Clin Neurol Neurosurg 2024; 245:108471. [PMID: 39106636 DOI: 10.1016/j.clineuro.2024.108471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 06/27/2024] [Accepted: 07/26/2024] [Indexed: 08/09/2024]
Abstract
OBJECTIVE Although mechanical thrombectomy (MT) is primarily performed via transfemoral access (TFA), transradial access (TRA) is a potential alternative in older patients or those with tortuous vessels. However, the small radial artery diameter restricts the use of large-bore balloon guides and aspiration catheters, a limitation that may be overcome using the sheathless technique. Thus, we aimed to explore the feasibility, efficacy, and safety of sheathless TRA-MT as a first-line treatment approach for acute ischemic stroke. METHODS This single-center retrospective case series included patients who underwent TRA-MT as first-line treatment between September 2020 and June 2023. Per our MT protocol, TRA was not the first-line approach in cases of left anterior circulation lesions with a type 3 aortic arch. We evaluated treatment effectiveness based on the successful recanalization rate, puncture-to-recanalization time, and modified first-pass effect; access route effectiveness based on the puncture-to-first-pass time and switch-to-TFA rate; and procedure safety based on procedure-related and severe puncture site complications. RESULTS Sheathless 8-F guide catheters were used in 68 % and large-bore aspiration catheters in 70 % of the procedures. Successful recanalization was achieved in 98 % of the patients, with a modified first-pass effect in 54 % of them. The median puncture-to-first-pass and puncture-to-recanalization times were 20.5 and 33 min, respectively. The rate of procedure-related complications was low (4 %), with no severe puncture site complications. CONCLUSION Sheathless TRA-MT enabled the use of large-bore guide and aspiration catheters, providing a swift approach to the target and satisfactory outcomes, and might be an effective first-line treatment for acute ischemic stroke.

Marlowe FJA, Powell E. Evaluating the safety and efficacy of transradial approach for thrombectomy in posterior circulation stroke. A systematic literature review and meta-analysis. Interv Neuroradiol 2024; 30:317-325. [PMID: 35673707 PMCID: PMC11310717 DOI: 10.1177/15910199221107259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 05/27/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Transradial access (TRA) is becoming more popular in neurointerventional radiology procedures and has been associated with reduced mortality, morbidity and access site complications. Guidelines state that TRA is a feasible option for posterior circulation thrombectomy however the evidence base is limited and no systematic literature review has yet been undertaken to evaluate its safety and efficacy. METHODS The Cochrane Library, PubMed, Web of Science, Scopus, TRIP and Embase databases were searched. Outcomes collected included TICI scores, puncture to recanalisation time, mRS scores at 90 days and access site complications. RESULTS 291 records were identified and 31 full text articles were assessed for eligibility. Eight studies met the inclusion criteria and were meta-analysed. The rate of TICI 2b-3 was 94.7% (89.7-99.8% at 95% CI), TICI 3 was 67.9% (42.2-93.6% at 95% CI) and mRS 0-2 at 90 days was 49.8% (31.5-68.1% at 95% CI). Median puncture to reperfusion times were extracted from three studies as 24 (IQR 18-40), 24 (IQR 17.5-56.5) and 27 (IQR 24-33.5) minutes. No access site complications were reported. TICI 2b-3, TICI 3 and mRS scores were comparable to data for transfemoral access (TFA) from a large systematic review. Puncture to recanalisation times appeared lower than the TFA data but statistical comparison of this outcome was not possible. CONCLUSIONS The use of TRA in posterior circulation thrombectomy is safe and effective with comparable results to TFA. Further research with a larger sample size is required to fully investigate the potential for shortened puncture to recanalisation times.

Abstract
BACKGROUND Transfemoral access is predominantly used for mechanical thrombectomy in patients with stroke with a large vessel occlusion. Following the interventional cardiology guidelines, routine transradial access has been proposed as an alternative, although its safety and efficacy remain controversial. We aim to explore the noninferiority of radial access in terms of final recanalization. METHODS The study was an investigator-initiated, single-center, evaluator-blinded, noninferiority randomized clinical trial. Patients with stroke undergoing mechanical thrombectomy, with a patent femoral artery and a radial artery diameter ≥2.5 mm, were randomly assigned (1:1) to either transradial (60 patients) or transfemoral access (60 patients). The primary binary outcome was the successful recanalization (expanded Treatment in Cerebral Ischemia score, 2b-3) assigned by blinded evaluators. We established a noninferiority margin of -13.2%, considering an acceptable reduction of 15% in the expected recanalization rates. RESULTS From September 2021 to July 2023, 120 patients were randomly assigned and 116 (58 transradial access and 58 transfemoral access) with confirmed intracranial occlusion on the initial angiogram were included in the intention-to-treat analysis. Successful recanalization was achieved in 51 (87.9%) patients assigned to transfemoral access and in 56/58 (96.6%) patients assigned to transradial (adjusted 1 side risk difference [RD], -5.0% [95% CI, -6.61% to +13.1%]) showing noninferiority of transradial access. Median time from angiosuite arrival to first pass (femoral, 30 [interquartile range, 25-37] minutes versus radial: 41 [interquartile range, 33-62] minutes; P<0.001) and from angiosuite arrival to recanalization (femoral: 42 (IQR, 28-74) versus radial: 59.5 (IQR, 44-81) minutes; P<0.050) were longer in the transradial access group. Both groups presented 1 severe access complication and there was no difference in the rate of access conversion: transradial 7 (12.1%) versus transfemoral 5 (8.6%) (P=0.751). CONCLUSIONS Among patients who underwent mechanical thrombectomy, transradial access was noninferior to transfemoral access in terms of final recanalization. Procedural delays may favor transfemoral access as the default first-line approach. REGISTRATION URL: https://www.clinicaltrials.gov; Unique identifier: NCT05225636.

