Abstract
BACKGROUND Dual-layer stents have fallen into disrepute after several studies reported high rates of in-stent occlusions in acute stroke treatments. The CGuard stent is a new-generation hybrid dual-layer stent that has been designed to provide less thrombogenicity and to prevent peri- and postinterventional emboli. The aim of the study is to evaluate the safety and efficacy of the CGuard stent for the acute treatment of occlusion or high-grade stenosis of the extracranial internal carotid artery (ICA) in patients with acute ischemic stroke (AIS) with and without concomitant intracranial large vessel occlusion (LVO). METHODS All patients who underwent emergent carotid artery stenting (CAS) with the CGuard stent were identified and analyzed from the stroke registries from four tertiary German stroke centers. Clinical, procedural, and imaging data were evaluated. Stent patency within 72 h, intracranial hemorrhage, and modified Rankin score (mRS) at discharge were the safety and efficacy end points. RESULTS Overall, ninety-six patients were included (mean age 70.2 ± 11.8, 66 males (68.8%), median NIHSS score at admission 11 (7-17), IV lysis: n = 44 (45.8%)). Stent placement was successful in all patients. Eighty-three (86.4%) patients had tandem occlusions. In-stent occlusion occurred in 5 patients (5.2%) and 3 patients developed early in-stent stenosis (3.1%). Median mRS at discharge was 2 (1-4). CONCLUSION In this multicenter study, the use of the dual-layer CGuard stent for emergent CAS, particularly in tandem occlusions, was safe and resulted in low rates of in-stent occlusions.

Predictors of symptomatic intracerebral hemorrhage after endovascular treatment for acute ischemic stroke due to tandem lesion in anterior circulation. J Stroke Cerebrovasc Dis 2024; 33:107852. [PMID: 38986970 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 07/03/2024] [Accepted: 07/08/2024] [Indexed: 07/12/2024] Open
Abstract
BACKGROUND Endovascular treatment (EVT) of tandem lesion (TL) in the anterior circulation acute ischemic stroke (IS) usually requires periprocedural antithrombotic treatment and early initiation of dual antiplatelet therapy (DAPT) after carotid stenting. However, it may contribute to an occurrence of symptomatic intracerebral hemorrhage (SICH) in some cases. We investigated factors influencing the SICH occurrence and assessed the possible predictors of SICH after EVT. METHODS IS patients with TL in the anterior circulation treated with EVT were enrolled in the multicenter retrospective ASCENT study. A good three-month clinical outcome was scored as 0-2 points in modified Rankin Scale (mRS) and recanalization using the TICI scale. SICH was assessed using the SITS-MOST criteria. Logistic regression analysis was used for the assessment of possible predictors of SICH with adjustment for potential confounders. RESULTS In total, 300 (68.7 % males, mean age 67.3 ± 10.2 years) patients with median of admission NIHSS 17 were analyzed. Recanalization (TICI 2b-3) was achieved in 290 (96.7 %) patients and 176 (58.7 %) had mRS 0-2. SICH occurred in 25 (8.3 %) patients. Patients with SICH did not differ from those without SICH in the rate of periprocedural antithrombotic treatment (64 vs. 57.5 %, p = 0.526) and in the rate of DAPT started within the first 12 h after EVT (20 vs. 42.2 %, p = 0.087). After adjustment, admission NIHSS and admission glycemia were found as the only predictors of SICH after EVT. CONCLUSION Admission NIHSS and glycemia were found as the only predictors of SICH after EVT for TL. No associations between periprocedural antithrombotic treatment, early start of DAPT after EVT and SICH occurrence were found.

Abstract
PURPOSE Double-layer design carotid stents have been cast in a negative light since several investigations reported high rates of in-stent occlusions, at least in the acute setting of tandem occlusions. CGuard is a new generation double-layered stent that was designed to prevent periinterventional embolic events. The aim of this study was to analyze the safety and efficacy of the CGuard in emergent CAS and for the acute treatment of tandem occlusions in comparison with the single-layer Carotid Wallstent (CWS) system. METHODS All patients who underwent CAS with CGuard or CWS after intracranial mechanical thrombectomy (MT) between 11/2018 and 12/2022 were identified from our local thrombectomy registry. Clinical, interventional and neuroimaging data were analyzed. Patency of the stent was assessed within 72 h. Intracranial hemorrhage and modified Rankin score (mRS) at discharge were the main endpoints. RESULTS In total, 86 stent procedures in 86 patients were included (CWS: 44, CGuard: 42). CGuard had a lower, but not statistically significant rate (p = 0.431) of in-stent occlusions (n = 2, 4.8%) when compared to the CWS (n = 4, 9.1%). Significant in-stent stenosis was found in one case in each group. There was no statistically significant difference in functional outcome at discharge between the two groups with a median mRS for CGuard of 2 (IQR:1-5) vs. CWS 3 (IQR:2-4). CONCLUSION In our series, the rate of in-stent occlusions after emergent CAS was lower with the dual-layer CGuard when compared to the monolayer CWS. Further data are needed to evaluate the potential benefit of the design in more detail.

Abstract
BACKGROUND Endovascular treatment (EVT) has been demonstrated to be effective for patients with tandem occlusion. The efficacy and safety of intravenous thrombolysis before EVT in patients with tandem occlusion remain debatable. METHODS AND RESULTS We conducted a systematic review and meta-analysis with PubMed, EMBASE, and the Cochrane Library from inception to September 2023. The primary outcome was functional independence, defined as a modified Rankin Scale score of 0 to 2 at 90 days. The secondary outcomes included the successful recanalization rate, symptomatic intracerebral hemorrhage, and mortality at 90 days. In total, 9 studies with 1838 enrolled participants were identified. Our results showed that, compared with treatment with EVT alone, intravenous thrombolysis before EVT was associated with a greater proportion of functional independence at 90 days (odds ratio [OR], 1.39 [95% CI, 1.14-1.69]; P=0.001), a greater rate of successful recanalization (OR, 1.45 [95% CI, 1.11-1.89]; P=0.007) and decreased mortality (OR, 0.68 [95% CI, 0.50-0.93]; P=0.02). Furthermore, there was no significant difference in symptomatic intracerebral hemorrhage between the intravenous thrombolysis plus EVT group and the EVT alone group (OR, 1.16 [95% CI, 0.79-1.70]; P=0.45). CONCLUSIONS In patients with acute ischemic stroke and tandem occlusion, intravenous thrombolysis before EVT was associated with a greater rate of favorable functional outcomes and successful recanalization and a lower mortality rate without an increased risk of symptomatic intracerebral hemorrhage compared with patients receiving EVT alone.

Abstract
BACKGROUND Although a benefit from mechanical thrombectomy has been proven, the best treatment strategy for tandem occlusions (TOs) remains unclear. We conducted a survey that aimed to investigate the trends of pharmacological strategy in the setting of emergent carotid stenting for TOs in the Italian neuro-endovascular community. METHODS We administered a 13-multiple choice-questions survey to the Chiefs of the centers participating to the Italian Registry of Endovascular Thrombectomy in Acute Stroke (IRETAS), focused on the technical aspects and on the management of the antiplatelet therapy for emergent carotid tenting in TOs. An internal coherence control was performed by the coordinating investigator. RESULTS We obtained responses from 56/66 centers (84.8%). The main results of the survey showed that most of the center treat TOs using a retrograde approach, deploying a closed-cell stent. A single antiplatelet therapy is preferred at the moment of the deployment of the stent. CONCLUSIONS This survey showed that the current practice regarding the acute management of TOs, in particular the antiplatelet therapy, remains heterogeneous in the Italian neurovascular community. Specific evidences are urgently needed in order to achieve a consensus on the acute management of TOs.

