Simplified transradial access for aneurysms treatment: A guiding system using solo distal access catheter and anatomical considerations

The recent shift from transfemoral access to transradial access in neurointervention has led to gaps in guiding systems. We propose a useful guiding system, the solo distal access catheter system without a conventional guiding catheter or a sheath in transradial access for aneurysms treatment. We also assessed the anatomical features required for suitable patient selection.

A Comparison of Outcomes Between Transfemoral Versus Transradial Access for Carotid Stenting

The transradial (TR) approach has emerged as an alternative to the transfemoral (TF) approach in carotid artery stenting (CAS) because of its perceived benefits in access site complications and overall patient experience.

Feasibility and safety of transradial intraoperative angiography for neurosurgery: An institutional experience

Transradial approach for neuroangiography is becoming increasingly popular because of the advantages demonstrated by interventional cardiology. Many advantages of radial access could be applied to intraoperative angiography.

Therapeutic efficacy and complications of radial versus femoral access in endovascular treatment of unruptured intracranial aneurysms

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.

Transradial versus transfemoral access in carotid artery stenting: A meta-analysis

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.

Comparing Outcomes of Transfemoral Versus Transbrachial or Transradial Approach in Carotid Artery Stenting (CAS)

While Transfemoral Carotid Artery Stenting (TFCAS) is a valid minimally invasive option for patients who also might be suitable for carotid endarterectomy (CEA) or transcarotid artery revascularization (TCAR), alternative access sites such as transbrachial (TB) or transradial (TR) are only utilized when anatomic factors preclude direct carotid or transfemoral access. In this study, we aimed to evaluate the outcomes of TR/TB access in comparison to TF for percutaneous carotid artery revascularization.

Comparing the Safety and Feasibility of Endovascular Therapy via Transradial and Transfemoral Approaches in Patients with Aortoiliac Occlusive Disease: A Propensity Score-Matched Analysis of the Nationwide Registry

Our objective was to evaluate the feasibility of performing endovascular therapy (EVT) for aortoiliac artery disease using transradial approach (TRA) as compared to transfemoral approach (TFA).

Left Transradial Access Using a Radial-Specific Neurointerventional Guiding Sheath for Coil Embolization of Anterior Circulation Aneurysm Associated With the Aberrant Right Subclavian Artery: Technical Note and Literature Review

Aberrant right subclavian artery (ARSA) is a rare condition, but the most common anomaly of the aortic arch. Although neurointerventions via transradial access (TRA) are becoming increasingly popular worldwide, transradial carotid cannulation has been extremely challenging in patients with an ARSA. Herein, we present a case of ARSA-associated anterior communicating artery (ACoA) aneurysm that was successfully treated with a radial-specific 6F Simmons guiding sheath via left TRA. We also review the relevant literature.

Predicting difficult transradial approach guiding into left internal carotid artery on unruptured intracranial aneurysms

The transradial approach (TRA) is less invasive than the transfemoral approach (TFA), but the higher conversion rate represents a drawback. Among target vessels, the left internal carotid artery (ICA) is particularly difficult to deliver the guiding catheter to through TRA. The purpose of this study was thus to explore anatomical and clinical features objectively predictive of the difficulty of delivering a guiding catheter into the left ICA via TRA.

Radial access for peripheral vascular intervention: the S.M.A.R.T. RADIANZ Vascular Stent System

Radial access is the standard of care for nearly all cardiac catheterization procedures. It improves patient satisfaction, reduces the length of stay, and is associated with fewer complications. However, few devices and tools are available for the treatment of peripheral arterial disease via a transradial approach (TRA). The S.M.A.R.T. RADIANZ Vascular Stent System is among the RADIANZ suite of products, which is aimed at expanding the portfolio of devices to treat peripheral arterial disease.
