The promising results of the Solitaire FR With the Intention for Thrombectomy (SWIFT) trial recently led to Food and Drug Administration (FDA) approval of the Solitaire FR stent retriever device for recanalisation of cerebral vessels in patients with acute ischaemic stroke.Objective
To report the early postmarket experience with this device since its FDA approval in the United States, which has not been previously described.Methods
We conducted a retrospective analysis of consecutive acute ischaemic strokes cases treated between March 2012 and July 2012 at 10 United States centres where the Solitaire FR used as a single device or in conjunction with other intraarterial endovascular approaches.Results
A total of 101 patients were identified (mean age, 64.7 years; mean admission National Institutes of Health Stroke Scale [NIHSS] score, 17.6). Intravenous thrombolysis was administered in 39% of cases; other endovascular techniques were utilised in conjunction with the Solitaire FR in 52%. Successful recanalisation (Thrombolysis in Myocardial Infarction 2/3) was achieved in 88%. The rate of symptomatic intracranial haemorrhage within the first 24 hours was 15%. In-hospital mortality was 26%. At 30 days, 38% of patients had favourable functional outcome (modified Rankin scale score ≤2). Severity of NIHSS score on admission was a strong predictor of poor outcome.Conclusion
Our study shows that a variety of other endovascular approaches are used in conjunction with Solitaire FR in actual practice in the United States. Early postmarket results suggest that Solitaire FR is an effective tool for endovascular treatment of acute ischaemic stroke.Disclosures
