Abstract
Chronic subdural hematoma (cSDH) presents a multifaceted challenge in contemporary neurological practice, necessitating innovative therapeutic strategies. This comprehensive review explores the convergence of two promising interventions: statins and middle meningeal artery (MMA) Embolization. With cSDH incidence on the rise, particularly among the aging population and those with long-term anticoagulant usage, the traditional surgical avenues face limitations in recurrence rates and associated risk factors. Statins, heralded for their anti-inflammatory, vasculogenic, and angiogenic properties, are emerging as potential allies in cSDH management. Concurrently, MMA embolization offers a nuanced approach to target the neomembrane's blood supply, with evidence supporting its efficacy and safety. However, the synthesis of MMA embolization with statins remains relatively unexplored, presenting a complex interplay between inflammation modulation and blood supply interruption.

Abstract
BACKGROUND Cerebral aneurysms, especially large and giant aneurysms, pose challenges in neurointerventional surgery. Treatment choices involve clinical presentation, aneurysm details, and global resource variations. Neurointerventional methods, while innovative, may be cost restrictive in certain regions. In public healthcare, cost is crucial, notably in countries like Brazil. This study examines the device specific cost estimation of flow diverters (FD) and traditional stent assisted coiling (SAC) for large and giant cerebral aneurysms, providing insights into optimizing neurosurgical interventions within the Brazilian public health system's unique challenges. METHODS A comprehensive retrospective analysis was conducted at our medical center of cases of large and giant aneurysms treated between 2013 and 2023. Determination of the estimated number of coils for aneurysms previously treated with FDs at our center was made, with the cost of each case, and the difference between both treatments was calculated. RESULTS We investigated the profiles of 77 patients: 40 had large aneurysms (51.9%) and 37 had giant aneurysms (48.1%). Large aneurysms had a mean cost difference of US$274 (standard deviation (SD) $2071), underscoring the device specific cost estimation of FDs over SAC in their treatment. For giant aneurysms, the mean cost difference increased to $6396 (SD $2694), indicating FDs as the more economically sound choice. CONCLUSION Our study indicated that, for the treatment of giant aneurysms and some large aneurysms, the FD intervention was more economical than SAC.

Abstract
A growing proportion of percutaneous procedures are performed in outpatient centers. The shift from hospitals to ambulatory surgery centers and office-based laboratories has been driven by a number of factors, including declining reimbursements, increased patient demand, and competition for hospital resources. This transition has been dominated by the interventional radiology, cardiology, and vascular surgery fields. Cerebral angiography, in contrast, is still performed almost exclusively in a hospital-based setting, despite sharing many features with other endovascular procedures commonly performed in outpatient centers. As interest grows in performing cerebral angiography in outpatient endovascular centers, much can be learned from the decades of experience that our interventional colleagues have in the outpatient setting. In this article we examine the outpatient experience of other interventional fields and apply key principles to evaluate the prospect of outpatient neurointervention. The literature suggests that cerebral angiography can feasibly be performed in an outpatient center in both private and academic settings, as some groups have begun to do. Outpatient endovascular centers have helped to improve the patient experience, liberate inpatient resources, and control costs in other interventional fields, and might offer neurointerventionalists an opportunity to do the same.

