Abstract T P37: Routine CT Angiography in Acute Stroke Does Not Delay Acute Stroke Care
Introduction: Vascular imaging is increasingly used for diagnosis of arterial occlusions in acute ischemic stroke. Hypothesis:We hypothesized that time intervals using a CTA based acute ischemic stroke protocol are not increased when compared to an earlier non-CTA based protocol. Methods: We evaluated a database of consecutive patients admitted to a Brazilian tertiary hospital with acute ischemic stroke from February 2009 to March 2014 and reviewed our stroke quality measures data to determine if the time required to obtain CTA prolonged door-to-neuroimaging, door to radiology report and door-to-needle times. Patients were categorized into: Group 1 (February 2009 to October 2013) (Non-contrast CT Scan based acute stroke protocol) and Group 2 (November 2013 to August 2014) (CTA based acute stroke protocol). Time intervals were compared between the two groups.Results: We evaluated 415 consecutive patients, 20 of whom (4.8%) had a CTA in the acute phase (Group 2). Patients in groups 1 and 2 had similar onset-to-door times (1.86 [0.75-3.58] versus 2.75 hours [1.0-8.49], p=0.09); door to neuroimaging times (27.6 [18.6-46.8] versus 37.8 minutes [23.4-46.2], p=0.28 ) and door to radiology report intervals (39 [27-60.6] versus 53.4 minutes[35.4-61.2], p=0.09). The frequency of treatment with recanalization therapies ( either intravenous thrombolysis or endovascular procedures) was similar between groups 1 (30%) and 2 (21%), p=0.33, as well as door to needle times (p=0.09). Conclusions: CTA based acute stroke care does not significantly delay time to neuroimaging or thrombolysis in routine clinical practice.
