Objective: To identify factors associated with early angiographic reperfusion improvement (EARI) following intra-arterial fibrinolytics (IAF) after failed or incomplete mechanical thrombectomy (MT). Methods: A subset of patients treated with MT and IAF rescue after incomplete reperfusion included in the INFINITY (INtra-arterial FIbriNolytics In ThrombectomY) multicenter observational registry was analyzed. Multivariable logistic regression was used to identify factors associated with EARI. Heterogeneity of the clinical effect of EARI on functional independence (defined as modified Rankin Score ≤2) was tested with interaction terms. Results: A total of 228 patients (median age: 72 years, 44.1% female) received IAF as rescue for failed or incomplete MT and had a post-fibrinolytic angiographic control run available (50.9% EARI). A cardioembolic stroke origin (adjusted odds ratio (aOR) 3.72, 95% confidence interval (CI) 1.39–10.0) and shorter groin puncture to IAF intervals (aOR 0.82, 95% CI 0.71–0.95 per 15-min delay) were associated with EARI, while pre-interventional thrombolysis showed no association (aOR 1.15, 95% CI 0.59–2.26). The clinical benefit of EARI after IAF seemed more pronounced in patients without or only minor early ischemic changes (Alberta Stroke Program Early Computed Tomography Score (ASPECTS) ≥9, aOR 4.00, 95% CI 1.37–11.61) and was absent in patients with moderate to severe ischemic changes (ASPECTS ≤8, aOR 0.94, 95% CI 0.27–3.27, p for interaction: 0.095). Conclusion: Early rescue and a cardioembolic stroke origin were associated with more frequent EARI after IAF. The clinical effect of EARI seemed reduced in patients with already established infarcts. If confirmed, these findings can help to inform patient selection and inclusion criteria for randomized-controlled trials evaluating IAF as rescue after MT.

Introduction: Recently, five published major randomized controlled clinical trials have demonstrated that timely mechanical thrombectomy (MT) of acute ischemic strokes (AIS) with emergent large vessel occlusion (ELVO) is safe and improves functional outcomes. However, data evaluating the efficacy and safety of MT in ELVO patients with concomitant cervical internal carotid artery (cICA) occlusion is limited. The purpose of this study is to evaluate efficacy and safety of MT in ELVO patients with concomitant cICA occlusion Methods: We prospectively analyzed consecutive AIS patients with anterior circulation ELVO who underwent stent-retriever or primary aspiration thrombectomy at two tertiary stroke centers. Outcome measures in our study were 3-month mortality and modified ranking scale (mRS), as well as symptomatic intracranial hemorrhage (sICH). Safety and efficacy outcomes were compared between ELVO patients with and without concomitant cICA occlusion. Results: A total of 137 AIS patients had anterior circulation ELVO and underwent MT (age 63 ± 14, 49% male, median NIHSS 17, IQR [13-20]). ELVO patients with concomitant cICA occlusion (n=19) did not differ in terms of rates of sICH (0% versus 11%, p=0.21), complete recanalization (68 % versus 68%, p=1.00), onset to groin puncture time (minutes [IQR] 268 [211-379] versus 225 [165-312], p=0.47), 3-month mortality (35% versus 26 %, p=0.55), and mRS of 0-2 at 3 months (41% versus 45%, p=0.80) when compared with ELVO patients without concomitant cICA occlusion (n=118). Admission NIHSS was higher among ELVO patients with concomitant cICA occlusion (median [IQR], 18 [15-22] versus 16 [12-19], p=0.01), and they tended to have higher groin puncture to recanalization time (minutes [IQR] 74 [42-97] versus 49 [38-78], p=0.09). The ordinal shift analysis did not show any difference in favorable outcomes in two groups in unadjusted analyses or after adjustment for admission NIHSS and groin to recanalization time (common OR=0.78 [95% CI: 0.27-2.29, p=0.66]). Angioplasty was performed in 11 of 19 ELVO patients with concomitant cICA occlusion. Three patients required stent placement. Discussion: Our study indicates that MT can be performed safely and effectively in ELVO patients with concomitant cICA occlusion.

BackgroundThe Advanced Thrombectomy System (ANCD) provides a new funnel component designed to reduce clot fragmentation and facilitate retrieval in patients with stroke by locally restricting flow, allowing distal aspiration in combination with a stent retriever (SR).ObjectiveTo evaluate the preclinical efficacy and safety of the ANCD in a swine clot model.MethodsSoft and firm clots were implanted in the lingual and cervical arteries of 11 swine to obtain Thrombolysis in Cerebral Infarction (TICI) 0 blood flow. Mechanical thrombectomy was performed with either a balloon guide catheter+Solitaire 2 stent retriever (BGC+SR, n=13) or ANCD+SR (n=13). TICI flow was evaluated and successful revascularization was defined as TICI 3 (normal perfusion). To characterize safety, a total of 3 passes were performed in each vessel independent of recanalization. Tissues were explanted for histopathological analysis after 3 and 30 days, respectively.ResultsFirst pass reperfusion rates were ANCD+SR: 69% and BGC+SR: 46%. Reperfusion increased after the third pass in both groups (ANCD+SR: 100%, vs BGC+SR: 77%). Recanalization was achieved after an average of 1.4 and 1.9 passes in ANCD+SR and BGC+SR (p=0.095), respectively. Vessel injury was comparable in both groups; endothelial loss at 3 days was the most common injury seen (ANCD+SR: 1.78±1.22; BGC+SR: 2.03±1.20; p=0.73), while other histopathological markers were absent or minimal. Tissues downstream from targeted vessels also showed absence or minimal lesions across both groups.ConclusionsResults in a swine clot model support the high efficacy of the ANCD+SR without causing clinically significant vessel injury potentially related to the new funnel component.
