Introduction/Purpose The recent results of the SWIFT and TREVO-2 trials demonstrated better recanalisation and efficacy rates with mechanical thrombectomy; however, its efficacy in the elderly population is poorly understood. Here, we report the effect of age on clinical and angiographic outcome within the North American SOLITAIRE-FR Stent-Retriever Acute Stroke (NASA) Registry.

Methods The investigator-initiated NASA Registry recruited sites within North America to submit data on consecutive patients treated with Solitaire-FR. Good clinical outcome was defined as a 90-day mRS ≤2. Successful recanalisation was defined as TIMI ≥2. SICH was defined as any parenchymal haematoma, SAH, or IVH associated with a worsening of the NIHSS score by 4 or more within 24 hours. Age influence on outcomes was assessed by comparing the means between outcomes and dichotomising the age into ≤80 or ≥80 years of age. A standard medical care cohort was not available for comparison in this study.

Results 343 patients underwent treatment using the SOLITAIRE-FR device in 24 centres. The mean age for those with good clinical outcome at 90 days was 64.9 ± 15 versus 69.2 ± 14.4 years (P=0.02). Only 26.6% (17/64) of patients >80 years of age had a 90-day mRS ≤ 2 versus 45.3% (111/245) of those ≤80 years of age (p=0.007, OR 1.34, 95%CI 1.2-1.6). Mortality was 42.2% (27/64) and 27.4% (67/245) in the >80 and ≤80 age groups, respectively. No difference in good outcome or mortality between female and males was observed in this population (90-day mRS≤ 2 was 41.3% (62/150) with mortality of 28% (42/150) versus 42.1% (69/164) with mortality of 32.3% (53/164) in females and males, respectively). Multivariate logistic regression analysis (adjusting for age, sex, race, baseline-NIHSS, occlusion site, initial BP, time from symptoms onset to groin puncture, and revascularisation), showed age, baseline-NIHSS, initial systolic blood pressure and revascularisation status as an independent predictors of both good outcome and mortality.

Abstract O-025 Table 1

Conclusions In the NASA registry, patients >80 years of age who were treated with the Solitaire-FR device demonstrated a significantly lower rate of good clinical outcome and increased mortality at 90-days, compared to the those in the ≤ 80 years of age group.
