Upper Extremity Function Following Transradial Percutaneous Coronary Intervention: Results of the ARCUS Trail

Background: Regardless of the recent rise in the number of articles published on transradial access (TRA) for diagnostic coronary intervention and complications of the upper extremity may be underestimated. The aim of this study to investigate the prevalence of upper extremity disorder by comparing the transradial and transfemoral artery percutaneous coronary intervention (TR-PCI). Study Design: This was cross-sectional study and conducted in the Ayub teaching hospital Abbotabad, for six months July 2022 to December 2022. Materials and Methods: The total participants were 250 which included 200 TRA and 50 TFA participants and involving any type of cerdiointervention, thrombectomies for acute ischemic stroke, and carotid artery stents. The participants were selected by sampling technique were interviewed in the Khyber teaching hospital Peshawar. We analyzed dependent and independent variables. Data analysis statistically by SPSS 22 version. The upper extremity scores were analyzed using Chi-squared test. Results: There were total 250 participants which include 80%TRA and 20% TFA in this research. The majority of the participants in TRA were in the age group (59.2±6.7) years and in TFA group (55.5±7.1) years. The baseline characteristics of the total participants was no significant difference between transradial artery (TRA) and transradial femoral artery (TFA). During follow-up, Cochran's Q-test revealed a significant increase in UED in the intervention extremity of the TRA group p=0.003 and in the TFA group's right upper extremity (p=0.001). During follow-up, 1% TRA participants had RAO, which recanalized over time. Three weeks after the procedure, 10% of participants in the TRA group were referred to a hand specialist then TFA participants. Conclusion: Transradial arterial access (TRA) for percutaneous coronary artery intervention has been linked to lower access site complication rates and higher patient satisfaction when compared to transfemoral access (TFA) after 3 weeks follow up. Keywords: Transradial artery (TRA), Transfemoral artery (TFA), Rotational acetabular osteotomy (RAO).

Post-Transcatheter Aortic Valve Replacement (TAVR) Vascular Complications: Femoral Artery Minimal Surgical Access Versus Percutaneous Approach.

Percutaneous transfemoral access approach for the transcatheter aortic valve implantation (TAVI) is still associated with significant vascular complications. Hence, evaluation of best techniques for the reduction of vascular injury via the femoral access remains a key subject of research. We report on a single centre's experience with TAVI performed via the Femoral Artery Minimal Surgical Access (MSA) and percutaneous approach (PC). The primary endpoints were to evaluate the incidents of vascular complications by comparing the MSA versus the PC approach according to the VARC-2 criteria. The secondary endpoint included the impact of vascular complications on the in-hospital 30-day mortality and morbidity. Between June 2010 and September 2020, two hundred and thirty-seven consecutive patients who underwent TAVI for severe symptomatic aortic stenosis in our department were divided into two groups: patients treated using the femoral artery minimal surgical access (n = 173), and patients treated using the percutaneous approach (n = 64). Overall rate of access site complications according the VARC-2 were significantly more frequent in the percutaneous cohort (n = 12/64, 18.8% vs n = 2/173, 1.1%, p = 0.0012). The minor access complications including haematoma, bleeding, aneurysm, dissection, stenosis, seroma and infection were more frequent in the PC group (n = 8/64, 12.5% vs n = 2/173, 1.1%, p < 0.001). There were no major access site complications and hospital deaths in the MSA group, which was statistically significant (p < 0.001). Major access complications (n = 4, 6.3%, p < 0.001) and hospital death (n = 2, 3.1%, p < 0.001) were found in the PC cohort. The minimal surgical access approach provided direct and controlled access and significantly reduced the incidence of access site vascular complications in our TAVI patients. It also significantly reduced the in-hospital vascular-related mortality and morbidity. Though both approaches are complementary to each other, minimal surgical access approach would be a better choice for a calcified or tortuous femoral artery, and for a relatively small femoral artery diameter.

