BACKGROUND AND PURPOSE: Neurointerventional surgery may expose patients and physician operators to substantial amounts of ionizing radiation. Although strategies for reducing patient exposure have been explored in the medical literature, there has been relatively little published in regards to decreasing operator exposure. The purpose of this study was to evaluate the efficacy of shielding systems in reducing physician exposure in a modern neurointerventional practice. MATERIALS AND METHODS: Informed consent was obtained from operators for this Health Insurance Portability and Accountability Act-compliant, institutional review board-approved study...

BACKGROUND: Reperfusion of large vessel occlusions in acute stroke can improve patient outcomes. The purposes of this study were to assess the safety and efficacy of the Penumbra 5MAX ACE catheter for revascularization of large vessels and to compare its cost to the cost of stent retrievers. METHODS: In this retrospective, single-center case review study, data were captured on consecutive patients treated with the Penumbra 5MAX ACE as first-line therapy during an 11-month period...

Episodic care forms a payment methodology of increasing relevance to neurointerventional specialists and other providers. Episodic care payment models are currently recognized in both payment paths described by the Medicare Access and Children's Health Insurance Program (CHIP) Reauthorization Act (MACRA): the Merit-Based Incentive Payment System and Advanced Alternative Payment Models. Understanding the cost of care, as well as how such costs are shaped in the context of episodic care, will be critical to success in both of these paths...

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...

OBJECTIVE: The purpose of this study was to examine the usefulness of an emergency medical service (EMS)-requested air medical helicopter response directly to the scene for a patient with clinical evidence of an ischemic cerebrovascular accident (CVA) and transport to a regional comprehensive CVA center. METHODS: CareFlight, an air medical critical care transportation service, is based in Dayton, OH. The 3 CareFlight helicopters are geographically located and provided transport to all CVA scene patients in this study...

Background Primitive persistent trigeminal artery (PTA) is an uncommon embryologic vascular communication between the carotid and basilar arteries, which can be intimately involved by skull base tumors (SBT). Owing to its rarity, skull base surgeons should familiarize themselves with the anatomical variations of PTA to avoid catastrophic complications. Objective To appraise and summarize the available evidence of PTA involved by SBTs while advocating a standardized algorithm for the surgical planning of these patients...

Suha Akpinar, Guliz Yilmaz
Dissection of the internal carotid artery (ICA) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. Iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. In this report, a case of dissection of the ICA is reported that was caused by repetitive movement of the balloon guiding catheter during stent-assisted thrombectomy (SAT), resulting in occlusion of the ICA...

INTRODUCTION: Diffuse alveolar hemorrhage (DAH) is a very rare complication but acute and life-threatening event. Clopidogrel has generally administered for neurointerventional surgery, but there were no reports of DAH related to clopidogrel in patients undergoing neurointervention. CASE PRESENTATION: A 70-year-old male presented with DAH associated with clopidogrel after transfemoral cerebral angiography and coil embolization for cerebral aneurysm. The chest radiography showed bilateral symmetric peribronchial consolidation and bronchoscopy revealed diffuse hemorrhage on the bronchial wall at the bilateral lung...

BACKGROUND AND PURPOSE: Intra-arterial therapy (IAT) is most effective when performed rapidly after ischemic stroke onset. However, there are limited performance benchmarks in IAT and there is a scarcity of information on how to structure an effective IAT protocol and its impact on time to treatment. The objective of our study was to detail a standardized IAT protocol, and to assess its influence on time to treatment in ischemic stroke. METHODS: This was a retrospective observational study over 4 years at a comprehensive stroke center...

Subclavian steal is a relatively common vascular phenomenon usually caused by atherosclerotic disease. While symptoms are rare, arm claudication of the ipsilateral limb is most common, with paroxysmal symptoms of vertebrobasilar insufficiency (often exercise induced) being relatively uncommon. Here we present a case of brachial artery embolism during mechanical thrombectomy for basilar artery thrombosis, secondary to subclavian steal phenomenon. This atypical and potentially irreversible complication should be considered in patients with acute ischemic stroke undergoing neurointerventional management when subclavian steal is discovered angiographically...

BACKGROUND: Endovascular treatment of wide-necked aneurysms remains challenging without the use of adjunctive devices to preserve the parent artery. OBJECTIVE: To present our initial experience with a temporary bridging device, the Comaneci (Rapid Medical, Israel). The compliant remodeling mesh protects the parent artery during coil occlusion without flow arrest in the distal vasculature. Permanent dual antiplatelet therapy is not required since the device is fully removed at the end of the procedure...

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...
