New Imaging Strategies During Acute Stroke Treatment

Mechanical extraction of clots (“mechanical thrombectomy”) with specialized catheters has become the standard of care for treating stroke patients with a large-vessel occlusion. However, in more than half of the treated patients, remaining small vessel occlusions (e.g. due to clot fragmentation during the procedure) limit the benefit of this therapy. In current clinical routine, the detection of these small remaining vessel occlusions and the decision for further treatment by the operator is based on 2D projection images. Recently, a new imaging technique, with the possibility to acquire whole brain 3D time-resolved perfusion directly in the operating room was technically made possible.  This perfusion technique allows evaluating brain reperfusion during acute interventional management of stroke patients, with many clinical implications. The presentation will cover an introduction to this new imaging technique, first results from a multicenter trial and the progress of implementation in the Val de Loire region.
