RESUMO

Background@#and Purpose Despite the widespread adoption of mechanical thrombectomy (MT) for the treatment of large vessel occlusion stroke (LVOS) in the anterior circulation, the optimal strategy for the treatment tandem occlusion related to cervical internal carotid artery (ICA) dissection is still debated. This individual patient pooled analysis investigated the safety and efficacy of prior intravenous thrombolysis (IVT) in anterior circulation tandem occlusion related to cervical ICA dissection treated with MT. @*Methods@#We performed a retrospective analysis of two merged prospective multicenter international real-world observational registries: Endovascular Treatment in Ischemic Stroke (ETIS) and Thrombectomy In TANdem occlusions (TITAN) registries. Data from MT performed in the treatment of tandem LVOS related to cervical ICA dissection between January 2012 and December 2019 at 24 comprehensive stroke centers were analyzed. The primary endpoint was a favorable outcome defined as 90-day modified Rankin Scale (mRS) score of 0–2. @*Results@#The study included 144 patients with tandem occlusion LVOS due to cervical ICA dissection, of whom 94 (65.3%) received IVT before MT. Prior IVT was significantly associated with a better clinical outcome considering the mRS shift analysis (common odds ratio, 2.59; 95% confidence interval [CI], 1.35 to 4.93; P=0.004 for a 1-point improvement) and excellent outcome (90-day mRS 0–1) (adjusted odds ratio [aOR], 4.23; 95% CI, 1.60 to 11.18). IVT was also associated with a higher rate of intracranial successful reperfusion (83.0% vs. 64.0%; aOR, 2.70; 95% CI, 1.21 to 6.03) and a lower rate of symptomatic intracranial hemorrhage (4.3% vs. 14.8%; aOR, 0.21; 95% CI, 0.05 to 0.80). @*Conclusions@#Prior IVT before MT for the treatment of tandem occlusion related to cervical ICA dissection was safe and associated with an improved 90-day functional outcome.

RESUMO

BACKGROUND AND PURPOSE: Recent single-center series and meta-analyses suggest that mechanical thrombectomy (MT) without prior intravenous thrombolysis (IVT) might be equally effective to bridging therapy. We analyzed, within the Endovascular Treatment in Ischemic Stroke (ETIS) prospective observational registry, the angiographic and clinical outcomes after IVT+MT versus MT alone. METHODS: From December 2012 to December 2016, a total of 1,507 consecutive patients with a proximal arterial occlusion of the anterior circulation were treated by MT. Of these, 975 (64.7%) received prior IVT. Immediate angiographic and clinical outcomes at 90 days (modified Rankin Scale [mRS]) were compared between the two groups while checking for propensity score, matched-propensity score and by inverse probability of treatment weighting (IPTW) propensity score method. RESULTS: Favorable outcome (mRS 0 to 2) was more frequently achieved after IVT+MT (n=523, 53.6%) than after MT alone (n=222, 41.8%) with an unadjusted odds ratio (OR) for bridging therapy of 1.61 (95% confidence interval [CI], 1. 29 to 2.01). This difference remained not significant in matched-propensity score cohort (OR, 1.21; 95% CI, 0.90 to 1.63) although it remained according to adjusted propensity score (OR, 1.31; 95% CI, 1.02 to 1.68) and IPTW (OR, 1.37; 95% CI, 1.09 to 1.73) analyses. A significant difference was found in terms of excellent outcome (mRS 0 to 1) (adjusted OR, 1.63; 95% CI, 1.25 to 2.11) and successful reperfusion (adjusted OR, 1.58; 95% CI, 1.33 to 2.15). No differences in intracerebral hemorrhage or in allcause mortality within 90 days were found between groups. CONCLUSIONS: IVT prior to MT is associated with increased excellent outcome and successful reperfusion rates. These findings support the use of bridging therapy.

RESUMO

On page 271, in Table 1, the value ‘1115 (65??51)’ of subgroup ‘Imaging to groin puncture’ and column heading ‘SVS (??’ was input incorrectly. The correct value is ‘115 (65??51).’

RESUMO

BACKGROUND AND PURPOSE: In the Aspiration vs. Stent Retriever for Successful Revascularization (ASTER) trial, which evaluated contact aspiration (CA) versus stent retriever (SR) use as first-line technique, the impact of the susceptibility vessel sign (SVS) on magnetic resonance imaging (MRI) was studied to determine its influence on trial results. METHODS: We included patients having undergone CA or SR for M1 or M2 occlusions, who were screened by MRI with T2* gradient recalled echo. Occlusions were classified as SVS (+) or SVS (–) in each randomization arm. Modified thrombolysis in cerebral infarction (mTICI) 2b, 2c, or 3 revascularization rates were recorded and clinical outcomes assessed by the overall distribution of modified Rankin scale (mRS) at 90 days. RESULTS: Among the 202 patients included, 143 patients were SVS (+) (70.8%; 95% confidence interval [CI], 64.5% to 77.1%). Overall, there was no difference in angiographic and clinical outcomes according to SVS status. However, compared to SR, CA achieved a lower mTICI 2c/3 rate in SVS (+) patients (risk ratio [RR] for CA vs. SR, 0.60; 95% CI, 0.51 to 0.71) but not in SVS (–) (RR, 1.11; 95% CI, 0.69 to 1.77; P for interaction=0.018). A significant heterogeneity in favor of superiority of first-line SR strategy in SVS (+) patients was also found regarding the overall mRS distribution (common odds ratio for CA vs. SR, 0.40 vs. 1.32; 95% CI, 0.21 to 0.74 in SVS (+) vs. 95% CI, 0.51 to 3.35 in SVS (–); P for interaction=0.038). CONCLUSIONS: As a first line strategy, SR achieved higher recanalization rates and a more favourable clinical outcome at 3 months compared to CA when MRI shows SVS within the thrombus.