Neurointervention 2024; 19:6-13. [PMID: 38224721 PMCID: PMC10910181 DOI: 10.5469/neuroint.2023.00500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 12/29/2023] [Accepted: 01/05/2024] [Indexed: 01/17/2024] Open
Abstract
PURPOSE Mechanical thrombectomy (MT) is the standard of care for acute ischemic stroke (AIS) due to large vessel occlusion (LVO). The choice of a transradial approach (TRA) for anterior circulation LVOs is still debatable; the use of a specific tricoaxial system could help mitigate numerous issues related to transradial MT. MATERIALS AND METHODS From November 2022 to November 2023, 22 patients underwent TRA-MT for anterior circulation LVOs, both as first-line and rescue from transfemoral approach (TFA) failure, with the same triaxial setup consisting of a 7F introducer sheath, 7F guide catheter, and aspiration catheters ranging from 5.5F to 5F in relation to the occlusion site. Choice of thrombectomy technique was at operator discretion. Patients' demographic data, clinical presentation, treatment details, complications, rate of crossover to TFA, successful revascularization (modified thrombolysis in cerebral infarction [mTICI] score ≥2b), and good clinical outcome at 3 months (modified Rankin scale [mRS] 0-2) were reported. RESULTS Of 20 patients selected, 10 (50%) had occlusion of M1 segment of middle cerebral artery (MCA), 6 (30%) of internal carotid artery (ICA) terminus, and 4 (20%) with M2 MCA occlusions; 12/20 (60%) were right-sided occlusions and 8/20 (40%) were left-sided. The mean National Institutes of Health Stroke Scale score was 9.25 at admission. Successful revascularization to mTICI 2b-3 was achieved in 18/20 patients (90%). Intracranial complications were reported in 2 (10%) patients. Rate of radial artery occlusion at 24 hours was 10,6%; no access-site haemorrhagic complications were reported. Symptomatic intracranial hemorrhage occurred in 2 (10%) patients. mRS score 0-2 at 3 months was 50%. CONCLUSION The high technical effectiveness and good safety profile of this specific tricoaxial setup for TRA-MT in AIS, even for large proximal LVOs, could constitute a viable alternative to TFA-MT in selected cases.

Abstract
BACKGROUND The transradial approach (TRA) for neurointerventional procedures is increasingly being used given its technical feasibility and safety. However, catheter trackability and device deliverability are reported barriers to TRA adoption. METHODS This is the first report describing the technical feasibility and performance of using the Zoom RDL Radial Access System (Imperative Care, Inc., Campbell, CA) in 29 patients who underwent neurointerventional procedures from October 2022 to January 2023 in a single-center institution. RESULTS Mean age of the study population was 61.9±17.2 years, 79.3% were male (23/29), and 62.1% were black (18/29). The most common procedures were stroke thrombectomy (31.0%, 9/29) and aneurysm embolization (27.6%, 8/29). All the stroke thrombectomy procedures were successfully performed; first-pass effect rate (mTICI≥2 c in one pass) was achieved in 66.7% (6/9) of cases. We used TRA in 86.2% of cases (25/29), including distal radial/snuffbox access in 31.0% (9/29) of cases. The radial diameter was >2 mm for all cases. An intermediate/aspiration catheter was used in 89.7% (26/29) of cases. Access success was achieved in 89.7% of cases (26/29); two cases required conversion from TRA to transfemoral approach (6.9%) and one case required conversion to a different guide catheter (3.4%). There were no access site complications or other Zoom RDL-related complications. One intracerebral hemorrhage, and one procedure-related thrombus were observed. CONCLUSIONS The use of Zoom RDL Radial Access System is technically feasible and effective for complex neurointerventional procedures with low complication rates.