Abstract
BACKGROUND The optimal management of tandem carotid lesions during endovascular thrombectomy (EVT) remains uncertain. The safety and efficacy of acute carotid artery stenting (aCAS) are debated, including safety concerns such as procedural complications and symptomatic intracerebral hemorrhage (sICH). We aimed to assess aCAS safety among EVT-treated patients using a large Canadian registry. METHODS We retrospectively analyzed the OPTIMISE registry and compared adult patients undergoing EVT and aCAS versus EVT only. The primary outcome was a composite of in-hospital death, long-term care facility destination at discharge, sICH, or any EVT-related procedural complications. Secondary outcomes included individual components of the primary outcome, EVT workflow times, final modified Thrombolysis in Cerebral Ischemia score and 90-day modified Rankin Scale score. Statistical significance was evaluated by a multivariate logistic regression model. RESULTS 4205 patients were included (330 with EVT-aCAS and 3875 with EVT-only). Both groups were similar with regard to baseline National Institutes of Health Stroke Scale score, Alberta Stroke Program Early CT Score and use of IV thrombolysis, but differed in age (EVT-aCAS group 67.2±12.1 years vs EVT-only group 71.3±14.1 years, P<0.001), proportion of women (28.2% vs 53.3%, P<0.001), and occlusion location (internal carotid artery terminus 44% vs 16%, P<0.001). The EVT-aCAS group showed a non-significant increase in odds of composite safety outcomes (adjusted OR 1.35 (95% CI 0.97 to 1.84), P=0.06) with a significantly higher proportion of procedural complications (10.0% vs 6.2%, P=0.002). CONCLUSION In a large national registry, EVT-aCAS was associated with a higher proportion of unfavorable safety outcomes, driven by more frequent procedural complications. Further research is needed to clarify the role of aCAS in tandem occlusion stroke.

Abstract
INTRODUCTION SOFIA catheter is a relatively new and recently FDA-approved aspiration catheter. This systematic review aims to investigate the safety and efficacy of SOFIA catheter for treatment of acute ischemic stroke (AIS) via ADAPT and Solumbra techniques. METHODS Search of all studies evaluating the SOFIA catheter for mechanical thrombectomy (MT) for treatment of AIS via ADAPT and Solumbra techniques from inception through 2020 on Pubmed, PMC, and Embase was performed. We analyzed the angiographic and clinical outcomes of both techniques with SOFIA catheter using the random-effects model. RESULTS From 18 studies, 1836 patients were included with 1365 receiving MT using ADAPT and 471 with solumbra technique. The mean age was 69.8 years and 51.1% of the patients were women. The rate of rescue therapy was 30%. The outcomes rates of ADAPT group were as follows; mFPE (59.3%), FPE (34.4%) final TICI 2b/3 (89.3%), procedural complications (8%), embolization to new territory (ENT) (2.3%), symptomatic ICH (5.4%), mean NIHSS (8.97), 90-day-mRS 0-2 (48.8%), and mortality (15.3%). The outcomes rates of Solumbra group were as follows; mFPE (60.5%), FPE (46.7%), final TICI 2b/3 (93%), procedural complications (6.4%), ENT (2%), symptomatic ICH (6%), mean NIHSS (7.59), mRS 0-2 (53.8%), and mortality (10.8%). ICA and posterior circulation strokes, and tandem lesions had worse outcomes (P < .005). MCA strokes were associated with better outcomes (P = .005). ASPECT scores' association with the clinical outcomes was found statistically significant. CONCLUSION SOFIA catheter is effective and safe to treat acute ischemic stroke regardless of applied MT technique.

Abstract
Background: Tandem lesions (TLs) cause up to 15-30% of all acute ischemic strokes (AISs). Endovascular treatment (EVT) is regarded as the first-line treatment; however, uncertainties remain with respect to the treatment and predictive outcome parameters. Here, we aimed to identify the clinical and demographic factors associated with functional short- and long-term outcomes in AIS patients with arteriosclerotic TLs undergoing EVT. Methods: This was a retrospective, mono-centric cohort study of 116 consecutive AIS patients with arteriosclerotic TLs who were endovascularly treated at a stroke center, with analysis of the relevant demographic, procedural, and imaging data. Results: A total of 116 patients were included in this study, with a median age of 72 years (IQR 63-80), 31% of whom were female (n = 36). The median NIHSS on admission was 14 (IQR 7-19), with a median ASPECT score of 9 (IQR 8-10) and median NASCET score of 99% (IQR 88-100%). A total of 52% of the patients received intravenous thrombolysis. In 77% (n = 89) of the patients, an antegrade EVT approach was used, with a good recanalization (mTICI2b3) achieved in 83% of patients (n = 96). Symptomatic intracerebral hemorrhage occurred in 12.7% (n = 15) of patients. A favorable outcome (mRS0-2) and mortality at 3 months were obtained for 40% (n = 47) and 28% of patients (n = 32), respectively. Age and NIHSS on admission were strongly associated with outcome parameters. Diabetes mellitus and previous neurological disorders were independently associated with long-term mortality (median 11 months, IQR 0-42). Conclusions: Younger age, lower stroke severity, and good recanalization were found to be independently associated with a favorable outcome. In contrast, older age, higher stroke severity, previous neurological disorders, and diabetes were correlated with mortality. The endovascular treatment of acute arteriosclerotic tandem lesions is feasible and relatively safe.

Abstract
BACKGROUND To better understand the influence of treatment strategies on outcomes for patients with tandem lesions undergoing acute internal carotid artery (ICA) stenting during endovascular treatment (EVT), this study compared clinical, technical, and safety outcomes in patients with acute ischemic stroke due to a large vessel occlusion (LVO) who underwent ICA stenting before versus after intracranial thrombectomy. METHODS This single-center retrospective cohort study included patients who underwent EVT due to a LVO and periprocedural ICA stenting for significant ICA stenosis or occlusion between September 2020 and January 2023. Data were extracted from the Maastricht Stroke Quality Registry (MaSQ-Registry). Primary outcome was the modified Rankin Scale (mRS) at 3 months. Secondary outcomes included procedure times, number of total thrombectomy attempts, first-attempt excellent recanalization rates (extended Thrombolysis In Cerebral Infarction (eTICI) ≥ 2C after one thrombectomy attempt), and safety outcomes. RESULTS This study included 50 patients. Thirty-one patients (62%) underwent ICA stenting before intracranial thrombectomy. No significant differences between both groups were found regarding mRS, total procedure time, number of total thrombectomy attempts, first-attempt excellent recanalization, or complications. Time between groin puncture and recanalization (reperfusion time) was significantly longer in patients who had ICA stenting before intracranial thrombectomy versus after intracranial thrombectomy (45 min versus 28 min, P = 0.004). CONCLUSION ICA stenting after intracranial thrombectomy in patients with tandem lesions undergoing EVT did not lead to better patient outcomes compared to stenting before intracranial thrombectomy, despite shorter reperfusion times.

Abstract
BACKGROUND To differentiate between pseudo occlusion (PO) and true occlusion (TO) of internal carotid artery (ICA) is important in thrombectomy treatment planning for patients with acute ischemic stroke. Although delayed contrast filling has been differentiated carotid PO from TO, its application has been limited by the implementations of multiphasic computed tomography angiography. In this study, we hypothesized that carotid ring sign, which is readily acquired from single-phasic CTA, can sufficiently differentiate carotid TO from PO. METHODS One thousand four hundred and twenty patients with anterior circulation stroke receiving endovascular therapy were consecutively recruited through a hospital- and web-based registry. Two hundred patients with nonvisualization of the proximal ICA were included in the analysis after a retrospective screening. Diagnosis of PO or TO of the cervical segment of ICA was made based on digital subtraction angiography. Diagnostic performances of carotid ring sign on arterial-phasic CTA and delayed contrast filling on multiphasic computed tomography angiography were evaluated and compared. RESULTS One-hundred twelve patients had ICA PO and 88 had TO. Carotid ring sign was more common in patients with TO (70.5% versus 6.3%; P<0.001), whereas delayed contrast filling was more common in PO (94.9% versus 7.7%; P<0.001). The sensitivity and specificity of carotid ring sign in diagnosing carotid TO were 0.70 and 0.94, respectively, whereas sensitivity and specificity of delayed contrast filling was 0.95 and 0.92 in judging carotid PO. CONCLUSIONS Carotid ring sign is a potent imaging marker in diagnosing ICA TO. Carotid ring sign could be complementary to delayed contrast filling sign in differentiating TO from PO, in particular in centers with only single-phasic CTA.

