General Anesthesia Versus Sedation During Intra-arterial Treatment for Stroke

Registration Number
NCT02822144
Lead Sponsor
Rennes University Hospital
Brief Summary

In France, the annual incidence rate of acute ischaemic stroke is around 150 000 patients, 65 % of whom keep long-term disability. Several multicentric randomized controlled trials have shown the benefit of a mechanical thrombectomy in the acute phase of ischaemic stroke on functional disability, compared to a medical treatment alone (thrombolysis).

The timeliness of revascularisation is an essential factor of good prognosis. This intra-arterial treatment, associated with thrombolysis if applicable, is the reference treatment of large-vessel occlusion. The stillness of the patient is required to control the safety of the recanalization. Currently, either a general anesthesia or a sedation can be performed.

Several studies have shown a trend to superiority of the sedation but none was conducted with a high level of proof methodology.

The aim of our multicentric randomized controlled trial is to compare sedation and general anesthesia during intra-arterial thrombectomy for an acute ischaemic stroke in the anterior cerebral circulation. The main outcome will be the efficacy on the functional neurological prognosis at 3 months.