Mechanical thrombectomy with a balloon-guide catheter: sheathless transradial versus transfemoral approach. J Neurointerv Surg 2024; 16:187-191. [PMID: 36581453 DOI: 10.1136/jnis-2022-019607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Accepted: 12/08/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND The transradial approach (TRA) for mechanical thrombectomy (MT) for acute ischemic stroke has been limited by the size of catheters usable in the radial artery, with the smaller access site precluding balloon-guide catheter (BGC) use. However, promising results have been reported for a TRA with a sheathless BGC (sTRA). We sought to perform a comparative study of MT with a BGC via the sTRA versus the transfemoral approach (TFA). METHODS A retrospective review of our MT database was conducted. Baseline, procedure-related, and outcome data were compared for patients aged ≥18 years with anterior circulation large vessel occlusion, Alberta Stroke Program Early CT Score ≥6, and prestroke modified Rankin Scale score ≤2 treated with either approach. RESULTS Ninety-three consecutive patients (34 sTRA and 59 TFA) were included. Both groups had similar demographics, comorbidities, stroke severity, intravenous alteplase use, and occlusion location. Mean time from puncture to final recanalization was faster in the sTRA group (29 vs 36 min, p=0.059) despite a higher access site crossover rate in the sTRA group (11.8% vs 0%, p=0.016). There were no differences between groups regarding last modified Thombolysis in Cerebral Infarction score; first-pass or modified first-pass effect; time from last known well to puncture; use of stent-retriever, aspiration, or combination first approach; number of passes; symptomatic intracranial hemorrhage; hospital stay; 90-day functional independence; and mortality. National Institutes of Health Scale score and modified first-pass effect were the only independent predictors of poor outcomes. CONCLUSIONS Comparable patients treated with MT via the sTRA or TFA had similar angiographic and clinical outcomes.

World Neurosurg 2023; 179:e281-e287. [PMID: 37625636 DOI: 10.1016/j.wneu.2023.08.077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023]
Abstract
BACKGROUND Challenging arterial anatomy may prevent timely endovascular treatment (EVT) of acute ischemic stroke (AIS) through a transfemoral approach prompting the use of alternative access routes. We determined the crossover rate from femoral to radial access during EVT of AIS due to large vessel occlusion and identified its radiological predictors and clinical outcomes. MATERIALS AND METHODS Retrospective review of all AIS patients who underwent EVT at a single institution from January 2016 to March 2021 was performed. A primary and a secondary radial group depending on whether the radial approach was used primarily or secondary to failure of transfemoral approach were compared. RESULTS A total of 358 consecutive AIS patients with large vessel occlusion underwent EVT. Radial approach was used primarily in 6 patients (primary radial [PR]) and secondarily in 16 patients (secondary radial [SR]). The rate of femoral to radial crossover was 4.7%. Type III arch and bovine arch configurations were the most common characteristic in the crossover group. Radial access was successful to secure intracranial access in all cases of PR and in 87% of crossover cases. There was no significant difference between the rates of successful reperfusion (53.3% SR, 83% PR, P = 0.20), National Institutes of Health Stroke Scale score on discharge (19 SR, 18 PR group, P = 0.90), or good outcome defined as modified Rankin Scale score 0-2 (13.3% SR, 33.3% PR, P = 0.29). CONCLUSIONS A radial approach can be considered during EVT of AIS due to large vessel occlusion either primarily or secondarily with a lower threshold to switch from the femoral approach in cases of challenging anatomy.

Transradial versus transfemoral access for mechanical thrombectomy in acute ischemic stroke: A retrospective cohort study. J Stroke Cerebrovasc Dis 2023; 32:107282. [PMID: 37659190 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Revised: 07/21/2023] [Accepted: 07/25/2023] [Indexed: 09/04/2023] Open
Abstract
BACKGROUND The objective of this study was to compare procedural and clinical outcomes in patients with acute ischemic stroke (AIS) treated via transradial access (TRA) mechanical thrombectomy (MT) versus conventional transfemoral access (TFA). METHODS We performed a retrospective analysis of consecutive patients with AIS treated with TRA versus TFA MT at our tertiary comprehensive stroke center. Access choice was individualized based on occlusion site, aortic and arch anatomy. Outcomes were extracted from our institutional stroke registry and included procedural time, Thrombolysis in Cerebral Infarction (TICI) reperfusion score, NIHSS, 90-day mRS and 90-day mortality. Comparisons were performed using Student t-Test and Fischer's exact test as appropriate. RESULTS 175 mechanical thrombectomies were performed during the study interval; 39 (22%) were performed via TRA and 136 (79%) TFA. Access to reperfusion time was 36.3 ± 24.5 minutes in the TRA group and 21.9 ± 17.6 in the TFA group (p<0.001). The proportion of patients with a TICI reperfusion score of 2b or 3 was similar in both groups (TRA: 34 (87%) vs. TFA: 121 (89%) p=0.559. The median 90-day mRS was similar between both groups (p=0.170), as was the 90-day mortality (p = 0.509). CONCLUSIONS While TFA is faster in our cohort, TFA and TRA are both safe and effective for MT in acute ischemic stroke. While TFA remains mainstay, TRA can be valuable in variant anatomy despite its technical limitations. Individualizing access based on advanced imaging and patient factors may improve practice; however, updates in catheter and access technology are necessary to optimize outcomes with TRA.

