INTRODUCTION: Tandem occlusion resulting in acute ischemic stroke (AIS) is associated with high morbidity and mortality and a poor response to thrombolytic therapy. The use of endovascular strategies for tandem stroke cases results in an improved outcome for this subgroup of patients. We present two cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques...

INTRODUCTION: Acute basilar artery occlusion (ABAO) is an infrequent but potentially fatal cause of strokes in both adults and children, and it is usually due to vertebral artery dissection (VAD). VAD has been found to be usually a consequence of traumatic vertebral artery injury. ABAO usually presents with symptoms of acute ischemic stroke (AIS) of the posterior circulation or transient ischemic attack (TIA). It may lead to death or long-term disability if not promptly recanalized. Basilar artery recanalization in children can be achieved safely and with excellent clinical outcome using endovascular thrombectomy with the new generation self-expanding and retrievable stents...

BACKGROUND: Vessel perforation during stent retriever thrombectomy is a rare complication; typically only single instances have been reported. OBJECTIVE: To report on a series of patients whose stent retriever thrombectomy was complicated by intraprocedural vessel perforation and discuss its potential mechanisms, rescue treatment strategies, and clinical significance. METHODS: Cases with intraprocedural vessel perforation, where a stent retriever was used either as a primary treatment approach or as a part of a direct aspiration first pass technique (ADAPT), were included in the final analysis...

IMPORTANCE: Endovascular thrombectomy with second-generation devices is beneficial for patients with ischemic stroke due to intracranial large-vessel occlusions. Delineation of the association of treatment time with outcomes would help to guide implementation. OBJECTIVE: To characterize the period in which endovascular thrombectomy is associated with benefit, and the extent to which treatment delay is related to functional outcomes, mortality, and symptomatic intracranial hemorrhage...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

PURPOSE: The impact of thrombus length on recanalization in IV thrombolysis for acute intracranial artery occlusion has been well studied. Here we analyzed the influence of thrombus length on the number of thrombectomy maneuvers needed for recanalization, intraprocedural complications, recanalization success, and clinical outcome after mechanical thrombectomy. METHODS: We retrospectively analyzed angiographic and clinical data from 72 consecutive patients with acute occlusion of the M1 segment of the middle cerebral artery who were treated with mechanical thrombectomy using stent retrievers...

BACKGROUND: The clot burden score (CBS) was developed as a tool to evaluate the extent of intracranial thrombus burden in patients with anterior circulation acute ischemic stroke. CBS is based on the presence or absence of contrast opacification on CT angiography (CTA). Its value in predicting radiographic and clinical outcomes in patients given endovascular stroke therapy remains unknown. OBJECTIVE: To evaluate the relationship between CBS and outcomes after stent retriever thrombectomy in the interventional arm of the SWIFT PRIME trial...

BACKGROUND AND PURPOSE: Intra-arterial treatment by means of retrievable stents has been proven safe and effective. In MR CLEAN (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands), the choice of the type of thrombectomy device was left to the discretion of the interventionist. The aim of this study was to explore the differences in functional outcome, neurological recovery, reperfusion, extent of infarction, and adverse events according to stent type and make...

BACKGROUND: New device technology has changed the techniques used for revascularization of emergent large vessel occlusion in acute stroke. We report technical results using stent retrievers (SRs) for thrombectomy alone versus SRs used in conjunction with a new group of devices, intracranial aspiration catheters (IACs). Our aim is to demonstrate differences in procedural time and thrombectomy attempts between these two groups. METHODS: A retrospective evaluation was performed of a prospectively maintained database of 97 patients treated at a single institution for anterior circulation stroke with SRs...

The optional endovascular approach for acute ischemic stroke is unclear. The Trevo stent retriever can be used as first-line treatment for fast mechanical recanalization. The authors developed a treatment protocol for acute ischemic stroke based on the assessment of clot quality during clot removal with the Trevo. This prospective single-center study included all patients admitted for acute ischemic stroke between July 2014 and February 2015, who underwent emergency endovascular treatment. According to the protocol, the Trevo was used for first-line treatment...

Solitaire FR stent-based mechanical thrombectomy provides clinical benefit in selected patients with acute ischaemic stroke due to large vessel occlusion. A dreaded device complication that is associated with poor technical and clinical outcome is stent detachment. Retrieval of the detached stent can be technically challenging and has been attempted with variable success. The key benefit of this strategy is the lack of need to administer fibrinolytic/antiplatelet agents that can potentially be catastrophic in the setting of acute stroke...

BACKGROUND: Acute stroke care represents a challenge for decision makers. Recent randomized trials showed the benefits of endovascular therapy. Our goal was to provide a visual aid tool to guide clinicians in the decision process of endovascular intervention in patients with acute ischemic stroke. METHODS: We created visual plots (Cates' plots; representing benefits of standard of care vs. endovascular thrombectomy from the pooled analysis of five RCTs using stent retrievers...

Acute ischemic stroke remains a major global cause of death, permanent disability, and dementia. For nearly two decades, intravenous tissue plasminogen activator (tPA) has been the only recommended therapy, albeit administered within the recommended time window (i.e., <4.5h). However, intravenous tPA is associated with modest recanalization rates, with a majority of patients having poor functional outcomes despite timely administration. Endovascular therapy has recently been introduced as adjunctive management of acute ischemic stroke...

BACKGROUND AND PURPOSE: Thrombectomy, primarily with stent retrievers with or without adjunctive aspiration, provided clinical benefit across multiple prospective randomized trials. Whether this benefit is exclusive to stent retrievers is unclear. METHODS: THERAPY (The Randomized, Concurrent Controlled Trial to Assess the Penumbra System's Safety and Effectiveness in the Treatment of Acute Stroke; NCT01429350) was an international, multicenter, prospective, randomized (1:1), open label, blinded end point evaluation, concurrent controlled clinical trial of aspiration thrombectomy after intravenous alteplase (IAT) administration compared with intravenous-alteplase alone in patients with large vessel ischemic stroke because of a thrombus length of ≥8 mm...

This review summarizes the modern early diagnosis and acute phase treatment of acute stroke. The guidelines for treatment of acute ischemic stroke underwent major changes in 2015 and endovascular therapy (catheter-based mechanical thrombectomy with a stent retriever) became the class IA indication for patients presenting within less than 6h from symptom onset who have proven occlusion of large intracerebral artery in anterior circulation. Acute stroke care organization should enable to perform effective revascularization therapy as soon as possible after the initial brain imaging whenever this examination provides indication for the procedure...

BACKGROUND: This is the first clinical report on experience in the use of the Gore embolic filter in carotid interventions. It was designed as a guidewire and embolic protection system in carotid, peripheral, and coronary interventions. The ability to capture debris is driven by the frame of the filter, which is designed to improve vessel wall apposition and allows a short landing zone. METHODS: We report the results of the first 20 consecutive patients undergoing carotid artery stenting using the Gore embolic filter in our institution...

BACKGROUND AND PURPOSE: Acute ischemic stroke (AIS) in the elderly encompasses approximately one-third of all AIS cases. Outcome data have been for the most part discouraging in this population. We aim to evaluate the outcomes in a large contemporary series of elderly patients treated with thrombectomy. METHODS: Retrospective analysis of a single-center endovascular database for consecutive elderly (≥80 years) patients treated for anterior circulation large vessel occlusion AIS between September 2010 and April 2015...
