Guide Catheter

In mechanical endovascular thrombectomy (MET) for acute basilar artery occlusion (ABAO) in the elderly, navigating a guide catheter via the femoral artery may be difficult due to the approach route’s significant tortuosity. To resolve this problem, we have been performing a technique that uses a direct brachial approach (DiBA) with a large-bore aspiration catheter. We reported our preliminary clinical experience with this technique. MET for ABAO using the DiBA technique was performed on 4 consecutive patients between August 2017 and December 2018. In all patients, thrombolysis in cerebral infarction 2B or 3 recanalization was achieved, but the modified Rankin Scale at 90 days was ≥4. There were no technical difficulties or complications with this technique. The DiBA technique is an effective and feasible approach in MET for ABAO. Although excellent clinical outcomes could not be achieved, the angiographic outcomes were excellent with no technical complications. This approach can be an alternative to the femoral artery approach, particularly for tortuous arteries in the elderly.

Background and Purpose— The posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) quantifies the extent of early ischemic changes in the posterior circulation with a 10-point grading system. We hypothesized that pc-ASPECTS applied to CT angiography source images predicts functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). Methods— BASICS was a prospective, observational registry of consecutive patients with acute symptomatic basilar artery occlusion. Functional outcome was assessed at 1 month. We applied pc-ASPECTS to CT angiography source images of patients with CT angiography for confirmation of basilar artery occlusion. We calculated unadjusted and adjusted risk ratios (RRs) of pc-ASPECTS dichotomized at ≥8 versus <8. Primary outcome measure was favorable outcome (modified Rankin Scale scores 0–3). Secondary outcome measures were mortality and functional independence (modified Rankin Scale scores 0–2). Results— Of 158 patients included, 78 patients had a CT angiography source images pc-ASPECTS ≥8. Patients with a pc-ASPECTS ≥8 more often had a favorable outcome than patients with a pc-ASPECTS <8 (crude RR, 1.7; 95% CI, 0.98–3.0). After adjustment for age, baseline National Institutes of Health Stroke Scale score, and thrombolysis, pc-ASPECTS ≥8 was not related to favorable outcome (RR, 1.3; 95% CI, 0.8–2.2), but it was related to reduced mortality (RR, 0.7; 95% CI, 0.5–0.98) and functional independence (RR, 2.0; 95% CI, 1.1–3.8). In post hoc analysis, pc-ASPECTS dichotomized at ≥6 versus <6 predicted a favorable outcome (adjusted RR, 3.1; 95% CI, 1.2–7.5). Conclusions— pc-ASPECTS on CT angiography source images independently predicted death and functional independence at 1 month in the CT angiography subgroup of patients in the BASICS registry.

Follow Up Study

Background and Objective: To report the results of clinical follow-up at 1 year among patients in the BASILAR registry. Design, Setting, and Participants: The BASILAR study was an investigator-initiated prospective registry, which consecutively enrolled stroke patients with acute basilar artery occlusion from 47 comprehensive stroke centers in China between January, 2014, and May, 2019. Patients were divided into conventional treatment or endovascular treatment groups according to the treatment their received. We assessed clinical outcomes 1 year after patients were enrolled in the BASILAR registry. Main Outcomes and Measures: The primary outcome was the score on the modified Rankin scale (range, 0 to 6 points, with higher scores indicating more severe disability) at 1 year assessed as a common odds ratio using ordinal logistic regression shift analysis, adjusted for prespecified prognostic factors. Secondary outcomes included categories scores of the modified Rankin scale at 1 year (0 to 1 [excellent outcome], 0 to 2 [good outcome], and 0 to 3 [favorable outcome]), and death from any cause during the 1-year period after enrollment. Results: Of the 829 patients who were enrolled in the original study, 1-year data for this extended follow-up study were available for 785 patients (94.7%). The distribution of outcomes on the modified Rankin scale favored endovascular treatment over conventional treatment (adjusted common odds ratio, 4.50; 95% confidence interval [CI], 2.81 to 7.29; P < 0.001). There were significant differences between the treatment groups in the percentage of patients who had excellent outcome, good outcome and favorable outcome. The cumulative 1-year mortality rate was 54.6% in the endovascular treatment group and 83.5% in the conventional treatment group (adjusted hazard ratio, 4.36; 95% CI, 2.69 to 7.29; P < 0.001). Conclusions and Relevance: In this extended follow-up study, the beneficial effect of endovascular treatment on functional outcome at 1 year in patients with acute basilar artery occlusion was similar to that reported at 90 days in the original study.

