Background
Multiple studies have shown a clinical benefit of thrombectomy in acute ischaemic stroke, but most of them excluded octogenarians. The purpose of this study was to compare the outcomes between octogenarians and younger patients after thrombectomy.
Materials and methods
One hundred and sixty-six patients with large cerebral artery occlusion and consecutive thrombectomy were evaluated and divided into two patient age groups: younger than 80 years and older than 80 years. We compared recanalization rates, complications experienced, disability, death after discharge and at a 90-day follow-up between these age groups.
Results
Sixty-eight percent of octogenarians and 72 % of younger patients were registered with successful recanalization (p = 1.0). There was no significant difference in symptomatic intracerebral haemorrhage between the groups (p = 0.32). However, octogenarians had a significantly lower rate of good clinical outcome (24 % vs. 48 %; p = 0.008) and a higher mortality rate (36 % vs. 12 %; p = 0.0013).
Conclusion
Octogenarians have a lower chance of good clinical outcome and a higher mortality rate despite successful recanalization. Nevertheless, 24 % of octogenarians were documented with mRS ≤2. As this age group of octogenarians will grow prospectively, careful patient selection should be mandatory when considering octogenarians for thrombectomy.
Key Points
• Careful patient selection for thrombectomy should be mandatory in octogenarians.
• Octogenarians have a higher mortality rate despite successful recanalization.
• Nearly one-third of octogenarians were documented with a good clinical outcome.