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
PURPOSE The transradial approach (TRA) in neuroendovascular treatment is known to have a lower risk of complications than the transfemoral approach (TFA). However, little research has focused on assessments of efficacy and risk of complications in the treatment of intracranial aneurysms. This study aimed to compare the efficacy and complications of TRA and TFA in coil embolization of unruptured intracranial aneurysms (UIAs) at our institution. METHODS Consecutive patients who underwent endovascular surgery via TRA or TFA at a single institution from 1 April 2019, to 28 February 2022, were retrospectively analyzed. Patients were classified into TRA and TFA groups and assessed using propensity-adjusted analysis for outcomes including fluoroscopy time, volume embolization ratio (VER), and complications. RESULTS A total of 163 consecutive UIAs were treated with coil embolization during the 35-months study period. The incidence of minor access site complications (ASCs) was significantly higher with TFA (20%, 25/126) than with TRA (2.7%, 1/37; p = 0.01). Propensity-adjusted analysis (matched for age, sex, aneurysm volume, embolization technique, and sheath size) revealed that TRA was associated with a lower risk of minor ASCs (odds ratio, 0.085; 95% confidence interval 0.0094-0.78; p = 0.029). However, TRA did not differ significantly from TFA with respect to fluoroscopy time, VER, major ASCs, and non-ASCs. CONCLUSIONS Coil embolization for UIAs via TRA can reduce risk of minor ASCs without increasing the risk of non-ASCs compared with conventional TFA, and can achieve comparable results in term of efficacy and fluoroscopy time.

Abstract
BACKGROUND AND PURPOSE IV thrombolysis with alteplase before mechanical thrombectomy for emergent large-vessel-occlusion stroke is associated with access-site bleeding complications. However, the incidence of femoral access-site complications with tenecteplase before mechanical thrombectomy requires exploration. Here, femoral access-site complications with tenecteplase versus alteplase before mechanical thrombectomy for large-vessel-occlusion stroke were compared. MATERIALS AND METHODS All patients receiving IV thrombolytics before mechanical thrombectomy for large-vessel-occlusion stroke who presented from January 2020 to August 2022 were reviewed. In May 2021, our health care system switched from alteplase to tenecteplase as the primary thrombolytic for all patients with stroke, facilitating the comparison of alteplase-versus-tenecteplase femoral access-site complication rates. Major (requiring surgery) and minor (managed conservatively) access-site complications were assessed. RESULTS One hundred thirty-nine patients underwent transfemoral mechanical thrombectomy for large-vessel-occlusion stroke, of whom 46/139 (33.1%) received tenecteplase and 93/139 (66.9%) received alteplase. In all cases (n = 139), an 8F sheath was inserted without sonographic guidance, and vascular closure was obtained with an Angio-Seal. Baseline demographics, concomitant antithrombotic medications, and periprocedural coagulation lab findings were similar between groups. The incidence of conservatively managed groin hematomas (2.2% versus 4.3%), delayed access-site oozing requiring manual compression (6.5% versus 2.2%), and arterial occlusion requiring surgery (2.2% versus 1.1%) was similar between the tenecteplase and alteplase groups, respectively (P = not significant). No dissection, arteriovenous fistula, or retroperitoneal hematoma was observed. CONCLUSIONS Tenecteplase compared with alteplase before mechanical thrombectomy for large-vessel-occlusion stroke is not associated with an alteration in femoral access-site complication rates.

Abstract
BACKGROUND The transradial approach (TRA) for endovascular procedures has become a frequent practice in neurointervention. Advantages of the TRA include less access-site complications, early ambulation, and less postprocedural pain. The Rist 079 radial access guide catheter (Medtronic) is the first device designed specifically for neurointerventions performed through the TRA. In this study, we report our initial experience with the Rist catheter in a variety of neurointerventional procedures, aiming to evaluate the performance of this device and discuss its limitations. METHODS A prospectively maintained database was retrospectively searched to identify patients who underwent procedures using the Rist catheter. Information on demographics, procedural details, and complications was recorded. RESULTS Seventy-eight patients were included in the study, with a mean age of 60.3 years (range, 25-92 years); 45 (57.7%) were men. The interventional or diagnostic procedure was successfully completed in 77 patients (98.7%). The radial artery was the primary access-site choice in 71 patients (91%). The most frequent type of procedures performed were coiling or stent-assisted coiling (16.7%) and angioplasty and stenting (16.7%), followed by middle meningeal artery embolization (14.1%). Crossover to femoral artery access while maintaining use of the Rist was done in 5 cases (6.4%). Reasons for access or procedural failure included anatomical anomaly of the target vessel, unfavorable geometry of the great vessels, and proximal tortuosity of the supra-aortic vessels. CONCLUSION We demonstrated a high success rate with use of the Rist catheter system for a variety of procedures.

