Dural Arteriovenous Fistula Treated with Transvenous Embolization via the Upper Limb Cutaneous Vein.

In recent years, the transradial artery approach has gained prominence and is increasingly employed in neurovascular angiography and therapy due to its safety, reduced complications, and minimal invasiveness. While various venous approaches, including the conventional transfemoral vein approach, exist for procedures such as transvenous embolization, recent reports have highlighted methods involving upper extremity cutaneous veins. However, the practicality and efficacy of these approaches remain unclear. This study presents our experience with three cases of dural arteriovenous fistulas, where transvenous embolization was performed via upper limb cutaneous veins. In all instances, the arteriovenous approach was successfully executed using a single upper extremity, leading to the successful completion of treatment. This technique demonstrates significant advantages, not only in terms of its minimal invasiveness but also due to its simplicity and safety. Anticipating broader acceptance in the future, this approach offers a promising avenue for further exploration in neurovascular interventions.

Distal Trans-Radial Artery Approach for Left Main Coronary Artery PCI: Feasibility and Safety

Distal Trans-Radial Artery Approach for Left Main Coronary Artery PCI: Feasibility and Safety

Transradial access with intra-aortic catheter looping for the treatment of intracranial aneurysms.

The study aimed to investigate the feasibility and effect of transradial access with intra-aortic catheter looping for the treatment of intracranial aneurysms. This retrospective one-center study was performed on patients with intracranial aneurysms which were embolized through transradial access with intra-aortic catheter looping because of the difficulty of transfemoral access or transradial access without intra-aortic catheter looping. The imaging and clinical data were analyzed. A total of 11 patients were enrolled, including seven (63.6%) male patients. Most patients were associated with one or two risk factors of atherosclerosis. There were nine aneurysms in the left internal carotid artery system and two aneurysms in the right internal carotid artery system. All 11 patients had complications with different anatomic variations or vascular diseases, which made endovascular operation via the transfemoral artery difficult or a failure. The right transradial artery approach was adopted in all patients, and the success rate of intra-aortic catheter looping was 100%. Embolization of intracranial aneurysms was successfully completed in all patients. No instability of the guide catheter was encountered. No puncture site complications or surgical-related neurological complications occurred. Transradial access with intra-aortic catheter looping for embolization of intracranial aneurysms is technically feasible, safe, and efficient as an important supplementary approach to the routine transfemoral access or transradial access without intra-aortic catheter looping.

Comparative Analysis of Transradial and Transfemoral Arterial Approach When Performing Diagnostic Coronary Angiography.

The transfemoral (TF) arterial approach is still the most commonly used approach for performing diagnostic coronary angiography in most centers in the world as well as in Bosnia and Herzegovina. Recently, the transradial (TR) arterial approach has gained more and more supporters among interventional cardiologists. The aim of the study was to compare the duration of the procedure, the amount of delivered ionizing radiation, the amount of applied contrast agent, the frequency of procedural complications and patient comfort during coronary angiography performed via TR and TF arterial approach. The total sample of 240 respondents was divided into two groups in such a way that the first group consisted of 121 respondents who underwent coronary angiography using TR arterial approach, and the second group consisted of 119 respondents who underwent coronary angiography using TF arterial approach. The Mann-Whitney U test was used to verify the research objective. The obtained research results showed that the duration of coronary angiography and the amount of radiation was greater when using TR arterial approach compared to TF approach. There is no statistically significant difference in relation to the amount of applied contrast medium and the frequency of complications between the two approaches. Periprocedural and postprocedural comfort was better in patents who underwent TR approach. The findings of this study show that diagnostic coronary angiography performed via the TR arterial approach is as safe for the patient as diagnostic coronary angiography performed via the TF arterial approach. With both approaches, there is no significant difference in the amount of contrast agent used nor in the frequency of complications. Procedure duration and radiation exposure are shorter when TF arterial approach i used, while patient comfort is better when the TR arterial approach is used.

Effects of different puncture approaches on the curative effect and safety of patients with combined cardiovascular and cerebrovascular angiography.