Gender Influence on In-hospital Outcomes of Primary Percutaneous Coronary Intervention

Background: Acute myocardial infarction (AMI) is one of the leading cause death and disability all over the world. But, there is a lack of data about the gender influence on in-hospital outcomes of primary percutaneous coronary intervention (pPCI) among Bangladeshi patients. This study was aimed to evaluate the clinical and angiographic differences and to compare their in hospital outcomes of pPCI between male and female patients. Objective: To evaluate the gender influence on in-hospital outcome of primary PCI. Methods: This was a prospective observational study of 90 patients with ST elevation myocardial infarction ( STEMI ) treated with pPCI in the Department of Cardiology, NICVD, Dhaka, Bangladesh from April 2019 to March 2020, followed from admission until hospital discharge or death. The patients were divided equally into two groups, group ‘! (female) and group a! (male). Result : A significant difference was observed for age (61.8±10.9vs.56.5±10.7 years; p=0.02), hypertension (66.7% vs. 42.2%; p=0.02), diabetes (68.9% vs. 44.4%; p=0.01), smoking (0.0% vs. 68.9%; p&lt;0.001), obesity (BMI- 28.3±3.8 vs. 26.5±3.9; p=0.02), troponin I (14.89±20.48 vs. 8.25±7.92; p=0.04) and pain-to-door time (281.90±88.70 vs. 240.33±80.81 minutes; p=0.04). Female had angiographically greater frequency of multivessel disease and similar distribution of infarct related artery in relation to male. The success of the procedure was similar (91.1% vs. 97.8%; p=0.18). Overall, female experienced greater incidence of in-hospital adverse events in comparison to male (28.8% vs. 13.3%; p=0.03) and significantly higher rates of severe bleeding (11.1% vs.2.2%; p=0.03) and vascular access site complications (15.6% vs. 4.4%; p=0.04). Major adverse cardiac events (MACE) were higher among females in comparison to males (11.1% vs. 6.7%; p=0.45). Females experienced significantly higher rates of short-term net adverse clinical events (NACE) than males (20.0% vs. 8.8%; p=0.04). Female sex [odds ratio (OR) 1.94], age e”60 years (OR 1.59) and diabetes (OR 2.75) were identified as independent predictors of adverse in-hospital outcomes among STEMI patients undergoing pPCI. Conclusion: Female sex presented with significantly more risk factors and experienced more in-hospital adverse outcomes than male in STEMI patients undergoing pPCI. They had significantly higher rates of NACE, largely driven by increased rate of major bleeding. Female sex was an independent predictor for the development of in-hospital adverse outcomes in STEMI patients undergoing pPCI. Bangladesh Heart Journal 2022; 37(1): 40-51

Transbrachial Access Site Complications in Endovascular Interventions: A Systematic Review of the Literature.

The transfemoral approach (TFA) or transradial approach (TRA) serves as the primary technique for most endovascular cases; however, the transbrachial (TBA) route is an alternative access site used when TFA and TRA are contraindicated. Although TBA has advantages over TRA, such as the ability to accommodate large guide catheters and devices, there is some apprehension in implementing TBA due to perceived access site complication rates. This article aims to glean the rate of access site complication from current literature.Relevant studies were identified using the following search terms: ((access site complications) AND ((endovascular AND brachial) OR (percutaneous brachial access) OR (brachial))) OR (endovascular AND (percutaneous brachial access)); endovascular + brachial artery; endovascular + brachial artery + access site; and endovascular + brachial artery + access site complications. Articles published after 2008 addressing major complication rates from percutaneous TBA interventions were included.Fifteen studies out of 992 total articles met the inclusion criteria. The major access site complication rate was 75/1,424 (5.27%). Patients who underwent hemostasis with a vascular closure device (VCD) had a major complication rate of 13/309 (4.21%) compared to a major complication rate of 65/1122 (5.79%) for patients who underwent hemostasis with manual compression (MC).The major access site complication rate associated with TBA was 5.27%, which is relatively high compared to the complication rate in TFA or TRA. More prospective trials are needed to fully understand the access site complication rate in TBA interventions.

