Köksoy told ESVS delegates that, in terms of early clot removal, each modality has its advantages and disadvantages. He added, "Pharmacomechanical thrombectomy refers to catheter-directed administration of a fibrinolytic drug directly into the venous thrombus with concomitant use of catheter-based devices to macerate the thrombus and speed thrombus removal. Pharmacomechanical thrombectomy can enable complete on-table removal of a thrombus in a single, one- to three-hour procedure, reducing the overall thrombolysis infusion time, dosage and length of stay.". He said that there have been observational studies but no randomised trials in this area. "No single pharmacomechanical thrombectomy method is clearly superior to others. Catheter-directed thrombolysis with long lytic infusions is likely to be less efficient and less safe than pharmacomechanical thrombectomy and most endovascular surgeons or interventionalists prefer faster pharmacomechanical methods that use lower doses of tPA and ...

In patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI), a strategy of routine manual thrombectomy did not reduce the risk of cardiovascular death, recurrent myocardial infarction, cardiogenic shock or class IV heart failure within 180 days, as compared to PCI alone with only bailout thrombectomy, according to results of the TOTAL trial presented Monday, March 16 as a part of ACC.15 and simultaneously published in the New England Journal of Medicine.. A total of 10,732 STEMI patients were divided in to two groups, the first of which underwent PCI with manual thrombectomy and the second group received PCI alone. Both groups were monitored for death due to cardiovascular causes within 180 days.. The results indicated that neither strategy was statistically superior after 180 days, as shown by a 6.9 percent rate of mortality in the thrombectomy group versus 7.0 percent in those who received PCI alone. The rates of cardiovascular death ...
THERAPY sought to establish the benefit of aspiration thrombectomy in conjunction with intravenous-alteplase when compared with intravenous-alteplase alone in patients with a large anterior circulation proximal clot burden (≥8 mm), but it was halted early based on external evidence demonstrating the efficacy of thrombectomy.6-10 Consequently, THERAPY was not powered to meet its predefined end points. Although the primary end point was not achieved, prespecified secondary end points suggest potential for benefit for aspiration thrombectomy (Figure 2A). In addition, although nonsignificant, the magnitude of potential treatment effect observed for the primary outcome measure is consistent with those of the recent positive thrombectomy trials (Figure 2B). Finally, similar to ESCAPE (The Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Times) and EXTEND-IA (Extending the Time for Thrombolysis in Emergency Neurological ...
Mechanical thrombectomy is a treatment for stroke that removes clots that block large blood vessels. Some patients may be candidates for this procedure using an angiogram or a catheterization and a device that grabs clots and removes them, to re-establish blood flow to the brain. Unfortunately, not everyone is a candidate for mechanical thrombectomy, because it requires that a patient has a large vessel thats blocked.. NHS England announced in April 2017 that it will commission mechanical thrombectomy so it can become more widely available for patients who have certain types of acute ischaemic stroke.. In 2016, St Georges Hospital became the first, and to date only, hospital in the UK to have a fully staffed 24/7 mechanical thrombectomy service for acute stroke. The Atkinson Morley Regional Neurosciences Centre at St Georges University Hospitals NHS Foundation Trust is where the emergency treatment is undertaken with a highly-skilled team with staff from Interventional Neuroradiology, Stroke ...
Introduction: Despite level 1a evidence demonstrating the clinical benefit of mechanical thrombectomy in selected large vessel ischemic stroke patients, a gender disparity exists. Women not only have less favorable clinical outcomes after all stroke types, but the causes of this disparity remain elusive. Gender differences in cerebral vascular anatomy have been previously published. We hypothesize that differences in circle of Willis diameters may contribute to the gender disparity seen in clinical outcomes after mechanical thrombectomy for acute ischemic stroke.. Methods: Clinical and radiographic data from a consecutive series undergoing mechanical thrombectomy for anterior circulation large vessel ischemic strokes were reviewed. Measurements of the proximal middle cerebral artery (M1) segment and supraclinoid internal carotid artery (ICA) diameters were obtained in a standardized fashion from the thrombectomy procedure angiogram. All M1 measurements were recorded at 3 mm of the vessel origin ...

