Radial versus femoral

BACKGROUND: During transcatheter aortic valve implantation (TAVI), secondary access is required for angiographic guidance and temporary pacing. The most commonly used secondary access sites are the femoral artery (angiographic guidance) and the femoral vein (temporary pacing). An upper extremity approach using the radial artery and an upper arm vein instead of the lower extremity approach using the femoral artery and femoral vein may reduce clinically relevant secondary access site-related bleeding complications, but robust evidence is lacking...

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...

BACKGROUND: The Woven EndoBridge (WEB) device is a minimally invasive endovascular treatment option for patients with cerebral aneurysms. Transradial access (TRA) is a technique that involves accessing the arterial system through the radial artery in the wrist rather than the femoral artery in the groin. Several studies have investigated the use of TRA for WEB device deployment in treating intracranial aneurysms. METHODS: A systematic review was conducted to evaluate the TRA for WEB device deployment in treating intracranial aneurysms...

BACKGROUND: Femoral version deformities have recently been identified as a major contributor to femoroacetabular impingement (FAI). An in-depth understanding of the specific labral damage patterns caused by femoral version deformities may help to understand the underlying pathomorphologies in symptomatic patients and select the appropriate surgical treatment. QUESTIONS/PURPOSES: We asked: (1) Is there a correlation between femoral version and the mean cross-sectional area of the acetabular labrum? (2) Is there a difference in the location of lesions of the acetabular labrum between hips with increased femoral version and hips with decreased femoral version? (3) Is there a difference in the pattern of lesions of the acetabular labrum between hips with increased femoral version and hips with decreased femoral version? METHODS: This was a retrospective, comparative study...

BACKGROUND AND OBJECTIVES: Femoral access (TFA) for neuroendovascular procedures may present a challenge in very high body mass index (BMI) individuals. Whether Radial access (TRA) confers a comparative benefit in this specific population has not been studied. METHODS: We retrospectively identified all patients undergoing neuroendovascular procedures at our center between 2017-2021 with BMI ≥ 35 kg/m2 . 335 patients met our inclusion criteria, with 224 undergoing femoral access and 111 undergoing radial access...

BACKGROUND: Outpatient diagnostic cerebral arteriograms are the most common procedure in neuroendovascular surgery, and the use of transradial access for these studies is growing. Although transradial access has been associated with lower hospital costs for elective diagnostic and interventional neuroendovascular procedures, no study has compared transfemoral access and transradial access costs for a homogenous population of patients undergoing outpatient diagnostic cerebral arteriogram...

INTRODUCTION: Both the trans-radial approach (TRA) and the trans-femoral approach (TFA) have been employed for cerebral angiography, but the relative advantages of these two techniques remain uncertain. AIM: To compare the relative safety and efficacy of the TRA and TFA when conducting cerebral angiography. MATERIAL AND METHODS: Relevant studies published up to August 2022 were identified in the PubMed, Embase, and Wanfang databases. The rate of successful cerebral angiography was the primary study endpoint, while secondary endpoints included successful puncture rates, operative duration, puncture time, fluoroscopic duration, complication rates, and duration of postoperative recovery...

BACKGROUND: The carotid artery stenting (CAS) has two common access sites: transradial access (TRA) and transfemoral access (TFA). However, there's no definitive answer to which one is superior. OBJECTIVE: Compare TRA and TFA for the CAS. METHODS: A systematic review of the literature of studies reporting both TRA and TFA results was conducted following the PRISMA guidelines. PubMed, Cochrane Library, Web of Science and Embase were queried...

BACKGROUND: Many studies have demonstrated the benefit of complete multivessel revascularization versus culprit-only intervention in patients of ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease. However, only a few single-center retrospective studies were performed on small Chinese cohorts. Our study aims to demonstrate the advantage of multivessel percutaneous intervention (PCI) strategy on 30-day in-hospital outcomes to patients with STEMI and multivessel disease in larger Chinese population...

Endovenous laser ablation (EVLA) is a common minimally invasive technique used to treat varicose veins. The most commonly used laser wavelengths for EVLA/EVLT of varicose veins are 810 nm and 1470 nm. The laser pulse frequency is typically set to continuous wave (CW) mode, with a pulse duration of a few milliseconds (ms) delivered in a radial mode. The energy delivered per pulse is typically set between 40 and 120 Joules, with a power setting of 10 to 30 watts and an intensity setting of 40 to 120 J/cm2 . The controversy exists regarding the benefits of performing saphenofemoral junction (SFJ) ligation prior to EVLA to decrease the recurrence rate of varicose veins...

