Introduction: The benefit of intravenous thrombolysis (IVT) prior to endovascular treatment (EVT) in patients with acute ischemic stroke due to anterior circulation tandem occlusion is not well established. In this study, we aimed to investigate the effect of IVT on the outcome of EVT for anterior circulation tandem occlusions Methods: Individual data were pulled from the prospective TITAN and ETIS registries. Patients with anterior circulation tandem occlusion treated with EVT with and without cervical internal carotid artery ( c-ICA) stenting were included. Patents were divided into two groups (IVT+/IVT-) based on IVT treatment. Inverse Probability Treatment Weighting (IPTW) analysis were used to compare the outcomes between the two groups. Results: A total of 602 patients were included of whom 380 (62%) patients received IVT prior to EVT (IVT+). Mean age was 64 and 62 years in IVT+ and IVT - groups, respectively. Median NIHSS was 16 in both groups. Onset to imaging time was shorter in IVT+ group (median 103 vs. 140 minutes). In contrast, imaging to puncture time was longer in IVT+ group (median, 107 vs. 91 minutes). In IPTW analysis, IVT was associated with higher odds of favorable outcome (90-day modified Rankin Scale [mRS] 0-2), excellent outcome (mRS 0-1) and successful reperfusion (modified Treatment in Cerebral Ischemia [mTICI] 2b-3). IVT was also associated with lower odds of any intracranial hemorrhage but not with symptomatic hemorrhage or parenchymal hemorrhage. In secondary analysis of patients treated with cervical internal carotid artery stenting, IVT was associated with higher odds of favorable outcome, and lower odds of mortality. Conclusion: Up to our knowledge, this is the first study comparing EVT alone to EVT+IVT in anterior circulation tandem occlusion patients. IVT prior to EVT was associated with better functional outcome and higher odds of successful reperfusion.

BackgroundEndovascular therapy (EVT) is effective and safe in patients with tandem occlusion. The benefit of intravenous thrombolysis (IVT) prior to EVT in acute tandem occlusion is debatable.ObjectiveTo compare EVT alone with EVT plus IVT in patients with acute ischemic stroke due to anterior circulation tandem occlusions.MethodsThis is an individual patient pooled analysis of the Thrombectomy In TANdem lesions (TITAN) and Endovascular Treatment in Ischemic Stroke (ETIS) Registries. Patients were divided into two groups based on prior IVT treatment: (1) IVT+ group, which included patients who received IVT prior to EVT, (2) IVT− group, which included patients who did not receive IVT prior to EVT. Propensity score (inverse probability of treatment weighting (IPTW)) was used to reduce baseline between-group differences. The primary outcome was favorable outcome—that is, modified Rankin Scale (mRS) score 0 to 2 at 90 days.ResultsOverall, 602 consecutive patients with an acute stroke with tandem occlusion were included (380 and 222 in the bridging therapy and EVT alone groups, respectively). Onset to imaging time was shorter in the IVT+ group (median 103 vs 140 min). In contrast, imaging to puncture time was longer in the IVT+ group (median 107 vs 91 min). In IPTW analysis, the IVT+ group had higher odds of favorable outcome, excellent outcome (90-day mRS score 0–1), and successful reperfusion (modified Thrombolysis in Cerebral Infarction score 2b/3 at the end of EVT). There was no difference in the risk of significant hemorrhagic complications between groups. In secondary analysis of patients treated with acute cervical internal carotid artery stenting, bridging therapy was associated with higher odds of favorable outcome and lower odds of mortality at 90 days.ConclusionsOur results suggest that bridging therapy in patients with acute ischemic stroke due to anterior tandem occlusion is safe and may improve functional outcome, even in the setting of acute cervical internal carotid artery stenting during EVT.

OBJECTIVE Acute tandem occlusions of the cervical internal carotid artery and an intracranial large vessel present treatment challenges. Controversy exists regarding which lesion should be addressed first. The authors sought to evaluate the endovascular approach for revascularization of these lesions at Gates Vascular Institute. METHODS The authors performed a retrospective review of a prospectively maintained, single-institution database. They analyzed demographic, procedural, radiological, and clinical outcome data for patients who underwent endovascular treatment for tandem occlusions. A modified Rankin Scale (mRS) score ≤ 2 was defined as a favorable clinical outcome. RESULTS Forty-five patients were identified for inclusion in the study. The average age of these patients was 64 years; the mean National Institutes of Health Stroke Scale score at presentation was 14.4. Fifteen patients received intravenous thrombolysis before undergoing endovascular treatment. Thirty-seven (82%) of the 45 proximal cervical internal carotid artery occlusions were atherothrombotic in nature. Thirty-eight patients underwent a proximal-to-distal approach with carotid artery stenting first, followed by intracranial thrombectomy, whereas 7 patients underwent a distal-to-proximal approach (that is, intracranial thrombectomy was performed first). Thirty-seven (82%) procedures were completed with local anesthesia. For intracranial thrombectomy procedures, aspiration alone was used in 15 cases, stent retrieval alone was used in 5, and a combination of aspiration and stent-retriever thrombectomy was used in the remaining 25. The average time to revascularization was 81 minutes. Successful recanalization (thrombolysis in cerebral infarction Grade 2b/3) was achieved in 39 (87%) patients. Mean National Institutes of Health Stroke Scale scores were 9.3 immediately postprocedure (p < 0.05) (n = 31), 5.1 at discharge (p < 0.05) (n = 31), and 3.6 at 3 months (p < 0.05) (n = 30). There were 5 in-hospital deaths (11%); and 2 patients (4.4%) had symptomatic intracranial hemorrhage within 24 hours postprocedure. Favorable outcomes (mRS score ≤ 2) were achieved at 3 months in 22 (73.3%) of 30 patients available for follow-up, with an mRS score of 3 for 7 of 30 (23%) patients. CONCLUSIONS Tandem occlusions present treatment challenges, but high recanalization rates were possible in the present series using acute carotid artery stenting and mechanical thrombectomy concurrently. Proximal-to-distal and aspiration approaches were most commonly used because they were safe, efficacious, and feasible. Further study in the setting of a randomized controlled trial is needed to determine the best sequence for the treatment approach and the best technology for tandem occlusion.

