We report the use of mechanical venous thrombectomy in 2 cases of cerebral venous sinus thrombosis in which the usual first-choice treatment with systemic anticoagulants was contraindicated. Our aim is to present this treatment as an alternative to consider when anticoagulants therapy is too risky or is contraindicated in critically ill patients.

Thrombosis is the most important access-related complication. Several declotting procedures have been suggested falling mainly into two categories; thrombolysis-dependent and thrombectomy dependent. Areas Covered: Seventeen studies after 2001 have been published on percutaneous treatment of thrombosed vascular access. Authors performed a systematic review of these studies together with a parametric meta-analysis of data available investigating clinical success, postintervention assisted primary patency (PAPP) and independent factors that could influence outcome measures...

Blunt abdominal aortic injury (BAAI) is extremely rare. Three known treatments of BAAI exist: medical treatment, conventional surgical treatment, and endovascular treatment. Outcomes of medical and conventional surgical treatments, such as bypass graft, thrombectomy, and intimal suture, were not satisfactory. A 47-year-old man presented with multiple injuries after a high-speed vehicular accident. He was diagnosed with the traumatic aortic injury to be an intra-mural hematoma in the bifurcation of the terminal aorta...

BACKGROUND AND PURPOSE: Clinical triage scales for prehospital recognition of large vessel occlusion (LVO) are limited by low specificity when applied by paramedics. We created the 3-step ambulance clinical triage for acute stroke treatment (ACT-FAST) as the first algorithmic LVO identification tool, designed to improve specificity by recognizing only severe clinical syndromes and optimizing paramedic usability and reliability. METHODS: The ACT-FAST algorithm consists of (1) unilateral arm drift to stretcher <10 seconds, (2) severe language deficit (if right arm is weak) or gaze deviation/hemineglect assessed by simple shoulder tap test (if left arm is weak), and (3) eligibility and stroke mimic screen...

Introduction While effectiveness of mechanical thrombectomy (MTE) in M1 segment occlusion is approved for patients with severe impairment, there is a lack of evidence for a potential benefit of MTE in patients with minor to moderate symptoms. The purpose of this study was to evaluate neurological outcome and occurrence of periprocedural complications after MTE in patients with low National Institutes of Health Stroke Scale (NIHSS) scores. Materials and methods A retrospective analysis of 1081 consecutive patients with anterior circulation ischemic stroke due to M1 occlusion detected by computed tomography angiography and treated with MTE at our hospital between February 2012 and November 2017 was performed...

BACKGROUND: Stroke has become a treatable condition with increasing evidence of treatment benefits in older people. However, stroke mimics in geriatric patients are especially prevalent, causing incorrect suspicion and consecutive burden to patients and emergency room resources. We therefore examined the dimension of this problem by investigating emergency room admissions from nursing homes for suspected stroke. METHODS: We performed a retrospective cohort study of all nursing home residents who were admitted to the neurological emergency room of our primary and tertiary care university hospital between 2013 and 2015...

BACKGROUND: Hepatocellular carcinoma (HCC) can be complicated by major vascular invasion, and resection can be beneficial in some patients.1 Some of these patients are traditionally operated under total vascular exclusion (TVE), refrigeration, extracorporeal circulatory bypass, and cardiac surgery, with high morbidity and mortality.2 However, HCC thrombi are not adherent to the venous wall, and with advances in surgical techniques, resection can be simplified and performed during short-duration TVE alone...

Purpose: Several blood markers have been evaluated in stroke patients, but their role remains limited in clinical practice. This study was designed to evaluate the utility of cell free DNA (cf DNA) in stroke patients undergoing therapeutic intervention in the form of mechanical thrombectomy in acute ischemic stroke patients. Materials and Methods: Twenty-six patients with ischemic stroke who were managed with interventions like intravenous thrombolysis (IVT) and mechanical thrombectomy were recruited consecutively in this study...

Background Many tertiary care hospitals cannot provide a continuous thrombectomy service due to the lack of a neurointerventionalist. Aims In this study, we present procedural and clinical results of a new concept in which neuroradiologists of a university hospital provide neurointerventional stroke service to a remote hospital ("drive the doctor"). Methods All consecutive patients with acute ischemic stroke due to large vessel occlusion of the anterior circulation treated with mechanical thrombectomy after hours at a remote hospital (distance of about 100 km) between 2012 and 2016 were analyzed retrospectively...

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy...

REVIVE SE (REVIVE) is a closed-ended, self-expanding stent retriever used in the RIVER JAPAN study. We present our early experience with REVIVE for revascularization of acute ischemic stroke (AIS) in patients who have failed or are ineligible for intravenous recombinant tissue plasminogen activator treatment. This prospective, single-arm, non-randomized, multicenter registry study followed up patients undergoing mechanical thrombectomy with REVIVE for 90 days. The primary endpoint was a post-procedure Thrombolysis in Cerebral Infarction (TICI) score ≥2a...

BACKGROUND: Beyond medical therapy, the role of endovascular approach for the management of chronic Venous Thromboembolic (VTE) disease is yet to be defined. To our knowledge, no systematic reviews or guidelines are available that provide information on how to manage this chronic condition. This paper represents the first systematic review of published reports on the use of vacuum-assisted thrombectomy (AngioVac) in treating chronic VTE disease. METHODS: A systematic review of published case-series, individual case-reports, and review articles in MEDLINE, PubMed, and Google Scholar was conducted...

OBJECTIVE: Arteriovenous (AV) fistulas are the preferred hemodialysis access for patients with end-stage renal disease, although multiple interventions are typically needed to maintain patency. When AV fistulas thrombose, however, there is debate as to whether open thrombectomy should be attempted, particularly for salvage of upper arm fistulas. This study was designed to evaluate outcomes after open thrombectomy of upper arm and forearm AV fistulas compared with AV grafts. METHODS: We identified all patients who underwent an open thrombectomy procedure for a thrombosed AV fistula or graft at a single academic medical center between January 2006 and March 2017...

OBJECTIVES: Neurologists have continually led the assessment and management of Acute Ischemic Stroke(AIS) by use of IV-rtPA, anti-platelet therapy, antihypertensives, and other pharmacologic agents. Since the advent of mechanical thrombectomy(MT) and its proven efficacy, neurovascular surgeons(NS) are playing an increasingly important role in the management and overall care of AIS. We assessed outcomes of AIS patients managed by NS, who have been traditionally managed by neurologists...

BACKGROUND: Faster time to recanalization leads to better clinical outcomes in patients treated with endovascular thrombectomy. Whether the association between time to recanalization and clinical outcomes depends on cerebral blood volume (CBV) obtained from pretreatment computed tomography (CT) perfusion (CTP) imaging was investigated. METHODS: In consecutive patients with acute ischemic stroke who achieved recanalization by endovascular thrombectomy for intracranial internal carotid artery or M1 occlusion, the effects on clinical outcome of time to recanalization and the relative CBV value (rCBV) assessed by pretreatment CTP were evaluated...

BACKGROUND: The impact of lacunar and cortical chronic ischemic lesions (CILs) on the clinical outcome of mechanical thrombectomy (MT) has been little studied. Clinical trials suggest that older patients benefit from MT. We investigated the effect of CILs on the clinical outcome of sexagenarian and older patients with acute middle cerebral artery (MCA) or distal internal carotid artery (ICA) stroke who received MT to treat large-vessel occlusion (LVO). METHODS: We prospectively collected the clinical and imaging data of 130 consecutive MT patients of which 68 met the inclusion criteria...