A cross stream thrombectomy catheter with a flexible and expandable cage preferably formed of nitinol for removal of hardened and aged thrombotic material stubbornly attached to the interior of a blood vessel. The cage, which can be mesh or of straight or spiral filament design, is located close to inflow and outflow orifices at the distal portion of a catheter tube and is deployed and extended at a thrombus site for intimate contact therewith and for action of a positionable assembly and subsequent rotation and lineal actuation to abrade, grate, scrape, or otherwise loosen and dislodge difficult to remove thrombus which can interact with cross stream flows to exhaust free and loosened thrombotic particulate through the catheter tube. An alternative embodiment discloses a mechanism involving a threaded tube in rotatable engagement with an internally threaded sleeve to incrementally control the deployment and expansion of the flexible and expandable cages.
The present invention pertains to a miniature flexible thrombectomy catheter having one or more flexible miniature noncollapsing tubular portions including pushable and torqueable structure for introduction into the smaller vessels in neurovascular regions. A jet body having an arcuate fluid jet emanator is incorporated in order to minimize size at the distal portion of a minimally sized catheter tube.

Expedited revascularization through pharmacologic dissolution and/or mechanical thrombectomy is the principle goal of treatment of ischemic stroke [1]. Pharmacologic therapy consists of intravenous thrombolysis with tissue plasminogen activator and is limited by a narrow time window within which to administer the medication, resulting in less than 10% utilization in stroke patients. Mechanical thrombectomy provides another option for flow recanalization. Four thrombectomy devices are cleared by the FDA to restore blood flow in ischemic stroke patients, namely, the Merci retriever, the Penumbra aspiration system, the Solitaire FR revascularization device, and the Trevo device. While several completed and ongoing clinical trials have shown enhancement in the design of thrombectomy devices and increase in recanalization rate [2-4], the recanalization rate and, more importantly, the clinical outcome achieved with current thrombectomy devices still remain to be optimized..

Training a non-radiologist to perform an INR procedure such as coiling a brain aneurysm, or mechanical thrombectomy (MT) for stroke is possible in the UK (a very small number of neurosurgeons from the UK and overseas have been trained to coil aneurysms in UK centres), but as yet there is no GMC approved INR training process for a non-radiologist. To date, supervision of INR training for non-radiologists has been undertaken ad hoc as a local process, complying with local NHS Trust governance procedures. Such informal qualification may not be recognised by other institutions.. The Royal College of Radiologists (RCR) has assembled a multidisciplinary working group to prepare a credential INR (Acute Stroke) that outlines the training required for a non-radiologist to perform aneurysm coiling and mechanical thrombectomy procedures. The GMC has supported credential development and the credential proposal is due to be submitted to the GMC later this year.. The current curriculum for INR training is ...

Methods and Results: Eighteen patients with acute massive PE (Miller score , 20) were included in this study. We separated them into two groups [group A (n = 10), thrombolysis; group B (n = 8): thrombolysis and ROBOT or ROBOT alone]. There was no difference in the hemodynamic indices between the groups at diagnosis. ROBOT was designed to fragment emboli by rotating a regular pigtail ...

Mechanical thrombectomy aims to achieve rapid clot removal by means of different devices instead of the slow pharmacological disintegration of the embolic material after intra-arterial injection. The recent introduction of stent-based thrombectomy has revolutionized the endovascular revascularization of acute large vessel occlusion, with marked improvement in both time and rate of recanalization.15 ,19-22 Until stent-retrievers were introduced into common practice, endovascular management of tandem occlusions was complex, only partially effective, hazardous, and time-consuming.10-13. In this report, we present a case series of 24 patients with acute anterior circulation tandem occlusions treated exclusively with proximal stent-assisted angioplasty immediately followed by stent-based thrombectomy. Our preliminary data on this group of 24 patients suggest that angioplasty and stenting of the proximal occlusion followed by intracranial intervention may be feasible, efficacious, and safe, and may ...

Abciximab vs. Manual Aspiration Thrombectomy in STEMI (pg. 1817): For mere bystanders, the world of interventional cardiology never ceases to amaze with its profusion of trials seeking to compare one odd-sounding intervention with another. The bottom line of this paper about the INFUSE-AMI is that intracoronary abciximab is superior to manual aspiration thrombectomy in patients with large anterior myocardial infarction. I guess you have to be either an interventional cardiologist or a trial methodology dweeb to find this very interesting. Bear with me: I am becoming somewhat of the latter, and to me this looks like a complex marketing trial, and intrigues me like a rare fungus (you can skip to the next section at this point).