Feasibility and Safety of Transradial Aneurysm Embolization: A Systematic Review and Meta-Analysis

Use of the transradial access (TRA) approach for neuroendovascular procedures has been increasing in recent years. Our aim is to assess the feasibility, success rate, and complications associated with TRA for intracranial aneurysm embolization. PubMed, Scopus, and Embase were systematically searched for studies using TRA for intracranial aneurysm embolization. Random-effects models were used to obtain pooled rates of procedural success and complications. Twenty-four studies comprising 1283 (85.9%) TRA and 122 (8.2%) distal TRA aneurysm embolization procedures were included. The pooled success rate of the 18 studies in the meta-analysis was 93.5% (95% confidence interval [CI], 91.1%-95.8%). The pooled thromboembolic complication rate was 0.5% (95% CI, 0.1%-0.9%), the hemorrhagic complication rate was 0.5% (95% CI, 0.1%-0.9%), and the access site complication rate was 0.8% (95% CI, 0.3%-1.3%). One study (4.3%) used exclusively a 7-French guide catheter, and most used a 6-French guide catheter (22 of 23 studies, 95.7%), which was further incorporated as part of a triaxial configuration through a sheathless 8-French system in 4 studies (17.4%), 7-French guide catheter in 2 studies (8.7%), and 8-French sheath in 1 study (4.3%). The embolization techniques used were flow diverter placement in 451 cases (39.1%), coiling in 376 (32.6%), stent-assisted coiling in 127 (11.0%), balloon-assisted coiling in 104 (9.0%), Woven EndoBridge system in 50 (4.3%), and flow diverter placement plus coiling in 42 (3.6%). Treating intracranial aneurysms using various embolization techniques through TRA is feasible and associated with low access site and intraoperative complications.

Abstract No. 117 Effect of preprocedural antiplatelet and anticoagulant use on antegrade access site complication rate during lower extremity peripheral arterial disease interventions

To determine the complication rate of antegrade femoral artery access in patients on anti-platelet and/or anticoagulant medications during peripheral arterial interventions

Abstract No. 517 How many times can a radial artery be accessed?

Radial access has several advantages over femoral access, including lower access site complication rates, reduced periprocedural pain and shorter recovery times. On the other hand, post-procedural arterial occlusion occurs more frequently after radial access compared with femoral access which can be a limitation in patients who require repeat transarterial procedures. Limited data is available regarding how many times a radial artery can be accessed for interventional procedures. The purpose of this study was to evaluate radial artery access in patients who underwent 4 or more transradial procedures via the same radial artery.

Transradial versus Transfemoral Approaches in Diagnostic and Therapeutic Neuroendovascular Interventions: A Meta-Analysis of Current Literature

The adoption of the transradial approach (TRA) has been increasing in popularity as a primary method to conduct both diagnostic and therapeutic interventions. As this technique gains broader acceptance and use within the neuroendovascular community, comparing its complication profile with a better-established alternative technique, the transfemoral approach (TFA), becomes more important. This study aimed to evaluate the safety of TRA compared with TFA in patients undergoing diagnostic, therapeutic, and combined neuroendovascular procedures. A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search of PubMed and other databases was conducted for studies from all available dates. To compare TRA and TFA, we performed an indirect meta-analysis between studies that mentioned the complications of the procedures. Our search yielded 532 studies, of which 108 met full inclusion criteria. A total of 54,083 patients (9137 undergoing TRA and 44,946 undergoing TFA) were included. Access site complication rate was lower in TRA (1.62%) compared with TFA (3.31%) (P < 0.01). Neurological complication rate was lower in TRA (1.64%) compared with TFA (3.82%) (P= 0.02 and P < 0.01, respectively). Vascular spasm rate was higher in TRA (3.65%) compared with TFA (0.88%) (P < 0.01). Wound infection complication rate was higher in TRA (0.32%) compared with TFA (0.2%) (P < 0.01). Patients undergoing TFA are significantly more likely to experience access site complications and neurological complications compared with patients undergoing TRA. Patients undergoing TRA are more likely to experience complications such as wound infections and vascular spasm.

