Endovascular thrombectomy for ischemic stroke

The standard of care for patients with acute stroke of the anterior circulation and large vessel occlusion is the combined treatment with intravenous rt-PA (recombinant tissue-type plasminogen activator) and endovascular thrombectomy. The therapy is highly effective while reducing functional deficits and long-term disability. International guidelines recommend thrombectomy during the first 6 h after symptom onset, but new evidence supports its use in selected patients within a time window of up to 24 h. Eligible patients show a clinical core mismatch, i. e. severe neurologic deficits contrasting to a small core of cerebral infarction. Future research questions regard the treatment of vessel occlusion at the M2 segments as well as the best anesthetic management during the intervention. The infrastructure of stroke care especially in rural areas is based on the drip-and-ship paradigm that implies emergency treatment with the start of intravenous thrombolysis at the nearest hospital followed by transport to an interventional center in case of large vessel occlusion.
