[Imaging-based indications for interventional treatment of stroke]

J Fiehler, G Thomalla
Der Nervenarzt 2015, 86 (10): 1200-8
The indications for mechanical thrombectomy are based on a proximal vessel occlusion in the absence of extensive ischemic damage in the corresponding dependent vascular territory. The maximum extent of early ischemic edema for which endovascular treatment is still useful is not clear from the studies. A benefit of mechanical thrombectomy can be safely assumed with an ASPECT score of 6-10, possibly also with lower scores. A more complex imaging with assessment of the status of collateral vessels or perfusion abnormality is scientifically interesting but usually not necessary for clinical decision-making for endovascular stroke treatment within the first 6 h after symptom onset.
