Tandem Occlusion

Background and Purpose: The efficacy of endovascular therapy in patients with acute ischemic stroke due to tandem occlusion is comparable to that for isolated intracranial occlusion in the anterior circulation. However, the optimal management of acute cervical internal carotid artery lesions is unknown, especially in the setting of carotid dissection, but emergency carotid artery stenting (CAS) is frequently considered. We investigated the safety and efficacy of emergency CAS for carotid dissection in patients with acute stroke with tandem occlusion in current clinical practice. Methods: We retrospectively analyzed a prospectively maintained database composed of 2 merged multicenter international observational real-world registries (Endovascular Treatment in Ischemic Stroke and Thrombectomy in Tandem Lesion). Data from endovascular therapy performed in the treatment of tandem occlusions related to acute cervical carotid dissection between January 2012 and January 2019 at 24 comprehensive stroke centers were analyzed. Results: The study assessed 136 patients with tandem occlusion due to dissection, including 65 (47.8%) treated with emergency CAS and 71 (52.2%) without. The overall rates of favorable outcome (90-day modified Rankin Scale score, 0–2) and successful reperfusion (modified Thrombolysis in Cerebral Infarction, 2b–3) were 58.0% (n=76 [95% CI, 49.6%–66.5%]) and 77.9% (n=106 [95% CI, 71.0%–85.0%]), respectively. In subgroup analyses, the rate of successful reperfusion (89.2% versus 67.6%; adjusted odds ratio, 2.24 [95% CI, 1.33–3.77]) was higher after CAS, whereas the 90-day favorable outcome (54.3% versus 61.4%; adjusted odds ratio, 0.84 [95% CI, 0.58–1.22]), symptomatic intracerebral hemorrhage (sICH; 10.8% versus 5.6%; adjusted odds ratio, 1.59 [95% CI, 0.79–3.17]), and 90-day mortality (8.0% versus 5.8%; adjusted odds ratio, 1.00 [95% CI, 0.48–2.09]) did not differ. In sensitivity analyses of patients with successful intracranial reperfusion, CAS was not associated with an improved clinical outcome. Conclusions: Emergency stenting of the dissected cervical carotid artery during endovascular therapy for tandem occlusions seems safe, whatever the quality of the intracranial reperfusion.

Background and Purpose: Endovascular therapy for tandem occlusion strokes of the anterior circulation is an effective and safe treatment. The best treatment approach for the cervical internal carotid artery (ICA) lesion is still unknown. In this study, we aimed to compare the functional and safety outcomes between different treatment approaches for the cervical ICA lesion during endovascular therapy for acute ischemic strokes due to tandem occlusion in current clinical practice. Methods: Individual patients’ data were pooled from the French prospective multicenter observational ETIS (Endovascular Treatment in Ischemic Stroke) and the international TITAN (Thrombectomy in Tandem Lesions) registries. TITAN enrolled patients from January 2012 to September 2016, and ETIS from January 2013 to July 2019. Patients with acute ischemic stroke due to anterior circulation tandem occlusion who were treated with endovascular therapy were included. Patients were divided based on the cervical ICA lesion treatment into stent and no-stent groups. Outcomes were compared between the two treatment groups using propensity score methods. Results: A total of 603 patients were included, of whom 341 were treated with acute cervical ICA stenting. In unadjusted analysis, the stent group had higher rate of favorable outcome (90-day modified Rankin Scale score, 0–2; 57% versus 45%) and excellent outcome (90-day modified Rankin Scale score, 0–1; 40% versus 27%) compared with the no-stent group. In inverse probability of treatment weighting propensity score–adjusted analyses, stent group had higher odds of favorable outcome (adjusted odds ratio, 1.09 [95% CI, 1.01–1.19]; P =0.036) and successful reperfusion (modified Thrombolysis in Cerebral Ischemia score, 2b-3; adjusted odds ratio, 1.19 [95% CI, 1.11–1.27]; P <0.001). However, stent group had higher odds of any intracerebral hemorrhage (adjusted odds ratio, 1.10 [95%, 1.02–1.19]; P =0.017) but not higher rate of symptomatic intracerebral hemorrhage or parenchymal hemorrhage type 2. Subgroup analysis demonstrated heterogeneity according to the lesion type (atherosclerosis versus dissection; P for heterogeneity, 0.01), and the benefit from acute carotid stenting was only observed for patients with atherosclerosis. Conclusions: Patients treated with acute cervical ICA stenting for tandem occlusion strokes had higher odds of 90-day favorable outcome, despite higher odds of intracerebral hemorrhage; however, most of the intracerebral hemorrhages were asymptomatic.