Abstract
BACKGROUND Carotid tandem lesions ((TL) ⩾70% stenosis or occlusion) account for 15-20% of acute stroke with large vessel occlusion. AIMS We investigated the safety and efficacy of intravenous tenecteplase (0.25 mg/kg) versus intravenous alteplase (0.9 mg/kg) in patients with carotid TL. METHODS This is a substudy of the alteplase compared with the tenecteplase trial. Patients with ⩾70% stenosis of the extracranial internal carotid artery (ICA) and concomitant occlusion of the intracranial ICA, M1 or M2 segments of the middle cerebral artery on baseline computed tomography angiography (CTA) were included. Primary outcome was 90-day-modified Rankin Scale (mRS) 0-1. Secondary outcomes were mRS 0-2, mortality, and symptomatic ICH (sICH). Angiographic outcomes were successful recanalization (revised Arterial Occlusive Lesion (rAOL) 2b-3) on first and successful reperfusion (eTICI 2b-3) on final angiographic acquisitions. Multivariable mixed-effects logistic regression was performed. RESULTS Among 1577 alteplase versus tenecteplase randomized controlled trial (AcT) patients, 128 (18.8%) had carotid TL. Of these, 93 (72.7%) underwent intravenous thrombolysis plus endovascular thrombectomy (IVT + EVT), while 35 (27.3%) were treated with IVT alone. In the IVT + EVT group, tenecteplase was associated with higher odds of 90-day-mRS 0-1 (46.0% vs. 32.6%, adjusted OR (aOR) 3.21; 95% CI = 1.06-9.71) compared with alteplase. No statistically significant differences in rates of mRS 0-2 (aOR 1.53; 95% CI = 0.51-4.55), initial rAOL 2b-3 (16.3% vs. 28.6%), final eTICI 2b-3 (83.7% vs. 85.7%), and mortality (18.0% vs. 16.3%) were found. SICH only occurred in one patient. There were no differences in outcomes between thrombolytic agents in the IVT-only group. CONCLUSION In patients with carotid TL treated with EVT, intravenous tenecteplase may be associated with similar or better clinical outcomes, similar angiographic reperfusion rates, and safety outcomes as compared with alteplase.

Abstract
PURPOSE Vessel wall imaging (VWI) for carotid plaque is better for detecting unstable carotid plaque such as intraplaque hemorrhage (IPH), lipid-rich necrotic core (LRNC), and thin/ruptured fibrous cap. However, the role of VWI before carotid artery stenting (CAS) is unclear. Thus, this study aimed to determine the findings of symptomatic carotid stenosis before CAS on angiography and carotid VWI and to evaluate the imaging findings associated with post-procedural clinical events after CAS. MATERIALS AND METHODS This retrospective study included 173 consecutive patients who underwent carotid VWI, CAS, and post-procedural diffusion-weighted imaging (DWI) after CAS. Findings of unstable plaque on carotid VWI and unstable findings on angiography were analyzed. We also analyzed the incidence of post-procedural clinical events, any stroke, myocardial infarction (MI), and death within 30 days of CAS. RESULTS Of 173 patients, 101 (58.4%) had initial ischemic symptoms and positive findings on DWI. Symptomatic patients were significantly higher in patients with IPH than in patients without IPH (62.4% vs. 45.8%, P=0.031). Degree of stenosis, thrombus of the stenotic lesion, flow delay of internal carotid artery, and flow arrest by filter thrombus had significantly higher prevalence in the symptomatic group. Twenty patients (11.6%) had post-procedural clinical events such as any stroke, clinical symptoms, and/or MI. Hyperlipidemia and intraluminal thrombus on angiography were identified as significant factors influencing post-procedural events after CAS. CONCLUSION An intraluminal thrombus on angiography was identified as a significant factor influencing post-procedural clinical events after CAS.

Abstract
BACKGROUND The periprocedural antithrombotic regimen might affect the risk-benefit profile of emergent carotid artery stenting (eCAS) in patients with acute ischemic stroke (AIS) due to tandem lesions, especially after intravenous thrombolysis. We conducted a systematic review and meta-analysis to evaluate the safety and efficacy of antithrombotics following eCAS. METHODS We followed PRISMA guidelines and searched MEDLINE, Embase, and Scopus from January 1, 2004 to November 30, 2022 for studies evaluating eCAS in tandem occlusion. The primary endpoint was 90-day good functional outcome. Secondary outcomes were symptomatic intracerebral hemorrhage, in-stent thrombosis, delayed stent thrombosis, and successful recanalization. Meta-analysis of proportions and meta-analysis of odds ratios were implemented. RESULTS 34 studies with 1658 patients were included. We found that the use of no antiplatelets (noAPT), single antiplatelet (SAPT), dual antiplatelets (DAPT), or glycoprotein IIb/IIIa inhibitors (GPI) yielded similar rates of good functional outcomes, with a marginal benefit of GPI over SAPT (OR 1.88, 95% CI 1.05 to 3.35, Pheterogeneity=0.31). Sensitivity analysis and meta-regression excluded a significant impact of intravenous thrombolysis and Alberta Stroke Program Early CT Score (ASPECTS). We observed no increase in symptomatic intracerebral hemorrhage (sICH) with DAPT or GPI compared with noAPT or SAPT. We also found similar rates of delayed stent thrombosis across groups, with acute in-stent thrombosis showing marginal, non-significant benefits from GPI and DAPT over SAPT and noAPT. CONCLUSIONS In AIS due to tandem occlusion, the periprocedural antithrombotic regimen of eCAS seems to have a marginal effect on good functional outcome. Overall, high intensity antithrombotic therapy may provide a marginal benefit on good functional outcome and carotid stent patency without a significant increase in risk of sICH.

Abstract
OBJECTIVES The optimal treatment strategy for ischemic stroke in patients presenting with tandem occlusions of the internal carotid artery remains controversial. Several studies have demonstrated better clinical outcomes after eptifibatide, which is a short half-life antiplatelet agent. This retrospective analysis focused on the safety and efficacy of low-dose eptifibatide administration in stroke patients with tandem lesions. METHODS We evaluated the results of endovascular treatment in 148 stroke patients with tandem lesions. Patients in whom balloon angioplasty alone resulted in satisfactory cerebral flow did not receive eptifibatide (33 patients); others received this drug together with stent implantation (115 patients). Eptifibatide was given as an intravenous bolus of 180 μg/kg and then in a modified low dose of 1 μg/kg/min for 24 hours. RESULTS There were no statistically significant differences between both groups regarding 30-day mortality, frequency of thrombotic events, or hemorrhagic complications. An analysis of clinical status at 30-day follow-up revealed that the administration of eptifibatide was associated with a statistically significant better outcome: a higher rate of either no neurological symptoms or only mild symptoms (4 NIHSS points maximally). CONCLUSIONS The administration of eptifibatide in stroke patients presenting with tandem lesions is relatively safe. Moreover, treatment with this drug can improve clinical outcomes in these challenging patients.

Abstract
PURPOSE Endovascular treatment (EVT) of tandem lesion (TL) in anterior circulation (AC) acute ischemic stroke (AIS) represents still a clinical challenge. We aimed to evaluate selected factors related to EVT and assess other possible predictors of good clinical outcome besides the generally known ones. METHODS AIS patients with TL in AC treated with EVT were enrolled in the multicenter retrospective ASCENT study. A good three-month clinical outcome was scored as 0-2 points in modified Rankin Scale (mRS) and achieved recanalization using the TICI scale. Symptomatic intracerebral hemorrhage (SICH) was assessed using the SITS-MOST criteria. Logistic regression analysis was used for the assessment of possible predictors of mRS 0-2 with adjustment for potential confounders. RESULTS In total, 300 (68.7% males, mean age 67.3 ± 10.2 years) patients with median of admission NIHSS 17 were analyzed. Recanalization (TICI 2b-3) was achieved in 290 (96.7%) patients and 176 (58.7%) had mRS 0-2. Besides the age, admission NIHSS and SICH, admission glycemia (p = 0.005, OR: 0.884) the stent patency within the first 30 days after EVT (p = 0.0003, OR: 0.219), dual antiplatelet therapy (DAPT) started within 12 h after EVT (p < 0.0001, OR: 5.006) and statin therapy started within 24 h after stenting (p < 0.0001, OR: 5.558) were found as other predictors. CONCLUSION Admission glycemia, start of DAPT within 12 h and statin therapy within 24 h after EVT, and stent patency within the first 30 days after EVT were found as other predictors of good three-month clinical outcome in AIS patients treated with EVT for TL.