Background and aims The trans-radial access is becoming the default approach in many cardiac centers worldwide. Data from the Middle East, including Iraq, on the trends and rates of the use of trans-radial access are scarce. The aim of this study is to determine the rates of trans-radial approach (TRA) versus transfemoral approach (TFA) in patients with coronary artery syndromes undergoing coronary angiography and/or percutaneous coronary intervention (PCI) in Iraq. Methods In this multicenter prospective study, we collected 885 cases of coronary artery disease undergoing coronary angiography/PCI from three main cities of the Kurdistan Region in Iraq from 2022 to 2023...

AIM: Peri-cardiac catheterization (CC) stroke is associated with increased morbidity and mortality. Little is known about any potential difference in stroke risk between transradial (TR) and transfemoral (TF) approaches. We explored this question through a systematic review and meta-analysis. METHODS: MEDLINE, EMBASE, and PubMed were searched from 1980 to June 2022. Randomized trials and observational studies comparing radial versus femoral access CC or intervention that reported stroke events were included...

OBJECTIVE: The aortic-to-radial arterial pressure gradient is described during and after cardiopulmonary bypass (CPB), and can lead to underestimating arterial blood pressure. The authors hypothesized that central arterial pressure monitoring would be associated with lower norepinephrine requirements than radial arterial pressure monitoring during cardiac surgery. DESIGN: An observational prospective cohort with propensity score analysis. SETTING: At a tertiary academic hospital's operating room and intensive care unit (ICU)...

Hispanic individuals are underrepresented in skeletal research. Bone mineral density (BMD) and fracture data are conflicting. We investigated skeletal health in elderly Caribbean Hispanic (HW), non-Hispanic white (NHW), and non-Hispanic black (NHB) women in a population-based study in New York City. We utilized high-resolution peripheral quantitative CT (HRpQCT), dual-energy X-ray absorptiometry (DXA), and finite element analysis (FEA). Of 442, 48.4% were HW, 21.3% NHW, and 30.3% NHB. Adjusted analyses are shown...

Background: Endovascular thrombectomy (EVT) through femoral access is difficult to perform in some patients with acute ischemic stroke due to challenging vasculature. We compared outcomes of EVT through femoral versus alternative arterial access. Methods: In this observational study, we included patients from the MR CLEAN Registry who underwent EVT for acute ischemic stroke in the anterior circulation between 2014 and 2019 in the Netherlands. Patients who underwent EVT through alternative and femoral access were matched on propensity scores in a 1:3 ratio...

BACKGROUND: Vascular injury and bleeding complications remain frequent after transcatheter aortic valve replacement (TAVR). Whether the access-site of preprocedural coronary angiography (CAG) affects TAVR-related complications is not known. The aim of this study was to evaluate the impact of transradial (TRA) versus transfemoral access (TFA) for preprocedural CAG on outcomes in patients undergoing subsequent TAVR. METHODS: The study cohort included 1002 patients undergoing transfemoral TAVR, of whom 39...

Carotid artery stenting (CAS) is usually performed through a femoral vascular access using 6-9 Fr guiding catheters. We investigated whether a systematic distal radial approach using 5 Fr guiding sheaths was a safe and effective alternative to transfemoral approach for CAS. From July 2020 to October 2022, two operators at our center systematically performed CAS using a 5 Fr distal radial approach in consecutive patients. The main endpoints of the study were procedural success via distal radial and via proximal or distal radial access...

INTRODUCTION: The detrimental effects of radiation exposure to physicians have been well documented and are an active area of concern. The objective of this study was to evaluate the radiation protection offered by an exoskeleton-based radiation protection system (StemRad MD, StemRad Ltd, Israel). METHODS: The experimental setup involved two anthropomorphic phantoms, an operator and a patient, and a C-arm as the X-ray radiation source. Thermo-luminescent detectors were used to measure radiation doses to different radiosensitive body parts on the operator phantom both with the StemRad MD and conventional lead apron (LA), at the left radial and right femoral positions...