The Impact

Background and Purpose— Antiplatelet agents could be used in the setting of endovascular therapy for tandem occlusions to reduce the risk of de novo intracranial embolic migration, reocclusion of the extracranial internal carotid artery lesion, or in-stent thrombosis in case of carotid stent placement but have to be balanced with the intracerebral hemorrhagic transformation risk. In this study, we aim to investigate the impact of acute antiplatelet therapy administration on outcomes during endovascular therapy for anterior circulation tandem occlusions. Methods— This is a retrospective analysis of a collaborative pooled analysis of 11 prospective databases from the multicenter observational TITAN registry (Thrombectomy in Tandem Lesions). Patients were divided into groups based on the number of antiplatelet administered during endovascular therapy. The primary outcome was favorable outcome, defined as a modified Rankin Scale score of 0 to 2 at 90 days. Results— This study included a total of 369 patients; 145 (39.3%) did not receive any antiplatelet agent and 224 (60.7%) received at least 1 antiplatelet agent during the procedure. Rate of favorable outcome was nonsignificantly higher in patients treated with antiplatelet therapy (58.3%) compared with those treated without antiplatelet (46.0%; adjusted odds ratio, 1.38 [95% CI, 0.78–2.43]; P =0.26). Rate of 90-day mortality was significantly lower in patients treated with antiplatelet therapy (11.2% versus 18.7%; adjusted odds ratio, 0.47 [95% CI, 0.22–0.98]; P =0.042), without increasing the risk of any intracerebral hemorrhage. Successful reperfusion (modified Thrombolysis in Cerebral Ischemia score 2b-3) rate was significantly better in the antiplatelet therapy group (83.9% versus 71.0%; adjusted odds ratio, 1.89 [95% CI, 1.01–3.64]; P =0.045). Conclusions— Administration of antiplatelet therapy during endovascular therapy for anterior circulation tandem occlusions was safe and was associated with a lower 90-day mortality. Optimal antiplatelet therapy remains to be assessed, especially when emergent carotid artery stenting is performed. Further randomized controlled trials are needed.

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.

Introduction: Data related to the treatment of patients with acute ischemic stroke caused by carotid artery dissection is scarce. Methods: We retrospectively reviewed our interventional stroke database Sep 2010 - Jan 2014 to investigate the clinical and radiological characteristics of patients presenting with tandem cervical and intracranial occlusions due to cervical carotid dissection. Results: Out of 504 consecutive patients treated with endovascular therapy for acute ischemic stroke during the study period, 12 (2.5%) patients were observed to have cervical carotid artery dissection as the underlying etiology. Mean age was 56±13 years, 75% were male, 50% received IV t-PA, mean NIHSS was 20±5, 75% had CT ASPECTS≥7, and mean time from last known normal to groin puncture was 6±3 hours. There were 4 MCA M1, 1 MCA M2 and 7 ICA-T occlusions. Extracranial carotid stent was used in 58% and angioplasty in 8% of cases. In 33% of the cases, the carotid dissection was not stented due to the fear of hemorrhagic transformation in cases of IV thrombolysis (presumably increased risk if dual antithrombotics used). IA tPA was used in 41% of cases, while Merci in 16%, Penumbra in 58%, and stentretrivers in 50%. Intracranial TICI 2b-3 reperfusion was achieved in 91% of patients, with PH2 hemorrhage in 8% and mRS at 90 days in 45% of cases. Conclusions: Carotid dissections with associated intracranial occlusions are often refractory to IV tPA and present with a high stroke severity. These lesions are amenable to endovascular therapy resulting in high rates of reperfusion with an acceptable safety profile.

