The surgical management of acute limb ischaemia due to native vessel occlusion. (1/518)

OBJECTIVES: Data from the STILE study have indicated that for patients with subacute limb ischaemia due to native vessel occlusion, surgery is both more effective, and durable than thrombolysis. The purpose of this study was to evaluate the outcome of an aggressive surgical approach in patients presenting with acute limb-threatening ischaemia. DESIGN: Details of patients presenting with salvageable acute limb ischaemia due to native artery occlusion over a 6-year period in a University hospital vascular unit setting were obtained from the vascular audit and the outcome of the surgical management of these patients was analysed. RESULTS: One hundred and seventy-four consecutive patients underwent surgery for acute native vessel limb ischaemia (76% lower, 24% upper limb). Fogarty thrombectomy or embolectomy was initially performed in 153 (89%) patients. Of these, 37 (24%) immediately underwent a further procedure: 28 (18%) had on-table thrombolysis and 14 (9%) underwent vascular reconstruction. Twenty-six patients (15%) underwent further limb salvage surgery within 30 days. Life table analysis demonstrated a limb salvage rate of 88% and 76% at 30 days and 2 years, respectively. Patient survival was 75% and 48% at the same time intervals. CONCLUSIONS: These results demonstrate that a role for aggressive surgical intervention still exists, resulting in high limb salvage rates.  (+info)

Rapid thrombectomy of superior sagittal sinus and transverse sinus thrombosis with a rheolytic catheter device. (2/518)

Thrombosis of the dural venous sinuses is a potentially lethal condition that remains a diagnostic dilemma. Clinical outcome is typically dependent on the timeliness of diagnosis and definitive treatment. We report a case of successful rapid thrombectomy of extensive thrombus within the superior sagittal and transverse sinuses using a rheolytic catheter device. This appears to be a promising treatment option, particularly in those patients who do not respond to other, more established, forms of therapy.  (+info)

Application of a rheolytic thrombectomy device in the treatment of dural sinus thrombosis: a new technique. (3/518)

We present a novel application of a transvascular rheolytic thrombectomy system in the treatment of symptomatic dural sinus thrombosis in a 54-year-old woman with somnolence and left-sided weakness. The diagnosis of bilateral transverse and superior sagittal sinus thrombosis was made and the patient was treated with anticoagulant therapy. After an initial period of improvement, she became comatose and hemiplegic 8 days after presentation. After excluding intracerebral hemorrhage by MR imaging, we performed angiography and transfemoral venous thrombolysis with a hydrodynamic thrombectomy catheter, followed by intrasinus urokinase thrombolytic therapy over the course of 2 days. This technique resulted in dramatic sinus thrombolysis and near total neurologic recovery. Six months after treatment, the patient showed mild cognitive impairment and no focal neurologic deficit. Our preliminary experience suggests that this technique may play a significant role in the endovascular treatment of this potentially devastating disease.  (+info)

Right heart thrombus: the importance of early intervention. (4/518)

A case report of mobile, right heart thrombus in the accident and emergency (A&E) department is presented. Though frequently associated with major pulmonary embolism, recognition is usually at postmortem examination. Detection of the presence of mobile thrombus in the right heart by early echocardiogram and prompt treatment may be life saving. Surgical or medical treatment options are dependent on local facilities. Early specialist involvement with a contingency plan in A&E departments are advised.  (+info)

Arterialisation of the portal vein with an aortoportal jump graft for portal vein thrombosis following liver resection for malignancy. (5/518)

Fibrolamellar hepatocellular carcinoma (FHCC) is a variant of hepatocellular carcinoma, which mainly affects a young age group and carries a relatively good prognosis. It is widely accepted that aggressive curative resection is still the best option for FHCC. We report here a case of successful arterialisation of the portal vein with an aortoportal jump graft for portal vein thrombosis, which developed postoperatively in an already comprised portal vein with tumour invasion following an extensive liver resection for FHCC.  (+info)