Abstract
OBJECTIVES To verify the anatomical basis, ideal puncture sites, and potential pitfalls of the distal radial artery (dRA) in the anatomical snuffbox region for distal radial access (dTRA). MATERIALS AND METHODS Overall, 26 formalin-fixed upper limbs and computed tomography angiography (CTA) of the upper limbs of 168 consecutive patients were studied. Cadaveric dissection and dRA 3D reconstruction were used to evaluate the dRA route for dTRA. The puncture sites, dRA diameter, and angle of the dRA and tendons of the extensor pollicis brevis were also measured in the patients and cadavers. RESULTS The cadaver dissection provided more insights than did the dRA 3D reconstruction. However, preoperative evaluation had better diagnostic accuracy (p=0.024). Puncture sites 1 and 3 had a high success rate (63.2% possible success rate, 191/302). The DISFAVOR theory was put forward, in which 8 types of potential pitfalls that may interrupt puncture procedure or lead to a surgical failure were observed, including occlusion, stenosis, tortuosity, arteriovenous fistula, angioma, different radial artery (RA) ramifications, radial veins, and cephalic veins. The mean diameter of dRA based on cadaver dissection and CTA was 2.53 (SD=0.73) and 2.63 (SD=0.69) mm, respectively. Furthermore, the minimum distance from the outer layer of dRA to the skin was 5.71 (SD=2.0) mm based on CTA. The angle between the dRA and tendons of extensor pollicis brevis (TEPB) based on cadaver dissection and CTA was 58.0° (SD=21.5°) and 51.8° (SD=16.6°), respectively. CONCLUSIONS Puncture sites 1 and 3 were more suitable for the dTRA, and we put forward the DISFAVOR theory to summarize the 8 types of potential pitfalls during the use of dTRA.

Abstract
OBJECTIVE Evaluate the efficacy, safety, and patient satisfaction of transradial access (TRA) compared with conventional transfemoral access (TFA) for diagnostic cerebral angiography in elderly patients (≥65 years of age). METHODS We performed a retrospective review of patients receiving cerebral angiography via TRA or TFA between October 2020 and December 2021 at 3 institutions. Basic patient characteristics, angiographic data, postoperative complications, and patient satisfaction were collected for analysis. RESULTS Of the 357 enrolled elderly patients, 175 were performed through TRA and 182 were performed through TFA. There was no significant difference in mean fluoroscopy time (8.6 ± 3.8 minutes vs. 9.1 ± 3.1 minutes; P = 0.103) and radiation exposure (47.7 ± 10.8 Gy-cm2 vs. 49.8 ± 11.3 Gy-cm2; P = 0.068) between the TRA and TFA groups. However, the TRA group had a shorter procedural time (54.7 ± 6.2 minutes vs. 61.1 ± 5.6 minutes; P < 0.001) and less contrast agent (83.2 ± 28.1 mL vs. 100.1 ± 26.2 mL; P < 0.001) than the TFA group. In terms of safety, the incidence of minor vascular access complications in the TRA group was lower than that in the TFA group (1.7% vs. 8.8%; P = 0.003). The incidence of serious complications and neurologic complications in the TRA group was also lower, although the difference was not statistically significant. Overall patient satisfaction was higher in the TRA group than that in the TFA group. CONCLUSIONS TRA was an efficient and safe alternative to conventional TFA in elderly patients who underwent diagnostic cerebral angiography and who underwent TRA were more satisfied. Findings supported the radial-first strategy for cerebral angiography in elderly populations.

Abstract
BACKGROUND Outpatient diagnostic cerebral arteriograms are the most common procedure in neuroendovascular surgery, and the use of transradial access for these studies is growing. Although transradial access has been associated with lower hospital costs for elective diagnostic and interventional neuroendovascular procedures, no study has compared transfemoral access and transradial access costs for a homogenous population of patients undergoing outpatient diagnostic cerebral arteriogram. METHODS In this single-center retrospective study, the Value Driven Outcomes database was used to evaluate treatment costs for patients who underwent outpatient diagnostic cerebral arteriogram from January 2019 to December 2022. Propensity-score matching was performed to reduce confounders. Costs from each encounter were subcategorized into imaging, supplies, pharmacy, procedures, labs, and facility costs. RESULTS After matching, 337 patients each for transradial access and transfemoral access were available for analysis. A total of 118,992 cost data points were associated with all encounters. Overall, per-visit costs were 15.2% cheaper for patients who underwent transradial access versus transfemoral access (p < 0.001). Most of the cost difference was due to supplies (35.2% cost difference, p < 0.001) and procedure costs (9.3% cost difference, p < 0.001). No statistical differences were observed between the two approaches in imaging, pharmacy, labs, and facility costs (all p > 0.05). CONCLUSIONS Costs for outpatient diagnostic cerebral arteriogram were lower in patients who underwent transradial access versus transfemoral access because of supply and procedure costs. Understanding reasons for cost differences in common procedures is important for creating strategies to reduce overall healthcare costs. Additionally, addressing the cost differences of newer techniques may increase the likelihood that they are more readily implemented by hospitals and providers.

