The safety and efficacy of emergency carotid artery stenting (CAS) for patients with acute ischemic stroke resulting from internal carotid artery stenosis are not established. In this retrospective study, we evaluated outcomes for CAS performed within 2 weeks of acute ischemic stroke for 16 patients treated between December 2009 and February 2014. Cases of internal carotid artery occlusion, internal carotid dissection, or intracranial major arterial trunk occlusion were excluded. Five patients were treated with CAS during the hyperacute phase (within 24 h of stroke onset), three in the advanced phase (within 24 h of stroke-in-evolution after admission), and eight in the acute phase (24 h to 2 weeks after onset)...

BACKGROUND: Little is known regarding the endovascular management of acute ischemic stroke (AIS) related to carotid artery dissection (CAD). OBJECTIVE: To report our interventional experience in AIS from CAD and to compare it with conservative treatment of CAD with intravenous thrombolysis (IVT) via systematic review. METHODS: Retrospective analysis of consecutive high-grade steno-occlusive CAD with National Institutes of Health Stroke Scale (NIHSS) >5 and ≤12 hours of last seen normal from 2 tertiary centers...

Extracranial carotid artery occlusion or high-grade stenosis with concomitant intracranial embolism causes severe ischemic stroke and shows poor response rates to intravenous thrombolysis (IVT). Endovascular therapy (EVT) utilizing thrombectomy assisted by carotid stenting was long considered risky because of procedural complexities and necessity of potent platelet inhibition-in particular following IVT. This study assesses the benefits and harms of thrombectomy assisted by carotid stenting and identifies factors associated with clinical outcome and procedural complications...

PURPOSE: Due to high thrombus load, acute stroke patients with tandem obstructions of the extra- and intracranial carotid arteries or the middle cerebral artery show a very limited response to systemic thrombolysis. Interventional treatment with mechanical thrombectomy-often in combination with acute stenting of underlying atherosclerotic stenosis or dissection-is increasingly used. It has been shown that such complex interventions are technically feasible. The lack of optimal management strategies and clinical data encouraged us to review our acute stroke interventions in patient with anterior circulation tandem lesions to determine lesion patterns, interventional approaches, and angiographic or clinical outcomes...

BACKGROUND: The degree of stenosis of carotid arteries is recognized as an important risk factor for ischemic stroke. However, high-grade stenosis does not always cause cerebrovascular events, whereas low- to moderate-grade stenosis may often cause strokes. It has been reported that there is an association between carotid intraplaque hemorrhage (IPH) and new brain ischemic events. CASE PRESENTATION: We present three patients with asymptomatic moderate carotid artery stenosis and carotid IPH who underwent both neurological and MRI at baseline and after at least 1 year's follow-up...

PURPOSE: Acute major stroke with high-grade stenosis or occlusion of the extracranial internal carotid artery (ICA) and additional intracranial large artery occlusion is increasingly treated with a mechanical endovascular approach by extracranial stenting and intracranial thrombectomy due to poor response to systemic thrombolysis with recombinant tissue plasminogen activator (rtPA). This article presents a single centre cohort of this challenging subtype of stroke, describing the technical procedure and analysing the angiographic and clinical outcome...

INTRODUCTION: Blood blister-like aneurysms (BBAs) are fragile and difficult to treat. Routine surgical and endovascular treatment methods, such as clipping, clip wrapping, primary coiling, or stent assisted coiling, have relatively high morbidity and mortality rates. In this study, we report clinical and angiographic results for treatment of ruptured BBAs using flow diverter stents. METHODS: We retrospectively reviewed patients who presented with subarachnoid hemorrhages caused by rupture of BBAs and who were treated using flow diverter stents at three neurointervention centers between January 2009 and January 2013...

INTRODUCTION: Acute stroke from occlusion of the intracranial internal carotid artery (ICA) is associated with a poor clinical outcome despite a thrombolytic treatment. The purpose of this study was to evaluate the outcome of mechanical thrombectomy using the Solitaire stent for the treatment of acute stroke patients with intracranial ICA occlusion. METHODS: A total of 104 consecutive patients with acute stroke were treated with mechanical thrombectomy using the Solitaire stent as a first-line intra-arterial treatment...

The incidence of first stroke in Germany is about 200.000, most of which are ischemic. The benefit of stroke unit treatment and systemic thrombolysis has been shown in large randomized trials. Diagnostic work-up besides neurologic examination includes cerebral imaging by CT or MR imaging including angiography, ultrasound of brain supplying arteries, ECG and Holter ECG and - if indicated - transesophageal echocardiography. Aspirin is the cornerstone of early secondary prevention in the acute phase, thereafter secondary prevention is determined by stroke etiology...

Treatment of acute stroke is time-dependent, with the best outcomes resulting from the earliest interventions. However, for patients with acute ischemic stroke due to a high-grade stenosis of the internal carotid artery, despite maximal medical treatment, an effective intervention to improve their neurologic symptoms and clinical outcome has not yet been established. There are two major concerns: first, cerebral revascularization in the acute stage remains challenging because of the possibility that hemorrhagic infarction or hyperperfusion syndrome will occur after revascularization; second, alarms about carotid artery stenting in patients with acute symptoms are related to the fact that, while with carotid endarterectomy the plaque is completely removed, after stenting it is only remodelled and its stabilization is essential to avoid embolic events during the procedure and in the post-operative period...

