware of the potential for differing outcomes based on disability etiology. Patient & Prescribing Data
Patients with anterior circulation large-vessel occlusion stroke and varying degrees of pre-stroke disability.
Successful reperfusion is associated with better functional outcomes, regardless of baseline disability.
Clinical Best Practices
Utilize ordinal logistic regression to analyze outcomes based on baseline mRS. Adjust for confounding factors such as age, NIHSS, ASPECTS, and occlusion site. Related Resources & Content
