Anchoring Technique

BackgroundCraniocervical catheter access in large vessel occlusion acute ischemic strokes can be challenging in cases of unfavorable aortic arch/cervical vascular anatomy, leading to lower recanalization rates, increased procedural time and worse clinical outcomes. We aim to demonstrate the feasibility of the balloon-anchoring technique (BAT) that can be attempted before switching to alternative access sites.MethodsRetrospective review of prospectively collected information on 11 patients in which two variants of the BAT (proximal anchoring: balloon guide catheter (BGC) is inflated to provide support for distal access; distal anchoring: compliant balloon is inflated in an intracranial artery to allow advancement of the support system) were utilized to facilitate craniocervical access due to failure of conventional maneuvers.ResultsTen patients had anterior and one patient had posterior circulation large vessel occlusions. Mean age was 81 years and 81% were females. Type 3 arches were found in 82% and a 9 French balloon guide catheter was used in 82%. Proximal anchoring with BGC was used in four cases while distal anchoring was used in seven patients to allow access to the target vessel, avoiding the need to puncture alternative access sites. Successful reperfusion (modified treatment in cerebral ischemia 2b-3) was achieved in all cases and no complications were observed.ConclusionBAT is safe and feasible. It can be considered as a rescue maneuver in order to avoid switching to a different access during thrombectomy in individuals with unfavorable aortic arch/craniocervical anatomy.

BackgroundA transradial approach (TRA) is associated with fewer access site complications than a transfemoral technique (TFA).However, there is concern that performing mechanical thrombectomy (MT) via TRA may lead to longer revascularization times and thus worse outcomes. Nonetheless, TRA may confer added benefits in MT since navigation of challenging aortic arch and carotid anatomy is often facilitated by a right radial artery trajectory.ObjectiveTo compare outcomes in patients who underwent MT via TRA versus TFA.MethodsWe performed a retrospective review of our institutional database to identify 51 patients with challenging vascular anatomy who underwent MT for anterior circulation large vessel occlusion between February 2015 and February 2018. Patient characteristics, procedural techniques, and outcomes were recorded. TFA and TRA cohorts were compared.ResultsOf the 51 patients, 18 (35%) underwent MT via TRA. There were no significant cohort differences in patient characteristics, clot location, or aortic arch type and presence of carotid tortuosity. There were no significant differences in outcomes between the two cohorts, including single-pass recanalization rate (54.5% vs 55.6%, p=0.949) and average number of passes (1.9 vs 1.7, p=0.453). Mean access-to-reperfusion time (61.9 vs 61.1 min, p=0.920), successful revascularization rates (Thrombolysis in Cerebral Infarction score ≥2b 87.9% vs 88.9%, p=1.0) and functional outcomes (modified Rankin Scale score≤2, 39.4% vs 33.3%, p=0.669) were similar between TFA and TRA cohorts, respectively.ConclusionsOur results demonstrate equivalence in efficacy and efficiency between TRA and TFA for MT of anterior circulation large vessel occlusion in patients with challenging vascular anatomy. TRA may be better than TFA in well-selected patients undergoing MT.

BackgroundBalloon guide catheter (BGC) in stent retriever based thrombectomy (BGC+SR) for patients with large vessel occlusion strokes (LVOS) improves outcomes. It is conceivable that the addition of a large bore distal access catheter (DAC) to BGC+SR leads to higher efficacy. We aimed to investigate whether the combined BGC+DAC+SR approach improves angiographic and clinical outcomes compared with BGC+SR alone for thrombectomy in anterior circulation LVOS.MethodsConsecutive patients with anterior circulation LVOS from June 2019 to November 2020 were recruited from the ROSSETTI registry. Demographic, clinical, angiographic, and outcome data were compared between patients treated with BGC+SR alone versus BGC+DAC+SR. The primary outcome was first pass effect (FPE) rate, defined as near complete/complete revascularization (modified Thrombolysis in Cerebral Infarction (mTICI) 2c–3) after single device pass.ResultsWe included 401 patients (BGC+SR alone, 273 (66.6%) patients). Patients treated with BGC+SR alone were older (median age 79 (IQR 68–85) vs 73.5 (65–82) years; p=0.033) and had shorter procedural times (puncture to revascularization 24 (14–46) vs 37 (24.5–63.5) min, p<0.001) than the BGC+DAC+SR group. Both approaches had a similar FPE rate (52% in BGC+SR alone vs 46.9% in BGC+DAC+SR, p=0.337). Although the BGC+SR alone group showed higher rates for final successful reperfusion (mTICI ≥2b (86.8% vs 74.2%, p=0.002) and excellent reperfusion, mTICI ≥2 c (76.2% vs 55.5%, p<0.001)), there were no significant differences in 24 hour National Institutes of Health Stroke Scale score or rates of good functional outcome (modified Rankin Scale score of 0–2) at 3 months across these techniques.ConclusionsOur data showed that addition of distal intracranial aspiration catheters to BGC+SR based thrombectomy in patients with acute anterior circulation LVO did not provide higher rates of FPE or improved clinical outcomes.