BACKGROUND: The purpose of this study was to evaluate the efficacy of multimodal endovascular treatment (EVT) other than clot retrieval for acute large-vessel occlusion (LVO). METHODS: Fifty-six consecutive patients with a median National Institutes of Health Stroke Scale (NIHSS) score of 15 were included this study. In all cases, intravenous administration of recombinant tissue plasminogen activator had failed (n = 23) or was contraindicated (n = 33). The modes of EVT performed included intra-arterial thrombolysis, mechanical clot disruption including balloon angioplasty, and stent placement...

INTRODUCTION: Acute carotid artery occlusion carries a high morbidity and mortality. Acute angioplasty and stenting is a feasible option with little known about the long term outcome. Limiting factor for this approach is hyperperfusion syndrome or hemorrhagic infarction. Spontaneous early or late recanalization for extracranial vessel is in the range of 5% -30%, with no well defined clinical outcome data. We describe a case of spontaneous common carotid recanalization. CASE REPORT: An 88 year old man presented with right sided weakness, global aphasia and visual field loss and was discovered to have common carotid occlusion at its origin...

BACKGROUND AND PURPOSE: The use of cerebral protection during CAS is an extended practice. Paradoxically it is open to question because it can lead to potential embolic complications. The aim of this study was to evaluate the safety and efficacy of CASWPD in patients with severe symptomatic carotid artery stenosis. MATERIALS AND METHODS: A prospective study was performed including 210 consecutive patients (201 symptomatic and 9 asymptomatic) with carotid artery stenosis >70%...

BACKGROUND: A study was undertaken to investigate the feasibility, safety and effectiveness of emergency carotid artery stenting (eCAS) for a high-grade carotid stenosis with intraluminal thrombus (ILT) with or without proximal flow control (PFC). METHODS: Patients with acute ischemic stroke included in the analysis were those who were admitted between 2001 and 2010 with serious neurological symptoms, without a large high-intensity area of diffusion-weighted images and who underwent eCAS for a high-grade carotid stenosis with ILT...

OBJECTIVES: The purpose of this study is to demonstrate the technical success of carotid artery stenting in acute extracranial internal carotid artery (ICA) occlusion as well as the benefit in clinical outcome. BACKGROUND: Stroke caused by acute occlusion of the ICA is associated with a significant level of morbidity and mortality. For this type of lesion, treatment with standard intravenous thrombolysis alone leads to a good clinical outcome in only 17% of the cases, with a death rate as high as 55%...

Jaw claudication could result from external carotid artery (ECA) occlusive disease. Carotid artery stenting (CAS) has been shown to worsen the disease in the ECA. This could potentially worsen the symptoms in patients with pre-existing jaw claudication undergoing CAS. Meanwhile, ECA endarterectomy is routinely done during internal carotid artery endarterectomy (CEA). This has been shown to alleviate jaw claudication symptoms. We report a case of a high-risk patient for CEA who presented with symptomatic carotid disease as well as bilateral jaw claudication...

Superficial vein thrombosis (SVT) occurs at least as frequent as deep vein thrombosis (DVT), and shares common risk factors with venous thromboembolism. The CALISTO trial was the first to provide specific recommendations for the pharmacologic treatment of SVT. Before treatment is initiated, an accompanying DVT must be excluded and the proximal extension of the SVT assessed. If the proximal extension of the thrombus is closer than 3 cm towards the deep vein system, it should be treated like DVT. Under certain conditions treatment with fondaparinux is indicated in acute symptomatic SVT...

Stroke is the third most common cause of mortality, and carotid artery stenosis causes 8% to 29% of all ischemic strokes. Best medical treatment forms the basis of carotid stenosis treatment, and carotid endarterectomy (CEA) has an additional beneficial effect in high-grade stenosis. Carotid angioplasty and stenting (CAS) has challenged CEA as a primary carotid intervention. At present, CEA remains the gold standard, but in the future, CAS techniques will evolve and might become beneficial for subgroups of patients with carotid stenosis...

The stenting of carotid dissection has been described for the prevention of cerebral ischemia in patients who remain symptomatic despite therapeutic anticoagulation, in those who present contraindications for anticoagulation therapy, or who present a local or extensive stenosis, with an associated pseudoaneurysm. We here report a case associating a high clinical grade aneurysmal rupture with a bilateral extracranial carotid dissection. Because of the haemodynamic risk due to the acute bilateral stenosis-induced dissection and the occurrence of a vasospasm, the carotid dissections were treated with self-expendable stents...

Patients with cerebral ischemia as a result of acute cervical internal carotid artery occlusion are generally considered to have a poor prognosis. Despite maximal medical treatment, a better treatment for patients with acute ischemic stroke who present with serious neurologic symptoms on admission or continue to deteriorate neurologically due to a total occlusion, a dissection or a high-grade stenosis of the internal carotid artery is required. An effective intervention to improve their neurologic symptoms and clinical outcome has not yet been established and represents a challenging and complex problem...