Abstract
RATIONALE In-stent reocclusion after endovascular therapy has a negative impact on outcomes in acute ischemic stroke (AIS) due to tandem lesions (TL). Optimal antiplatelet therapy approach in these patients to avoid in-stent reocclusion is yet to be elucidated. AIMS To assess efficacy and safety of intravenous tirofiban versus intravenous aspirin in patients undergoing MT plus carotid stenting in the setting of AIS due to TL. SAMPLE SIZE ESTIMATES Two hundred forty patients will be enrolled, 120 in every treatment arm. METHODS AND DESIGN A multicenter, prospective, randomized, controlled (aspirin group), assessor-blinded clinical trial will be conducted. Patients fulfilling the inclusion criteria will be randomized at MT onset to the experimental or control group (1:1). Intravenous aspirin will be administered at a 500-mg single dose and tirofiban at a 500-mcg bolus followed by a 200-mcg/h infusion during the first 24 h. All patients will be followed for up to 3 months. STUDY OUTCOMES Primary efficacy outcome will be the proportion of patients with carotid in-stent thrombosis within the first 24 h after MT. Primary safety outcome will be the rate of symptomatic intracranial hemorrhage. DISCUSSION This will be the first clinical trial to assess the best antiplatelet therapy to avoid in-stent thrombosis after MT in patients with TL. TRIAL REGISTRATION The trial is registered as NCT05225961. February, 7th, 2022.

Abstract
Approximately 20-30% of patients with acute ischemic stroke, caused by large intracranial vessel occlusion, have a tandem lesion, defined as simultaneous presence of high-grade stenosis or occlusion of the cervical internal carotid artery and thromboembolic occlusion of the intracranial terminal internal carotid artery or its branches, usually the middle cerebral artery. Patients with tandem lesions have usually worse outcomes than patients with single intracranial occlusions, and intravenous thrombolysis is less effective in these patients. Although endovascular thrombectomy is currently a cornerstone therapy in the management of acute ischemic stroke due to large vessel occlusion, the optimal management of extracranial carotid lesions in tandem occlusion remains controversial. Acute placement of a stent in the cervical carotid artery lesion is the most used therapeutic strategy compared with stented balloon angioplasty and thrombectomy alone without carotid artery revascularization; however, treatment strategies in these patients are often more complex than with single occlusion, so treatment decisions can change based on clinical and technical considerations. The aim of this review is to analyze the results of different studies and trials, investigating the periprocedural neurointerventional management of patients with tandem lesions and the safety, efficacy of the different technical strategies available as well as their impact on the clinical outcome in these patients, to strengthen current recommendations and thus optimize patient care.

Clin Neurol Neurosurg 2023; 234:108005. [PMID: 37837908 DOI: 10.1016/j.clineuro.2023.108005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 09/28/2023] [Accepted: 09/29/2023] [Indexed: 10/16/2023]
Abstract
BACKGROUND Current studies have concluded that MT (Mechanical Thrombectomy) is safe and effective for tandem lesions (TL). However, The benefit of bridging therapy for TL is controversial. OBJECTIVE To compare efficacy and safety between bridging therapy and direct thrombectomy of tandem lesions. METHOD We conducted a systematic review and meta-analysis of studies comparing bridging therapy versus direct thrombectomy among TL patients with regards to symptomatic intracerebral hemorrhage(sICH), Parenchymal hemorrhage (PH), 3-month mortality, modified Rankin Scale (mRS) score within 3 months, successful reperfusion, and excellent reperfusion. The meta-analysis of proportions was conducted with a common effects model. RESULT Five studies (n = 1198 patients) were identified for the systematic review. For safety outcomes, the bridging group had no significant difference in the rate of symptomatic intracranial hemorrhage (OR = 0.78, 95% CI = 0.49-1.25, P = 0.31) and the rate of PH (OR = 0.67, 95% CI = 0.39-1.13, P = 0.13) but significantly lower rate of 3-month mortality (OR = 0.53, 95% CI = 0.37-0.75, P = 0.0004) compared to the direct thrombectomy group. In terms of efficacy outcomes, the bridging therapy group had a significantly higher rate of 3- month good functional outcome (mRS 0-2) (OR = 1.76, 95% CI = 1.38-2.24, P < 0.00001) and successful recanalization (OR = 1.69, 95% CI = 1.27-2.25, P = 0.0003) but no significant difference in the rate of excellent recanalization(OR = 1.21, 95% CI = 0.91-1.59, P = 0.19) in patients with TL compared to direct thrombectomy group. CONCLUSION Bridging therapy is effective in improving the 3-month functional prognosis and increasing the rate of arterial recanalization without increasing the risk of intracranial hemorrhage in patients with TL compared to direct thrombectomy. A large multicentre clinical RCT is expected, as are advanced intravenous thrombolysis and endovascular thrombectomy techniques.

Abstract
OBJECTIVE Accurate differentiation between the intracranial and extracranial location of the acute internal carotid artery (ICA) occlusion is essential for guiding treatment decisions and mechanical thrombectomy planning. Multiphase Computed Tomography angiography (mCTA) appears to be superior to Single-phase Computed Tomography angiography (sCTA) in the evaluation of acute ICA occlusions. The main objective of our research is to study the accuracy of mCTA compared to sCTA in distinguishing isolated acute intracranial ICA occlusion from extracranial or tandem occlusion. METHODS Two observers independently analyzed sCTA and mCTA of patients with acute ICA occlusion at two different time points. The location of the occlusion was categorized as intracranial or extracranial for both imaging techniques and then compared with digital subtraction angiography (gold standard). Sensitivity and specificity rates for isolated intracranial ICA occlusion on sCTA and mCTA were calculated. Kappa statistics were used to assess interobserver agreement. RESULTS The sensitivity of sCTA and mCTA was 48.28% (28.36%-68.19%) and 79.31% (62.84%-95.78%) respectively for the diagnosis of isolated intracranial ICA occlusion, with an almost perfect interobserver agreement between both observers (p < 0.001). CONCLUSIONS Our research suggests that mCTA is more accurate than sCTA in distinguishing isolated intracranial occlusions from extracranial or tandem occlusions.

Abstract
BACKGROUND Acute ischemic stroke (AIS) due to anterior circulation tandem lesion (TL) remains a technical and clinical challenge for endovascular treatment (EVT). Conflicting results from observational studies and missing evidence from the randomized trials led us to report a recent real-world multicenter clinical experience and evaluate possible predictors of good outcome after EVT. METHODS We analyzed all AIS patients with TL enrolled in the prospective national study METRICS (Mechanical Thrombectomy Quality Indicators Study in Czech Stroke Centers). A good 3-month clinical outcome was scored as 0-2 points in modified Rankin Scale (mRS), achieved recanalization using the Thrombolysis In Cerebral Infarction (TICI) scale and symptomatic intracerebral hemorrhage (sICH) according to the Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST) criteria. RESULTS Of 1178 patients enrolled in METRICS, 194 (19.2%) (59.8% males, mean age 68.7±11.5 years) were treated for TL. They did not differ in mRS 0-2 (48.7% vs 46.7%; p=0.616), mortality (17.3% vs 22.7%; p=0.103) and sICH (4.7% vs 5.1%; p=0.809) from those with single occlusion (SO). More TL patients with prior intravenous thrombolysis (IVT) reached TICI 3 (70.3% vs 50.8%; p=0.012) and mRS 0-2 (55.4% vs 34.4%; p=0.007) than those without IVT. No difference was found in the rate of sICH (6.2% vs 1.6%; p=0.276). Multivariate logistic regression analysis showed prior IVT as a predictor of mRS 0-2 after adjustment for potential confounders (OR 3.818, 95% CI 1.614 to 9.030, p=0.002). CONCLUSION Patients with TL did not differ from those with SO in outcomes after EVT. TL patients with prior IVT had more complete recanalization and mRS 0-2 and IVT was found to be a predictor of good outcome after EVT.

