Mislocalization of the Culprit lesion by CT perfusion scan in patients with hyperacute stroke large vessel occlusion

초록

For hyperacute ischemic stroke due to large vessel occlusion(LVO),mechanical thrombectomy is the treatment option of choice. Usually, CT perfusion scans with angiography reveal the causative lesion ofLVO, which is the target of recanalization therapy. Sometimes, for various reasons, CT perfusion scans can mislead the locationof the target for treatment. Here we described two cases demonstratingmislocalization on CT scans.