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.

BackgroundIt is debated whether endovascular treatment is indicated for a symptomatic chronically occluded internal carotid artery (COICA).ObjectiveTo assess outcomes after endovascular treatment of COICA.MethodsWe performed a systematic search of three databases (PRISMA guidelines), including endovascular series of COICA. Outcomes were analyzed with random-effects models.ResultsWe included 13 studies and 528 endovascularly treated patients with COICA. Successful recanalization was 72.6% (347/528, 95% CI 65.4% to 79.9%, I2=68.9%). Complications were 18% (88/516, 95% CI 12.1% to 23.8%, I2=65%), with 5% (25/480, 95% CI 2% to 7%, I2=0%) of permanent events, and 9% (43/516, 95% CI 6% to 13%, I2=34%) of thromboembolisms. Treatment-related mortality was 2% (11/516, 95% CI 0.5% to 2.6%, I2=0%). Shorter duration of the occlusion was associated with higher recanalization: 80% (11/516, 95% CI 54% to 89%, I2=0%), 63% (33/52, 95% CI 49% to 76%, I2=0%), and 51% (18/35, 95% CI to 37% to 88%, I2=40%) recanalization rates for 1, 3, and >3 months occlusions, respectively. Complications were 6% (3/50, 95% CI 3% to 21%, I2=0%), 14% (4/27, 95% CI 5% to 26%, I2=0%), and 25% (13/47, 95% CI 10% to 30%, I2=0%) for 1, 3, and >3 months occlusions, respectively. Patient aged <70 years presented higher revascularization rates (OR=3.1, 95% CI 1.2 to 10, I2=0%, p=0.05). Successful reperfusion was higher (OR=5.7, 95% CI 1.2 to 26, I2=60%, p=0.02) and complications were lower (OR=0.2, 95% CI 0.6 to 0.8, I2=0%, p=0.03) for lesions limited to the cervical internal carotid artery compared with the petrocavernous segment. Successful recanalization significantly lowered the rate of thromboembolisms (OR=0.2, 95% CI 0.8 to 0.6, I2=0%, p=0.01) and mortality (OR=0.5, 95% CI 0.1 to 0.9, I2=0%, p=0.04), compared with conservative treatment.ConclusionsEndovascular treatment of COICA gives a 70% rate of successful recanalization, with 5% morbidity. Patients aged <70 years, lesions limited to the cervical internal carotid artery, and a shorter duration of the occlusion decreased the risk of complications. Successful recanalization of symptomatic lesions lowered by about 80% the likelihood of thromboembolisms, compared with medical management.

Механическая тромбэктомия в настоящее время является золотым стандартом в лечении острого ишемического инсульта при окклюзии крупных сосудов передней циркуляции мозгового кровообращения. Однако проблема лечения так называемой тандемной окклюзии - это одновременная окклюзия или критический стенозэкстракраниальной части внутренней сонной артерии (ВСА) в комбинации с окклюзией крупныхвнутримозговых сосудов передней циркуляции мозгового кровообращения в настоящее времяостается актуальной. В данной статье представлен клинический случай успешного лечения тандемной окклюзии внутренней сонной артерии и средней мозговой артерии путем проведения механической тромбэктомии с одномоментным стентированием внутренней сонной артерии. Однако для разработки единого стандарта лечения тандемных окклюзийнеобходимо проведение дальнейших исследований. Mechanical thrombectomy is currently the gold standard in the treatment of acute ischemic stroke with occlusion of large vessels of the anterior circulation of cerebral circulation. However, the problem of treating the so-called tandem occlusion is simultaneous occlusion or extracranial part of the internal carotid artery (ICA) critical stenosis in combination with occlusion of large intracerebral vessels of the anterior cerebral circulation currently remains relevant. This article presents a clinical case of successful treatment of tandem occlusion of the internal carotid artery and middle cerebral artery by mechanical thrombectomy with simultaneous ICA stenting. However, further research is needed to develop a unified standard for the tandem occlusions treatment.