Abstract
BACKGROUND While recent studies suggest a benefit of mechanical thrombectomy (MT) for the treatment of patients with isolated large vessel occlusions presenting after 24 hours from the last known well (LKW), the effect of MT for acute cervical tandem lesions (TLs) beyond 24 hours remains unknown. We aimed to evaluate the safety and effectiveness of MT beyond 24 hours of LKW in patients with TLs. METHODS We conducted a subanalysis study of patients with anterior circulation TL enrolled in a large, multicenter registry between January 2015 and December 2020. Patients were divided into 2 groups: MT beyond 24 hours versus MT 0-24-hour window. Outcomes of interest were functional independence (90-day modified Rankin scale 0-2), complete reperfusion (modified thrombolysis in cerebral infarction 3), delta NIH Stroke Scale (NIHSS), symptomatic intracranial hemorrhage (sICH), parenchymal hematoma 2 (PH2), in-hospital mortality, and 90-day mortality. Inverse probability of treatment weighting (IPTW) was used to balance the groups. RESULTS Overall, 589 participants were included, with 33 treated beyond 24 hours and 556 treated in the 0-24-hour window. After IPTW, we found no significant difference in the rates of achieving functional independence (odds ratio (OR) = 0.51; 95% confidence interval (CI) 0.22-1.16; p = 0.108), complete reperfusion (OR = 1.35; 95% CI 0.60-3.05; p = 0.464), sICH (OR = 1.96; 95% CI 0.37-10.5; p = 0.429), delta NIHSS (β = -3.61; 95% CI -8.11 to 0.87; p = 0.114), PH2 (OR = 1.46; 95% CI 0.29-7.27; p = 0.642), in-hospital mortality (OR = 1.74; 95% CI 0.52-5.86; p = 0.370), or 90-day mortality (OR = 1.37; 95% CI 0.49-3.83; p = 0.544) across both time windows. CONCLUSIONS Our results suggest that MT appears to benefit patients with TLs beyond 24 hours from LKW. Future prospective studies are warranted.

Accuracy of Computed Tomography Angiography for Diagnosing Extracranial Mural Lesions in Patients with Acute Internal Carotid Artery Occlusion: Correlation with Digital Subtraction Angiography. J Pers Med 2023; 13:1169. [PMID: 37511782 PMCID: PMC10381416 DOI: 10.3390/jpm13071169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/11/2023] [Accepted: 07/20/2023] [Indexed: 07/30/2023] Open
Abstract
Extracranial carotid mural lesions (CML), caused by atherosclerosis or dissection, are frequently observed in acute internal carotid artery (ICA) occlusion, often requiring angioplasty or stenting. This study aimed to assess the diagnostic accuracy of computed tomography angiography (CTA) in differentiating extracranial CML from thromboembolic etiology in acute ICA occlusion in patients eligible for endovascular treatment. Two neuroradiologists retrospectively studied patients with apparent extracranial ICA occlusion on CTA. Patients were divided into two groups: thromboembolism and CML, based on findings from CTA and digital subtraction angiography (DSA). CTA sensitivity and specificity were calculated using DSA as the gold standard. Occlusive patterns and cervical segment widening were evaluated for atherosclerosis, dissection, and thromboembolism etiologies. CTA had a sensitivity of 84.91% (74.32-95.49%) and a specificity of 95.12% (87.31-100%) in detecting extracranial CML. Atherosclerosis was the most common cause, distinguishable with high accuracy using CTA (p < 0.001). No significant differences were found in occlusive patterns between dissection and thromboembolism (p = 0.568). Cervical segment widening was only observed in dissection cases due to mural hematoma. Conclusions: CTA accurately differentiates extracranial CML from thromboembolic etiology in acute ICA occlusion. The pattern of the occlusion and the artery widening help to establish the location and the etiology of the occlusion.

World Neurosurg 2023; 175:e208-e217.

Abstract
OBJECTIVE Carotid artery stenting (CAS) is the established treatment strategy of the cervical internal carotid artery (cICA) stenosis, but its use for acute tandem lesions remains controversial. We investigated the clinical and procedural outcomes of management of cICA lesions and evaluated the risk factors for complications. METHODS Fifty patients who underwent acute mechanical thrombectomy for tandem lesion between January 2014 and June 2022 were included. Treatment of the cICA lesion was classified into the CAS group or the non-CAS group. The risk factors for postoperative ischemic events or symptomatic intracranial hemorrhage (sICH) were analyzed. RESULTS The CAS group included 36 patients (72%) and the non-CAS group 14 (28%). Postoperative complications were observed in 9 patients (18%). Thromboembolic complications occurred in 4 patients (29%) of the non-CAS group but in 1 patient (3%) of the CAS group. Severe calcification of the cICA (P = 0.04), non-CAS (P = 0.018), and more than 60% residual stenosis (P = 0.016) were significant risk factors associated with thromboembolic complications. sICH occurred in 4 patients (11%) of the CAS group but in none of the non-CAS group. More than 80% stenosis improvement was significantly associated with sICH (P = 0.049). Twenty-nine patients (58%) had a good clinical outcome at 90 days after onset. CONCLUSIONS Acute CAS is effective for the management for cICA tandem lesions during mechanical thrombectomy, but care not to overextend may be important to reduce the risk of sICH. Severe calcification of the cICA may increase the risk of postoperative thromboembolic complications using non-CAS treatment.

Safety and Efficacy of Tenecteplase and Alteplase in Patients With Tandem Lesion Stroke: A Post Hoc Analysis of the EXTEND-IA TNK Trials. Neurology 2023; 100:e1900-e1911. [PMID: 36878701 PMCID: PMC10159769 DOI: 10.1212/wnl.0000000000207138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 01/18/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND AND OBJECTIVES The safety and efficacy of tenecteplase (TNK) in patients with tandem lesion (TL) stroke is unknown. We performed a comparative analysis of TNK and alteplase in patients with TLs. METHODS We first compared the treatment effect of TNK and alteplase in patients with TLs using individual patient data from the EXTEND-IA TNK trials. We evaluated intracranial reperfusion at initial angiographic assessment and 90-day modified Rankin scale (mRS) with ordinal logistic and Firth regression models. Because 2 key outcomes, mortality and symptomatic intracranial hemorrhage (sICH), were few in number among those who received alteplase in the EXTEND-IA TNK trials, we generated pooled estimates for these outcomes by supplementing trial data with estimates of incidence obtained through a meta-analysis of studies identified in a systematic review. We then calculated unadjusted risk differences to compare the pooled estimates for those receiving alteplase with the incidence observed in the trial among those receiving TNK. RESULTS Seventy-one of 483 patients (15%) in the EXTEND-IA TNK trials possessed a TL. In patients with TLs, intracranial reperfusion was observed in 11/56 (20%) of TNK-treated patients vs 1/15 (7%) alteplase-treated patients (adjusted odds ratio 2.19; 95% CI 0.28-17.29). No significant difference in 90-day mRS was observed (adjusted common odds ratio 1.48; 95% CI 0.44-5.00). A pooled study-level proportion of alteplase-associated mortality and sICH was 0.14 (95% CI 0.08-0.21) and 0.09 (95% CI 0.04-0.16), respectively. Compared with a mortality rate of 0.09 (95% CI 0.03-0.20) and an sICH rate of 0.07 (95% CI 0.02-0.17) in TNK-treated patients, no significant difference was observed. DISCUSSION Functional outcomes, mortality, and sICH did not significantly differ between patients with TLs treated with TNK and those treated with alteplase. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that TNK is associated with similar rates of intracranial reperfusion, functional outcome, mortality, and sICH compared with alteplase in patients with acute stroke due to TLs. However, the CIs do not rule out clinically important differences. TRIAL REGISTRATION INFORMATION: clinicaltrials.gov/ct2/show/NCT02388061; clinicaltrials.gov/ct2/show/NCT03340493.

