In this registry analysis of EVT-treated anterior-circulation occlusion, extensive infarcts (ASPECTS 1-2) had a challenging prognosis, but an acceptable outcome and non-institutional living remained achievable in a relevant minority, particularly after successful reperfusion; no independent association of infarct group with outcome was detected, and without a medically managed comparator the data describe prognosis rather than treatment effect.
Key Findings
Results
Of 18,069 screened patients in the German Stroke Registry-Endovascular Treatment, 889 were analysed, and none had ASPECTS 0.
ASPECTS 1-2 (extensive infarct) group: n = 89.
ASPECTS 3-5 (large infarct) group: n = 800.
Analysis was a retrospective analysis of patients with anterior-circulation occlusion treated with EVT.
Results
Patients with extensive infarcts (ASPECTS 1-2) had high mortality and a minority achieved acceptable functional outcome at 90 days.
20.2% achieved mRS 0-3 within 90 days.
55.1% died within 90 days.
The primary outcome was the ordinal 90-day mRS distribution.
Results
After adjustment including successful reperfusion, no statistically significant association was detected between infarct group (ASPECTS 1-2 vs 3-5) and 90-day functional outcome.
The authors state an independent association of infarct group with outcome was not detected.
Results
Successful reperfusion was strongly associated with better 90-day functional outcomes.
Ordinal mRS shift: cOR 3.68; 95% CI, 2.31-5.85.
mRS 0-3: aOR 4.10; 95% CI, 2.45-6.86.
Authors note acceptable outcome remained attainable in selected extensive-infarct patients, particularly after successful reperfusion.
Results
Among survivors with available data, quality of life was numerically lower in the ASPECTS 1-2 group than the ASPECTS 3-5 group.
Median EQ-5D-3L utility index was 0.445 vs 0.541.
Data available for n = 27 (ASPECTS 1-2) / 324 (ASPECTS 3-5).
Results
About half of survivors with available living-condition data lived at home in both infarct groups.
51.5% vs 50.9% lived at home.
Data available for n = 33 / 411.
Non-institutional living remained achievable in a relevant minority of extensive-infarct patients.
Conclusions
The data describe prognosis rather than treatment effect because no medically managed comparator was available.
The study was a retrospective registry analysis of EVT-treated patients only.
Authors conclude acceptable outcome remained attainable in selected patients with extensive infarction.
What This Means
This study used a German registry of stroke patients who underwent clot-removal procedures (thrombectomy) for blockages in the brain's front circulation. It compared patients with very extensive early brain damage on CT scans (scores of 1-2 on the ASPECTS scale) with those with large damage (scores 3-5). Of 889 patients analysed, 89 were in the extensive group.
Outcomes in the extensive-damage group were difficult: 55.1% died within 90 days, but about one in five (20.2%) reached a level of function considered acceptable (able to walk with or without help, mRS 0-3). Among survivors with available data, about half lived at home in both groups. After accounting for other factors, including whether blood flow was successfully restored, the study did not detect a statistically significant difference in outcome between the two damage groups. Successful restoration of blood flow was strongly linked to better outcomes.
This research suggests that some patients with extensive early damage may still reach acceptable outcomes after thrombectomy, particularly if blood flow is restored. However, the study had no group of patients treated with medication alone, and the extensive group was small with limited quality-of-life data, so it describes expected outcomes rather than proving the procedure's benefit.
