OBJECTIVEThe aim of this paper was assess the efficacy and safety of using the MynxGrip arterial closure device in pediatric neuroendovascular procedures where the use of closure devices remains off-label despite their validation and widespread use in adults.METHODSA retrospective review of all pediatric patients who underwent diagnostic or interventional neuroendovascular procedures at the authors’ institution was performed. MynxGrip use was predicated by an adequate depth of subcutaneous tissue and common femoral artery (CFA) diameter. Patients remained on supine bedrest for 2 hours after diagnostic procedures and for 3 hours after therapeutic procedures. Patient demographics, procedural details, hemostasis status, and complications were recorded.RESULTSOver 36 months, 83 MynxGrip devices were deployed in 53 patients (23 male and 30 female patients; mean age 14 years) who underwent neuroendovascular procedures. The right-side CFA was the main point of access for most procedures. The mean CFA diameter was 6.24 mm and ranged from 4 mm to 8.5 mm. Diagnostic angiography comprised 46% of the procedures. A single device failure occurred without any sequelae; the device was extracted, and hemostasis was achieved by manual compression with the placement of a Safeguard compression device. No other immediate or delayed major complications were recorded.CONCLUSIONSMynxGrip can be used safely in the pediatric population for effective hemostasis and has the advantage of earlier mobilization.

This retrospective study evaluated the safety and feasibility of a new arterial femoral access closure device in neurointerventional procedures. The study includes all consecutive adult patients who underwent femoral arteriotomy closure with the MynxGrip™ closure device after Neurointerventional procedures performed between June and December 2012. All patients had a follow-up color Doppler ultrasound (US) within 48 hours after the procedure, which was independently interpreted by two experienced radiologists to evaluate for access site complications. Device success/failure, sheath size, ambulation time, and periprocedural complications were recorded. Fifty-five closure devices were deployed in 53 patients. There were 23 (43%) males and 30 (57%) females; age ranged from 22 to 84 years (mean: 52.1 years). Thirty of the 55 procedures (55%) were therapeutic and 25 were diagnostic interventions (45%). Sheath sizes used were 5F in 35 procedures (64%) and 6F in 20 procedures (36%). The right femoral artery was accessed in 51 procedures (93%) and the left in four procedures (7%). There was only one (1.8%) minor periprocedural complication (small hematoma). Hemostasis was successful in 51 of the 55 procedures (93%) with subsequent early ambulation. No device-induced complications associated with serious clinical sequelae were reported. In our small series, the MynxGrip™ femoral access closure device provided a safe and feasible way of closing the femoral artery puncture site after neurointerventional procedures with low minor complication rates and no major complications. Further large prospective randomized trials are necessary to evaluate the efficacy of the device.

The use of intracranial stents in neurointerventional surgery has been practiced for decades. However, the spectrum of treatable pathology, available devices, and clinical adoption of intracranial stents has exploded in recent years. Diagnostic neuroradiologists play a critical role in the evaluation of these devices after deployment, yet may not be familiar with state-of-the-art intracranial stent devices and indications. This review provides an overview of intracranial stents for cerebrovascular disease, with 3 chief learning objectives: 1) to understand the basic principles of stent design, biomechanics, and deployment, and the resulting influence on cerebrovascular hemodynamics; 2) to be familiar with the spectrum of intracranial pathology amenable to endovascular stent placement; and 3) to recognize the radiographic appearance of successful intracranial stent deployment and intracranial stent‐related complications.Learning Objective: Recognize the key principles of design (form), current indications (function), and potential complications of intracranial stents used in neurointerventional surgery

Endovascular thrombectomy is now the standard of care for large vessel occlusion stroke. The aim is to achieve rapid and complete recanalisation while avoiding complications. Apart from the conventional complications of neurointerventional procedures, mechanical thrombectomy has its unique set of complications, inherent to the disease pathophysiology. We describe an unusual complication of catheter fracture and subsequent distal embolisation into the cerebral vasculature, which was noticed 24 hours after the procedure. Due to a lack of clinical consequences, we decided to manage it conservatively. The patient died within the following few days from respiratory complications unrelated to the stroke or the endovascular thrombectomy procedure. Consequently, we were able to retrieve the fractured segment and carry out histopathological analysis, which helped us to identify exactly its origin from the guide catheter. We believe that systematic reporting and database compilation of such device-related complications will aid in the design and development of neurointerventional devices in the future.