BACKGROUND: There is a discrepancy in clinical outcomes and the achieved recanalization rates with stent retrievers in the endovascular treatment of ischemic stroke. It is our hypothesis that procedural release of embolic particulate may be one contributor to poor outcomes and is a modifiable risk. The goal of this study is to assess various treatment strategies that reduce the risk of distal emboli. METHODS: Mechanical thrombectomy was simulated in a vascular phantom with collateral circulation. Hard fragment-prone clots (HFC) and soft elastic clots (SECs) were used to generate middle cerebral artery (MCA) occlusions that were retrieved by the Solitaire FR devices through (1) an 8 Fr balloon guide catheter (BGC), (2) a 5 Fr distal access catheter at the proximal aspect of the clot in the MCA (Solumbra), or (3) a 6 Fr guide catheter with the tip at the cervical internal carotid artery (guide catheter, GC). Results from mechanical thrombectomy were compared with those from direct aspiration using the

Association of Blood Pressure With Short- and Long-Term Functional Outcome After Stroke Thrombectomy: Post Hoc Analysis of the SIESTA Trial. Stroke. 2018. Now that mechanical thrombectomy for acute ischemic stroke has become a well-established treatment, the focus has become how best to manage patients peri-intervention.. As the authors mentioned, two major questions keep arising: What mode of sedation is best for patients undergoing thrombectomy? And, what is the ideal blood pressure goal to maintain before, during, and after intervention?. On the one hand, hypotension in the acute phase of stroke could theoretically lead to hypo-perfusion of the ischemic penumbra, leading to expansion of infarct. On the other hand, it is known that hypertension can increase the risk of intracerebral hemorrhage in patients who receive IV tPA [1], and it is unclear if this could translate to endovascular reperfusion as well. The optimal ...
Desai SM, Rocha M, Molyneaux BJ, Starr M, Kenmuir CL, Gross BA, et al. Thrombectomy 6-24 hours after stroke in trial ineligible patients. Journal of NeuroInterventional Surgery. 2018. If 2014 was the year of the thrombectomy, 2017 to early 2018 was the era of the extended time window. While earlier endovascular trials set the bar at 6 hours (still more permissive than the 4.5-hour limit for IV tPA), there still remained a large proportion of patients for whom we had no acute stroke intervention.. Cue DEFUSE 3 and DAWN. These trials confirmed that there was a benefit in patients up to 16 hours (for DEFUSE 3) and 24 hours (for DAWN) from last known normal (LKN) who received endovascular therapy. Both trials were stopped early at interim analysis, as the results were consistent with a benefit from mechanical thrombectomy (MT) compared to medical treatment. Specifically, in DAWN, 49% of patients in the MT group were functionally independent at 90 days compared to 13% in the control group with a ...

Current therapies for acute stroke are limited to the intravenous administration of a intravenous (IV) recombinant human tissue plasminogen activator (rtPA) for thrombolysis of the affected cerebral arteries within 3-4.5 hours from symptom onset, and the use of intra-arterial (IA) endovascular mechanical clot retrieval devices within 8 hours from ictus, all of which have limitations as mono therapies. For example, IV rtPA may not be very efficacious in large vessel occlusion and the long term effects of mechanical thrombectomy devices on patient functional outcome is unknown. This is a randomized, concurrent controlled study to assess the safety and effectiveness of the Penumbra System as adjunctive therapy to IV rtPA in the acute intervention of acute ischemic stroke. Patients presenting with symptoms of acute ischemic stroke who have evidence of a large clot burden (clot length , 8mm) in the anterior circulation will be assigned to either IV rtPA therapy alone (0.9mg/kg to a maximum of 90mg) ...
Results The Cover-assisted stent retriever thrombectomy significantly reduced the generation of clot fragments ,200 μm as compared with thrombectomy with a CGC, and was similar to the BGC group. Particle size distribution ,200 μm was similar across the groups. All groups were associated with high rates of recanalization, with only one failed recanalization with partial clot retention after three passes in one experiment of stent retriever thrombectomy through a CGC. Use of the adjunctive Cover device did not prolong the procedure as compared with control groups. ...

An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The tubular body has a sufficiently small outside diameter and sufficient kink resistance and pushability to navigate through arteries such as the internal carotid artery.