Spinal cord ischemia after abdominal aortic operation: is it preventable? (6/518)

PURPOSE: Spinal cord ischemia after operation on the abdominal aorta is a rare event that is attributed to variations in the spinal cord blood supply. The purpose of this study was to evaluate the possible causes of this devastating event. METHODS: A survey of patients among the members of the Southern Association for Vascular Surgery was performed, and 18 patients were identified with spinal cord ischemia manifested by paraplegia or paraparesis after abdominal aortic operation. RESULTS: Preoperative computed tomographic, magnetic resonance, and aortographic results did not visualize the greater radicular artery (Adamkiewicz's artery) in any patient. Eleven patients underwent resection of infrarenal abdominal aortic aneurysms (AAAs): seven of these patients had tube grafts, three had aortobifemoral grafts, and one had an aortobiiliac graft. Five other patients underwent placement of aortobifemoral grafts, and one patient underwent aortobiiliac graft placement for occlusive disease. One patient underwent suprarenal AAA resection with an interposition graft to a previous aortobiiliac graft. The mean operative time was 3 hours and 39 minutes (range, 2 hours and 45 minutes to 6 hours and 30 minutes), with a mean aortic cross-clamp time of 48 minutes (range, 24 to 97 minutes). Sixteen aortic cross-clamps were placed infrarenally and two suprarenally (one in a case of ruptured AAA, the other a suprarenal AAA). Seventeen proximal anastomoses were end to end. The average minimum systolic blood pressure during the aortic cross-clamping was 96 mm Hg (range, 80 to 130 mm Hg). All the patients had internal iliac artery flow preserved with either prograde perfusion (10 patients) or retrograde perfusion (eight patients), and one patient underwent unilateral internal iliac artery ligation because of aneurysmal disease. One aortobifemoral-graft limb necessitated thrombectomy, but no cases of massive peripheral embolization occurred. When paraplegia was suspected after operation (6 to 20 hours after surgery), five patients underwent lumbar drainage. No clinical improvement was noted. CONCLUSION: Interference with pelvic blood supply from prolonged aortic cross clamping, intraoperative hypotension, aortic embolization, and interruption of internal iliac artery circulation have all been suggested as possible causes of spinal cord ischemia. In this survey, none of these factors proved to be significant as the sole cause of spinal cord ischemia. In the performance of an aortic operation with an end-to-end proximal anastomosis in the presence of severe external or internal iliac artery disease, there may be an increased incidence of spinal cord ischemia despite appropriate surgical techniques to ensure internal iliac perfusion. Spinal cord ischemia after abdominal aortic operations appears to be a tragically unpredictable, random, and unpreventable event.  (+info)

Removal of a thrombus from the sigmoid and transverse sinuses with a rheolytic thrombectomy catheter. (7/518)

A rheolytic thrombectomy catheter was used to remove thrombus without thrombolytics from the sigmoid and transverse sinuses of a 34-year-old woman. Using small, high-flow fluid jets and Venturi-effect suction, this catheter allowed mechanical removal of thrombus. This technique may obviate the need for thrombolytic agents and the risks associated with their use.  (+info)

Eversion endarterectomy versus open thromboendarterectomy and patch plasty for the treatment of internal carotid artery stenosis. (8/518)

OBJECTIVE: in 1996 we changed our treatment for stenosis of the internal carotid artery (ICA) from open thromboendarterectomy and PTFE-patch plasty (TEA) to eversion endarterectomy (EEA). DESIGN: retrospective study. METHODS: a total of 475 EEAs of the ICA were performed between 2/96 and 11/96. These results were compared to the results of TEA carried out between 2/94 and 11/94 (n=388). RESULTS: clamping and operation time were significantly shorter for EEA. Neurological complications included transient ischaemic attacks in 1. 0% in the EEA group versus 1.3% after TEA (p=0.72), minor strokes (0. 6% vs. 1.8%, p=0.10) and major strokes in 1.5% versus 1.1% (p=0.59). The rate of restenosis >50% was 2.5% after EEA and 10.2% after TEA. The only detectable difference of statistical significance in complication rates was in the lesions of the hypoglossal nerve (5.3% vs. 2.6%, p=0.04). CONCLUSIONS: EEA of the ICA is a safe procedure for carotid reconstruction with the additional advantages of short clamping time, possibility of simultaneous shortening of an elongated ICA, and no requirement for patching.  (+info)