Endovascular treatment of nonfunctional vascular access through retrograde arterial access: A single-center experience with midterm follow-up

Background/Aim: Nonfunctional vascular access is treated through venous or brachial artery access traditionally. However, each route has its drawbacks. This study aimed to evaluate the feasibility, safety, and effectiveness of retrograde arterial access (RAA) in the treatment of nonfunctional vascular access with mid-term results. Methods: Patients with nonfunctional vascular access who were treated through RAA between January 2019 and December 2020 were included in this cohort study. Patient demographics, lesion characteristics, procedural details, technical and clinical outcomes were noted. Results: Thirty-six interventions were performed on 30 patients. Twenty-nine occlusions and seven long segment stenoses were treated. The radial artery was accessed in 34 cases, the interosseous and ulnar arteries were accessed in one case each. The technical and clinical success rates were 100% and 97.2%, respectively (35/36). Venous rupture was encountered in three patients. No puncture-site complication was observed. The mean follow-up time was 14.3 (range: 6-24) months. None of the patients showed signs of hand ischemia and the accessed arteries were patent at Color Doppler Ultrasound examinations. Post-intervention primary patency rates were 100%, 73.3%, 47.5% at 1, 6 and 12 months, respectively. Post-intervention secondary patency rates were 100%, 93.3%, 84.8% at 1, 6 and 12 months, respectively. Conclusion: RAA is effective and safe in the treatment of nonfunctional vascular access with comparable outcomes to traditional routes. The low access-site complication rates make this access site an attractive salvage route when traditional approaches are not feasible.

Distal Radial Secondary Access for Transcatheter Aortic Valve Implantation: The Minimalistic Approach

BackgroundAlthough not yet recommended by the guidelines, distal radial access, a new site for cardiovascular interventions, has been rapidly acknowledged and adopted by many centers due to its high rate of success, safety and fewer complications. We present our experience using secondary distal radial access during transcatheter aortic valve implantation (TAVI), proposing a new, even more minimal approach. MethodsAs of November 2020, a systematic distal radial approach as secondary access site for TAVI was adopted in our center. Primary endpoints were technical success and major adverse events (MAEs). Secondary endpoints: the access site complication rate, hemodynamic and clinical results of the intervention, procedural related factors, crossover rate to the femoral access site, and hospitalization duration (in days). ResultsFrom November 2020, 41 patients underwent TAVI using this strategy. Patients had a mean age of 76 ± 11.2 years, 41% were male. Six (14.63%) patients received a balloon-expandable valve and 35 (85.37%) received a self-expandable valve. TAVI was successful in all cases. No complications occurred due to transradial access. Puncture success, defined as completed sheath placement was maximum (N = 41/41,100%) and emergent transfemoral secondary access was not required in any case. Primary transfemoral vascular access site complications occurred in 7 cases (17%) of which 4 (13.63%) were resolved through distal radial access: one occlusion, two flow-limiting stenoses and four perforations of the common femoral artery. There were no additional major vascular complications at 30 days. Overall MACE rate was 2.4%. ConclusionThe use of the distal radial approach for secondary access in TAVI is safe, feasible and has several advantages over old access sites.

Radial versus femoral access in patients with coronary artery bypass surgery: Frequentist and Bayesian meta-analysis.