Functional and Safety Outcomes of Carotid Artery Stenting and Mechanical Thrombectomy for Large Vessel Occlusion Ischemic Stroke With Tandem Lesions. JAMA Netw Open 2023; 6:e230736. [PMID: 36857054 PMCID: PMC9978940 DOI: 10.1001/jamanetworkopen.2023.0736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 01/06/2023] [Indexed: 03/02/2023] Open
Abstract
Importance Approximately 10% to 20% of large vessel occlusion (LVO) strokes involve tandem lesions (TLs), defined as concomitant intracranial LVO and stenosis or occlusion of the cervical internal carotid artery. Mechanical thrombectomy (MT) may benefit patients with TLs; however, optimal management and procedural strategy of the cervical lesion remain unclear. Objective To evaluate the association of carotid artery stenting (CAS) vs no stenting and medical management with functional and safety outcomes among patients with TL-LVOs. Design, Setting, and Participants This cross-sectional study included consecutive patients with acute anterior circulation TLs admitted across 17 stroke centers in the US and Spain between January 1, 2015, and December 31, 2020. Data analysis was performed from August 2021 to February 2022. Inclusion criteria were age of 18 years or older, endovascular therapy for intracranial occlusion, and presence of extracranial internal carotid artery stenosis (>50%) demonstrated on pre-MT computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography. Exposures Patients with TLs were divided into CAS vs nonstenting groups. Main Outcomes and Measures Primary clinical and safety outcomes were 90-day functional independence measured by a modified Rankin Scale (mRS) score of 0 to 2 and symptomatic intracranial hemorrhage (sICH), respectively. Secondary outcomes were successful reperfusion (modified Thrombolysis in Cerebral Infarction score ≥2b), discharge mRS score, ordinal mRS score, and mortality at 90 days. Results Of 685 patients, 623 (mean [SD] age, 67 [12.2] years; 406 [65.2%] male) were included in the analysis, of whom 363 (58.4%) were in the CAS group and 260 (41.6%) were in the nonstenting group. The CAS group had a lower proportion of patients with atrial fibrillation (38 [10.6%] vs 49 [19.2%], P = .002), a higher proportion of preprocedural degree of cervical stenosis on digital subtraction angiography (90%-99%: 107 [32.2%] vs 42 [20.5%], P < .001) and atherosclerotic disease (296 [82.0%] vs 194 [74.6%], P = .003), a lower median (IQR) National Institutes of Health Stroke Scale score (15 [10-19] vs 17 [13-21], P < .001), and similar rates of intravenous thrombolysis and stroke time metrics when compared with the nonstenting group. After adjustment for confounders, the odds of favorable functional outcome (adjusted odds ratio [aOR], 1.67; 95% CI, 1.20-2.40; P = .007), favorable shift in mRS scores (aOR, 1.46; 95% CI, 1.02-2.10; P = .04), and successful reperfusion (aOR, 1.70; 95% CI, 1.02-3.60; P = .002) were significantly higher for the CAS group compared with the nonstenting group. Both groups had similar odds of sICH (aOR, 0.90; 95% CI, 0.46-2.40; P = .87) and 90-day mortality (aOR, 0.78; 95% CI, 0.50-1.20; P = .27). No heterogeneity was noted for 90-day functional outcome and sICH in prespecified subgroups. Conclusions and Relevance In this multicenter, international cross-sectional study, CAS of the cervical lesion during MT was associated with improvement in functional outcomes and reperfusion rates without an increased risk of sICH and mortality in patients with TLs.

Abstract
BACKGROUND Among tandem occlusions, atherosclerotic cervical internal carotid artery occlusion (ACICAO) can be technically challenging and associated with its unique complications. We evaluated our experience with endovascular treatment (EVT) of ACICAO in the setting of acute ischemic stroke. METHODS In total, 154 consecutive patients who underwent EVT for acute anterior circulation stroke at our institute were retrospectively reviewed. Patients with tandem ACICAO were analyzed in this study. Procedures, recanalization rates, complications, and prognoses were evaluated. RESULTS Ten patients (6%) of all 154 patients had ACICAO. In nine (90%) of the 10 patients, cervical lesions were successfully crossed and intervened upon. Four patients underwent stenting and five underwent angioplasty alone, followed by intracranial procedure. Eight patients (80%) achieved successful recanalization following mechanical thrombectomy for intracranial occlusion. However, one patient had massive subarachnoid hemorrhage during the procedure and another patient developed massive intracranial hemorrhage after EVT, both after stenting. Four of the five patients who initially underwent angioplasty alone subsequently underwent staged endarterectomy or stenting for residual stenosis on or after the next day. The single patient in whom the cervical lesion could not be crossed and another with reocclusion after EVT underwent a rescue bypass procedure due to persistent ischemic symptoms. After 90 days, four patients (40%) were functionally independent (modified Rankin scale score 0-2). CONCLUSIONS Our experience suggests that EVT for ACICAO is technically feasible; however, it involves the potential risk of several significant complications. To avoid serious hemorrhagic complications, cervical lesions may be better treated with angioplasty alone first.

Ni H, Yang T, Jia Z, Shi H, Liu S, Zhao L. Outcomes in acute ischemic stroke patients undergoing endovascular thrombectomy: Cervical internal carotid artery pseudo-occlusion vs. true occlusion. Front Neurol 2023; 13:1106358. [PMID: 36698876 PMCID: PMC9868848 DOI: 10.3389/fneur.2022.1106358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 12/19/2022] [Indexed: 01/12/2023] Open
Abstract
Background and purpose Pseudo-occlusion of the cervical internal carotid artery (cICA) refers to an absence of intraluminal contrast on computed tomography angiography (CTA), while the artery is patent on digital subtraction angiography during endovascular thrombectomy. We aimed to compare the outcomes between the cICA pseudo-occlusion and true occlusion after thrombectomy. Methods We retrospectively analyzed patients with apparent cICA occlusion on CTA who underwent thrombectomy between January 2016 and August 2021, and divided them into the pseudo-occlusion and true occlusion groups based on angiographic exploration. Recanalization failure was defined as a modified Thrombolysis in Cerebral Infarction score of 0-2a. Poor outcome was defined as a 90-day modified Rankin Scale score of 3-6. Propensity score matching was performed to compare the outcomes. Sensitivity analysis using multivariate-adjusted regression in the original cohort was conducted to test the robustness of the findings. Results Of the 146 patients included, 79 patients (54.1%) had cICA pseudo-occlusion and 67 patients (45.9%) had true occlusion. Following 1:1 propensity score-matched analysis, patients with pseudo-occlusion had an increased likelihood of recanalization failure (OR, 3.18; 95% CI, 1.06-9.59; P = 0.040) and poor outcome (OR, 2.80; 95% CI, 1.07-7.30; P = 0.035) compared with patients with true occlusion. Sensitivity analysis showed that cICA pseudo-occlusion remained independently associated with recanalization failure (OR, 2.55; 95% CI, 1.07-6.09; P = 0.036) and poor outcome (OR, 2.48; 95% CI, 1.08-5.67; P = 0.032). Conclusions Patients with cICA pseudo-occlusion on CTA treated with thrombectomy had an increased risk of reperfusion failure and poor outcome compared with true occlusion patients.

Abstract
Abstract
Background
Acute large vessel occlusion due to underlying intracranial atherosclerotic stenosis (ICAS-LVO) increases the difficulty of revascularization, resulting in frequent re-occlusion. The establishment of its pathogenesis before endovascular treatment (EVT) is beneficial for patients. We aimed at developing and validating a clinical prediction model for ICAS-LVO patients before EVT.
Methods
Patients with acute large vessel occlusion at Jining No. 1 People’s Hospital from January 2019 to September 2021 were retrospectively included as the training cohort. The 70 patients who met the inclusion and exclusion criteria were included in the validation cohort (October 2021 to May 2022). Demographics, onset form, medical history, digital subtraction angiography (DSA) imaging data, and laboratory test data were collected. Preprocedural parameters for the ICAS-LVO risk prediction model were established by stepwise logistic regression controlling for the confounding effects. Then, we constructed a nomogram model and evaluated its performance via the Hosmer-Lemeshow goodness-of-fit test, area under the ROC curve (AUC) analysis.
Results
The 231 acute LVO patients were included in the final analysis, 74 (32.3%) patients were ICAS-LVO. A preoperative diagnosis prediction model consisting of five predictors for ICAS-LVO, including fluctuating symptoms, NIHSS < 16, atrial fibrillation, tapered sign, and ASITN/SIR score ≥ 2. The model depicted an acceptable calibration (Hosmer-Lemeshow test, p = 0.451) and good discrimination (AUC, 0.941; 95% confidence interval, 0.910–0.971). The optimal cut-off value for the ICAS-LVO scale was 2 points, with 86.5% sensitivity, 91.1% specificity, and 90.5% accuracy. In the validation cohort, the discriminative ability was promising with an AUC value of 0.897, implying a good predictive performance.
Conclusion
The established ICAS-LVO scale, which is composed of five predictors: fluctuating symptoms, NIHSS < 16, atrial fibrillation, tapered sign, and ASITN/SIR score ≥ 2, has a good predictive value for ICAS-LVO in Chinese populations.