The relationship between different puncture points and perioperative complications and length of stay in hospital (LOS) in SCCAG patients has rarely been reported. To compare the curative effect and safety of the transradial artery approach and the transfemoral artery approach in combined heart-brain angiography. 120 patients who received combined cardio-cerebral angiography in our hospital were selected and divided into a transradial artery approach group (TRA) and a transfemoral artery approach group (TFA) according to a random number table. The postoperative efficacy and safety of the 2 groups were compared. There was no statistically significant difference in puncture time and operation time between the 2 groups (p > 0.05). Postoperative bed rest time, hospitalization time, and X-ray exposure time in the TRA group were shorter than those in the TFA group, and the difference was statistically significant (p < 0.05). Before operation and 3 days after operation, there was no significant difference in left ventricle ejection fraction between the 2 groups (p > 0. 05). The overall incidence of complications in the TFA group was higher than that in the TRA group. The incidence between haematoma and pseudoaneurysm in the TFA group was higher, and the difference was statistically significant (p < 0.05). For simultaneous heart-brain angiography, interventional therapy via radial artery and femoral artery has good curative effect and can improve cardiac function. However, interventional therapy through the radial artery can shorten the postoperative bed rest time and hospitalization time, and reduce the incidence of complications.

Distal radial artery approach is safe and effective for cerebral angiography and neuroendovascular treatment: A single-center experience with ultrasonographic measurement.

The transradial artery approach to cerebral angiography can reduce both patient stress following examination and the risk of major complications due to hematoma. Recently, the distal radial artery approach (DRA) has garnered attention in cardiology as a minimally invasive method. DRA is also considered applicable to neurosurgery, although concerns about procedural difficulty and complications persist. Therefore, this study aimed to evaluate the efficacy of the DRA in cerebral angiography and neuroendovascular treatment. We retrospectively selected 30 consecutive patients for whom the DRA was attempted for cerebral angiography at our hospital. The patients' age, sex, height, weight, and medical history information was collected and correlated with successful puncture and complications. The diameter of the distal radial artery (RA) was measured using ultrasonography. The median patient age was 67 years (range, 32-87 years) and 21 (70%) were men. The median diameter of the distal RA was 2.3 mm (range, 1.7-3.2 mm). Distal RA puncture was successful in 23 patients (77%) and no complications were noted; however there was no significant correlation between successful puncture and any of the patient factors. Carotid artery stenting and preoperative tumor embolization were performed via DRA in six and three cases, respectively. Although puncture site hematoma occurred in only one case, all treatments were successful, and no major complications were observed. DRA can be safely used for cerebral angiography and neuroendovascular treatment.

Effect of Thin-Walled Radial Sheath for Large-Bore Access On Reducing Periprocedural Radial Artery Occlusion Following Complex PCI: The REDUCE-RAO Randomized Trial.

Transradial artery (TRA) access for percutaneous coronary intervention (PCI) was associated with lower risks of major bleeding and vascular complications compared to transfemoral artery access. Use of large-bore ( 7-Fr) guiding catheters through TRA approach increased the likelihood of radial artery occlusion (RAO). This study aimed to investigate whether use of the thin-walled 7-Fr Glidesheath Slender, allowing PCI with large-caliber guiding catheters, is superior to standard 7-Fr Cordis sheath with respect to periprocedural RAO within 24 hours after transradial coronary intervention (TRI) in complex lesions. A prospective randomized, controlled, single-blinded (patient-blinded) trial was conducted, randomizing 504 patients with TRI for complex lesions to either 7-Fr Glidesheath Slender or conventional 7-Fr Cordis sheath. The primary outcome was defined as the incidence of periprocedural RAO with Doppler ultrasound during the first 24 hours after TRI. The incidence of early RAO was 10.3% for 7-Fr Glidesheath Slender and 13.5% for conventional 7-Fr sheath (p = 0.271). The procedural success rate for Glidesheath Slender was 92.9% and for Cordis sheath was 93.7% (p = 0.722). There was no signficiant difference between treatment arms in terms of local hematoma and radial spasm, whereas use of the Glidesheath Slender was associated with significantly less pain during the procedure (numeric rating scale [NRS], 2.27 0.75 vs. 2.45 0.95, p = 0.017). The assessment of radial artery in ultrasound parameters after complex TRI was improved with Glidesheath Slender. Among patients with complex coronary lesions undergoing TRI, 7-Fr Glidesheath Slender was not superior to conventional 7-Fr in the prevention of periprocedural RAO within 24 hours following complex PCI, without reducing RAO occurrence.

