This study evaluated the clinical outcomes and mortality rates among nonagenarians treated with mechanical thrombectomy for acute ischemic stroke. The study found a high rate of successful recanalization but also a significant mortality rate. Long-term outcomes were predicted by stroke severity and time of hospital arrival.
Background: Mechanical thrombectomy (MT) has established its role as a first-line treatment of acute ischemic stroke due to large vessel occlusions (LVO). However, patients older than 85 or even 80 years of age are commonly excluded from large randomized controlled stroke studies as this group was found to be associated with significantly poorer clinical outcome and increased mortality compared to younger patients. The aim of this study was to evaluate clinical and procedural factors associated with clinical outcome and mortality among nonagenarians with acute ischemic stroke treated with mechanical thrombectomy. Materials and Methods: This retrospective, single-center study was conducted on 38 patients with LVO treated with MT. Clinical features including baseline results, radiological imaging, procedural details and outcome results were documented and evaluated. Recanalization was assessed according to the TICI score. The clinical condition was evaluated on admission (NIHSS) and after 3 months (mRS). Results: The rate of successful recanalization (TICI >= 2b) was 84.2 % (32/38). Symptomatic intracranial hemorrhage (sICH) was observed in 3 (7.9 %) patients. After 90 days, the mortality rate was 47.4 %. Favorable clinical outcome (mRs 0-2) was regained in 28.9 % of the patients (11/38). Poor clinical outcome (mRs<2) was observed in 9 patients (23.7 %). Conclusion: Very elderly patients with LVO should not be excluded from MT even if prognosis for good clinical outcome in this age group remains low and the procedure is more challenging. Long-term outcome is predicted by stroke severity (baseline NIHSS and occluded vessel) and hospital arrival time.