The optimal access site for cardiac catheterization in patients with prior coronary artery bypass surgery (CABG) continues to be debated. We performed a random effects frequentist and Bayesian meta-analysis of 4 randomized trials and 18 observational studies, including 60,192 patients with prior CABG (27,236 in the radial group; 32,956 in the femoral group) that underwent cardiac catheterization. Outcomes included (1) access-site complications, (2) crossover to a different vascular access, (3) procedure time, and (4) contrast volume. Mean differences (MD) and 95% confidence interval (CI) were calculated for continuous outcomes and odds ratios (OR) and 95% CI for binary outcomes. Among randomized trials, crossover (OR: 7.63; 95% CI: 2.04, 28.51; p= 0.003) was higher in the radial group, while access site complications (OR: 0.96; 95% CI: 0.34, 2.87; p= 0.94) and contrast volume (MD: 15.08; 95% CI: -10.19, 40.35; p= 0.24) were similar. Among observational studies, crossover rates were higher (OR: 5.09; 95% CI: 2.43, 10.65; p< 0.001), while access site complication rates (OR: 0.52; 95% CI: 0.30, 0.89; p= 0.02) and contrast volume (MD: -7.52; 95% CI: -13.14, -1.90 ml; p= 0.009) were lower in the radial group. Bayesian analysis suggested that the odds of a difference existing between radial and femoral are small for all endpoints except crossover to another access site. In a frequentist and Bayesian meta-analysis of patients with prior CABG undergoing coronary catheterization, radial access was associated with lower incidence of vascular access complications and lower contrast volume but also higher crossover rate.

Efficacy and Safety of Ultrasound-Guided Repeat Access and Repeat Closure With an ExoSeal Vascular Closure System in Patients With Peripheral Arterial Disease.

The purpose of this study was to evaluate the efficacy and safety of ultrasound-guided repeat access and repeat closure with an ExoSeal vascular closure system. A total of 123 endovascular therapy (EVT) procedures were performed in 59 patients (65 limbs) with ultrasound-guided repeat access and repeat implantation of an ExoSeal vascular closure system between January 2019 and March 2021. The procedural details and postprocedural outcomes of EVT with repeat access and use of ExoSeal (RE group) were compared with those of EVT with initial use of ExoSeal (IE group) in the same patients. In a subgroup analysis, these outcomes were also compared in early repeat (within 3months) and late repeat (over 3months) cases. The technical success rate of ultrasound-guided access in the RE group was 100%. The procedural success rate of EVT and deployment success rate of ExoSeal in the RE group were 93% and 94%, respectively, which were not significantly different to those in the IE group. Access site complications in the RE group occurred in 2 cases (2%), again with no significant difference with the IE group. The median puncture, procedural, and hemostasis times in the RE group were 3 [2-5], 36.5 [29-54], and 7 [5-10] min, respectively, which were not significantly longer than those in the IE group. In the RE group, early and late repeat closure was performed in 66 (54%) and 57 (46%) cases, respectively, and there were no significant differences in the technical success of ultrasound-guided access, procedural success of EVT, deployment success of ExoSeal, and access site complication rates in these cases. Ultrasound-guided access facilitated higher technical success of repeat access and fewer access site complications in EVT with repeat use of ExoSeal, regardless of the interval between procedures.

TRIACCESS Study: Randomized Comparison Between Radial, Femoral, and Pedal Access for Percutaneous Femoro-popliteal Artery Angioplasty