Background and Purpose: The BASILAR registry, a nationwide prospective nonrandomized study conducted in China, enrolled consecutive patients with acute basilar artery occlusion receiving endovascular treatment or conventional-treatment from January 2014 to May 2019. This article aimed to report the results of clinical follow-up at one year among these patients. Methods: The primary outcome was the modified Rankin Scale at one year, assessed as a common odds ratio using ordinal logistic regression analysis adjusted for prespecified prognostic factors. Secondary outcomes included the modified Rankin Scale-based outcome group at one year (0–1, 0–2, or 0–3) and all-cause death. Results: Of the 829 patients enrolled in the original BASILAR registry, one-year data were available for 785 patients (94.7%). The distribution of outcomes on the modified Rankin Scale favored endovascular treatment over conventional-treatment (adjusted common odds ratio, 4.50 [95% CI, 2.81–7.29]; P <0.001). The cumulative one-year mortality rate was 54.6% in the endovascular treatment group versus 83.5% in the conventional-treatment group (adjusted odds ratio, 4.36 [95% CI, 2.69–7.29]; P <0.001). Conclusions: The beneficial effect of endovascular treatment on functional outcome at one year in patients with acute basilar artery occlusion is similar to that reported at 90 days in the original study.

Background: Tenecteplase (TNK) is a genetically modified variant of alteplase with greater fibrin specificity and longer half-life than alteplase. The recent Tenecteplase versus Alteplase before Endovascular Therapy for Ischemic Stroke (EXTEND-IA TNK) trial demonstrated that increased reperfusion with TNK compared to alteplase prior to endovascular thrombectomy (EVT) in large vessel occlusion ischaemic strokes. However, only 6 patients with basilar artery occlusion (BAO) were included. We aimed to investigate the efficacy of TNK versus alteplase before EVT in patients with basilar artery occlusion (BAO). Methods: Clinical and procedural data of consecutive BAO diagnosed on CT Angiography or MR Angiography from the multisite international Basilar Artery Treatment and MANagement (BATMAN) collaboration were retrospectively analysed. The primary outcome was reperfusion of greater than 50% of the involved ischemic territory or absence of retrievable thrombus at the time of the initial angiographic assessment. Results: We included 119 BAO patients treated with intravenous thrombolysis prior to EVT; mean age 68 (SD 14), median NIHSS 16 (IQR 7-32). Eleven patients were treated with TNK (0.25mg/kg or 0.4mg/kg) and 108 with alteplase (0.9mg/kg). Overall, 113 patients had catheter angiography or early repeat imaging after thrombolysis. Reperfusion of greater than 50% of the ischemic territory or absence of retrievable thrombus occurred in 4/11 (36%) of patients treated with TNK vs 8/102 (8%) treated with alteplase (p=0.02). Onset-to-needle time did not differ between the two groups (p=0.4). Needle-to-groin-puncture time was 61 (IQR 33-100) mins in patients reperfused with TNK vs 111 (IQR 86-198) mins in patients reperfused with alteplase (p=0.048). Overall, the rate of symptomatic haemorrhage was 3/119 (2.5%). No differences were found in the rate of symptomatic intracranial haemorrhage (p=0.3) between the two thrombolytic agents. Conclusions: Despite shorter needle-to-groin-puncture times, tenecteplase was associated with an increased rate of reperfusion in comparison with alteplase before EVT in BAO. Randomized controlled trials to compare tenecteplase with alteplase in BAO patients before endovascular thrombectomy are warranted.

