Safety and efficacy of the use of large bore intermediate suction catheters alone or in combination for the treatment of acute cerebral venous sinus thrombosis: A multicenter experience
Abstract:Background and purpose Systemic anticoagulation is the standard treatment for cerebral venous sinus thrombosis (CVST). Several endovascular techniques have been described as salvage therapy for anticoagulation refractory CVST cases. We aim to evaluate the safety and feasibility of endovascular aspiration thrombectomy using the new generation, large bore suction catheters alone or in combination with stentriever devices for the treatment of CVST.

“…Occasionally, the catheter is left in situ for 24 h or more [ 16 , 17 ]. In addition, several endovascular techniques have been discussed and investigated: rheolytic catheter thrombectomy, direct aspiration thrombectomy, balloon-guided thrombectomy or angioplasty and stent retriever thrombectomy [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Information on EVT in SVT is sparse and is based primarily on case series and anecdotal data and only a single published randomized controlled trial (RCT) [ 19 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ].…”
Background: Cerebral venous sinus or vein thromboses (SVT) are treated with heparin followed by oral anticoagulation. Even after receiving the best medical treatment, numerous patients experience neurological deterioration, intracerebral hemorrhage or brain edema. Debate regarding whether endovascular treatment (EVT) is beneficial in such severe cases remains ongoing. This systematic review summarizes the current evidence supporting the use of EVT for SVT on the basis of case presentations, with a focus on patient selection, treatment strategies and the effects of the COVID-19 pandemic. Methods: This systemic literature review included randomized controlled trials (RCTs) and retrospective observational data analyzing five or more patients. Follow-up information (modified Rankin scale (mRS)) was required to be provided (individual patient data). Results: 21 records (n = 405 patients; 1 RCT, 20 observational studies) were identified. EVT was found to be feasible and safe in a highly selected patient cohort but was not associated with an increase in good functional outcomes (mRS 0–2) in RCT data. In observational data, good functional outcomes were frequently observed despite an anticipated poor prognosis. Conclusion: The current evidence does not support the routine incorporation of EVT in SVT treatment. However, in a patient cohort prone to poor prognosis, EVT might be a reasonable therapeutic option. Further studies determining the patients at risk, choice of methods and devices, and timing of treatment initiation are warranted.

Background Cerebral venous thrombosis (CVT) is a rare thrombotic condition which is traditionally treated with anti-coagulation therapy. Subsets of patients with severe CVT have been treated with endovascular thrombectomy (EVT). Despite the high estimated mortality associated with severe CVT, there has been only one randomized control trial done regarding safety and efficacy of EVT in severe CVT compared to standard medical management. Evidence in this area is lacking. Objective The aim of this systematic review is to analyze all existing literature and generate robust information regarding the role of EVT in the management of patients with severe CVT. Methods This systematic review and meta-analysis followed PRISMA guideline. PubMed, Embase, Google Scholar, and CNKI were searched for eligible studies from 2007 to 2021. Safety and efficacy of EVT were evaluated by meta-analyzing recanalization status, the good functional outcome at follow-up, recurrent CVT, new hematoma. A pooled proportion with a 95% confidence interval was derived from a meta-analysis of various outcomes (CI). Results A total of 33 studies comprising 610 patients treated with EVT were included for analysis which comprised one randomized control trial, one prospective study and 31 retrospective studies. Based on pooled data, 85% of patients had good functional outcome, 62% had complete recanalization, 5% had all-cause mortality, and 3% had catheter related complications. The efficacy outcomes in this analysis had a significant heterogeneity and a subgroup analysis was also done to explain these findings. The minimum time of follow up was 3 months and varied EVT techniques were used across the studies. Conclusion This meta-analysis suggests EVT may be safe and efficacious in treating patients with severe CVT. Registration Our protocol was registered with PROSPERO: International prospective register of systematic reviews with the registration number CRD42021254760.
“…Small case series demonstrate the utility and safety of large-bore aspiration catheters in cerebral venous thrombosis. 15 In particular, given the association of cerebral sinus thrombosis with infections, such as coronavirus disease 2019, continued refinement of approaches for effective treatment is urgently required. One of the additional benefits of a large-bore aspiration system, such as the BMX™ 96, in the setting of ADAPT is the reduced cost compared to more traditional catheters that are typically used in conjunction with stents and/or BCGs.…”
Endovascular thrombectomy (EVT) is part of first-line intervention for acute ischemic stroke management. Recent technological advances have demonstrated that large-bore catheters are an attractive approach for EVT. A multitude of approaches such as A Direct Aspiration first Pass Technique (ADAPT) or in conjunction with stent retrieval (Solumbra technique) have been developed with increasingly large-bore catheters, demonstrating safety and efficacy. Furthermore, these techniques have demonstrated promise for the intervention of cerebral venous thrombosis as well as posterior circulation ischemic events. Recently, advances in neurointerventional catheters have focused on improved maneuverability to navigate the neurovasculature, as well as larger inner diameters for improved procedural versatility, including aspiration. We describe a case report highlighting our early institutional experience with the recently developed large-bore catheter, the BENCHMARK™ BMX™ 96. The case report entails near complete occlusion of the internal carotid artery from acute thrombus and the utility of the BMX™ 96 catheter for treatment of such extensive clot burden. The applicability of large-bore aspiration catheters, with an emphasis on recent advances, for mechanical thrombectomy in arterial as well as venous systems is discussed. To our knowledge, this is the first reported case of use of the BENCHMARK™ BMX™ 96 access system for EVT in acute ischemic stroke. Such new-generation large-bore catheters are a promising advance in neurointervention, and our early institution experience highlights the ease of use and versatility for neurointerventional procedures such as EVT.