Background: High-risk pulmonary embolism is associated with a high early mortality rate. We report our experience with percutaneous mechanical thrombectomy in patients with high-risk pulmonary embolism and contraindications for thrombolytic therapy.. Methods: This was a retrospective analysis of consecutive patients with high-risk pulmonary embolism and contraindications to thrombolytic therapy. They were treated with percutaneous mechanical thrombectomy which included thrombectomy and additional thrombus aspiration when needed. Clinical parameters, clinical success, and survival to discharge were measured.. Results: From November 2005 to September 2015 we treated 25 patients with a mean age of 62.6±12.7 years, 64% were men. Mean simplified Pulmonary Embolism Severity Index was 2,9. Mean maximum lactate levels were 7.8±6.6 mmol/l, vasopressors were used in 77%, 59% needed mechanical ventilation. Mechanical treatment included thrombus fragmentation complemented with aspiration (56%) and ...
In patients with Ilio-femoral veins deep vein thrombosis (IFDVT), early thrombus removal using Catheter Directed Thrombolysis (CDT) or Percutaneous Mechanical Thrombectomy (PMT) plus CDT to decrease the incidence of post thrombotic syndrome and recurrent VTE(1) is advocated by some clinical guidelines(2;3). Despite the potential benefits of CDT +/- PMT, the use of CDT has been associated with an increased risk of pulmonary embolism, intracranial hemorrhage, longer length of stay and higher hospital charges compared to standard anticoagulation(4). Ergo, there is a need to provide a safer and less costly alternatives to CDT +/- PMT to patients with IFDVT. We conducted a prospective single arm single center study aiming evaluate the efficacy of a single session of percutaneous mechanical thrombectomy using the Angiojet in patients with IFDVT,conducted completely as outpatient. Despite effectively reducing thrombus burden in this group of patients the use of this technology lead to a high rate of ...
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 ...
Although primary percutaneous coronary intervention (PPCI) restores epicardial coronary flow in the majority of patients with ST-segment myocardial infarction, this approach can lead to microvascular obstruction resulting from distal embolization of thrombus. Manual thrombectomy (i.e. aspiration thrombectomy) prior to PPCI has been proposed as a method to reduce thrombus burden and resultant distal embolization with PPCI. Although results from early studies of aspiration thrombectomy suggested improvements in patient outcomes, subsequent trials have failed to demonstrate a clinical benefit of aspiration thrombectomy prior to PPCI. This large, multi-centre, international trial furthers the evidence that aspiration does not offer benefit in the routine care of patients undergoing PPCI. This study randomized 10,732 patients with ST elevation myocardial infarction to routine manual thrombectomy prior to PCI or standard PCI alone. The primary outcome was a composite of death from cardiovascular ...

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.