Abstract
INTRODUCTION The use of short-term mechanical circulatory support (MCS) devices and procedures for function- and life-sustaining therapy is becoming a routine practice at many centers. Concomitant with the increasing use of MCS is the increasing recognition of acute brain injuries, including acute ischemic stroke, which may be caused by a myriad of MCS-driven factors. The aim of this case series was to document our experience with mechanical thrombectomy (MT) for ischemic stroke in extracorporeal membrane oxygenation (ECMO) patients. METHODS We retrospectively reviewed a prospectively maintained database of patients undergoing endovascular thrombectomy for large vessel occlusion at our institution. We identified patients that were on ECMO and underwent thrombectomy. Baseline demographics and procedural and functional outcomes were collected. RESULTS Three patients on ECMO were identified to have a large vessel occlusion and underwent thrombectomy. Two patients had an internal carotid artery terminus occlusion and one had a basilar artery occlusion. An mTICI 3 recanalization was achieved in all patients without postoperative hemorrhagic complications. Two patients achieved a 3-month mRS of 1, while one had mRS 4. CONCLUSION Ischemic stroke can be associated with significant morbidity in MCS patients. We demonstrate that MT can be safely performed in this patient population with good outcomes.

Abstract
Objective Marfan's syndrome (MFS) is a systemic connective tissue disorder with autosomal dominant inheritance. Cardiovascular complications of MFS such as aortic root or valve disease and aortic aneurysm or dissection are potential cause of access route problems of mechanical thrombectomy (MT) for acute ischemic stroke (AIS). Here, we report a case of a patient with MFS who underwent MT for AIS. Case Presentation A 58-year-old woman with MFS presented with a sudden onset of consciousness disturbance and right hemiparesis, and was referred to our hospital. After the infusion of tissue plasminogen activator, CTA showed a type III arch in the aortic arch and severe tortuosity of the thoracoabdominal aorta; thus, angiography was performed using the transbrachial approach. Left common carotid angiogram showed complete recanalization of the left middle cerebral artery. On the sixth day, the patient presented a sudden consciousness disturbance and left hemiparesis. MRA showed right internal carotid artery occlusion. MT was performed by the transbrachial approach, and complete recanalization was achieved on the first pass. Conclusion MT via the transbrachial approach is a treatment option that should be considered, especially in MFS, where the transfemoral approach is difficult due to anatomical problems.

Abstract
INTRODUCTION Vertebral artery (VA) ostial stenosis is notoriously difficult to treat using bare-metal stents owing to high rates of restenosis and stent kinking and breakage. We investigated the safety and effectiveness of treatment with a drug-eluting, balloon-expandable coronary stent (Resolute Onyx, Medtronic). METHODS Our prospectively maintained database was retrospectively searched for consecutive patients diagnosed with VA ostial stenosis who underwent Resolute Onyx stenting with/without angioplasty between January 1, 2015 and January 1, 2022. Patient demographics and clinical and radiographic presentations were recorded. Occlusion location, stenosis severity, contralateral disease, devices used, and intraprocedural and postprocedural complications were noted. Outcomes were assessed based on new or recurrent stroke, transient ischemic attack (TIA), or intracranial hemorrhage (ICH). Patients were followed up clinically and with radiographic imaging for in-stent stenosis. RESULTS Twenty-six patients were included in our study (21 men [80.8%]; mean age 70.3 ± 9.8 years). Symptomatic patients presented with TIA (11/26, 42.3%) and stroke (10/26; 38.5%). Mean stenosis in the study cohort was 74.9 ± 13.0%. One (3.8%) intraprocedural complication was encountered whereby the stent failed to open despite several attempts and was exchanged with a new one without issues. No in-hospital postprocedure stroke, TIA, or mortality was reported. During a mean 16.2 ± 13.6 months' follow up, two patients developed symptomatic in-stent restenosis that was treated with balloon angioplasty. CONCLUSIONS We report the first case series of Resolute Onyx drug-eluting stenting including 30-day postprocedure stroke/TIA rates and clinical/radiographic follow up and demonstrate safe and effective treatment of symptomatic and asymptomatic VA ostial stenosis.

