Background: Postsurgical clipping aneurysm recurrences or residuals can be difficult to manage with either traditional open microsurgical approaches or endosaccular coiling. Endoluminal parent vessel reconstruction with flow diversion may be an ideal method for treating these recurrences by avoiding reoperative surgery or intraprocedural aneurysm rupture with aneurysm access. Method: We retrospectively reviewed a single-center aneurysm database identifying all anterior communicating artery (ACom) region aneurysms with recurrences after microsurgical clipping...

Ameer E Hassan, Sophie Amelot
Background and Purpose: Per the ALARA principle, reducing the dose delivered to both patients and staff must be a priority for endovascular therapists, who should monitor their own practice. We evaluated patient exposure to radiation during common neurointerventions performed with a recent flat-panel detector angiographic system and compared our results with those of recently published studies. Methods: All consecutive patients who underwent a diagnostic cerebral angiography or intervention on 2 modern flat-panel detector angiographic biplane systems (Innova IGS 630, GE Healthcare, Chalfont St Giles, UK) from February to November 2015 were retrospectively analyzed...

In many jurisdictions, an offender's remorse is considered to be a relevant factor to take into account in mitigation at sentencing. The growing philosophical interest in the use of neurointerventions in criminal justice raises an important question about such remorse-based mitigation: to what extent should technologically facilitated remorse be honoured such that it is permitted the same penal significance as standard instances of remorse? To motivate this question, we begin by sketching a tripartite account of remorse that distinguishes cognitive, affective and motivational elements of remorse...

BACKGROUND: Anterior choroidal artery (AChA) aneurysms represent a small subset of cerebral aneurysms. The Pipeline Embolization Device (PED) has been successfully applied to various aneurysms of the supraclinoid internal carotid artery (ICA). The treatment of these aneurysms requires special attention due to the eloquent territory supplied by the AChA. We report the largest and first dedicated series of flow diversion treatment of AChA aneurysms. METHODS: Four institutional neurointerventional databases were reviewed for cases of intracranial aneurysms treated with PED...

BACKGROUND: Operating rooms account for 70% of hospital waste, increasing healthcare costs and creating environmental hazards. Endovascular treatment of cerebrovascular pathologies has become prominent, and associated products highly impact the total cost of care. We investigated the costs of endovascular surgical waste at our institution. METHODS: Data from 53 consecutive endovascular procedures at the Radboud UMC Nijmegen from May to December 2016 were collected...

BACKGROUND: The safety and efficacy of the Woven EndoBridge (WEB) for the treatment of naïve intracranial aneurysms has been confirmed. PURPOSE: To analyze the safety and efficacy of the WEB in the treatment of recurrent aneurysms. METHODS: Anatomical and clinical results in consecutive patients with a recurrent aneurysm, who were treated using the WEB device in two French neurointerventional centers, were evaluated. RESULTS: Seventeen patients with 17 aneurysms were included...

REVIEW
J M Olivot
The ischemic penumbra is a transient and potentially reversible condition. Therefore, infarct progression and its counterpart penumbral salvage are highly variable and result from the interaction of 3 major factors: collateral flow, revascularization delay and success. Multimodal brain imaging now offers in clinical practice an exhaustive characterization of the acute ischemic injury: vessel site occlusion, infarction/critical hypoperfusion volume, and collateral flow. From 1995 to 2015, IV alteplase administered within 4...

BACKGROUND AND PURPOSE: The informed consent process is a major limitation for enrollment in acute stroke clinical investigations. We aim to describe the novel application of smartphone electronic informed consenting (e-Consent) in trials of cerebral thrombectomy. METHODS: The e-Consent tool consists of a secure/Health Insurance Portability and Accountability Act compliant smartphone platform based on REDCap (Research Electronic Data Capture; Vanderbilt University, TN) that uses a survey project located on a static webpage...

REVIEW
L Pierot, M Gawlitza, S Soize
Early recanalization of occluded vessels in patients with acute ischemic stroke (AIS) by either intravenous thrombolysis (IVT) or endovascular revascularization has been shown to be associated with improved clinical outcomes and reduced mortality. Since the initial report regarding endovascular treatment (EVT) of AIS in 1983, endovascular techniques have been tremendously improved, advancing from intra-arterial administration of thrombolytic drugs to stent retrievers. IVT has been evaluated in several large randomized trials and has been shown to improve clinical outcomes at 90 days if treatment was initiated within 3h of stroke onset, while its benefit at 3-4...

The rapid progression of medical imaging technology and the ability to leverage knowledge from non-invasive imaging means that Interventional Radiologists (IRs) and Interventional Neuroradiologists are optimally placed to incorporate minimally invasive interventional paradigms into clinical management to advance patient care. There is ample opportunity to radically change the management options for patients with a variety of diseases through the use of minimally invasive interventional procedures. However, this will need to be accompanied by an increased clinical role of IRs to become active partners in the clinical management of patients...

PURPOSE: The purpose of this study was to evaluate the annual trend for several neurosurgical and neurointerventional procedures (NIPs) in Korea between 2010 and 2016 by using medical claim data. MATERIALS AND METHODS: All data during the recent 7 years were collected from Bigdata Hub provided by the Health Insurance Review & Assessment Service (HIRA). Using several codes for medical practice, we estimated the number of in-patients for each practice and calculated the annual variation of each procedure...

Aim of the study A new functionality that enables vertical mobility of the lateral arm of a biplane angiographic machine is referred to as the flexible lateral isocenter. The aim of this study was to analyze the impact of the flexible lateral isocenter on the air-kerma rate under experimental conditions. Material and methods An anthropomorphic head-and-chest phantom with anteroposterior (AP) diameter of the chest varying from 22 cm to 30 cm simulated human bodies of different body constitutions. The angulation of the AP arm in the sagittal plane varied from 35 degrees to 55 degrees for each AP diameter...

BACKGROUND AND PURPOSE: Clinical outcomes in patients with acute ischemic stroke caused by large vessel occlusion depend on the speed and quality of workflows leading to mechanical thrombectomy. In the absence of universally accepted best practices for workflow, developing stroke hospitals can benefit from improved awareness of real-world workflows in effect at experienced centers. To this end, we surveyed prethrombectomy workflow practices at stroke centers throughout the United States...

BACKGROUND: Thrombectomy trials are often specifically interpreted as evidence for the effectiveness of stent retrievers. The effectiveness of other thrombectomy techniques such as aspiration thrombectomy should be validated through further investigation and review. PURPOSE: To evaluate published treatment times and clinical outcomes in patients treated with aspiration thrombectomy or ADAPT (A Direct Aspiration, First Pass Technique) for acute ischemic stroke. DATA SOURCES: A systematic literature review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...