Acute coronary syndrome (ACS) due to embolic phenomenon in the setting of peripartum cardiomyopathy (PPCM) and left ventricular mural thrombus is a rare occurrence. There have been two known cases described in medical literature. We present a unique case in which catheter-based aspiration thrombectomy was used to successfully treat a patient with ACS due to coronary emboli in the setting of PPCMand left ventricular mural thrombus. We believe this to be the first report of the use of aspiration thrombectomy in such a clinical case.. ...
QuickClear simplifies the entire thrombectomy procedure workflow. The small footprint of the sterile device allows it to be placed easily and conveniently on the table next to the patient. With the touch of a button, the system is up and running at maximum aspiration power within seconds. The consistency of the aspiration power during the procedure provides physicians more control and supports faster procedure times. The systems range of catheters includes a large 10F aspiration catheter, providing 59% more aspiration volume than 8F aspiration catheters [1].. QuickClear is a simple and easy to use mechanical thrombectomy system, said Bryan Fisher, MD, Chief of Vascular Surgery, Tristar Centennial Medical Center, Nashville, U.S. The system is significantly smaller than other systems without compromising aspiration power. The convenience of the device really shines through with its single use and lack of capital equipment. I am excited about the potential of this device and the impact it will ...

Institutional review board approval was obtained before starting this retrospective study (IRB No. VC17RISI0036). A total of 161 patients with acute ischemic stroke who underwent stent retrieval thrombectomy at our institution between January 2013 and August 2016 were enrolled. The authors divided the patients into two groups: mechanical thrombectomy for ACO (ACO group) and mechanical thrombectomy for BAO (BAO group). Eligible patients had an occlusion of the internal carotid artery (ICA), middle cerebral artery (M1 or M2), anterior cerebral artery (ACA), or basilar artery, as established by computed tomography angiography (CTA) or perfusion computed tomography (CT) with magnetic resonance image (MRI) diffusion weighted images, and a score of ≥2 on the National Institutes of Health Stroke Scale (NIHSS; range, 0-42, with higher scores indicating more severe neurologic deficits). Patients who received intravenous (IV) alteplase (t-PA) within 4.5 hours after stroke onset with a maximum dose of 90 ...
Now, a multicentre study led by the University of South Florida Health (USF Health) Department of Neurosurgery and Tampa General Hospital, reports that clot perviousness, as estimated by CT imaging, is associated with first-pass success in ELVO patients initially treated with the aspiration thrombectomy approach; which means achieving complete reopening of a blocked artery in the first attempt with a thrombectomy device in the ELVO patients treated with the approach.. The findings from this post hoc analysis of 165 eligible patients enrolled in the COMPASS trial were published on 17 July in the Journal of Neurointerventional Surgery.. The study found that the treatment success of the stent retriever-first approach for an LVO stroke was less dependent on clot perviousness. Time-sensitive, successful removal of the clot restores blood flow and, therefore, oxygen to the brain, improving the likelihood of faster stroke recovery and reduced complications and disability.. Currently, physicians who ...

The Indigo Mechanical Thrombectomy System (Penumbra, Inc., Alameda, California) was used as CDT device. Low-dose local thrombolysis (alteplase, 3-12 mg) was additionally applied in three patients. Technical and procedural success was achieved in 14 patients (100%). Complete or nearly complete clearance of pulmonary arteries was achieved in nine patients (64.3%), whereas partial clearance was achieved in five (35.7%). A significant improvement in the pre- and postprocedural patients clinical status was observed in the

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 ...

