Door to groin puncture time is one of the determinants of clinical outcome in patients treated with endovascular thrombectomy (EVT). We have recently initiated a protocol, direct transfer to angiographic site, for patients transferred from outside hospitals. In this retrospective study, we investigated whether our new protocol had succeeded in shortening the door to groin puncture time. Data on consecutive patients with an occlusion at internal carotid artery or middle cerebral artery treated with EVT transferred from outside hospital between July 2012 and December 2018 were studied. Good outcome was defined as modified Rankin Scale score (mRS) ≤1 at 3 months. Forty (46%) patients were directly transferred to angiographic suite, 27 (19%) were indirectly transferred after CT, and 20 (23%) were after MRI. Onset to admission time was similar among the 3 groups (P = 0.711), while door to groin puncture time was significantly shorter in patients directly transferred to angiographic suite compared to those after CT as well as MRI (median 22 [25%-75%, 16-31] minutes vs. 31 [27-40], vs. 84 [58-124], P < 0.001). The rates of reperfusion with ≥ Thrombolysis in Cerebral Infarction 2b were similar among the 3 groups (88% vs. 85% vs. 90%, P = 0.886). The incidences of symptomatic intracerebral hemorrhage were also similar as 8% vs. 4% vs. 5% (P = 0.796). At 3 months after stroke, 16 (40%) patients in the 11 (41%) in those after CT, and 9 (45%) in those after MRI had the good outcome (P = 0.931). Direct transfer to angiography suite can shorten the onset to groin puncture time with safety.
