BACKGROUND AND PURPOSE: Our aim was to study the effect of drainage of cortical veins, including the superficial middle cerebral vein (SMCV), vein of Trolard, and vein of Labbé on neurological outcomes after reperfusion therapy. METHODS: Consecutive ischemic stroke patients who underwent pretreatment computed tomographic perfusion and 24-hour computed tomographic perfusion or magnetic resonance perfusion after intravenous thrombolysis were included. We defined "absent filling of ipsilateral cortical vein" (eg, SMCV-) as no contrast filling of the vein across the whole venous phase on 4-dimensional computed tomographic angiography in the ischemic hemisphere. RESULTS: Of 228 patients, SMCV-, v..View full abstract