Mechanical thrombectomy is establishing itself as a crucial tool for the treatment in some patients with acute stroke. However, it is just a part of a chain from the neurological deficit to the final treatment in this common and potentially devastating disease. The radiologist on duty plays a crucial role in this chain along with the neurologist, as and they address important questions in the process of selecting the patients that could benefit from mechanical thrombectomy.. Based on the initial radiological examination, the following questions should be addressed diligently: i) Is there bleeding? ii) Can the site of arterial occlusion be identified (e.g. distal internal carotid artery, middle cerebral artery (M1, M2)? iii) Can a large necrosis brain necrosis be identified? iv) What is the cause of the vascular occlusion (e.g.: dissection)? v) Are the cervical vessels patent (stenosis, occlusion, dissection?).. The most suitable examination (computed tomography (CT) versus magnetic resonance ...

Introduction: In the patients with myocardial infarction, diabetes is the independent risk for worse clinical outcome. Diabetes is supposed to be related to the innate impaired myocardial microcirculation. Nevertheless, the contemporary pharmacological and interventional remedies have yet to show the effectiveness for the preservation of microcirculation after STEMI in diabetic patients. The purpose of this study was to evaluate the impact of thrombectomy and distal protection diabetes on the coronary flow and microcirculation after STEMI.. Methods: Out of 696 STEMI patients enrolled either in the two multicenter randomized trials (VAMPIRE trial: tested the efficacy of thrombectomy or ASPARAGUS trial: tested the efficacy of distal protection device), 360 patients who have complete sets of angiographic data (Ejection fraction [EF] evaluated by left ventriculography, myocardial blush grade [MBG], TIMI grade and corrected TIMI frame count [CTFC]) at baseline and 6-months follow-up were evaluated. ...
In TREVO 2, an open-label randomized controlled trial, the investigators recruited patients at 26 sites in the United States and one in Spain. The investigators included adults ages 18-85 years with angiographically confirmed large-vessel occlusion strokes and US National Institutes of Health Stroke Scale (NIHSS) scores of 8-29 within 8 hours of symptom onset. They randomly assigned patients (1:1) with sequentially numbered sealed envelopes to thrombectomy with Trevo or Merci devices. Randomization was stratified by age (≤68 years vs. 69-85 years) and NIHSS scores (≤18 vs. 19-29) with alternating blocks of various sizes. The primary efficacy endpoint, assessed by an unmasked core laboratory, was thrombolysis in cerebral infarction (TICI) scores of 2 or greater reperfusion with the assigned device alone. The primary safety endpoint was a composite of procedure-related adverse events. Analyses were done by intention to treat.. ...
Thrombectomy is the emergency removal of a blood clot or blood clots from the body. In patients with deep thrombosis a thrombectomy procedure could save a life.
Abbreviation: ISA, incomplete stent apposition.. "We dont know if its the play of chance or some confounding effect," Dr. Serruys said regarding the similarity in minimal flow area between arms. "I was a little bit surprised to see so little difference between thrombectomy and non-thrombectomy.". Would You Treat?. Interestingly, after completion of the trial, OFDI images were sent to the operators, who were asked to judge the necessity of further treatment based on the pictures showing minimum flow area and largest intraluminal mass area. In 38% of cases, at least 1 operator indicated there was a need for further treatment.. Commenting on the trial, panel co-chair Javier Escaned, MD, PhD, of Hospital Clínico San Carlos (Madrid, Spain), noted the numbers needed in the TAPAS trial (over 1,000 patients) to show benefit with thrombectomy compared with the small numbers in TROFI. "Immediately, you realize it will be very difficult to get in a single [study such as this] some information that will ...
BUFFALO, N.Y. - A research team at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo has found that in stroke patients with large vessel occlusion (LVO), the removal of the clot occurs as efficiently after aspiration-based clot removal alone as it does after aspiration-based clot removal performed with a stent retriever. The safety measures and good clinical outcomes produced by both methods, including the incidence of serious, device-related adverse events, were also comparable.. The findings, published today online before print in JAMA Neurology, demonstrate that in many cases of LVO, among the most severe types of stroke, the use of a stent retriever may not always be necessary.. "Our study has found that these two strategies - stent retrieval of the clot versus aspiration of the clot as an initial step - are equivalent in terms of their ability to efficiently achieve recanalization, the restoration of blood flow, and they produce equally successful clinical ...
