AIM: Recent trials have established the benefit of endovascular treatment (EVT) for patients with acute ischemic stroke (AIS) due to large artery occlusion (LAO). However, older patients were often excluded from trials. EVT outcomes were retrospectively compared between octogenarians and younger patients treated for LAO in a tertiary hospital.
PATIENTS AND METHODS: A total of 199 consecutive patients with anterior circulation AIS that underwent EVT between 2009 and 2015 in the Kuopio University Hospital were included. Patients were dichotomized into younger (<80 years, N=162) and older (≥80 years, N=37) groups. Baseline, imaging, and procedural characteristics, the 3-month modified Rankin Scale (mRS), and 1-year mortality were assessed. To conduct a number-needed-to-treat (NNT) analysis, data on age-dichotomized control groups from a meta-analysis were acquired.
RESULTS: Compared to younger patients, older patients exhibited atrial fibrillation (57% vs. 21%, p<0.01) and coronary artery disease (49% vs. 20%, p<0.01) more frequently and Internal Carotid Artery (ICA) occlusion less frequently (22% vs. 55%, p<0.01). Similar proportions of patients received preprocedural intravenous recombinant tissue-type plasminogen activator (r-tPA; 57% vs. 67%), general anesthesia (35% vs. 41%), and reperfusion (Thrombolysis in Cerebral Infarction scale 2b/3; 76% vs. 75%). Older patients had more complications during hospitalization (41% vs. 24%, p=0.034), higher 3-month mRS values (4.0±2.3 vs. 2.8±1.9, p<0.01), fewer favorable mRS values (mRS≤2: 27% vs. 52%, p<0.01), and higher 3-month (46% vs. 10% p<0.01) and 1-year mortality (49% vs. 11%, p<0.01). The NNT to achieve an additional patient with an independent outcome (mRS≤2) was 12 among older and six among younger patients.
CONCLUSION: Despite a poor recovery rate, octogenarians benefitted from EVT for AIS, with a NNT comparable to that of younger patients treated with intravenous r-tPA.