Safety and Efficacy of Radial Versus Femoral Artery Access for Mechanical Thrombectomy Procedures Following Intravenous Administration of Tissue Plasminogen Activator

BackgroundThe transradial artery (TRA) approach for neuroendovascular procedures is a safe and effective alternative to the transfemoral artery (TFA) approach. We compared the efficiency and periprocedural outcomes of TRA and TFA approaches for acute stroke interventions in patients receiving intravenous tissue plasminogen activator.MethodsA retrospective cohort study analyzed data from patients at a large cerebrovascular center from January 1, 2014, to March 31, 2021. Baseline characteristics, periprocedural efficiency and efficacy, and in‐hospital outcomes were compared between intervention cohorts (TRA and TFA).ResultsOf 314 patients analyzed, 21 (7%) underwent a TRA approach and 293 (93%) underwent a TFA approach. Complications occurred in one (5%) of 21 patients in the TRA cohort and 20 (7%) of 293 patients in the TFA cohort. Access site complications were present in 12 (4%) patients with TFA, and no patients with TRA experienced access site complications. The mean length of stay was significantly longer for the TFA cohort (8.8 days [standard deviation, 8.5 days]) versus the TRA cohort (4.8 days [standard deviation, 2.9 days]) (P=0.02). Linear regression analysis showed that femoral access, Medicaid insurance, and discharge National Institutes of Health Stroke Scale score &gt;10 predicted longer length of stay (P≤0.046). However, when the time to initial physical or occupational therapy session was added to the model, access site was no longer significant (P=0.42).ConclusionThe TRA approach may reduce periprocedural complications and hospital length of stay compared with the TFA approach. The shorter length of stay associated with TRA access appeared to be associated with earlier initiation of physical or occupational therapies.

THE INFLUENCE OF THE PATIENT'S AGE ON THE DURATION OF THE PROCEDURE AND THE AMOUNT OF RADIATION DELIVERED WHEN PERFORMING DIAGNOSTIC CORONARY ANGIOGRAPHY

The aim of the research was to determine whether the age of the patient affects the duration of the procedure and the amount of ionizied radiation delivered when performing diagnostic coronary angiography. The research was conducted at the Clinic for Invasive Cardiology of the Public Health Institution "University Clinical Center" Tuzla in the period from December 2018. to January 2020. The research included a total sample of 240 respondents, average chronological age of 62.60 ± 9.22 years, ranging from 24 to 85 years. Out of a total of 240 respondents, in 121 respondents coronarny angiography was performed using transradial arterial approach and 119 by performing a transfemoral arterial approach. The total sample was divided into two subsamples of respondents. The first sub-sample consists of respondents up to 65 years of age, and the second sub-sample consists of respondents over 65 years of age. During each performance of coronary angiography, the duration of the procedure (in minutes and seconds) and the amount of radiation delivered during the procedure (in mGy) were measured. The research data were processed using the method of parametric and non- parametric statistics. The Mann-Whitney U test was used to verify the research objective. Based on the obtained research results, it can be concluded that in patients over 65 years of age, the duration of the coronary angiography procedure is longer, and is at the limit of statistical significance (p= 0.057). The amount of delivered radiation is higher in respondents over 65 years of age, but it is not statistically significant (p= 0.396). Keywords: Coronary angiography, coronary disease, procedure duration, age, amount of delivered radiation.

Transradial Artery Approach for Diagnostic Coronary Angiography: Immediate Clinical and Procedural Outcome

