Renal Impairment Is Associated with Intracerebral Hemorrhage after Mechanical Thrombectomy in Vertebrobasilar Stroke

<b><i>Background and Purpose:</i></b> Renal dysfunction (RD) is overall associated with unfavorable functional outcome and higher risk of mortality after acute ischemic stroke. Associations between RD and outcome in patients with acute vertebrobasilar stroke treated with thrombectomy have not been evaluated so far. <b><i>Materials and Methods:</i></b> Consecutive patients with vertebrobasilar stroke treated with mechanical thrombectomy between October 2010 and July 2017 at our center were analyzed. RD was defined as glomerular filtration rate (GFR) < 60 mL/min/1.73 m<sup>2</sup> at admission. Endpoints were (I) poor clinic…