Abstract
BackgroundTrans-radial access (TRA) for MMA embolization has grown due to lower access site complications and greater patient satisfaction. Here, we describe the feasibility of utilizing a 6F Envoy Simmons 2 (6F-SIM2) as a guide catheter with TRA and compare outcomes with trans-femoral approach (TFA) in a single center case series.MethodsWe performed a retrospective review of patients who underwent MMA embolization for management of chronic subdural hematoma (cSDH). TRA was performed by utilizing a combination of 6F 90cm Envoy (Codman & Shurtleff, Inc., Rayham, MA) Simmons 2 guide catheter and 5F 125cm Sofia (Microvention, Aliso Viejo, CA) intermediate catheter. Outcomes measured are Modified Rankin Score (mRS) at 90 days, inpatient mortality, post-embolization recurrence, fluoroscopy time and radiation exposure.ResultsA total of 71 patients underwent 97 MMA embolization overall with 65 (67%) in trans-femoral access group, 11 (11.3%) in trans-radial access without use of Simmons 2 Guide catheter group and 21 (21.6%) in trans-radial access with use of Simmons 2 Guide catheter group. There were no direct access-related complications in either group. One patient had thromboembolic stroke in trans-femoral group. There was no difference in average procedure-related total fluro time or radiation dose among all three groups.ConclusionTrans-radial approach using 6F-SIM2 guide catheter coupled with 5F Sofia intermediate catheter is safe and effective. It provides an alternative approach to access distal branches of bilateral anterior circulation in elderly patients with difficult anatomy undergoing MMA embolization.

Abstract
Endovascular treatment is widely used in the treatment of intracranial aneurysms. However, neurosurgeons are sceptical about endovascular access via the radial artery. We performed a systematic review and meta-analysis to compare the effectiveness and safety of transradial and transfemoral artery access in patients with intracranial aneurysms. We systematically searched the PubMed, Embase, and Cochrane databases for studies comparing the two approaches. The primary outcome was total complications, and the secondary outcomes were access site complications, intracranial haemorrhage, stroke, thromboembolism, silent infarct, re-treatment rate, mortality, complete occlusion of intracranial aneurysms, procedure duration, and length of hospital stay. A random-effects model was used to assess the pooled data. Of the 100 identified studies, 6 were eligible (a total of 3764 participants). There were no significant differences in total complications(odds ratio [OR] = 0.69, 95% confidence interval [CI] [0.33, 1.45], p = 0.32), complete occlusion of intracranial aneurysms (OR = 1.02, 95%CI [0.77,1.37], p = 0.87), procedure duration (mean difference [MD] = - 6.24, 95%CI [- 14.75, - 1.54], p = 0.95), or length of hospital stay (MD = 2.204, 95%CI [- 0.05, 4.45], p = 0.95), access site complications (OR = 0.49, 95%CI [0.16, 1.52], p = 0.22), intracranial haemorrhage (OR = 1.07, 95%CI [0.49, 2.34], p = 0.86), stroke (OR = 0.59, 95%CI [0.20, 1.77], p = 0.35), thromboembolism (OR = 0.85, 95%CI [0.33, 2.17], p = 0.74), silent infarct (OR = 0.69, 95%CI [0.04, 11.80], p = 0.80), retreatment rate (OR = 1.32, 95%CI [0.70, 2.48], p = 0.39), mortality (OR = 1.41, 95%CI [0.06, 5.20], p = 0.61), immediate occlusion (OR = 0.99, 95%CI [0.64, 1.51], p = 0.95), and occlusion during follow-up (OR = 1.10, 95%CI [0.56, 2.16], p = 0.74) between the transradial and transfemoral groups. This study showed comparable safety and efficacy outcomes between transradial and transfemoral access in patients with intracranial aneurysms treated endovascularly. Future large randomised trials are warranted to confirm these findings.

Safety of Sheathless Transradial Balloon Guide Catheter Placement for Acute Stroke Thrombectomy. World Neurosurg 2022; 165:e235-e241. [PMID: 35691519 DOI: 10.1016/j.wneu.2022.06.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 06/02/2022] [Accepted: 06/02/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Transradial access has been described for mechanical thrombectomy in acute stroke, and proximal balloon occlusion has been shown to improve recanalization and outcomes. However, sheathed access requires a larger total catheter diameter at the access site. We aimed to characterize the safety of sheathless transradial balloon guide catheter use in acute stroke intervention. METHODS Consecutive patients who underwent sheathless right-sided transradial access for thrombectomy with a balloon guide catheter were identified in a prospectively collected dataset from 2019 to 2021. Demographics, procedure details, and short-term outcomes were collected and reported with descriptive statistics. RESULTS A total of 48 patients (20 women) with a mean age of 72.3 years were identified. Of patients, 56.3% had occlusions in the left-sided circulation; 35 (72.9%) had M1 occlusions, 7 (14.6%) had M2 occlusions, and 6 (12.5%) had internal carotid artery occlusions. Tissue plasminogen activator was administered to 16 (33.3%) patients. Five (10.4%) patients underwent intraprocedural carotid stenting. The cohort had successful reperfusion after a median of 1 (interquartile range: 1, 2) pass. Median time from access to recanalization was 31 (interquartile range: 25, 53) minutes. A postprocedural Thrombolysis In Cerebral Infarction score of ≥2b was achieved in 46 (95.8%) patients. Five patients had wrist access site hematomas. All hematomas resolved with warm compresses, and no further intervention was required. CONCLUSIONS Sheathless radial access using a balloon guide catheter may be safely performed for acute ischemic stroke with excellent radiographic outcomes. Further investigation is warranted to evaluate the comparative effectiveness of sheathless compared with sheathed transradial balloon guide access.