Abstract
BACKGROUND Transradial artery access (TRA) for neurointerventional procedures is gaining widespread acceptance. However, complications that were previously rare may arise as TRA procedures increase. Here we report a series of retained catheter cases with a literature review. METHODS All patients who underwent a neurointerventional procedure during a 23-month period at a single institution were retrospectively reviewed for a retained catheter in TRA cases. In cases of retained catheters, imaging was reviewed for anatomical variances in the radial artery, and clinical and demographic case details were analyzed. RESULTS A total of 1386 nondiagnostic neurointerventional procedures were performed during the study period, 631 (46%) initially via TRA. The 631 TRA cases were performed for aneurysm embolization (n=221, 35%), mechanical thrombectomy (n=116, 18%), carotid stent/angioplasty (n=40, 6%), arteriovenous malformation embolization (n=38, 6%), and other reasons (n=216, 34%). Thirty-nine (6%) TRA procedures crossed over to femoral access, most commonly because the artery of interest could not be catheterized (26/39, 67%). A retained catheter was identified in five cases (1%), and one (0.2%) patient had an entrapped catheter that was recovered. All six patients with a retained or entrapped catheter had aberrant radial anatomy. CONCLUSION Retained catheters for neurointerventional procedures performed via TRA are rare. However, this complication may be associated with variant radial anatomy. With the increased use of TRA for neurointerventional procedures, awareness of anatomical abnormalities that may lead to a retained catheter is necessary. We propose a simple protocol to avoid catheter entrapment, including in emergent situations such as TRA for stroke thrombectomy.

Abstract
INTRODUCTION Transfemoral access (TFA) is the primary access approach for neurointerventional procedures. Transradial access (TRA) is established in cardiology due to its lower complications, yet, it is at its early stages in neuroprocedures. This study performs an early exploration of the economic impact associated with the introduction of TRA in diagnostic and therapeutic neuroprocedures from the Spanish NHS perspective. METHODS An economic model was developed to estimate the cost and clinical implications of using TRA compared to TFA. Costs considered access-related, complications and recovery time costs obtained from local databases and experts' inputs. Clinical inputs were sourced from the literature. A panel of eight experts from different Spanish hospitals, validated or adjusted the values based on local experience. Hypothetical cohorts of 10,000 and 1000 patients were considered for diagnostic and therapeutic neuroprocedures respectively. Deterministic sensitivity analysis was performed. RESULTS TRA in diagnostic procedures was associated with lower costs with savings ranging between €486 and €157 depending on the TFA recovery time considered. TRA is estimated to lead to 158 fewer access-site complications. In therapeutic procedures, TRA resulted in 76.4 fewer complications and was estimated to be cost-neutral with an incremental cost of €21.56 per patient despite recovery times were not included for this group. Variation of the parameters in the sensitivity analysis did not change the direction of the results. LIMITATIONS Clinical data was obtained from literature validated by experts therefore results generalizability is limited. In therapeutic neuroprocedures, there is an experience imbalance between approaches and recovery times were not included hence the total impact is not fully captured. CONCLUSIONS The early economic model suggests that implementing TRA is associated with reduced costs and complications in diagnostic procedures. In therapeutic procedures, TRA lead to fewer complications and it is estimated to be cost-neutral, however its full potential still needs to be quantified.