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 ...
Background Acute ischemic strokes involving occlusion of large vessels usually recanalize poorly following treatment with intravenous thrombolysis. Recent studies have shown higher recanalization and higher good outcome rates with endovascular therapy compared to best medical management alone. A systematic review and meta-analysis investigating the benefits of all randomized controlled trials (RCTs) of endovascular thrombectomy where at least 25% of patients were treated with a thrombectomy device for the treatment of acute ischemic stroke compared to intravenous thrombolysis has yet to be performed. Aims To perform a systematic review and a meta-analysis evaluating the effectiveness of endovascular thrombectomy compared with best medical care for treatment of acute ischemic stroke. Summary of review Our search identified 437 publications, from which 8 studies (totaling 2,423 patients) matched the inclusion criteria. Overall, endovascular thrombectomy was associated with improved functional outcomes
We discuss a case of early RVT post-transplantation with delayed recovery after immediate open thrombectomy. RVT is generally a catastrophic complication of kidney transplantation, often managed with immediate allograft nephrectomy [1, 2, 17, 18]. Published reports describing cases managed with thrombectomy usually give little information regarding the intra-operative findings or the procedure performed, and often do not detail the duration of oligoanuria post-thrombectomy after which the allograft was deemed non-salvageable [1, 19, 20]. Of the three case reports describing successful thrombectomy that also describe the post-operative course, all three patients were independent from dialysis within 1 week [4, 21]. Our patient demonstrated remarkable renal reserve and regenerative capacity, eventually gaining independence from dialysis 2 weeks post-thrombectomy despite prolonged oliguria and the development of antibody-mediated rejection. We speculate that if a good outcome could be obtained with ...
Per the Multi MERCI protocol, up to 230 patients could be treated at up to 30 centers.. The intended trial indication for the Merci L5 Retriever was to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke. Patients that were contraindicated or failed treatment with intravenous t-PA were allowed to be enrolled under the Multi MERCI protocol.. Per the Multi MERCI protocol, following inclusion of the Merci L5 Retriever the operating physician was required to initiate treatment with the Merci L5 Retriever. At the physicians discretion, subsequent passes could be made with the Merci L5 Retriever, Merci X6 Retriever and/or Merci X5 Retriever.. Adverse events were adjudicated by an independent Data Safety and Monitoring Board (Capital DSMB). ...

Endovascular thrombectomy for large vessel ischaemic stroke substantially reduces disability, with recent positive randomised trials leading to guideline changes worldwide. This review discusses in detail the evidence provided by recent randomised trials and meta-analyses, the remaining areas of uncertainty and the future directions for research. The data from existing trials have demonstrated the robust benefit of endovascular thrombectomy for internal carotid and proximal middle cerebral artery occlusions. Uncertainty remains for more distal occlusions where the efficacy of alteplase is greater, less tissue is at risk and the safety of endovascular procedures is less established. Basilar artery occlusion was excluded from the trials, but with a dire natural history and proof of principle that rapid reperfusion is effective, it seems reasonable to continue treating these patients pending ongoing trial results. There has been no evidence of heterogeneity in treatment effect in clinically defined ...
Portal vein thrombosis (PVT) was for a long time considered a barrier to liver transplantation. The aim of this study is to demonstrate the surgical technical options for portal vein reconstruction during liver transplantation in patients with PVT in which thrombectomy was not possible. Between September 1991 and March 2009, 420 liver transplanted patients were retrospectively analyzed, identifying 29 cases with PVT (6.9%). Preoperative diagnosis, preoperative risk factors, surgical technique options to treat various forms (grades) of PVT, postoperative recurrence and actuarial survival rates were studied. In three cases of PVT grade II and in one case PVT grade III the thrombectomy was insufficient, requiring some surgical technique options (13.79%). In two cases placement of iliac vein graft was performed, in one an anastomosis of the portal vein with collateral splenorenal vein and in the other with left gastric varicose. The actuarial survival rate for patients without PVT and patients with PVT and

The MERCI Retriever is a medical device designed to treat Ischemic Strokes. The name is an acronym for Mechanical Embolus Removal in Cerebral Ischemia. Designed by University of California, Los Angeles in 2001, MERCI was the first device approved in the U.S. to remove blood clots in patients suffering from acute brain ischemia. The MERCI Retriever obtained U.S. FDA clearance in August 2004 for re-canalization of cerebral arteries in acute stroke. Previously, the only available treatment to acute brain strokes was through the use of a protein that breaks down blood clots called tPA. The treatment process itself is termed the r-tPA method (Recombinant Tissue Plasminogen Activator). The success of the r-tPA is strongly dependent on short onset of stroke symptoms, which had to be less than 3 hours. Hemorrhagic complications were also highly likely to occur using the r-tPA method, especially in older brain-stroke patients, which in turn resulted in high mortality rates after the treatment. According ...
The use of trellises to support vine crops such as tomato, squash and cucumber may result in increased fruit quality compared to the conventional practice of allowing the vines to run freely on the ground. Other stated advantages of the trellis system include better canopy light interception, better control of pest and ease of harvesting. However, there is still much debate over whether the use of trellises results in increased yield. The objective of this study was to determine the performance of trellis grown cucumber vs. conventional practice. A two year study was done at the FAMU research and extension center, Quincy Florida. The experimental design was a randomized complete block with three treatments: A-frame trellis, wire trellis and conventional practice as a control. Parameters measured included fruit size (length and circumference), fruit quality and total yield. Treatment effects were evaluated by Analysis of Variance and Fishers exact test. Despite numerically higher numbers of spoiled

