Intracranial endovascular interventions provide effective and minimally invasive treatment of a broad spectrum of diseases. This area of expertise has continued to gain both wider application and greater depth as new and better techniques are developed and as landmark clinical studies are performed to guide their use. Some of the greatest advances since the last American Heart Association scientific statement on this topic have been made in the treatment of ischemic stroke from large intracranial vessel occlusion, with more effective devices and large randomized clinical trials showing striking therapeutic benefit...

The field of neurointerventional radiology (NIR) therapy, including acute ischemic stroke intervention, endovascular intracranial aneurysm management, and treatment of intra- and extracranial large-vessel disease, has evolved over the past 18 years. To support this specialized advanced care requires nursing standards of care for staff to provide direct patient care in NIR suites and intensive management of this high-risk patient population. The intent of this paper is to provide a complementary document for the Stroke Interventional Laboratory Consensus (SILC) statement that will specifically address the nursing standards of care for patients in an NIR suite...

OBJECTIVE: An onsite access to neurointerventional radiology (NIR) may be useful for managing patients with aneurysmal subarachnoid hemorrhage (aSAH) after the aneurysm-securing procedure. We aimed to assess the association between neurological outcomes related to aSAH and onsite access to NIR service. METHODS: This was a sequential period study of 47 patients with aSAH admitted consecutively during the pre-NIR period (January 2010 to June 2012) compared with 81 patients with aSAH admitted consecutively during the post-NIR period (January 2013 to June 2015) at an academic tertiary referral intensive care unit (ICU)...

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...

BACKGROUND AND PURPOSE: Neuroendovascular surgery is a medical subspecialty that uses minimally invasive catheter-based technology and radiological imaging to diagnose and treat diseases of the central nervous system, head, neck, spine, and their vasculature. To perform these procedures, the practitioner needs an extensive knowledge of the anatomy of the nervous system, vasculature, and pathological conditions that affect their physiology. A working knowledge of radiation biology and safety is essential...

1. Parallels in the evolution of x-ray angiographic systems and devices used for minimally invasive endovascular therapy Charles Strother - DSA, invented by Dr. Charles Mistretta at UW-Madison, was the technology which enabled the development of minimally invasive endovascular procedures. As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures. Along with development of catheters, embolic materials, pushable coils and the GDC coils there was simultaneous development and improvement of 2D DSA image quality and the introduction of 3D DSA...

BACKGROUND AND PURPOSE: Thrombolysis in cerebral infarction (TICI) with 2b/3 (>50% of occluded territory/complete reperfusion) has been regarded as a successful angiographic outcome. To account for near-perfect angiographic results, the category TICI 2c (near-complete reperfusion) has been introduced. As the degree of inter-rater reliability for TICI with 2c category remains poorly studied, we strived to evaluate the agreement among stroke-treating specialists. METHODS: All consecutive patients, who underwent stent-retriever thrombectomy for acute ischemic stroke in the period between January 2014 and April 2016 at the Department of Neurointerventional Radiology, were analyzed...

Neurovascular emergencies, consisting of acute ischemic stroke, non-traumatic aneurysmal subarachnoid hemorrhage, arteriovenous malformation, dural arteriovenous fistula, and carotid- cavernous fistula, can have an acute presentation to the emergency department. Radiologists should have an understanding of these processes and their imaging findings in order to provide a prompt and accurate diagnosis. Neurointerventional radiology plays a critical role in providing additional diagnostic information and potentially curative treatment...

Brain arteriovenous malformations are frequently associated with the presence of intracranial aneurysms at a higher-than-expected incidence based on the frequency of each lesion individually. The identification of intracranial aneurysms in association with AVMs has increased due to improvement in diagnostic techniques, particularly 3D and superselective conventional angiography. Intracranial aneurysms may confer a higher risk of hemorrhage at presentation and of rehemorrhage in patients with AVMs and therefore may be associated with a more unfavorable natural history...

Ischemic stroke following cardiac surgery is one of the devastating complications that surgeons may encounter, and may lead to serious disabilities for the patient. The clinical course of such a complication may be prolonged if it is not treated properly. Making a quick decision when choosing a revascularization method is very helpful in this matter. Effective treatment options are usually limited. Neurointerventional maneuvers have recently emerged as a possible therapeutic modality in this field. We present the case of a 52-year-old woman who had open heart surgery in Queen Alia Heart Institute, Jordan, to replace a severely stenotic rheumatic mitral valve and repair a leaking tricuspid valve...

BACKGROUND AND PURPOSE: Eye lenses are among the most sensitive organs to x-ray radiation and may be considered at risk during neurointerventional radiology procedures. The threshold dose to produce eye lens opacities has been recently reduced to 500 mGy by the International Commission on Radiologic Protection. In this article, the authors investigated the radiation doses delivered to patients' eyes during interventional neuroradiology procedures at a university hospital. MATERIALS AND METHODS: Small optically stimulated luminescence dosimeters were located over patients' eyes during 5 diagnostic and 31 therapeutic procedures performed in a biplane x-ray system...

OBJECT The development of neurointerventional treatments of central nervous system disorders has resulted in the need for adequate training environments for novice interventionalists. Virtual simulators offer anatomical definition but lack adequate tactile feedback. Animal models, which provide more lifelike training, require an appropriate infrastructure base. The authors describe a training model for neurointerventional procedures using the human placenta (HP), which affords haptic training with significantly fewer resource requirements, and discuss its validation...
