Background: Transradial access (TRA) is not a common vascular access in children. We have been performing TRA actively to reduce puncture complications, and the purpose of this study was to investigate the safety and efficacy of TRA in young children.

Methods: The study included 29 patients aged 5-12 years who underwent diagnostic catheterization at Kurume University Hospital.

Transcatheter Aortic Valve Replacement: Full Unilateral Access Using the Ipsilateral Superficial Femoral Artery Is Effective.

Background: Access site complications are very common complications in transcatheter aortic valve replacement (TAVR). Usually, a second arterial sheath is placed either in the contralateral femoral artery or in the radial artery as a simplified approach. This study aimed to investigate the safety and effectiveness of a full unilateral access using the ipsilateral superficial femoral artery (iSFA) in TAVR and to determine whether it simplifies the procedure.

Impact of X-Ray Protective Drapes on Operator and Patient Radiation Exposure During Cardiac Catheterization.

Background: As cardiac catheterization operators are exposed to radiation exposure throughout their careers, optimal radiation protection is crucial. Our study was designed to assess the effects of supplementary protective measures beyond standard radiation protection attire and barriers, measuring their influence on scatter radiation exposure levels for both the operator and the patient.

Aims: The objective of this trial is to assess the impact of a lead shield on scatter radiation exposure for both the operator and the patient.

Early identification of vascular access site complications and frequent heart rate and blood pressure monitoring after cardiac catheterization: A scoping review.

Background: Nurses perform frequent heart rate (HR) and blood pressure (BP) monitoring, a widespread and longstanding practice, after cardiac catheterization (CC) to identify vascular access site complications for femoral and radial arterial approach in adult patients.

Objective: The objective of this scoping review was to answer two questions: (1) how does the available evidence support frequent HR and BP monitoring after CC via femoral and radial approach in adult patients and (2) how does this practice prompt bedside nurses in identifying the procedure's major vascular access site complications, including bleeding, hematoma, and pseudoanurysm?

Method: Following the scoping review approach, literature search was conducted (PubMed, CINAHL, Google Scholar) by two co-authors and medical librarian. We reviewed, evaluated, and analyzed the evidence from twenty articles.

Distal radial artery palpability and successful arterial access for coronary angiography: A post-hoc analysis from two randomized trials.

Background: Distal radial artery access (DRA) has been emerged as an alternative for conventional transradial arterial access. While palpation of radial artery is mandatory prior coronary angiography, it remains unknown the clinical impact of palpation in DRA success. Aim of our study is to explore whether the palpability of distal radial artery is linked with higher rates of successful arterial access.

Ultrasound-guided thrombin injection for cardiac catheterization pseudoaneurysms: efficacy, safety, and predictors.

Background: Percutaneous ultrasound-guided thrombin injection has become the gold standard treatment for pseudoaneurysms caused by cardiac catheterization. However, failure can occur in up to 25% of the procedures and little is known about its causes.

Purpose: To study the efficacy and safety of the technique and to determine possible risk factors responsible for the unsuccess.

Comparing arterial catheterisation by palpation or ultrasound guidance by novice nurses in an adult intensive care unit: A prospective cohort study.

Background: Arterial catheterisation is a common procedure in intensive care units (ICUs), typically performed using the palpation technique. Ultrasound (US)-guided catheterisation remains underutilised, particularly when performed by nonphysician operators.

Objective: The objective of this study was to assess the effectiveness of US-guided arterial catheterisation performed by nurses in critically ill patients.

Right mini-thoracotomy for concomitant aortic valve replacement and right coronary artery bypass graft.

Background: Full sternotomy is the standard approach for combined surgery. Evidence of the minimally invasive approach's advantages for aortic and mitral valve surgery has been reported. Our aim was to report our experience with minithoracotomy for elective patients presenting with aortic valve stenosis associated with right coronary artery disease.

Risk factors for puncture-related complications after cerebrovascular angiography and neuroendovascular intervention with distal transradial approach.

Background And Purpose: To determine the risk factors for puncture-related complications after the distal transradial approach (dTRA) for cerebrovascular angiography and neuroendovascular intervention and to explore the incidence and potential mechanisms of procedural failure and puncture-related complications.

Materials And Methods: From February to November 2023, 62 patients underwent dTRA in our department. Demographic, clinical, and procedural data were collected retrospectively.

Intravascular Ultrasound Assessment of Distal Trans-Radial Access in Patients Undergoing Percutaneous Coronary Intervention.

Background: Distal trans-radial access (dTRA) for percutaneous coronary interventions (PCI) is increasingly gaining attention due to its potential to mitigate radial artery occlusion (RAO). However, a comprehensive understanding of the mechanical impact of the devices on the radial artery (RA) wall remains limited. Using a complete intravascular ultrasound (IVUS) evaluation of the RA, including also the vascular access site, we aimed to evaluate all the consequences related to the catheterization on the RA wall, starting from the vascular access, comparing conventional sheath and sheathless approaches.

Recurrent Acute Upper Limb Ischemia in a Young Male: Case Report.

Although acute upper limb ischemia (AULI) is less prevalent than lower acute limb ischemia, AULI may lead to severe morbidity if not well-treated. To manage AULI appropriately, evaluation of the etiologies, risk factors, and revascularization is of importance. Here we present a case of recurrent AULI and its appropriate diagnostic and management approaches.

Does the resistive index of the radial artery change after arterial cannulation in patients undergoing abdominal surgery? A prospective observational study.

Background And Aims: To evaluate the flow at the cannulation site in the radial artery, the resistive indices (RIs) before cannula insertion and 6 h after decannulation were measured (primary outcome). The secondary outcomes were measurement of the artery size by anteroposterior (AP) diameter at the insertion site, RI and AP diameter at a point 4 cm proximal and in the ipsilateral ulnar artery before insertion and 6 h after cannula removal.

Methods: In 96 patients requiring an arterial line during surgery, peak systolic velocity (PSV) and end-diastolic velocity (EDV) were measured to derive RI using a linear ultrasound transducer.
