BACKGROUND: Carotid artery stenting (CAS) with proximal occlusion effectively prevent distal cerebral embolism by flow arrest at internal carotid artery (ICA); however, the method can expose antegrade flow at ICA due to incomplete flow arrest. The aim of this study was to identify predictors of antegrade flow during CAS with proximal protection. METHODS: We retrospectively analyzed clinical and angiographic data among 143 lesions treated with CAS with proximal protection by occluding the common carotid artery (CCA) and external carotid artery (ECA)...

Internal carotid artery dissection is one of the possible causes of stroke in young adults. The effectiveness of medical therapy alone is often limited and endovascular strategy should be considered, particularly in the presence of persisting neurological symptoms. Currently, there is no general consensus on the most appropriate therapeutic strategy to follow in symptomatic carotid artery dissection. We here report a case of symptomatic carotid artery dissection treated with an endovascular approach, and we review the recent literature regarding this therapeutic strategy...

INTRODUCTION: Mechanical thrombectomy (MT) has been widely accepted as a safe and effective treatment for acute ischemic stroke (AIS). Development of stent retriever devices has been intensively developed over the past two decades. In this study, we compared the effectiveness and safety of a new thrombectomy device with Solitaire FR for the treatment of AIS models. METHODS: Mechanical performance of stent retrievers was tested in vitro. Thrombin-induced thrombus was pre-injected into the right distal external carotid-maxillary artery in 18 dogs to create an acute thrombus occlusion model, and these animals were divided into a Tonbridge group (n=9, with Tonbridge stent Tonbridge Medical Technology) and a Solitaire group as control (n=9, with Solitaire stent, ev3 Neurovascular)...

BACKGROUND: Right-sided subclavian artery stenosis is a rare cerebrovascular disease involving the upper extremities. Considering an endovascular approach for its management requires increased endovascular and catheterization skills, when compared to the left side, due to the close approximation of the right subclavian artery origin, vertebral and common carotid arteries. METHODS: Three patients suffering from proximal right sided subclavian artery stenosis were treated in our center through primary stenting...

BACKGROUND: Atrial fibrillation (AF) increases risk of stroke 5-fold. Carotid artery disease (CD) also augments the risk of stroke, yet there are limited data about the interplay of these 2 diseases and clinical outcomes in patients with comorbid AF and CD. HYPOTHESIS: Among patients with both AF and CD, use of rivaroxaban when compared with warfarin is associated with a lower risk of stroke. METHODS: This post hoc analysis from ROCKET AF aimed to determine absolute rates of stroke/systemic embolism (SE) and bleeding, and the efficacy and safety of rivaroxaban compared with warfarin in patients with AF and CD (defined as history of carotid occlusive disease or carotid revascularization [endarterectomy and/or stenting])...

PURPOSE: Endovascular treatment of bifurcation aneurysms is difficult and complicated because arterial branches may arise from the aneurysmal neck. We treat these cases with complex techniques such as Y or T stenting. In this report, we deployed one Neuroform EZ stent using the intentional herniation technique for the preservation of arterial branches. CASE PRESENTATION: A 78-year-old female presented with two unruptured aneurysms. One was an 8 mm aneurysm located at the bifurcation of the internal carotid artery and the posterior communicating artery (PcomA)...

Background In cases of acute ischemic stroke, manual aspiration of the thrombus is commonly performed with a balloon guiding catheter placed in the cervical segment of the internal carotid artery (ICA). However, most manual aspirations using a balloon guiding catheter are combined with inner catheters, as in the direct aspiration first pass technique (ADAPT). We experienced some cases of acute ischemic stroke with proximal ICA occlusion due to cardiogenic thrombus where we obtained sufficient recanalization by simple manual aspiration from inflated Optimo 9F balloon catheters (Tokai Medical Products, Japan) placed in the origin of the cervical segment of the ICA without any inner catheter or stent retriever...
