BACKGROUND: Endovascular treatment of aneurysms with coils is among the most frequent treatments in interventional neuroradiology, and represents an important expense. Each manufacturer has created several types of coils, with prices varying among brands and coil types. The objective of this study was to assess the impact of cost awareness of the exact price of each coil by the operating physician on the total cost of aneurysm coiling. MATERIALS AND METHODS: This was a comparative study conducted over 1 year in a single tertiary care center...

Acute management of ischemic stroke is a burning topic in 2017 since stroke represents the leading cause of acquired handicap in adults. Over the last past years, major improvement took place, especially with the demonstration of the efficacy of mechanical thrombectomy, thus needing to better organize care pathways, and optimize access to neurologists and interventional neuroradiology platforms. Intensive care stroke units remain the pivotal place of patients' management. A multidisciplinary coordination is required, with continuous teaching of all the actors involved in stroke management, so as to increase the number of patients who could benefit from available active treatments...

We report the case of a 68-year-old male with right eye vision loss secondary to a compressive optic neuropathy from Waldenstrom macroglobulinaemia relapse in both cavernous sinuses. Central nervous system involvement is extremely uncommon in lymphoplasmacytic lymphoma. Known as Bing-Neel syndrome, this has not been previously reported to present simultaneously in bilateral cavernous sinuses. We discuss the pathophysiology, diagnostic and neuroradiological features of Bing-Neel syndrome. In this case, there was marked clinical and radiological response to chemotherapy...

Etiopathogenesis and physiopathology of gliomas are largely unknown. Recently, many authors have proved a strict correlation between the velocity of diametric expansion (VDE) on the Magnetic Resonance Imaging (MRI) and the biological behavior of these tumors, especially in Low Grade Gliomas (LGGs). Unfortunately, natural history of High Grade Gliomas (HGGs) has not been well clarified because of its fast progression, late diagnoses and early surgical intervention. We describe, for the first time to our knowledge, the case of asymptomatic patient with an incidentally discovered de novo HGG with a total of 17 months of follow-up...

BACKGROUND AND PURPOSE: We have found DSA-Dynavision with multiplanar reconstruction very helpful in understanding the complex anatomy and planning of treatment of carotico-cavernous fistulas. The purpose of our study was to examine whether using DSA-Dynavision in pretreatment planning results in better outcome after endovascular treatment of dural arterio-venous fistulas (dAVFs). METHODS: Patients with dAVF treated with endovascular embolization were retrospectively identified from our interventional neuroradiology database...

BACKGROUND AND PURPOSE: Although a stroke from atherosclerosis in the basilar artery (BA) often presents with mild initial stroke severity, it has heterogeneous clinical courses. We investigated the efficacy of digital subtraction angiography (DSA)-based collateral perfusion evaluation in association with long-term outcomes of medically treated symptomatic basilar artery stenosis. METHODS: From a registry database of all consecutive patients with stroke, we included 98 medically treated patients (due to mild initial stroke severity) [National Institute of Health Stroke Scale (NIHSS) scores ≤ 4; symptomatic basilar artery stenosis, 70-99%] with available initial diagnostic DSA...

Aberrant regeneration of the third nerve occurs as a result of synkinetic 'miswiring' of the third nerve following its injury, such as in third cranial nerve palsy due to tumor, trauma, or aneurysm. The case presented is an elderly woman with new vertical diplopia, which led to a diagnosis of a third cranial nerve palsy, thought to be caused by a 5 mm blister aneurysm of the posterior communicating artery. However, neuro-ophthalmological evaluation diagnosed aberrant regeneration of the third nerve, with the cause of her new vertical diplopia being an ipsilateral fourth nerve palsy...

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...

Although proof-based medicine has generated much valid evidence for the drawing up of guidelines and recommendations for best clinical practice in symptomatic and asymptomatic carotid stenosis, whether and when it is better to employ endarterectomy or stenting as the intervention of choice still remain matters of debate. Moreover, guidelines have been targeted up to now to the 'representative' patient, as resulting from the statistical analyses of the studies conducted on the safety and efficacy of both interventions as well as on medical therapy alone...

Despite the continuing emphasis on the importance of clinical skills, these skills do not appear to be improving and may actually be declining. The 'unity of knowledge and action' is a medicine directed precisely at this disease. The 'unity of knowledge and action' helps to learn from failure and successes, learn from mistakes of predecessors and institute a behaviour that prevents repetition of these mistakes.

REVIEW
Joachim Berkefeld, Marlies Wagner, Richard du Mesnil
After a period of stagnation due to negative results of randomized trials for patients with symptomatic stenosis, the relevance of carotid artery stenting (CAS) is increasing again. CAS has become an important and evidence-based part of interventional stroke treatment. Our ability to manage acute recanalization of carotid occlusions and other niche indications properly led some skeptical neurologists to trust in carotid intervention for elective cases as well. The evolution of CAS from initial euphoria to more realistic views under consideration of trial results and guidelines is reviewed...