J Stroke Cerebrovasc Dis 2022; 31:106630. [PMID: 35816785 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 06/09/2022] [Accepted: 06/30/2022] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVES This study aims to evaluate whether the presence of an external carotid artery embolism accompanying internal carotid artery occlusion may contribute to identifying the etiology of internal carotid artery occlusion in the early period. MATERIAL AND METHODS The presence of external carotid artery embolism was evaluated in 117 patients who were adjudicated for internal carotid artery occlusion based on digital subtraction angiography images. RESULTS Embolus in the external carotid artery was detected in 8 (6.8%) of the 117 patients with internal carotid artery occlusion (7 (87.5%) patients were found to have tandem and 1 (12.5%) patient had carotid T occlusion). In all of these patients, the thrombus was of embolic origin. Evaluation of the etiology revealed cardioembolic etiology in 4 patients and dissection in 1 patient, and the cause could not be determined in the remaining 3 patients. Patients with external carotid artery embolism accompanying an internal carotid artery occlusion had significantly higher The National Institutes of Health Stroke Scale scores at admission and significantly lower recanalization success compared to those without external carotid artery embolism (p = 0.009, p = 0.01). In the comparison of prognosis, poorer prognosis was observed in those with external carotid artery embolism, although without a statistically significant difference (p = 0.07). CONCLUSIONS This study observed that the etiology was mostly embolic in patients with external carotid artery embolism accompanying an internal carotid artery occlusion, most of whom were found to have tandem embolic occlusion, and cardiac origin appeared to be the prominent etiology of stroke.

Abstract
BACKGROUND Acute cerebral artery occlusion is a common disease with high morbidity and mortality. At present, the commonly used mechanical thrombectomy schemes are mechanical thrombectomy and stent thrombectomy. However, the clinical differences between the two methods is not fully understood. The present study aimed to evaluate the clinical effectiveness of Solitaire AB stent thrombectomy for acute cerebral infarction (ACI). METHODS A retrospective study was carried out in 96 ACI patients admitted to our department from January 2017 to January 2020. According to the treatment they received, they were divided into group A (conventional microcatheter mechanical thrombectomy, n = 48) and group B (Solitaire AB stent thrombectomy, n = 48). All patients were followed up for 3 months. Their pre- and post-operative nerve function indices were compared between the 2 groups. The therapeutic effects were evaluated by thrombolysis in cerebral infarction scale system, Glasgow coma scale (GCS), National Institutes of Health Stroke Scale (NIHSS), and modified Rankin scale statistics. RESULTS Two groups of patients with NIHSS scores postoperative 3 and 30 days decreased significantly compared with preoperation. NIHSS score of group A 3 and 30 days postoperation was significantly higher than group B (P < .05). Two groups of patients with GCS scores postoperative 3 and 30 days increased significantly compared with preoperation. GCS score of group A 3 and 30 days postoperation was significantly lower than group B (P < .05). Group B with vascular recanalization ratio postoperative 30 days was higher than group A, however with no significant differences (P > .05). Moreover, group B with outcomes (modified Rankin scale score ≤2 points) postoperative 3 months was better than group A, however with no significant differences (P > .05). CONCLUSION Solitaire AB stent embolectomy shows similar efficacy as mechanical thrombectomy in the treatment of ACI patients.

Abstract
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.

Abstract
Acute ischemic stroke (AIS) is caused by blockage of an arterial blood vessel in the brain by a thrombus, which interrupts oxygen supply to the brain parenchyma. The goal of endovascular stroke treatment (mechanical thrombectomy) is to restore blood flow as quickly and completely as possible. There are numerous factors that influence endovascular treatment success. They can be broadly grouped into a) factors related to blood vessels, b) factors related to the thrombus, c) factors related to endovascular treatment technique and tools and d) operator-related factors. While blood vessel and tgthro thrombus-related factors are mostly non-modifiable in the acute setting, operator and technique-related factors can be modified, and extensive research is currently being done to investigate the complex interplay of all these variables, and to optimize the modifiable factors to the maximum possible extent. In this review, we will describe these factors and how they interact with each other in detail, and outline some of their practical implications. We will conclude with a short summary and outlook on future directions for optimizing endovascular treatment success.

Abstract
PURPOSE Tandem occlusive lesions are responsible for up to 20% of acute ischemic stroke cases and are associated with poor prognosis if complete recanalization cannot be achieved. Endovascular recanalization might be challenging due to difficulties in the safe passage of the occluded plaque at the origin of the internal carotid artery (ICA). The balloon-assisted tracking technique (BAT), where a partially deflated balloon is exposed out of the catheter tip to facilitate its passage through stenosed or spastic arterial segments was introduced by interventional cardiologists and the applicability of the technique has been recently proposed in the field of neurointervention as well. Here we describe our experience using the BAT technique in the endovascular recanalization of tandem occlusive lesions. METHODS Procedures were performed from June 2013 to December 2020 in a single center. Baseline clinical and imaging data, procedural and follow-up details and clinical outcomes were retrospectively collected. RESULTS In this study 107 patients, median age 66 years, median admission NIHSS 14 and median ASPECTS 8 were included. Successful recanalization of the ICA using the BAT technique was achieved in 100 (93%) and successful intracranial revascularization in 88 (82%) patients. There were no complications attributable to the BAT technique. Intraprocedural complications occurred in 9 (8%) patients. Emergent stenting was performed in 40 (37%) at the end of the procedure. Postprocedural adverse events (intracerebral hemorrhage [ICH], malignant infarction) occurred in 6 (5%) patients. Good clinical outcome at 3 months (modified Rankin scale [mRS] 0-2) was 54 (50%) and mortality 26 (24%). Delayed stent placement during follow-up occurred in 21 cases. CONCLUSION Application of BAT technique in tandem occlusions appears feasible, safe, and efficient. Further evaluation of this technique is awaited.

Abstract
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.

Abstract
Ostial common carotid artery (CCA) stenosis is rare, compared to extracranial internal carotid artery bifurcation lesions. In cases of a tandem lesion, the proximal lesion usually involves the extracranial internal carotid artery, and the ostial CCA is rarely implicated. A 69-year-old woman who underwent 3 months of antiplatelet therapy for asymptomatic, right ostial, severely calcified CCA stenosis presented with sudden onset left hemiparesis. Radiographic examination revealed an ostial CCA-intracranial artery tandem lesion. After intracranial revascularization using a clot retrieval stent, we performed the endovascular treatment with a balloon-mounted stent using an embolic protection device. This procedure may be superior to others because it is possible to achieve early intracranial revascularization and prevent distal embolism during the complete treatment of proximal lesions.

Abstract
OBJECTIVE Different etiologies of extracranial internal carotid artery steno-occlusive lesions (ECLs) in patients with acute ischemic stroke (AIS) and tandem occlusion (TO) have been pooled together in randomized trials. However, carotid atherosclerosis (CA) and carotid dissection (CD), the two most common ECL etiologies, are distinct nosological entities. The authors aimed to determine if ECL etiology has impacts on the endovascular management and outcome of patients with TO. METHODS A multicenter, retrospective study of prospectively collected data was conducted. AIS patients were included who had TO due to internal CA or CD and ipsilateral M1 middle cerebral artery occlusion and underwent endovascular treatment (EVT). Comparative analyses including demographic data, safety, successful recanalization rates, and clinical outcome were performed according to EVT and ECL etiology. RESULTS In total, 214 AIS patients with TOs were included (77.6% CA related, 22.4% CD related). Patients treated with a retrograde approach were more often functionally independent at 3 months than patients treated with an antegrade approach (OR 0.6, 95% CI 0.4-0.9). Patients with CD-related TOs achieved 90-day clinical independence more often than patients with CA-related TOs (OR 1.4, 95% CI 1.1-2.0). Emergency stenting use was associated with good 3-month clinical outcome only in patients with CA-related TOs (OR 1.4, 95% CI 1.1-2.1). Symptomatic intracranial hemorrhage (sICH) occurred in 10.7% of patients, without differences associated with ECL etiology. CONCLUSIONS ECL etiology impacts both EVT approach and clinical outcome in patients with TOs. Patients with CD-related TO achieved higher 3-month functional independence rates than patients with CA-related TOs. A retrograde approach can be desirable for both CA- and CD-related TOs, and emergency stenting is likely better justified in CA-related TOs.

Management and outcome of patients with acute ischemic stroke and tandem carotid occlusion in the ESCAPE-NA1 trial. J Neurointerv Surg 2021; 14:neurintsurg-2021-017474.