Abstract
Mechanical thrombectomy for acute ischemic stroke (AIS) is traditionally performed via transfemoral access. While the majority of AISs are due to anterior circulation large vessel occlusions (AC-LVO), we performed a systematic review and meta-analysis to examine the feasibility of and outcomes following a transradial artery access for posterior circulation large vessel occlusion (PC-LVO) strokes. A systematic literature review of the English language literature was conducted using PubMed, MEDLINE, and Embase as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcomes of interest included 90-day modified Rankin scale (mRS) 0-2, puncture to recanalization time, and thrombolysis in cerebral infarction (TICI) scores 2b/3 and 3. We calculated pooled event rates and their corresponding 95% confidence intervals (CI) for all outcomes. We included seven studies with 68 patients in our analysis. All patients underwent mechanical thrombectomy via transradial artery access for AIS due to PC-LVO. The pooled meantime of puncture to recanalization was 29.19 (95% CI=24.05 to 35.42) minutes. Successful recanalization (TICI2b/3) was achieved in 98.69% (95% CI=93.50 to 100) of patients and complete recanalization (TICI 3) in 52.16% (95% CI=34.18 to 79.60) of the patients. Overall, 56.84% (95% CI=41.26 to 78.30) of patients achieved mRS 0-2. Transradial artery access for mechanical thrombectomy for PC-LVO stroke displays early promise and feasibility, particularly regarding very high rates of successful recanalization and low puncture to recanalization time.

Abstract
Mechanical thrombectomy (MT) for ischemic stroke due to large vessel occlusion is standard of care. Evidence-based guidelines on eligibility for MT have been outlined and evidence to extend the treatment benefit to more patients, particularly those at the extreme ends of a stroke clinical severity spectrum, is currently awaited. As patient selection continues to be explored, there is growing focus on procedure selection including the tools and techniques of thrombectomy and associated outcomes. Artificial intelligence (AI) has been instrumental in the area of patient selection for MT with a role in diagnosis and delivery of acute stroke care. Machine learning algorithms have been developed to detect cerebral ischemia and early infarct core, presence of large vessel occlusion, and perfusion deficit in acute ischemic stroke. Several available deep learning AI applications provide ready visualization and interpretation of cervical and cerebral arteries. Further enhancement of AI techniques to potentially include automated vessel probe tools in suspected large vessel occlusions is proposed. Value of AI may be extended to assist in procedure selection including both the tools and technique of thrombectomy. Delivering personalized medicine is the wave of the future and tailoring the MT treatment to a stroke patient is in line with this trend.

Abstract
Access techniques for mechanical thrombectomy normally include percutaneous puncture of the common femoral or, more recently, the radial artery. Although target vessel catheterization may frequently not be devoid of difficulties via both routes, the vast majority of mechanical thrombectomy (MT) cases can be successfully managed. However, in a significant minority of cases, a stable target vessel access cannot be reached resulting in futile recanalization procedures and detrimental outcomes for the patients. As such, in analogy to direct carotid puncture for anterior circulation MT, direct vertebral artery (VA) puncture (DVP) is a direct cervical approach, which can constitute the only feasible access to the posterior circulation in highly selected cases. So far, due to the rarity of DVP, only anecdotal evidence from isolated case reports is available and this approach raises concerns with regard to safety issues, feasibility, and technical realization. We present a case in which bail-out access to the posterior circulation was successfully obtained through a roadmap-guided lateral direct puncture of the V2 segment of the cervical VA and give an overview of technical nuances of published DVP approaches for posterior circulation MT.

Transradial versus transfemoral access for acute stroke endovascular thrombectomy: a 4-year experience in a high-volume center. Neuroradiology 2021; 64:999-1009.