BACKGROUND AND PURPOSE: Mechanical thrombectomy (MT) is now the standard of care for large vessel occlusion (LVO) stroke. However, little is known about the frequency and outcomes of repeat MT (rMT) for patients with recurrent LVO. METHODS: This is a retrospective multicenter cohort of patients who underwent rMT at 6 tertiary institutions in the United States between March 2016 and March 2020. Procedural, imaging, and outcome data were evaluated. Outcome at discharge was evaluated using the modified Rankin Scale. RESULTS: Of 3059 patients treated with MT during the study period, 56 (1.8%) underwent at least 1 rMT. Fifty-four (96%) patients were analyzed; median age was 64 years. The median time interval between index MT and rMT was 2 days; 35 of 54 patients (65%) experienced recurrent LVO during the index hospitalization. The mechanism of stroke was cardioembolism in 30 patients (56%), intracranial atherosclerosis in 4 patients (7%), extracranial atherosclerosis in 2 patients (4%), and other causes in

Dr. Adela Cora, a QEII-based Neuroradiologist, recently earned a PhD in stroke thrombectomy from Newcastle University in the UK. Notably, Dr. Cora was the first radiology resident at the school to be enrolled in a new academic/ clinical program allowing her to pursue postgraduate studies alongside her clinical training. She started her studies in 2015 and received her degree this year.. I gained interest in research while pursuing a certificate in neuroimaging research from Edinburgh University from 2013 to 2014, says Dr. Cora. I started my thesis research working on a clinical trial assessing new thrombectomy devices at a time when thrombectomy was still not yet proven. From here I learned that radiology education plays a very important role and I developed a one day intensive CTA course that lead to significant improvement in reporting skills as well as thrombectomy referrals.. In addition, Dr, Cora developed a new anatomy-based scoring system that aims to predict the procedural difficulty ...

This is referred to as thrombectomy within an extended time window. There have been very few studies looking at patients who had seizures within the first week (early post-stroke seizures) following mechanical thrombectomy in this extended time window. Our study suggests that this group of patients does not have a higher incidence of early post stroke seizures. Our findings do reveal however, that patients who do have early post-stroke seizures may have a less favorable ...

Hospitals that accrue higher case volumes for endovascular thrombectomy over time tend to have higher rates of successful recanalization and good outcomes among patients with acute ischemic stroke, according to an analysis recently published online in Stroke. Previous studies suggested that a larger volume of acute stroke patients at a hospital was associated with lower mortality, write the authors, led by Byung Moon Kim, MD (Severance Hospital, Yonsei University College of Medicine, Seoul, South Korea). Those studies involved all acute stroke patients and have not focused on patients who received endovascular treatment.. Prior to the endovascular thrombectomy era, increased hospital endovascular treatment volume for acute stroke was not linked with mortality outcomes in a large retrospective study. Given the recent advent of contact aspiration and stent retriever thrombectomy, the researchers say, it is important to determine whether volume effects on outcome are now apparent.. Kim et al ...
After five positive randomized controlled trials showed benefit of mechanical thrombectomy in the management of acute ischemic stroke with emergent large-vessel occlusion, a multi-society meeting was organized during the 17th Congress of the World Federation of Interventional and Therapeutic Neuroradiology in October 2017 in Budapest, Hungary. This multi-society meeting was dedicated to establish standards of practice in acute ischemic stroke intervention aiming for a consensus on the minimum requirements for centers providing such treatment. In an ideal situation, all patients would be treated at a center offering a full spectrum of neuroendovascular care (a level 1 center). However, for geographical reasons, some patients are unable to reach such a center in a reasonable period of time. With this in mind, the group paid special attention to define recommendations on the prerequisites of organizing stroke centers providing medical thrombectomy for acute ischemic stroke, but not for other ...