Background The aim of this randomized study was to compare the success and complication rates of different access sites for the treatment of superficial artery stenosis. Methods and Results A total of 180 consecutive patients were randomized in a prospective study to treat symptomatic superficial femoral artery stenosis via radial (RA), femoral (FA), or pedal artery (PA) access. Technical success was achieved in 96.7%, 100%, and 100% of the patients in the RA, FA, and PA groups, respectively (p=0.33). Secondary access sites were used in 30%, 3.3%, and 30% of the patients in the RA, FA, and PA access groups, respectively (p=0.0002). Recanalization for chronic total occlusion was performed in 34/36 (94.4%), 30/30 (100%), and 46/46 (100%) patients in the RA, FA, and PA groups, respectively (p=0.17). The X-ray dose was significantly lower in the PA group than that in the RA and FA access groups (63.1 vs 162 vs 153 Dyn, p=0.0004). The cumulative rates of access site complications in the RA, FA, and PA groups were 3.3% (0% major and 3.3% minor), 16.7% (3.3% major and 13.3% minor), and 3.3% (3.3% major and 0% minor) (p=0.0085), respectively. The cumulative incidence of MACEs at 6 months in the RA, FA, and PA groups was 5%, 6.7%, and 1.7%, respectively. The cumulative incidence of MALEs at 6 months in the RA, FA, and PA groups was 20%, 16.7%, and 9.2%, respectively (p=0.54). Conclusion Femoral artery intervention can be safely and effectively performed using radial, femoral, and pedal access, but radial and pedal access is associated with a lower access site complication rate and hospitalization. Pedal access is associated with a lower X-ray dose than that with radial and femoral access.

Utilization and Outcomes of Radial Artery Access for Lower Extremity Endovascular Intervention

Radial artery access has become popular for cardiac interventions, but its role in lower extremity interventions is not well defined. We aimed to describe current utilization and outcomes of transradial access for lower extremity interventions. Peripheral vascular intervention (PVI) from 2016-2020 where transradial access was employed in the Vascular Quality Initiative (VQI) registry were studied. Cases before 2016 were excluded as documentation of transradial access was not possible in earlier years. PVIs involving radial artery access were evaluated with regard to access guidance, access-site complications, target vessels treated and the technical success of these interventions. Of 167,098 PVIs, 1,096 (0.66%) involved radial access. Utilization varied significantly by region (P < 0.01). The left radial artery was used in 66.9% of cases. Ultrasound-guided access was documented in 72.7% of cases. There were no significant differences in age, body mass index, or sex between the transradial group and other PVIs. In 450 procedures, a second access site was utilized, most commonly a retrograde femoral access (60.0%) or retrograde pedal access (16.7%). The largest sheath was 6-Fr in 78.0%. Interventions documenting radial-only access more commonly treated the aortoiliac segment (49.4% vs. 29.5%, P < 0.001) and less commonly treated the tibial segments (7.1% vs. 32.1%, P < 0.001). Technical success was 94.0%, with inability to cross the lesion (3.1%) and residual stenosis after treatment (2.2%) being most common. There were access-site complications in 2.9%, with hematoma (2.4%) being most common. Radial access is associated with high technical success rates and low access-site complication rates. Advances in device profile and shaft length may overcome shortcomings of transradial access and lead to further utilization of this access site.

Closure device use for common femoral artery antegrade access is higher risk than retrograde access

Although the use of closure devices (CD) for femoral artery antegrade access (AA) is not in the instructions for use (IFU) for many devices, AA has been reported to be associated with a lower incidence of access site complications compared to manual compression alone. We hypothesized that CD use for AA would not be associated with a clinically significant increased odds of access site complications compared to CD use for retrograde access (RA). This was a retrospective review of the Vascular Quality Initiative from 2010 to 2019 for infrainguinal peripheral vascular interventions with common femoral artery access closed with a CD. Patients who had a cutdown or multiple access sites were excluded. Cases were then stratified into whether access was antegrade or retrograde. Hierarchical multivariable logistic regressions controlling for hospital level variation were used to examine the independent association between AA and access site complications. The primary outcomes were access site hematoma, stenosis, or occlusion as defined in the VQI. The secondary outcome was the development of an access site hematoma requiring an intervention, which was defined as transfusion, thrombin injection, or surgery. Sensitivity analyses after coarsened exact matching were performed to reduce residual bias. Overall, 72,463 cases were identified and 6,070 (8.4%) had AA. Patients with AA were less likely to be smokers (27.2% vs 33.0%) or obese (31.5% vs 35.6%; all P<0.05). Patients with AA were more likely to be on dialysis (12.8% vs 10.1%) and have ultrasound-guided access (76.4% vs 66.2%; P<0.05 for all). Compared to RA, patients with AA were more likely to develop any access site hematoma (2.5% vs 1.8%; P<0.01) and a hematoma requiring intervention (0.7% vs 0.5%; P=0.03), but had no difference in access site stenosis or occlusion (0.3% vs 0.2%; P=0.21). On multivariable analyses, AA had increased odds of developing any access site hematoma (OR=1.46; 95% CI=1.22-1.76) and a hematoma requiring intervention (OR=1.48; 95% CI=1.10-1.98). Sensitivity analyses after coarsened exact matching confirmed these findings. In this nationally representative sample, the use of CDs for femoral access was associated with an overall low rate of access site complications. However, there was an increased odds of access site hematomas with AA. Patient selection for AA remains important and ultrasound guided access should be the standard of care for this approach.

