Endovascular thrombectomy improves outcomes for large infarct strokes
Recent findings assess how endovascular thrombectomy performs in clinical practice for patients with large ischemic strokes.
Endovascular thrombectomy (EVT) effectively treats acute ischemic strokes with large infarct cores, according to recent research showing clinical outcomes align with randomized controlled trials.
Despite advancements in stroke therapies, about one in four stroke survivors face significant disabilities. EVT has reduced both disability and mortality rates for ischemic stroke, especially in large vessel occlusions. Its application is often restricted to patients meeting specific criteria, such as a minimum National Institutes of Health Stroke Scale (NIHSS) score and neuroimaging results indicating a large vessel occlusion.
A new study published in the International Journal of Stroke evaluated data from 198 participants within the TENSION trial and the German Stroke Registry. Researchers found that EVT could improve outcomes for patients with larger infarct cores, defined by the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) ranging from 3 to 5. Patients receiving EVT had better outcomes compared to those treated medically alone.
While the findings are promising, discrepancies exist between trial participants and those in everyday practice. The study noted that the median ASPECTS was lower in routine cases compared to the TENSION cohort, suggesting differences in infarction severity. After employing propensity score matching, outcomes were similar: both groups showed no statistically significant difference in achieving independent ambulation at 90 days post-stroke. The adjusted odds ratio indicated no advantage for patients treated within the TENSION trial compared to those from the German Registry.
Winkelmeier et al., who led the study, noted that while clinical outcomes were consistent, the extent to which trial criteria are utilized in clinical settings remains uncertain. About half of the patients in the German Stroke Registry met the TENSION trial eligibility, highlighting a gap between research findings and clinical application.
The study also raises concerns regarding selection bias and the representativeness of the matched subgroup. Limitations include the study’s focus within a resource-rich environment, which may not reflect broader healthcare systems, and the lack of subgroup analyses based on demographic data.
While the findings suggest that EVT can benefit patients with significant infarction, further research is necessary to ensure consistent application of trial protocols in clinical settings. As stated in the study, “the findings are encouraging,” supporting ongoing exploration of EVT’s role in stroke management.