Symptomatic Intracerebral Hemorrhage

Background There are limited data on intravenous thrombolysis treatment in ischemic stroke patients with prestroke disability. Aim We aimed to evaluate safety and outcomes of intravenous thrombolysis treatment in stroke patients with prestroke disability. Methods We analyzed 88,094 patients treated with intravenous thrombolysis, recorded in the Safe Implementation of Treatments in Stroke (SITS) International Thrombolysis Register between January 2003 and December 2017, with available NIHSS data at stroke-onset and after 24 h. Of them, 4566 patients (5.2%) had prestroke disability, defined as a modified Rankin Scale score of 3–5. Safety outcome measures included Symptomatic Intracerebral Hemorrhage, any type of parenchymal hematoma on 24 h imaging scans irrespective of clinical symptoms, and death within seven days. Early outcome measures were 24-h NIHSS improvement (≥4 from baseline to 24 h). Results Patients with prestroke disability were older, had more severe strokes, and more comorbidities than patients without prestroke disability. When comparing patients with prestroke disability with patients without prestroke disability, there was however no significant increase in adjusted odds for symptomatic intracerebral hemorrhage (adjusted odds ratio 0.83 (95% CI 0.60–1.15) (absolute difference in proportion 1.17% vs. 1.27%)) or for parenchymal hemorrhage (adjusted odds ratio 0.96 (0.83–1.11) (7.51% vs. 6.34%)). The prestroke disability group had a significantly lower-adjusted odds ratio for a 24-h NIHSS improvement (adjusted odds ratio 0.79 (0.73–0.85) (45.95% vs. 48.45%)) and a higher adjusted odds ratio for seven-day mortality (aOR 1.40 (1.21–1.61) (10.40% vs. 4.93%)). Conclusions Intravenous thrombolysis in acute ischemic stroke patients with prestroke disability was not associated with an increased risk of symptomatic intracerebral hemorrhage or parenchymal hemorrhage. Prestroke disability was however associated with a higher risk of early mortality compared to patients without prestroke disability.

Background and Purpose— We aimed to compare functional and procedural outcomes of patients with acute ischemic stroke with none-to-minimal (modified Rankin Scale [mRS] score, 0–1) and moderate (mRS score, 2–3) prestroke disability treated with mechanical thrombectomy. Methods— Consecutive adult patients undergoing mechanical thrombectomy for an anterior circulation stroke were prospectively identified at 2 comprehensive stroke centers from 2012 to 2018. Procedural and 90-day functional outcomes were compared among patients with prestroke mRS scores 0 to 1 and 2 to 3 using χ 2 , logistic, and linear regression tests. Primary outcome and significant differences in secondary outcomes were adjusted for prespecified covariates. Results— Of 919 patients treated with mechanical thrombectomy, 761 were included and 259 (34%) patients had moderate prestroke disability. Ninety-day mRS score 0 to 1 or no worsening of prestroke mRS was observed in 36.7% and 26.7% of patients with no-to-minimal and moderate prestroke disability, respectively (odds ratio, 0.63 [0.45–0.88], P =0.008; adjusted odds ratio, 0.90 [0.60–1.35], P =0.6). No increase in the disability at 90 days was observed in 22.4% and 26.7%, respectively. Rate of symptomatic intracerebral hemorrhage (7.3% versus 6.2%, P =0.65), successful recanalization (86.7% versus 83.8%, P =0.33), and median length of hospital stay (5 versus 5 days, P =0.06) were not significantly different. Death by 90 days was higher in patients with moderate prestroke disability (14.3% versus 40.3%; odds ratio, 4.06 [2.82–5.86], P <0.001; adjusted odds ratio, 2.83 [1.84, 4.37], P <0.001). Conclusions— One-third of patients undergoing mechanical thrombectomy had a moderate prestroke disability. There was insufficient evidence that functional and procedural outcomes were different between patients with no-to-minimal and moderate prestroke disability. Patients with prestroke disability were more likely to die by 90 days.