Safety and feasibility of transradial aortic valve valvuloplasty (TRAV study).

IntroductionThe importance of balloon aortic valvuloplasty (BAV) in the transcatheter aortic valve implantation (TAVI) era emerged in the past decades, but the access site related complication rate remained significant.AimTo establish the safety and technical success of transradial balloon aortic valvuloplasty (trBAV). The secondary objective was to determine the effectiveness and appropriate role of trBAV.Material and methodsBetween 2017 and 2019, 36 consecutive patients with symptomatic aortic stenosis (AoS) were treated with trBAV in this prospective, single-center study. During the procedure, the efficacy and the aortic valve insufficiency were controlled by hemodynamic measurements and later by echocardiography. The primary end-points were technical success and major adverse events (MAE). Secondary end-points were the access site complication rate, hemodynamic and clinical result of the intervention, procedure-related factors, crossover rate to the femoral access site and hospitalization duration.ResultsClinical and technical success was achieved in all cases. Invasively measured peak-to-peak gradient decreased from 76.8 ±27.2 to 54.7 ±21.1 mm Hg (p = 0.001), and the aortic-valve area increased from 0.69 ±0.2 to 0.91 ±0.3 cm2 (p = 0.001). No major adverse cardiac or cerebrovascular events or vascular complications (according to VARC 2 criteria) occurred during the procedures. The perioperative death rate was 2.7% (n = 1).ConclusionsAccording to our study, radial artery access is a safe and effective option for balloon aortic valvuloplasty in patients with severe aortic valve stenosis.

Abstract 16946: Radial versus Femoral Access for Coronary Procedures in Patients With Prior Coronary Artery Bypass Grafting Surgery: An Updated Study-Level Meta-Analysis

Introduction: The preferred access site for cardiac catheterization in patients with prior coronary artery bypass surgery (CABG) continues to be debated. Methods: We performed a systematic review and meta-analysis of two randomized trials and eighteen observational studies, including 58,237 patients with prior CABG (27,063 in the radial group; 31,174 in the femoral group) that underwent cardiac catheterization with or without intervention. Outcomes included (1) access-site complications rate; (2) crossover rate to a different vascular access; (3) procedure time; and (4) contrast volume. Data were extracted by two independent authors; using a random effects model, standardized mean differences (SMD) and 95% confidence interval (CI) were calculated for continuous outcomes, whereas odds ratio (OR) and 95% CI were calculated for binary outcomes. Results: Among randomized trials, the crossover rate (OR:12.63; 95% CI: 1.57,101.62; p=0.021) was higher in the radial group, while contrast volume (SMD: 0.15; 95% CI: -0.52, 0.82, p=0.66), procedure time (SMD: 0.49; 95% CI: -0.64, 1.62, p=0.4) and the incidence of access site complications (OR:1.21; 95% CI: 0.36, 4.07; p=0.76) and were similar. Among observational studies, access site complication rates (OR:0.46; 95% CI: 0.25,0.86; p&amp;lt;0.001) and contrast volume (SMD: -0.14; 95% CI: -0.20, -0.07; p=0.03) were lower and crossover rates were higher (OR: 4.79; 95% CI: 1.99, 11.52, p=0.02) in the radial group, while procedure time was similar (SMD: 0.13; 95% CI: -0.08, 0.34, p=0.02). Conclusions: Most data published for radial vs. femoral access in prior CABG patients are observational with only two randomized-controlled trials performed to date. Radial access is associated with lower vascular access complication rates and contrast volume in observational studies and higher rates of crossover to femoral access in both observational and randomized studies.