AbstractBACKGROUNDDespite several studies analyzing the safety of transradial access (TRA) for neurointervention compared to transfemoral approach (TFA), neurointerventionalists are apprehensive about implementing TRA. From our positive institutional experience, we now utilize TRA first line for a majority of our cases. Here, we present our single-institution experience.OBJECTIVETo determine safety and feasibility of TRA for neurointervention.METHODSThrough retrospective review of patients receiving TRA for anterior and posterior circulation cerebrovascular interventions at our institution between December 2015 and January 2018, we present our experience regarding this transition, while focusing on technique, complications, feasibility, indications, and limitations.RESULTSOne hundred five procedures were performed on 92 patients (anterior circulation: 77%; posterior circulation: 23%). Radial artery access was achieved in all patients. Twenty-nine cases constituted mechanical thrombectomy, 33 cases represented intracranial aneurysms treatments, and 33 cases included interventions like angioplasty, balloon test occlusion, chemotherapy delivery, and thrombolysis. TRA was used as second-line access to TFA in 5 instances due to aortic arch anomalies and atherosclerotic disease. Minor access-site complications were seen in 2.85% of patients. Ten procedures (9.0%) could not be completed with TRA, with crossover to TFA occurring in 7 cases.CONCLUSIONTRA is safe and feasible for the majority of neurointerventional procedures and provides decreased risk of major access-site complications compared to TFA. Perceived limitations of TRA can likely be eliminated via operator experience and engineering ingenuity; thus, there is a role for TRA for neurointervention, especially in patients with increased risk of access-site complications from TFA.

Background: Concomitant acute ischemic stroke (AIS) caused by large vessel occlusion (LVO), and acute upper extremity arterial occlusion causing upper limb ischemia (ULI) is a rarely observed coincidence. The first-line treatment for AIS is mechanical thrombectomy (MT), with or without additional intravenous thrombolysis, while there are different pharmacological, surgical and endovascular treatment options for an acute occlusion of the UL arteries. Here, we describe the practicability, efficacy and safety of neurointerventional devices and techniques for MT of upper extremity arterial occlusions. Materials and Methods: A retrospective analysis of prospectively collected patient databases from four neurovascular centers was performed. Clinical and imaging data, as well as procedural parameters, were assessed. Results: Seven out of 6138 patients (incidence: 0.11%) presenting with an AIS due to the occlusion of craniocervical arteries requiring MT and a concomitant occlusion of the brachial (4/7), axillary (2/7), or ulnar (1/7) artery causing acute ULI were identified. Craniocervical MT was technically successful in all cases. Subsequent MT of the upper limb was performed using neurointerventional thrombectomy techniques, most frequently stent retriever thrombectomy (in 4/7 cases) and direct aspiration (in 7/7 cases). MT achieved successful recanalization in 6/7 cases, and the UL completely recovered in all six cases. In one case, recanalization was not successful, and the patient still had a marginally threatened extremity after the procedure, which improved after pharmacological therapy. Conclusion: In the rare case of AIS requiring MT and concomitant acute upper extremity arterial occlusion, MT of the UL arteries using neurointerventional devices and techniques is practical, effective, and safe.

BackgroundDespite the recent increase in the number of publications on diagnostic cerebral angiograms using transradial access (TRA), there have been relatively few regarding TRA for neurointerventional cases. Questions of feasibility and safety may still exist among physicians considering TRA for neurointerventional procedures.MethodsA systematic literature review was performed following PRISMA guidelines. Three online databases (MedLine via PubMed, Scopus and Embase) were searched for articles published between January 2000 and December 2019. Search terms included “Transradial access”, “Radial Access”, “Radial artery” AND “Neurointerventions". The reference lists of selected articles and pertinent available non-systematic analysis were reviewed for other potential citations. Primary outcomes measured were access site complications and crossover rates.ResultsTwenty-one studies (n=1342 patients) were included in this review. Two of the studies were prospective while the remaining 19 were retrospective. Six studies (n=616 patients) included TRA carotid stenting only. The rest of the studies included treatment for cerebral aneurysms (n=423), mechanical thrombectomy (n=127), tumor embolization (n=22), and other indications (n=154) such as angioplasty and stenting for vertebrobasilar stenosis, balloon test occlusion, embolization of dural arteriovenous fistula and arteriovenous malformation, chemotherapeutic drug delivery, intra-arterial thrombolysis, and arterial access during a venous stenting procedure. Two (0.15%) major complications and 37 (2.75%) minor complications were reported. Sixty-four (4.77%) patients crossed over to transfemoral access for completion of the procedure. Seven (0.52%) patients crossed over due to access failure and 57 (4.24%) patients crossed over to TFA due to inability to cannulate the target vessel.ConclusionThis systematic review demonstrates that TRA has a relatively low rate of access site complications and crossovers. With increasing familiarity, development of TRA-specific neuroendovascular devices, and the continued reports of its success in the literature, TRA is expected to become more widely used by neurointerventionalists.