Background: The transradial approach has emerged as an attractive alternative to the femoral approach for coronary angiography. In the hands of experienced operators, transradial coronary angiography offers improved patient comfort and decreased access-site complications. Objectives: To evaluate the immediate clinical &amp; procedural outcome of transradial approach for coronary angiography. Methodology: This is a descriptive cross sectional study carried out in a tertiary cardiac center .The transradial approach was attempted in patients with a good radial pulse and normal Allen test. This study enrolled 70 patients who underwent coronary angiography during the period from October 2012 to April 2013. Result: The transradial approach was attempted in 70 Patients. The preferred side for transradial approach was the right side in all cases. The procedure success was 91.4%. Failure of puncture or canulation of the radial artery was the main cause of failure rate, followed by subclavian tortuosity and radial artery spasm. No minor or major vascular complications due to the procedure apart from one patient (1.4%) who got small superficial hematoma in the forearm. The average time for successful canulation was 4.8± 3.9 min (range 3.3 to 8.1 minutes), and that of the catheterization procedure was 33.12 ± 11.2 minutes (range 20-60 min.). Conclusion: The transradial approach for coronary angiography is a safe and effective alternative to femoral approach. Keyword: Transradial approach; coronary angiography.

Safety and Feasibility of Ultrasound-Guided Access for Coronary Interventions through Distal Left Radial Route.

Aims Left distal transradial arterial approach (ldTRA) is a new interventional route that spares right radial artery (RRA) for use in haemodialysis and as bypass graft. Vasant Kunj Left dIstal Transradial ArtEry approach (VKLITE) study aimed to assess the feasibility and safety of ldTRA access during coronary angiography (CAG) and percutaneous coronary intervention (PCI). Methods and Results Between April 2018 and June 2020, 108 patients were enrolled and underwent CAG ± PCI via ultrasound guided ldTRA. Arterial puncture, CAG, and PCI were successful in 96.3% (104/108), 92.1% (93/101), and 94.1% (32/34) patients, respectively. Access site crossover rate was 14/108 (13.0%). Mean puncture, procedure, and haemostasis time (minutes) were 6.7 ± 7.1, 55.7 ± 32.8, and 23.1 ± 11.9. Median total fluoroscopic time was 6.6 minutes (IQR-14.2), and median total radiation dose was 39.2 Gy-cm2 (IQR-97.0). Local haematoma occurred in 11 patients (10.2%) with major haematoma in 1.9%, all recovering within three weeks. Mean pain score was 2.4 ± 2.3, and patient satisfaction score was 9.0 ± 1.3. LdTRA access compared with RRA access (n = 121) showed significantly increased mean procedure time (55.7 ± 32.8 vs. 43.9 ± 26.0 minutes, p = 0.01) and median total fluoroscopic time (6.6 [IQR-14.2] vs. 4.7 [IQR-8.2] minutes, p = 0.02), with similar median total radiation dose (39.2 [IQR-97.0] vs. 43.8 [IQR-54.5] Gy-cm2, p = 0.56). No radial artery loss, dissection, pseudoaneurysm, arteriovenous fistula, or nerve injury was noted. Conclusions LdTRA access is feasible with few complications during CAG/PCI. Patient comfort and satisfaction makes it a desirable route for coronary interventions.

Clinical Efficacy of the Transradial Approach in Percutaneous Intervention for a Malfunctioning Arteriovenous Fistula.

PurposeTo evaluate the effectiveness of the transradial artery approach (TRA) for treating malfunctioning arteriovenous fistulas (AVFs) in patients on hemodialysis.Materials and MethodsA retrospective analysis was conducted in this single-center study of TRA endovascular procedures in 73 patients (43 male and 30 female; mean age of 67.4 years (range, 42–92 years) with malfunctioning AVFs, between January 2008 and April 2019. Patients’ baseline and lesion characteristics, technical and clinical success, and complications were evaluated, and functional patency was analyzed using the Kaplan-Meier method.ResultsRadial artery approaches were successful in all patients. Angioplasty performed using the TRA achieved technical and clinical success rates of 98.6%(72/73) and 91.7%(67/73), respectively. The median primary patency time was 18.8 ± 15.9 months. The primary functional patency rates at 3, 6, and 12 months were 82.1%, 68.6%, and 63.9%, respectively. There were no major complications or adverse events, such as hand ischemia, related to the radial artery approach.ConclusionIn selected cases, the TRA can be used complementary to the transvenous approach to treat malfunctioning AVFs.