Abstract
BACKGROUND Modern medicine necessitates the delivery of increasingly complex health care while minimizing cost. Transradial access (TRA) for neuroendovascular procedures is becoming more common as accumulating data demonstrate fewer complications, improved patient satisfaction, and high rates of treatment success compared with the transfemoral access (TFA) approach; however, disparities in cost between these approaches remain unclear. We compared supply and equipment costs between TRA and TFA for diagnostic cerebral angiography and evaluate the specific items that account for these differences. METHODS We reviewed all adult patients who underwent diagnostic cerebral angiography from July 1, 2019 to December 31, 2019. Data related to patient demographics, vascular access site, catheters used, cost of catheters, arterial access sheath use, cost of sheaths, closure devices used, and cost of closure devices were collected. RESULTS The transradial approach resulted in higher price of radial access sheath; however, the overall cost of closure devices was much lower in TRA group than in the TFA cohort. There was no significant difference in the cost of catheters. Overall, the total supply costs for TRA cerebral angiography were significantly lower than those of TFA cerebral angiography. The relative materials cost difference of using TRA was 20.9%. CONCLUSION This study is the first itemized materials cost analysis of TRA versus TFA cerebral angiography. TRA necessitates the use of a more expensive access sheath device; however, this cost is offset by the increased cost of devices used for femoral arteriotomy closure. Overall, the supply and equipment costs were significantly lower for TRA than TFA.

Emergency Department Visits for Chronic Subdural Hematomas within 30 Days after Surgical Evacuation with and without Middle Meningeal Artery Embolization. AJNR Am J Neuroradiol 2022; 43:1148-1151. [PMID: 35863784 PMCID: PMC9575430 DOI: 10.3174/ajnr.a7572] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/16/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE Middle meningeal artery embolization after surgical evacuation of a chronic subdural hematomas is associated with fewer treatment failures than surgical evacuation. We compared emergency department visits within 30 days for patients with chronic subdural hematomas with and without adjunctive middle meningeal artery embolization. MATERIALS AND METHODS All cases of chronic subdural hematoma treated from January 1, 2018, through December 31, 2020, were retrospectively reviewed. Treatment was classified as surgery only or surgery combined with middle meningeal artery embolization. The primary outcome was 30-day emergency department presentation and readmission. RESULTS Of 137 patients who met the study criteria, 28 (20%) underwent surgery combined with middle meningeal artery embolization. Of these 28 patients, 15 (54%) underwent planned middle meningeal artery embolization and 13 (46%) underwent embolization after surgical failure. The mean chronic subdural hematoma size at presentation in the group with surgery only (n = 109, 20.5 [SD, 6.9] mm) was comparable with that in the combined group (n = 28, 18.7 [SD, 4.5] mm; P = .16). A significantly higher percentage of the surgery-only group presented to the emergency department within 30 days compared with the combined group (32 of 109 [29%] versus 2 of 28 [7%] patients; P = .02). No significant difference was found with respect to readmission (16 [15%] versus 1 [4%] patient; P = .11). Nine patients (8%) in the surgery-only group were readmitted for significant reaccumulation or residual subdural hematoma compared with only 1 patient (4%) in the combined group (P = .40). CONCLUSIONS Surgical evacuation combined with middle meningeal artery embolization in patients with chronic subdural hematoma is associated with fewer 30-day emergency department visits compared with surgery alone.