One-hundred patients had attempted endovascular treatment. At procedure end, 23% were thrombolysis in cerebral infarction 0-1, 31% thrombolysis in cerebral infarction 2A, 28% thrombolysis in cerebral infarction 2B, and 18% thrombolysis in cerebral infarction 3. More favorable thrombolysis in cerebral infarction-reperfusion scores were associated with greater magnetic resonance imaging reperfusion (P , 0·001). thrombolysis in cerebral infarction scores correlated with 30-day favorable clinical response (P = 0·041) and 90-day modified Rankin Scale 0-2 (P = 0·008). These correlations were significant for target mismatch patients at 30 days (P = 0·034) and 90 days (P = 0·003). Infarct growth was strongly associated with poorer thrombolysis in cerebral infarction scores in target mismatch patients (P , 0·001).

Traditional stroke treatments like clot-dissolving tPA and surgical removal of big clots in the brain are good choices as well when the stroke results from SARS-CoV-2 infection, investigators report.. Excessive blood clotting and stroke-even in young, previously healthy people-are among the myriad of effects the virus is having on people across the globe. Another effect is keeping people away from hospitals even when they experience signs of stroke, like sudden and particularly one-sided weakness in the face, arm or leg, say stroke specialists at the Medical College of Georgia and Augusta University Health System.. What we know about COVID-19 and stroke is people need to be treated urgently and they tend to do really well with tPA and mechanical thrombectomy (clot removal) if they come in within a short time window, says Dr. David Hess, stroke specialist and MCG dean, who encourages those with signs of stroke for any reason to get to the hospital as soon as possible.. Hess and Dr. Elizabeth ...
The window for stroke therapy refers to the time limit after the onset of symptoms when treatment can still be made available. A new study, presented at the European Stroke Organization conference in Prague last month, may extend this window to 24 hours for carefully selected patients. The trial, known as DAWN, selected patients for treatment between 6-24 hours following ischemic stroke. The investigators performed special CT scan or MRI studies to determine which patients had a small area of established damage, but a larger area of potential damage. These patients received endovascular therapy, where a catheter is manipulated into a brain artery, and a retrieval device is used to clear the clot.. The patients treated with endovascular therapy had a 73% reduction in their chance of being dependent following treatment.. The results of this trial carry great importance. Although they pertain to only a very small percentage of stroke patients (these patients were very highly selected), they ...

Bronchoscopy revealed an infiltrated carina, from which an underlying lesion protruded; a biopsy was taken, which was positive for lung adenocarcinoma.. We requested Doppler ultrasound of the lower limbs, which confirmed deep vein thrombosis (DVT) in the right deep femoral/popliteal territory.. Forty-eight hours after admission to Respiratory Medicine, in spite of anticoagulant doses of low molecular weight heparin (LMWH), the patient experienced an episode of intense pain, with coldness and loss of pulse in the right foot. He was assessed by the Vascular Surgery department and diagnosed with acute arterial ischemia (AAI). An emergency thrombectomy was performed (histopathology of the thrombus was negative for malignancy), and sodium heparin infusion was started. The episode recurred at 5 and 14 days after admission. Repeat thrombectomy was performed after the second episode, but given the subsequent functional state of the right lower limb (RLL), pain that could not be controlled with opiate ...