Abstract P539: Comparison of Transradial Artery versus Transfemoral Artery Access for Solumbra Technique in Mechanical Thrombectomy

Introduction: Solumbra technique involves the simultaneous use of stent-retriever and large-bore aspiration for clot retrieval in mechanical thrombectomy (MT). We aim to compare various time parameters in patients who undergo MT via solumbra technique via transradial artery (TRA) approach vs. transfemoral artery (TRF) approach. Methods: We performed a retrospective chart review of patients who underwent MT via solumbra technique for anterior circulation large vessel occlusion at a comprehensive stroke center from 7/2014 to 5/2020. We compared time to recanalization parameters, score of TICI≥2b, and functional independence (3-month mRS≤2) in patients who underwent MT via TRA vs.TRF approach via the solumbra technique. A binary logistic regression analysis was performed, controlling for age, sex, pre-treatment-NIHSS, type of anesthesia (general vs.moderate), laterality, and clot location [proximal (internal carotid or M1 segment of the middle cerebral artery) vs.distal (M2 or M3 segment of the middle cerebral artery)]. Results: A total of 98 patients met our inclusion criteria. The mean age was 63.59±14.40 years. 18 (18.37%) patients underwent MT through transradial approach. In our cohort, there was a significant association of TRA with shorter angio suite arrival-time to puncture-time (22.12±9.92mins vs.28.83±12.26mins; OR, 0.94; 95% CI, 0.88-1; P 0.026), but not with puncture-time to recanalization-time (84.34±61.34mins vs.63.73±35.29mins; OR, 1.01; 95% CI, 1-1.03; P 0.085), angio suite arrival-time to recanalization-time (103.12±51.29mins vs.93.42±39.08mins; OR, 1.01; 95% CI, 1-1.02; P 0.524), number of passes to recanalization (1.78±1.36 vs.1.68±1.05; OR, 1.03; 95% CI, 0.66-1.63 ; P 0.899), number of patients with TICI≥2b (83.34% vs.91.25%; OR, 0.68; 95% CI, 0.14-3.4; P 0.633), and functional independence (66.67% vs.78.75%; OR, 0.49; 95% CI, 0.13-1.86; P 0.292), when compared to TRF approach for MT using solumbra technique. Conclusion: Our study demonstrates a significant association between TRA approach with shorter angio suite arrival-time to puncture-time but not with overall time to recanalization, number of patients with TICI≥2b, and functional independence, when compared to TRF approach for MT using solumbra technique.

Feasibility and Safety of the Distal Transradial Artery for Coronary Diagnostic or Interventional Catheterization.

Background This prospective study compared the success rate and safety of a distal transradial artery (dTRA) approach to that of the conventional transradial artery (TRA) for coronary angiography or percutaneous coronary intervention. Methods From January 2019 to April 2020, nine hundred consecutive patients (height < 190 cm) scheduled for coronary angiography or percutaneous coronary interventions were randomly and equally assigned to receive either dTRA or conventional TRA catheterization. Results Successful access was achieved in 96.00% and 96.67% of the dTRA and conventional TRA groups, respectively (P=0.814). Compared with the TRA group, patients in the dTRA experienced significantly less hemostatic band removal time (150.5 ± 50.5 cf. 210.6 ± 60.5 min, P=0.032); minor bleeding of the access site (2.44% cf. 6.44%, P=0.038); hemostatic band cost (USD; 0.1 cf. 59.4, P=0); and postprocedural radial artery occlusion (1.56% cf. 3.78%, P=0.035). A lower body mass index was a higher risk factor for dTRA access failure (odds ratio = 0.79, P=0.024), with a cutoff of 22.04 kg/m2. Conclusion Compared to conventional TRA, dTRA had a comparable high success rate, with fewer associated complications. Clinicians should use the dTRA with caution in patients with low body mass index.

