Background and Purpose

Intrahospital time delays significantly affect the neurological outcome of stroke patients with large-vessel occlusion. This study was conducted to determine whether a one-stop management can reduce intrahospital times of patients with acute large-vessel occlusion.


In this observational study, we report the first 30 consecutive stroke patients imaged and treated in the same room. As part of our protocol, we transported patients with a National Institutes of Health Stroke Scale score of ≥10 directly to the angio suite, bypassing multidetector computed tomography (CT). Preinterventional imaging consisted of noncontrast flat detector CT and flat detector CT angiography, acquired with an angiography system. Patients with large-vessel occlusions remained on the angio table and were treated with mechanical thrombectomy; patients with small artery occlusions were treated with intravenous thrombolysis, whereas patients with an intracranial hemorrhage and stroke mimics were treated as per guidelines. Door-to-groin puncture times were recorded and compared with our past results.


Thirty patients were transferred directly to our angio suite from June to December 2016. The time from symptom onset to admission was 105 minutes. Ischemic stroke was diagnosed in 22 of 30 (73%) patients, 4 of 30 (13.5%) had an intracranial hemorrhage, and 4 of 30 (13.5) were diagnosed with a Todd’s paresis. Time from admission to groin puncture was 20.5 minutes. Compared with 44 patients imaged with multidetector CT in the first 6 months of 2016, door-to-groin times were significantly reduced (54.5 minutes [95% confidence interval, 47-61] versus 20.5 minutes [95% confidence interval, 17-26]).


In this small series, a one-stop management protocol of selected stroke patients using latest generation flat detector CT led to a significant reduction of intrahospital times.