Abstract
BACKGROUND Few reports discuss variables associated with improved outcomes after middle meningeal artery (MMA) embolization for chronic subdural hematomas (cSDHs). We analyzed radiographic evidence of cSDH clearance after MMA embolization to elucidate optimal techniques, hematoma clearance rates, and suitable length of follow-up. METHODS Patients who underwent MMA embolization for cSDH from January 1, 2018 through December 31, 2020 were analyzed. Patient characteristics, demographics, and technical procedural details were examined. Outcomes for cSDHs analyzed included complete or near-complete resolution at 30, 90, and 180 days following embolization. A multivariable logistic regression analysis identified variables predictive of rapid clearance and resolution of hematomas at 90 days. RESULTS The study cohort comprised 66 patients with 84 treated cSDHs. The mean (SD) cSDH size differed significantly at 30-day (8.8 (4.3) mm), 90-day (3.4 (3.0) mm), and 180-day (1.0 (1.7) mm) follow-up (p<0.001). More cSDHs had complete or near-complete resolution at 180 days (92%, 67/73) than at 90 (63%, 45/72) and 30 days (18%, 15/84) post-embolization (p<0.001). Only distal embolysate penetration was independently associated with rapid clearance (OR 3.9, 95% CI 1.4 to 11.1; p=0.01) and resolution of cSDHs at 90 days (OR 5.0, 95% CI 1.7 to 14.6; p=0.003). CONCLUSION Although 63% of cSDHs with MMA embolization had complete or near-complete resolution by 90 days post-procedure, 92% reached this stage by 180 days. Therefore, 90-day follow-up may be insufficient to determine the effectiveness of MMA embolization for cSDHs, particularly compared with surgical evacuation alone. Also, distal MMA penetration may be associated with more rapid hematoma clearance.

The Rist radial access system: a multicenter study of 152 patients. J Neurointerv Surg 2021; 14:403-407.

Abstract
BACKGROUND Transradial access (TRA) for neurointervention is becoming increasingly popular as experience with the technique grows. Despite reasonable efficacy using femoral catheters off-label, conversion to femoral access occurs in approximately 8.6-10.3% of TRA cases, due to an inability of the catheter to track into the vessel of interest, lack of support, or radial artery spasm. METHODS This is a multicenter, retrospective case series of patients undergoing neurointerventions using the Rist Radial Access System. We also present our institutional protocol for using the system. RESULTS 152 patients were included in the cohort. The most common procedure was flow diversion (28.3%). The smallest radial diameter utilized was 1.9 mm, and 44.1% were performed without an intermediate catheter. A majority of cases (96.1%) were completed successfully; 3 (1.9%) required conversion to a different radial catheter, 2 (1.3%) required conversion to femoral access, and 1 (0.7%) was aborted. There was 1 (0.7%) minor access site complication and 4 (2.6%) neurological complications. CONCLUSIONS The Rist catheter is a safe and effective tool for a wide range of complex neurointerventions, with lower conversion rates than classically reported.

Abstract
BACKGROUND AND PURPOSE The feasibility and safety of transradial angiography is not established outside the adult literature. The objective of this study was to assess the feasibility and safety of transradial access for neuroangiography in adolescents. MATERIALS AND METHODS A retrospective case-control study was performed, comparing transradial neuroendovascular procedures in adolescents (age range, 10-18 years) with an age- and procedure-matched cohort of transfemoral neuroendovascular procedures. Clinical and procedural details, including type of procedure, conversion rate, fluoroscopy time, radiation dose, complications, and readmissions, were reported by descriptive statistics or measures of central tendency and compared using a t test or nonparametric equivalent. A P value < .05 was considered statistically significant. RESULTS Twenty adolescents (mean age, 14.6 [SD, 1.7] years, M/F ratio = 9:11) who underwent transradial neuroangiography were compared against 20 adolescents (mean age, 14.4 [SD, 2.1 ] years, M/F ratio = 12:8) who underwent transfemoral neuroangiography. We found no significant difference in procedural success (0% conversion rate), fluoroscopy times (33.7 [SD, 40.2] minutes versus 23.3 [SD, 26.2] minutes, P = .34) and radiation dose (150.9 [SD, 133.7] Gy×cm2 and 122.9 [SD, 79.7] Gy×cm,2 P = .43) There were 2 self-limiting postprocedural complications in the transradial group. There were no major hemorrhages, need for further interventions, or readmissions in either group. CONCLUSIONS The benefits of transradial angiography described for adults can likely be safely extended to adolescents. These are important data before transitioning to smaller children and should be prospectively evaluated in a larger cohort.