Distal radial approach via anatomical snuffbox is associated with higer rate of radial spasm and greater patient discomfort

Abstract Background/Introduction Conventional transradial approach (c-TRA) at the wrist is considered as the default strategy for catheter-based procedures providing less serious access-related complications and better patients' comfort than transfemoral route. A novel distal transradial artery approach (d-TRA) via the anatomical snuffbox has been proposed recently as an noteworthy alternative. It is hypothesised that d-TRA may provide additional benefits without losing the efficacy of c-TRA. Purpose To assess consecutive patients' comfort undergoing coronary angiography or intervention by novel d-TRA in comparison with c-TRA. Methods In a span of 4 months, out of 465 caucasian subjects, 400 patients were included in a prospective, single-center, randomized (1:1) distAl vs traditioNal Transradial Access for coRonary procEdures Study (ANTARES). Hemodynamic instability, ST-elevation myocardial infarction, forearm artery occlusion or prior radial access failure were the exclusion criteria. An artery was punctured with anterior wall modified Seldinger technique, and standard 5F or 6F vascular sheaths were used. Pain/discomfort when access gaining, radial spasm, early (within 24 hours) postprocedural local neuropathy (thumb numbness) were the analyzed parameters determining patients' comfort in both groups. Results Baseline characteristics of patients were matched. Conclusion(s) Coronary procedures performed in consecutive patients via novel d-TRA are associated with worse patient's comfort determined by higer rate of radial spasm and early postprocedural local neuropathy, and greater pain/discomfort when access gaining, in comparison with c-TRA.

Percutaneous trans-ulnar versus trans-radial arterial approach for coronary angiography and angioplasty, a preliminary experience at an Egyptian cardiology center

BackgroundTrans-ulnar approach was proposed primarily for elective procedures in patients not suitable for trans-radial approach that was introduced two decades ago. The trans-ulnar approach is as safe and effective as the trans-radial approach for coronary angiography and intervention.AimThis study’s aim was to assess the feasibility and safety of the trans-ulnar approach in coronary procedures as a preliminary experience for operators experienced in trans-radial approach with no/minimal trans-ulnar approach experience at an Egyptian center.ResultsVascular access in 120 patients was selected randomly for coronary angiography and angioplasty—80 through radial and 40 through ulnar approach. Patients were examined for local complications and Doppler evaluation to both radial and ulnar arteries a day after the procedure was done. Ulnar approach success was 82.5% versus 93.7% in the radial group; failure of ulnar artery puncture was the only cause of crossover in the ulnar group, while occurrence of persistent spasm was the leading cause of crossover in the radial group followed by radial artery tortuosity. The procedure time of coronary angiography and percutaneous coronary intervention of the ulnar group was significantly higher than that of the radial group (P value = 0.011 and 0.034, respectively). The mean caliber of the right ulnar artery was 2.45 ± 0.38, slightly larger than that of the radial artery 2.33 ± 0.38 at the level of the wrist, but this difference was statistically non-significant.ConclusionOur study demonstrated that ulnar access with experienced radial operators and in our patients is a safe and practical approach for coronary angiography or angioplasty, without any major complications. Bearing in mind its high success rate, it can be used when a radial artery is not useful for the catheterization or as a default approach on the expense of slightly longer procedural time.

Radial artery occlusion after cardiac catheterization and impact of medical treatment.

Background: The transradial artery approach is the preferred access for cardiac catheterization according to current guidelines. However, the most common complication is radial artery occlusion (RAO). Despite the rare indication for surgical reopening, the occluded radial artery is not available for further procedures or as a potential bypass graft. Still, treatment regimens for RAO are scarce. We now determined whether the addition of antithrombotic to antiplatelet therapy improves the rate of partial or complete regain of patency in RAO following transradial cardiac catheterization in a retrospective analysis. Patients and methods: In a two-center tertiary referral hospital retrospective analysis 4135 files of patients who had undergone transradial catheterization were screened for documented RAO. 141 patients were identified and 138 patients with complete information on the medical regimen and ultrasound examinations for a maximum of 3 months were included in the analysis, whereas 3 patients were excluded due to missing or incomplete follow-up information. Results: 3.3% of all patients that had undergone transradial catheterization featured an oligosymptomatic RAO, confirmed by color-coded duplex sonography. 21% of patients with additional anticoagulation regained full patency vs. 9% without additional anticoagulation (p=0.07). 40% of patients with anticoagulation featured a partial or full regain of patency vs. 16% of patients without additional anticoagulation for a maximum of 3 months treatment (p=0.006). No major bleedings were reported during the follow-up visits. Conclusions: RAO remains a rare complication of cardiac catheterization. The addition of antithrombotic therapy for 3 months appears to safely improve the partial or even full regain of radial patency in case of postinterventional RAO.