Introduction: Mechanical Thrombectomy (MT) is currently the standard of care for patients presenting with emergent large vessel occlusion (ELVO) with salvageable tissue. A subgroup of patients with ELVO are found to have refractory occlusion due to underlying intracranial atherosclerosis (ICAS), often requiring angioplasty with or without stenting. Whether this treatment is safe or effective in this group of patients remains to be established. The purpose of this study is to investigate the safety, efficacy and long-term outcome of MT with rescue therapy in patients with ICAS. Methods: STAR registry combined prospectively maintained databases of 11 thrombectomy-capable centers in the US, Europe and Asia. In this analysis, we included patients who underwent rescue balloon angioplasty and/or stenting in the setting of ELVO. A matched sample was produced by matching on the variables of age, admission NIHSS, and location of occlusion. Results: Out of 2827 thrombectomy patients included in STAR registry, 190 patients received MT and required rescue angioplasty and/or stenting. Balloon angioplasty was performed on 116 patients, and 84 patients had intracranial stenting. Compared to the 161 ICAS patients matched to similar number of controls. There was no difference in age, race, sex, rate of IV tPA administration, ASPECTS score, or onset to groin time. Successful first attempt was higher in patients with embolic LVO (22 vs 52, p=0.001), procedural time was longer in patients with ICAS (47 min Vs 31 min, p=<0.001). There was no difference in symptomatic intracranial hemorrhage, or long term functional outcome. Conclusion: In patients with ELVO with underlying ICAS requiring rescue angioplasty and/or stenting; despite longer procedural time and lower rate of first pass revascularization, rescue therapy appears to be safe with similar complication rates and long-term functional outcomes compared to patients with large vessel occlusion from embolic source.

Procedural Outcomes

BackgroundThe use of a balloon-guide catheter (BGC) in acute stroke treatment has been widely adopted after demonstrating optimized procedure metrics and outcomes. Initial technical constraints of previous devices included catheter stiffness and smaller inner diameters. We aim to evaluate the performance and safety of the Walrus BGC, a variable stiffness catheter with a large bore 0.087 inch inner diameter (ID), via the the WICkED study (Walrus Large Bore guide Catheter Impact on reCanalization first pass Effect anD outcomes).MethodsThis is a retrospective, site adjudicated, multicenter study on consecutive patients with large vessel occlusion treated with the Walrus BGC. Baseline characteristics, procedural outcomes and functional outcomes were analyzed.ResultsA total of 338 patients met the inclusion criteria. The Walrus was successfully tracked into distal vasculature and allowed therapeutic device delivery in all but 3 cases (0.9%). Large aspiration catheters ≥0.070 inch ID were used in 71.9% of cases. Stent retriever thrombectomy was used as the first-line modality in 59.2% and thromboaspiration in 40.8% of cases. The successful recanalization rate (modified treatment in cerebral ischemia (mTICI) 2b/3) was 94.4%, with 64.8% of the patients achieving mTICI 2b/3 after the first pass. The Walrus-related adverse event rate was 0.6%, corresponding to two vessel dissections. Functional independence was 50% (126/252) and mortality 25% (63/252). Unfavorable outcomes were more likely in older patients, who had unsuccessful reperfusion, longer procedure times, and a higher mean number of passes.ConclusionIn acute ischemic stroke patients presenting with large vessel occlusion, the Walrus BGC demonstrated excellent navigability and safety profile, allowed the accommodation of leading large bore aspiration catheters, and demonstrated high vessel recanalization rates.