Transradial access for embolization of cerebral aneurysms with the woven EndoBridge device: Case series and review of the literature.

Transradial access is an increasingly utilized route for neurointerventions with benefits of lower rates of access site complications, earlier patient mobilization and increased patient satisfaction over transfemoral interventions. There is limited data on deployment of the Woven EndoBridge (WEB) via transradial access. We report a case series of consecutive patients undergoing cerebral aneurysm embolization with the WEB device via transradial biaxial access. A database of neuroendovascular procedures was queried for consecutive aneurysm embolization procedures involving the WEB device and intended via the transradial approach between August 2019 and July 2020. Patient demographics, radiological aneurysm characteristics and procedure details were recorded and statistically evaluated. Google Scholar and Pubmed were searched for previous reports of transradial WEB embolization. Ten aneurysms were treated in ten patients. All aneurysms were treated with successful WEB deployment. Nine of the ten aneurysms were successfully treated via transradial biaxial access. One aneurysm required conversion to transfemoral access. There were no clinical complications and no morbidity or mortality. Transradial embolization of cerebral aneurysms with the WEB device is safe and feasible with low rates of access failure or complications.

TRIACCESS study: randomized comparison between radial, femoral and transpedal access for for percutanous supertfitial femoral artery angioplasty

Abstract Background Traditional access for the treatment of femoral artery lesions is the femoral artery (FA) approach, but radial (RA) and pedal access (PA) is an alternative access site. The aim of the study was to compare the success rate, complication rate of different access sites for the treatment of superfitial artery stenosis in a randomized study Methods 180 consecutive patients were randomized in a prospective study to treat symptomatic superficial femoral stenosis, via RA, FA and PA. Primary endpoint: technical success, rate of major and minor access site complications. Secondary endpoints: major adverse events (MAE), procedural factors, cross-over rate, and duration of hospitalization. Results Technical success was achieved in 96.6%, 100% and 100% patients in RA, FA and PA group (p=ns). Secondary access site was used in 30%, 3.3% and 30% in the RA, FA and PA access group (p&amp;lt;0.01). Stent implantation was done in the femoral artery in 26.6%, 58.3% and 71.6% cases in RA, FA and PA group (p&amp;lt;0.01). CTO recanalization was performed in 34/36 (100%), 30/30 (100%) and 45/45 (100%) cases successfully in RA, FA and PA group (p=ns). Contrast consumption, fluoroscopy and procedure time was not statistically different, but the X Ray dose was significantly lower in PA than in the RA and FA access group (63.1 vs 162 vs 153 Dyn). The cumulative rate of access site complications in the RA, FA and PA group was 3.3% (0% major and 3.3% minor), 15% (3.3% major and 11.6% minor) and 3.3% (0% major and 3.3% minor) (p&amp;lt;0.01), respectively. The cumulative incidence of MAE's at 6 months in the RA, FA and PA group was 8.3% vs 13.3% and 18.3%. (p&amp;lt;0.05) Conclusion Femoral artery intervention can be safely and effectively performed using radial, femoral and pedal access, but radial and pedal access is associated with less access site complication rate. Pedal access is associated with less X Ray dose than radial and femoral access. Funding Acknowledgement Type of funding source: None
