Abstract
Background:
Safety and efficacy of recanalization treatments,
i.e.
intravenous thrombolysis (IVT) and/or mechanical thrombectomy (MT), have to be refined in pediatric stroke.
Methods:
The French KIDCLOT multisourcing nationwide retrospective study (NCT03887143) collected data of consecutive children aged >28 days and <18 years old with acute arterial ischemic stroke who had a recanalization treatment, during a 41 month-period.
Results:
68 patients, 44 boys (64.7%), median age at stroke onset 11.5 years old, were included. Pre-stroke mRS was 0 for 89.7%. Main stroke etiologies were cardio-embolic (30.9%), focal cerebral arteriopathy (FCA, 25%), cervical (carotid/vertebral) arteriopathy (13.2%), and thrombotic (11.8%). 70 pediatric procedures were recorded: IVT alone (n=31), MT alone (n=23), combined IVT and MT (n=14), and DSA without recanalization treatment (n=4). Median stroke onset to first recanalization treatment delay was shorter in adult stroke units than in pediatric wards (188 vs. 264 minutes respectively, p=0.0087). An early complication was reported for 6 procedures, including two significant intracranial hemorrhages. After MT, cardio-embolic stroke patients achieved good arterial recanalization more frequently than FCA patients (88.9% vs 33.3%). Although high initial severity markers (median NIHSScore=13.5, decreased consciousness in 52.2%, decompressive craniectomy in 17.1%), outcome was relatively good in the 65/68 survivors (median mRS=1 and PSOM=1.2 at 12 month-follow-up).
Conclusions:
This study provides encouraging safety data despite severe stroke presentations. It suggests potential ways to improve recanalization treatments efficacy in children: reducing management delays in pediatric wards and optimizing etiological orientation since the hyperacute phase, as cardio-embolic strokes seem to display a better recanalization rate profile.