Endovascular Thrombectomy

ABSTRACT:Background and Purpose:Large prospective observational studies have cast doubt on the common assumption that endovascular thrombectomy (EVT) is superior to intravenous thrombolysis for patients with acute basilar artery occlusion (BAO). The purpose of this study was to retrospectively review our experience for patients with BAO undergoing EVT with modern endovascular devices.Methods:All consecutive patients undergoing EVT with either a second-generation stent retriever or direct aspiration thrombectomy for BAO at our regional stroke center from January 1, 2013 to March 1, 2019 were included. The primary outcome measure was functional outcome at 1 month using the modified Rankin Scale (mRS) score. Multivariable logistic regression was used to assess the association between patient characteristics and dichotomized mRS.Results:A total of 43 consecutive patients underwent EVT for BAO. The average age was 67 years with 61% male patients. Overall, 37% (16/43) of patients achieved good functional outcome. Successful reperfusion was achieved in 72% (31/43) of cases. The median (interquartile range) stroke onset to treatment time was 420 (270–639) minutes (7 hours) for all patients. The procedure-related complication rate was 9% (4/43). On multivariate analysis, posterior circulation Alberta stroke program early computed tomography score and Basilar Artery on Computed Tomography Angiography score were associated with improved functional outcome.Conclusion:EVT appears to be safe and feasible in patients with BAO. Our finding that time to treatment and successful reperfusion were not associated with improved outcome is likely due to including patients with established infarcts. Given the variability of collaterals in the posterior circulation, the paradigm of utilizing a tissue window may assist in patient selection for EVT. Magnetic resonance imaging may be a reasonable option to determine the extent of ischemia in certain situations.

Acute basilar artery (BA) occlusion has a very poor prognosis. Recanalization can be challenged by bilateral vertebral artery (VA) occlusions, arterial dissection, or advanced atherosclerotic disease. We describe a case in whom the BA was accessed and recanalized through a retrograde-antegrade approach from the anterior circulation using a large posterior communicating artery (PCOM). Once the BA had been crossed retrogradely through the PCOM, another microcatheter was advanced antegradely through the VA into the BA and right posterior cerebral artery using the “buddy-wire” technique. In this way the BA was recanalized and reconstructed with stents. This technical note demonstrates a new approach to BA treatment when the antegrade access is hampered by advanced VA/BA disease or dissection.

Objective:To investigate the efficacy of tenecteplase (TNK), a genetically modified variant of alteplase with greater fibrin specificity and longer half-life than alteplase, prior to endovascular thrombectomy (EVT) in patients with basilar artery occlusion (BAO).Methods:To determine whether tenecteplase is associated with better reperfusion rates than alteplase prior to EVT in BAO, clinical and procedural data of consecutive BAO patients from the Basilar Artery Treatment and MANagement (BATMAN) registry and the Tenecteplase versus Alteplase before Endovascular Therapy for Ischemic Stroke (EXTEND-IA TNK) trial were retrospectively analyzed. Reperfusion >50% or absence of retrievable thrombus at the time of the initial angiogram was evaluated.Results:We included 110 BAO patients treated with intravenous thrombolysis prior to EVT [mean age 69(SD 14); median NIHSS 16(IQR 7-32)]. Nineteen patients were thrombolysed with TNK (0.25mg/kg or 0.40mg/kg) and 91 with alteplase (0.9mg/kg). Reperfusion>50% occurred in 26% (n=5/19) of patients thrombolysed with TNK vs 7% (n=6/91) thrombolysed with alteplase (RR 4.0 95%CI 1.3-12; p=0.02), despite shorter thrombolysis-to-arterial-puncture time in the TNK-treated patients (48[IQR 40-71]mins) vs alteplase-treated patients (110[IQR 51-185]mins, p=0.004). No difference in symptomatic intracranial hemorrhage was observed (0/19(0%) TNK, 1/91(1%) alteplase, p=0.9).Conclusions:Tenecteplase may be associated with an increased rate of reperfusion in comparison with alteplase before EVT in BAO. Randomized controlled trials to compare tenecteplase with alteplase in BAO patients are warranted.Classification of evidence:This study provides Class III evidence that tenecteplase leads to higher reperfusion rates in comparison with alteplase prior to EVT in BAO patients.