The Impact

Introduction: Clinical trials have proven the safety and efficacy of mechanical thrombectomy (MT) with intravenous alteplase (tPA) compared to tPA alone in patients presenting with large vessel occlusion (LVO). The impact of tPA prior to MT on procedural metrics, successful revascularization, symptomatic hemorrhage and long-term functional outcome has not been established from large scale real-world studies. In this study we evaluate the impact of tPA prior to MT on procedural times, immediate and long-term outcomes. Methods: The STAR registry combined prospectively maintained databases of 11 thrombectomy-capable stroke centers in the US, Europe and Asia. Patients who received mechanical thrombectomy with or without intravenous tPA prior to MT were included in these analyses. Baseline characteristics, procedural time, successful revascularization (TICI ≥ 2B), symptomatic intracranial hemorrhage (PH2), and long-term functional outcomes were compared between the two groups. Results: Total of 1869 patients were included in this analysis. Of those, 907 received tPA prior to MT. Baseline features and outcomes are summarized in table 1. There were more white patients in the non-tPA group, and more patients in this group had atrial fibrillation and hyperlipidemia; otherwise there were no differences in baseline features between the two groups. Median NIHSS on admission was 16 in both groups, median ASPECTS was 9 in the tPA group versus 8 in the non-tPA group, p=0.208. Patients in the tPA group had higher rate of successful revascularization, lower number of revascularizations attempts and were more likely to achieve excellent long-term functional outcome. There was no difference in procedural time, rate of symptomatic hemorrhage or length of hospital stay. Conclusion: Bridging therapy with intravenous tPA prior to mechanical thrombectomy may facilitate MT and yield to better long-term functional outcome.

Background: Among thrombectomy techniques, Continuous Aspiration Prior to Intracranial Vascular Embolectomy (CAPTIVE) is associated with higher rates of recanalization. Initially, CAPTIVE was performed without a balloon guide catheter (BGC). We aimed to determine the association between BGC usage with final recanalization as well as first pass effect in patients with anterior circulation emergent large vessel occlusion. Methods: We retrospectively reviewed consecutive patients with ICA and M1 occlusions treated with thrombectomy using CAPTIVE over a 45-month period. Post-treatment angiograms were scored by an experienced neurointerventionalist who was blinded to BGC usage and clinical outcome. For both BGC and non-BGC groups, we compared degree of recanalization (using the mTICI 2c scale), first-pass successful recanalization (mTICI 2c/3), and time to recanalization. We examined these results for all patients as well as based on clot location (ICA vs. M1). Results: 357 patients met criteria (median age: 73, median NIHSS: 17) for whom BGC was used in 37/70 (53%) with ICA and 116/287 (40%) with M1 occlusion. Odds of successful reperfusion increased 2.4-fold and odds of complete reperfusion increased 3-fold using BGC (both p<.01). Odds of successful first-pass recanalization (mTICI 2c/3) increased 5-fold for ICA occlusions (p=.004) and 1.7-fold for M1 (p=.03) (See Figure). Recanalization time with BGC for ICA occlusions was faster (22 vs. 36 min, p=.02) but there was no difference in time for M1 occlusions (24 vs. 26 min). Conclusions: BGC usage with the CAPTIVE technique is associated with higher recanalization rates, markedly higher first pass effect (mTICI 2c/3) for both ICA and M1 occlusions, and faster recanalization for ICA occlusions.

IntroductionThe Solitaire stent retriever registry showed improved reperfusion, faster procedure times, and better outcome in acute stroke patients with large vessel occlusion treated with a balloon guide catheter (BGC) and Solitaire stent retriever compared with a conventional guide catheter. The goal of this study was to evaluate whether use of a BGC with the Trevo stent retriever improves outcomes compared with a conventional guide catheter.MethodsThe TRACK registry recruited 23 sites to submit demographic, clinical, and site adjudicated angiographic and outcome data on consecutive patients treated with the Trevo stent retriever. BGC use was at the discretion of the physician.Results536 anterior circulation patients (of whom 279 (52.1%) had BGC placement) were included in this analysis. Baseline characteristics were notable for younger patients in the BGC group (65.4±15.3 vs 68.1±13.6, P=0.03) and lower rate of hypertension (72% vs 79%, P=0.06). Mean time from symptom onset to groin puncture was longer in the BGC group (357 vs 319 min, P=0.06).Thrombolysis in Cerebral Infarction 2b/3 scores were higher in the BGC cohort (84% vs 75.5%, P=0.01). There was no difference in reperfusion time, first pass effect, number of passes, or rescue therapy. Good clinical outcome at 3 months was superior in patients with BGC (57% vs 40%; P=0.0004) with a lower mortality rate (13% vs 23%, P=0.008). Multivariate analysis demonstrated that BGC use was an independent predictor of good clinical outcome (OR 2; 95% CI 1.3 to 3.1, P=0.001).ConclusionsIn acute stroke patients presenting with anterior circulation large vessel occlusion, use of a BGC with the Trevo stent retriever resulted in improved reperfusion, improved clinical outcome, and lower mortality.