Background and Purpose: The benefits of tPA (tissue-type plasminogen activator) in acute ischemic stroke are time-dependent. However, delivery of thrombolytic therapy rapidly after hospital arrival was initially occurring infrequently in hospitals in the United States, discrepant with national guidelines. Methods: We evaluated door-to-needle (DTN) times and clinical outcomes among patients with acute ischemic stroke receiving tPA before and after initiation of 2 successive nationwide quality improvement initiatives: Target: Stroke Phase I (2010–2013) and Target: Stroke Phase II (2014–2018) from 913 Get With The Guidelines-Stroke hospitals in the United States between April 2003 and September 2018. Results: Among 154 221 patients receiving tPA within 3 hours of stroke symptom onset (median age 72 years, 50.1% female), median DTN times decreased from 78 minutes (interquartile range, 60–98) preintervention, to 66 minutes (51–87) during Phase I, and 50 minutes (37–66) during Phase II ( P <0.001). Proportions of patients with DTN ≤60 minutes increased from 26.4% to 42.7% to 68.6% ( P <0.001). Proportions of patients with DTN ≤45 minutes increased from 10.1% to 17.7% to 41.4% ( P <0.001). By the end of the second intervention, 75.4% and 51.7% patients achieved 60-minute and 45-minute DTN goals. Compared with the preintervention period, hospitals during the second intervention period (2014–2018) achieved higher rates of tPA use (11.7% versus 5.6%; adjusted odds ratio, 2.43 [95% CI, 2.31–2.56]), lower in-hospital mortality (6.0% versus 10.0%; adjusted odds ratio, 0.69 [0.64–0.73]), fewer bleeding complication (3.4% versus 5.5%; adjusted odds ratio, 0.68 [0.62–0.74]), and higher rates of discharge to home (49.6% versus 35.7%; adjusted odds ratio, 1.43 [1.38–1.50]). Similar findings were found in sensitivity analyses of 185 501 patients receiving tPA within 4.5 hours of symptom onset. Conclusions: A nationwide quality improvement program for acute ischemic stroke was associated with substantial improvement in the timeliness of thrombolytic therapy start, increased thrombolytic treatment, and improved clinical outcomes.

Purpose: Endovascular treatment of atherosclerotic tandem occlusions in acute ischemic stroke (AIS) is a matter of debate. This article reports a single-center experience using an intermediate catheter with microballoon for treatment of tandem occlusions. Methods: A total of 151 AIS patients with large vessel occlusion received endovascular therapy and a consecutive series of patients (n = 26) who suffered from tandem cervical intracranial occlusions were treated using the Passing Extracranial Artery Occlusion by Intermediate Catheter with Expanding Microballoon (PEACE) technique. Intracranial recanalization was achieved by aspiration or stent retriever and then emergency stenting was performed for extracranial internal carotid artery (ICA) lesion. Demographic, clinical characteristics, procedural details of endovascular therapy, and prognosis outcome were assessed. The outcomes of tandem occlusion group were compared with isolated intracranial occlusion group (n = 122) and previous studies. Results: As compared to isolated intracranial occlusion groups, only a few patients suffered from atrial fibrillation (7.7% vs 38.5%, p<0.01) in tandem occlusions group. A larger proportion of patients (61.5% vs 29.5%) had tandem occlusions in which extracranial ICA occlusion was combined with intracranial terminus occlusion in ICA (p<0.01). 46.2% of tandem occlusions patients achieved intracranial recanalization by aspiration alone versus 15.6% in patients with isolated intracranial occlusion (p<0.01). In tandem occlusion patients treated with PEACE, 92.3% achieved successful reperfusion (thrombolysis in cerebral infarct [TICI] ≥2b). The median time from puncture to recanalization was 51 minutes (interquartile range [IQR], 41–66). 67.6% favorable functional prognosis (modified Rankin score [mRS], 0–2) was seen, with 11.5% mortality and 3.8% of symptomatic intracerebral hemorrhage (sICH) at 90 days. These outcomes are all consistent or better than previously reported studies performed for tandem occlusion. Conclusions: Endovascular therapy using the PEACE technique with intermediate catheter and lined expanding microballoon is safe, efficient, and fast in the treatment of atherosclerotic tandem occlusion patients.