This volume makes a contribution to the field of neurolaw by investigating issues raised by the development, use, and regulation of neurointerventions. The broad range of topics covered in these chapters reflects neurolaw’s growing social import, and its rapid expansion as an academic field of inquiry. Some authors investigate the criminal justice system’s use of neurointerventions to make accused defendants fit for trial, to help reform convicted offenders, or to make condemned inmates sane enough for execution, while others interrogate the use, regulation, and social impact of cognitive enhancement medications and devices. Issues raised by neurointervention-based gay conversion “therapy”, the efficacy and safety of specific neurointervention methods, the legitimacy of their use and regulation, and their implications for authenticity, identity, and responsibility are among the other topics investigated. The focus on neurointerventions also highlights tacit assumptions about human nature that have important implications for jurisprudence. For all we know, at present such things as people’s capacity to feel pain, their sexuality, and the dictates of their conscience, are unalterable. But neurointerventions could hypothetically turn such constants into variables. The increasing malleability of human nature means that analytic jurisprudential claims (true in virtue of meanings of jurisprudential concepts) must be distinguished from synthetic jurisprudential claims (contingent on what humans are actually like). Looking at the law through the lens of neurointerventions thus also highlights the growing need for a new distinction—between analytic jurisprudence and synthetic jurisprudence—to tackle issues that increasingly malleable humans will face when they encounter novel opportunities and challenges.

Although femoral artery catheterization has been the mainstay of arterial access for cerebral angiography, there has been a recent increase in the use of transradial access among neurointerventionalists. Despite its widespread use among interventional cardiologists, there is a paucity of evidence for its use in the neurosurgical literature. With the constant evolution of device technology and the need of multimodal treatments for complex neurovascular pathologies, most neurointerventionalists resort to femoral artery access because of the vessel’s larger diameter and having been trained with that approach. However, transradial access confers a number of benefits, most notably lower risk of vascular complications, shorter recovery, and increased patient satisfaction and cost reduction. Femoral artery catheterization requires patients to tolerate a painful and uncomfortable procedure, with associated potential complications such as pseudo-aneurysm formation, retroperitoneal hematoma, and artery occlusion. Compared with groin access, radial artery catheterization has been shown to confer a lower risk of local neurovascular complications and improved quality-of-life metrics. This book is the first of its kind, detailing step by step all the technical nuances of the transradial approach in the neurointerventional world, from diagnostic cerebral angiograms to neurointerventional procedures. This is the perfect book for physicians who decided to make the transition of their practice to transradial.

The world’s first clinical trial using advisory brain implant operated by artificial intelligence (AI) has been completed with significant success. The tested devices predict a specific neuronal event (epileptic seizure), allowing people implanted with the device to be forewarned and to take steps to reduce or avoid the impact of the event. In principle, these kinds of artificially intelligent devices could be used to predict other neuronal events and allow those implanted with the device to take precautionary steps or to automate drug delivery so as to avoid unwanted outcomes. This chapter examines moral issues arising from the hypothetical situation where such devices controlled by AI are used to ensure that convicted criminal offenders are safe for release into society. We distinguish two types of predictive technologies controlled by AI: advisory systems and automated therapeutic response systems. The purpose of this chapter is to determine which of these two technologies would generate fewer ethical concerns. While there are moral similarities between the two technologies, the latter raises more concerns. In particular, it raises the possibility that individual moral decision-making and moral autonomy can be threatened by the use of automated implants.
