- Efficacy and safety of endovascular treatment in acute ischemic stroke due to cervical artery dissection: A 15-year consecutive case seriesPublication . Bernardo, F; Nannoni, S; Strambo, D; Puccinelli, F; Saliou, G; Michel, P, et al.BACKGROUND: Limited observational data are available on endovascular treatment in acute ischemic stroke due to cervical artery dissection. Three studies comparing endovascular treatment with standard medical therapy or intravenous thrombolysis in cervical artery dissection-related acute ischemic stroke did not demonstrate superiority of endovascular treatment. Efficacy and the choice of endovascular treatment technique in this setting remain to be established. AIMS: To assess the potential efficacy and safety of endovascular treatment compared to intravenous thrombolysis alone or to no revascularization treatment in our center. METHODS: We selected all consecutive patients with cervical artery dissection-related acute ischemic stroke and intracranial occlusion from the Acute STroke Registry and Analysis of Lausanne between 2003 and 2017. We compared clinical and neuroimaging data of patients treated by endovascular treatment versus patients receiving intravenous thrombolysis or patients without revascularization treatment. Safety analysis included symptomatic intracranial hemorrhage, major radiological hemorrhages (parenchymal hematoma 1, parenchymal hematoma 2, and subarachnoid hemorrhage) and mortality within seven days. We assessed favorable clinical outcome (modified Rankin Scale 0-2) at three months using a binary logistic regression model. RESULTS: Of the 109 patients included, 24 had endovascular treatment, 38 received intravenous thrombolysis alone, and 47 had no revascularization treatment. Endovascular treatment patients had a higher rate of recanalization at 24 h. Major radiological hemorrhages occurred more often in endovascular treatment patients (all with bridging therapy) than in patients without revascularization treatment (p = 0.026), with no differences in symptomatic intracranial hemorrhage or mortality within seven days. Favorable clinical outcome at three months did not differ between groups (endovascular treatment versus intravenous thrombolysis p = 0.407; endovascular treatment versus no revascularization treatment p = 0.580). CONCLUSIONS: In this single-center cohort of cervical artery dissection-related acute ischemic stroke with intracranial occlusion, endovascular treatment with prior intravenous thrombolysis may increase the risk of major radiological but not symptomatic intracranial hemorrhage. Despite the lack of clear superiority in our cohort, endovascular treatment should currently not be withheld in these patients.
- Intravenous thrombolysis in acute ischemic stroke due to intracranial artery dissection: a single-center case series and a review of literaturePublication . Bernardo, F; Nannoni, S; Strambo, D; Bartolini, B; Michel, P; Sirimarco, GEfficacy and safety of intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) due to intracranial artery dissection (IAD) are currently not established. We aimed to present a single-center experience on IAD-related AIS treated by IVT. We selected all consecutive patients with IAD-related AIS treated by IVT from a prospectively constructed single-center acute stroke registry from 2003 to 2017. We reviewed demographical, clinical and neuroimaging data and recorded hemorrhagic complications, mortality within 7 days and modified Rankin Scale at 3-months. Out of 181 AISs related to cervicocephalic dissections, 10 (5.5%) were due to IAD and five of these patients received IVT. Among these five patients, median age was 62 years; hypertension and dyslipidemia were the most frequent vascular risk factors. IAD locations were distal internal carotid artery, middle cerebral artery (M1), anterior cerebral artery (A2), and, in two cases, the basilar artery. All anterior circulation IADs were occlusive or subocclusive, while the two basilar artery IADs caused arterial stenosis. After IVT, there were no subarachnoid or symptomatic intracranial hemorrhages. One patient had an asymptomatic hemorrhagic infarct type 1. Two patients died within 7 days from ischemic mass effect. The other three patients had favorable clinical outcomes at 3-months. In this small single-center case series of IAD-related AIS, thrombolysis seemed relatively safe. However, IVT efficacy and the likelihood of arterial recanalization are still uncertain in this context. Further studies are needed to assess the safety and efficacy of IVT in these patients.