Abstract
BACKGROUND The optimal treatment and prognosis for stroke patients with tandem cervical carotid occlusion are unclear. We analyzed outcomes and treatment strategies of tandem occlusion patients in the ESCAPE-NA1 trial. METHODS ESCAPE-NA1 was a multicenter international randomized trial of nerinetide versus placebo in 1105 patients with acute ischemic stroke who underwent endovascular treatment. We defined tandem occlusions as complete occlusion of the cervical internal carotid artery (ICA) on catheter angiography, in addition to a proximal ipsilateral intracranial large vessel occlusion. Baseline characteristics and outcome parameters were compared between patients with tandem occlusions versus those without, and between patients with tandem occlusion who underwent ICA stenting versus those who did not. The influence of tandem occlusions on functional outcome was analyzed using multivariable regression modeling. RESULTS Among 115/1105 patients (10.4%) with tandem occlusions, 62 (53.9%) received stenting for the cervical ICA occlusion. Of these, 46 (74.2%) were stented after and 16 (25.8%) before the intracranial thrombectomy. A modified Rankin Score (mRS) of 0-2 at 90 days was achieved in 82/115 patients (71.3%) with tandem occlusions compared with 579/981 (59.5%) patients without tandem occlusions. Tandem occlusion did not impact functional outcome in the adjusted analysis (OR 1.5, 95% CI 0.95 to 2.4). Among the subgroup of patients with tandem occlusion, cervical carotid stenting was not associated with different outcomes compared with no stenting (mRS 0-2: 75.8% vs 66.0%, adjusted OR 2.0, 95% CI 0.8 to 5.1). CONCLUSIONS Tandem cervical carotid occlusion in patients with acute large vessel stroke did not lower the odds of good functional outcome in our study. Functional outcomes were similar irrespective of the management of the cervical ICA occlusion (stenting vs not stenting).

Endovascular therapy with or without intravenous thrombolysis in acute stroke with tandem occlusion. J Neurointerv Surg 2021; 14:314-320.

Abstract
BACKGROUND Endovascular 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. OBJECTIVE To compare EVT alone with EVT plus IVT in patients with acute ischemic stroke due to anterior circulation tandem occlusions. METHODS This 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. RESULTS Overall, 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. CONCLUSIONS Our 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.

Abstract
OBJECTIVE To investigate factors associated with poor clinical outcomes in patients with acute ischemic stroke undergoing endovascular therapy. METHODS A retrospective review of 265 patients with acute ischemic stroke treated in the First Hospital of Jilin University between January 1, 2016, and November 1, 2019, was performed. The primary outcome was the proportion of patients with a modified Rankin score of 0-2 at 90 days. Univariate and multivariate analyses were performed to assess potential clinical factors associated with a poor 90-day outcome. RESULTS The rates of successful revascularization, good prognosis, symptomatic intracranial hemorrhage, and mortality were 84.5%, 46.0%, 9.8%, and 12.8%, respectively. As per univariate analysis, age, diagnosis of atrial fibrillation, diagnosis of diabetes, high baseline glucose level, tandem occlusion, high National Institutes of Health Stroke Scale (NIHSS) score at admission, general anesthesia, number of passes, high NIHSS score on discharge, unsuccessful recanalization (modified treatment in cerebral ischemia score <2b), and development of symptomatic intracranial hemorrhage, hemorrhagic infarction, parenchymal hematoma, and subarachnoid hemorrhage were associated with poor prognosis. Tobacco use was positive in correlation with good prognosis in univariate analysis. Diabetes, tandem occlusion, high NIHSS score at admission, and general anesthesia were independent factors associated with a poor 90-day outcome in multivariate analysis. CONCLUSIONS Diabetes, tandem occlusion, high NIHSS score at admission, and general anesthesia were independent risk factors associated with a poor 90-day outcome and should be considered a reference by neurointerventionalists in guiding their clinical decision-making.

Abstract
OBJECTIVE To evaluate the results of endovascular treatment of patients with ischemic stroke caused by acute tandem occlusion of the internal carotid and middle cerebral arteries (ICA and MCA). MATERIAL AND METHODS Endovascular intervention was performed in 8 patients with tandem occlusion of ICA and MCA. The neurological deficit on admission was 17.4±5.6 NIHSS points and the average ASPECTS score was 9.5±0.8. The time from the onset of neurological symptoms to reperfusion was 224±68 min. Thrombolytic therapy was initiated before brain revascularization and continued intraoperatively in 4 out of 8 patients. ICA stenting after aspiration thrombectomy was required in 6 patients. Both antegrade (n=4) and retrograde (n=2) methods of brain revascularization were used. RESULTS The rate of detection of tandem lesion in patients with ischemic stroke who underwent endovascular treatment was 5.4%. Technical success in restoring blood flow in the ICA basin at extra-and intra-cranial levels (mTICI 2b/3) was achieved in 7 (87.5%) patients. Intracranial hemorrhagic complications that affected the outcome of the disease were clinically significant in 25% of patients (n=2). The mortality rate was 37.5% (n=3). A satisfactory clinical result (a deficit of 0-2 mRS scores) was achieved at discharge in one of 5 surviving patients. CONCLUSION Further studies of choosing the optimal surgical tactics for tandem occlusion of ICA and MCA, taking into account its effectiveness and safety, are need.

Abstract
BACKGROUND While mechanical thrombectomy (MT) is the standard of care for large vessel occlusion strokes, the optimal management of tandem occlusions (TO) remains uncertain. We aimed to determine the current practice patterns among stroke physicians involved in the treatment of TO during MT. METHODS We distributed an online survey to neurovascular practitioners (stroke neurologists, neurointerventionalists, neurosurgeons, and radiologists), members of professional societies. After 2 months the site was closed and data were extracted and analyzed. We divided respondents into acute stenting and delayed treatment groups and responses were compared between the two groups. RESULTS We received 220 responses from North America (48%), Latin America (28%), Asia (15%), Europe (5%), and Africa (4%). Preferred timing for cervical revascularization varied among respondents; 51% preferred treatment in a subsequent procedure during the same hospitalization whereas 39% preferred to treat during MT. Angioplasty and stenting (41%) was the preferred technique, followed by balloon angioplasty and local aspiration (38%). The risk of intracerebral hemorrhage was the most compelling reason for not stenting acutely (68%). There were no significant differences among practice characteristics and timing groups. Most practitioners (70%) agreed that there is equipoise regarding the optimal endovascular treatment of cervical lesions in TO; hence, 77% would participate in a randomized controlled trial. CONCLUSIONS The PICASSO survey demonstrates multiple areas of uncertainty regarding the medical and endovascular management of TOs. Experts acknowledged the need for further evidence and their willingness to participate in a randomized controlled trial to evaluate the best treatment for the cervical TO lesion.

Considerations for Antiplatelet Management of Carotid Stenting in the Setting of Mechanical Thrombectomy: A Delphi Consensus Statement. AJNR Am J Neuroradiol 2020; 41:2274-2279. [PMID: 33122218 DOI: 10.3174/ajnr.a6888] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 07/17/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE There are only few data and lack of consensus regarding antiplatelet management for carotid stent placement in the setting of endovascular stroke treatment. We aimed to develop a consensus-based algorithm for antiplatelet management in acute ischemic stroke patients undergoing endovascular treatment and simultaneous emergent carotid stent placement. MATERIALS AND METHODS We performed a literature search and a modified Delphi approach used Web-based questionnaires that were sent in several iterations to an international multidisciplinary panel of 19 neurointerventionalists from 7 countries. The first round included open-ended questions and formed the basis for subsequent rounds, in which closed-ended questions were used. Participants continuously received feedback on the results from previous rounds. Consensus was defined as agreement of ≥70% for binary questions and agreement of ≥50% for questions with >2 answer options. The results of the Delphi process were then summarized in a draft manuscript that was circulated among the panel members for feedback. RESULTS A total of 5 Delphi rounds were performed. Panel members preferred a single intravenous aspirin bolus or, in jurisdictions in which intravenous aspirin is not available, a glycoprotein IIb/IIIa receptor inhibitor as intraprocedural antiplatelet regimen and a combination therapy of oral aspirin and a P2Y12 inhibitor in the postprocedural period. There was no consensus on the role of platelet function testing in the postprocedural period. CONCLUSIONS More and better data on antiplatelet management for carotid stent placement in the setting of endovascular treatment are urgently needed. Panel members preferred intravenous aspirin or, alternatively, a glycoprotein IIb/IIIa receptor inhibitor as an intraprocedural antiplatelet agent, followed by a dual oral regimen of aspirin and a P2Y12 inhibitor in the postprocedural period.