Abstract
PURPOSE To compare clinical outcomes and safety of transradial (TRA) versus transfemoral access (TFA) for endovascular mechanical thrombectomy in acute stroke patients. METHODS Retrospective analysis of 832 consecutive patients with acute stroke undergoing interventional thrombectomy using TRA (n = 64) or TFA (n = 768). RESULTS Direct TFA failures occurred in 36 patients, 18 of which underwent crossover TFA to TRA, while direct TRA failures occurred in 2 patients having both crossovers to TFA. Successful catheterization was achieved in 96.8% (62/64) and 95.3% (732/768) of patients undergoing direct TRA and direct TFA, respectively, without significant differences. The median (IQR) catheterization time was 10 (8-16) min in the direct TRA group and 15 (10-20) in the direct TFA group (P < 0.001). This difference was also significant in the subgroup of anterior circulation strokes and in patients younger and older than 80 years of age. The majority of procedures yielded thrombolysis in cerebral infarction grade 2b/2c/3 revascularization in patients undergoing direct TRA (88.5%) and direct TFA (90.8%), without statistically significant differences. The median (IQR) puncture to recanalization time was 37 (24-58) min for the direct TRA group and 42 (28-70) min for the direct TFA group. Significant differences in access site complications, symptomatic ICH, and mRS score 0-2 at 90 days between both TRA and TFA accesses were not found. CONCLUSIONS TRA is not inferior to TFA in the probability of catheterization, times of catheterization and revascularization, and other clinical outcomes for mechanical thrombectomy in acute stroke.

Abstract
BACKGROUND Transradial access (TRA) has gained increased usage among neurointerventionalists. However, the overall safety profile of access site complications (ASCs) and non-access site complications (NASCs) of TRA versus transfemoral access (TFA) for neuroendovascular procedures remains unclear. METHODS A systematic literature review and meta-analysis using a random effects model was conducted to investigate the pooled odds ratios (OR) of ASCs and NASCs. Randomized, case-control, and cohort studies comparing access-related complications were analyzed. An assessment of study heterogeneity and publication bias was also completed. RESULTS Seventeen comparative studies met the inclusion criteria for final analysis. Overall, there was a composite ASC rate of 1.8% (49/2767) versus 3.2% (168/5222) for TRA and TFA, respectively (P<0.001). TRA was associated with a lower odds of ASC compared with TFA (OR 0.42; 95% CI 0.25 to 0.68, P<0.001, I2=31%). There was significantly lower odds of complications within the intervention and diagnostic subgroups. For NASC, TRA had a lower composite incidence of complications than TFA at 1.2% (31/2586) versus 4.2% (207/4909), P<0.001). However, on meta-analysis, we found no significant difference overall between TRA and TFA for NASCs (OR 0.79; 95% CI 0.51 to 1.22, P=0.28, I2=0%), which was also the case on subgroup analysis. CONCLUSION On meta-analysis, the current literature indicates that TRA is associated with a lower incidence of ASCs compared with TFA, but is not associated with a lower rate of NASCs.

Abstract
BACKGROUND The effectiveness of transradial stroke thrombectomy has been limited by guide catheter size and lack of good balloon options. In this study we describe our technique for the use of a sheathless 8-French balloon guide catheter (Walrus) through radial access and present our initial clinical experience. METHODS This was a retrospective case series of consecutive patients who underwent mechanical thrombectomy for large vessel occlusion using the sheathless catheter over a period of 3 months. Clinical characteristics, procedural details, reperfusion success (modified Thrombolysis in Cerebral Infarction (mTICI) 2b-3 grade), first-pass effect (FPE; mTICI reperfusion grade 2c or 3 with a single pass), access site complications and clinical improvement at discharge were recorded. A descriptive analysis was performed. RESULTS Among the 10 patients in the series, median age was 77 years (IQR 75-79) and three were women. All patients had a baseline modified Rankin Scale score ≤2. Median admission National Institutes of Health Stroke Scale (NIHSS) score was 12.5 (IQR 9-16). Four patients received intravenous alteplase before mechanical thrombectomy. Eight patients had M1 occlusion and two had proximal M2 occlusion. The median radial artery diameter was 2.5 mm (IQR 2.5-2.7). Successful reperfusion was achieved in all patients. FPE was achieved in six patients. No access site-related complications or post-procedural intracranial hemorrhages occurred. All patients had improvement in NIHSS score at discharge. CONCLUSIONS The use of this sheathless catheter for transradial access was safe and feasible. The technique can potentially improve the outcomes of transradial access for stroke intervention.

Abstract
Thrombectomy devices played an important role in the success of endovascular treatment trials over the past five years. A balloon guide catheter (BGC) is an adjunctive device used to arrest and reverse flow by inflating the balloon at its tip, which allows for flow reversal in intracranial arteries during retrieval of thrombectomy devices by applying concomitant aspiration through its lumen. Thereby, it can decrease the risk of clot fragmentation and distal embolization. Despite the numerous benchtop and clinical observational studies showing the superiority of BGC to conventional guide catheters in improving reperfusion quality and clinical outcome, its use is still low in clinical practice. The reasons behind this reluctance might be related to technical and cost issues. Therefore, high level evidence data, i.e., a randomized clinical trial, are needed to increase its implementation in thrombectomy procedures. Nonetheless, several obstacles and challenges can prevent the completion of such a trial, and efforts are needed to overcome them. We provide an overview of the current opinions about BGCs in the neurointerventional community and discuss the feasibility and challenges of a possible randomized trial to answer the question "should a BGC be routinely used in endovascular treatment of acute ischemic stroke?"
