Transradial angiography

BACKGROUND: Coiling of small superior cerebellar artery (SCA) aneurysms (sSCAAs) is challenging. We aimed to describe anatomical considerations in the vertebral and basilar artery (VA and BA) morphology for decision-making in coiling of sSCAAs. METHODS: 11 patients with sSCAAs (<5mm) treated at our institution between April 2015 and Februrary 2022 were included to show our concept of deciding access routes in coiling of sSCAAs. The access route was decided based on VA characteristics, BA curvature, and aneurysm laterality...

The introduction of transradial access for percutaneous coronary diagnostic and interventional procedures has led to a decrease in access site complications. The aim of this paper is to propose a combined stepwise technical approach where real time ultrasound ("echo-first" approach) can be used to select the best vascular access and, together with angiography, to manage the potential obstacles that may occur during transradial procedures. In each section, we summarize some tips and tricks based on both our experience and current literature that can be easily implemented in daily practice to increase the success of transradial procedures...

Successful percutaneous coronary intervention (PCI) to anomalous coronary arteries is technically challenging, particularly through transradial route. The application of appropriate techniques and devices may help overcome these challenges. The objective of this study is to explore the technical and procedural challenges in percutaneous coronary intervention (PCI) of anomalous origin of right coronary artery (AORCA) through the trans-radial route. This prospective study consisted of 25 consecutive patients who underwent PCI for an angiographically significant stenosis in AORCA from November 2017 to May 2019 at Ibrahim Cardiac Hospital & Research Institute (ICHRI)...

BACKGROUND: Transradial coronary angiography can be performed using a dual-catheter technique (DCT) or single-catheter technique (SCT). The current study aimed to compare DxTerity SCT Ultra and the Trapease curve SCT catheters with DCT catheters in procedures performed by young, less experienced, interventional cardiologists. METHODS: For this prospective, single-blinded, randomized study 107 were enrolled and assigned to 1 of 3 groups. They underwent planned coronary angiography at the Second Department of Cardiology Jagiellonian University in Kraków...

The distal transradial approach (dTRA) through the anatomical snuffbox is hypothesized to offer greater benefits than the conventional transradial access (cTRA) for patients undergoing coronary procedures. Our goal was to assess the safety and efficacy of dTRA. Out of 465 consecutive Caucasian patients, 400 were randomized (1:1) to dTRA or cTRA in a prospective single-center trial. Clinical and ultrasound follow-ups were obtained at 24 h and 60 days post-procedure. The primary combined endpoint consisted of access crossover, access-related complications, and major adverse cardiovascular events (MACE)...

Transvenous access is a necessary tool for numerous cerebrovascular pathologies.Transvenous access in the arm offers several benefits compared with transfemoral access, including patient comfort, the avoidance of transfemoral access complications, and the ability to close both radial arterial access and distal arm venous access with a single transradial compression band.1In this video we describe the indications, technical nuances, benefits, and limitations of transvenous access in the arm.neurintsurg;jnis-2023-020996v1/V1F1V1Video 1- Combined venous and arterial access in the arm for treatment of a complex dural arteriovenous fistulaWe present the case of a young patient who presented with pulsatile tinnitus and was found to have a Cognard type IIa dural arteriovenous fistula near the left transverse sigmoid junction...

OBJECTIVES: Previous studies show that the distal transradial approach (dTRA) is safe and effective for coronary angiography and percutaneous coronary intervention. However, the effect of dTRA on radiation exposure in the catheterization laboratory has not been characterized. The authors analyzed the available literature to compare the radiation exposure associated with dTRA vs the traditional radial approach (TRA). METHODS: A systematic review and meta-analysis of the scientific literature was conducted by using relevant terms to search the PubMed, Embase, and Cochrane Library databases from their inception until October 13, 2022, to identify randomized controlled trials (RCTs) comparing dTRA with TRA...

BACKGROUND: Older patients are at a higher risk of access site complications and bleeding. Systematic reviews and meta-analysis have highlighted the benefits of distal over proximal transradial access (mainly, lower rates of radial artery occlusion and faster hemostasis). We aimed to evaluate the feasibility and safety of distal transradial access (dTRA) for routine coronary procedures in older patients compared with non-older patients. METHODS: Retrospective analysis of a large and real-world sample of 5524 consecutive all-comers patients who underwent coronary procedures via dTRA were included in the DISTRACTION registry...

OBJECTIVE: Recently, the transradial (TR) approach has become a common alternative because of its safety profile and increased patient satisfaction compared with the transfemoral (TF) route. Both routes are associated with their respective associated costs, and differences typically emerge on the basis of patient anatomy, operator expertise, and occurrence of complications. The authors' objective was to compare the overall costs of diagnostic cerebral angiography via both routes and to shed light on the individual equipment costs of each route...

OBJECTIVES: Guidewire occasionally creates a loop-like appearance between the right subclavian artery and brachiocephalic artery when performing coronary angiography (CAG) with right radial artery (RtRA) access. We called this occurrence a looped guidewire at the brachiocephalic artery (looped GW at BA). It is associated with difficulties in catheter manipulation. This study aimed to assess the predictors of forming a looped GW at the BA. METHODS: We examined 175 (mean age, 71...

Background Acute coronary syndrome (ACS) is the leading cause of morbidity and mortality worldwide. The different reperfusion strategies have evolved over the years, and efforts have been directed to reduce its complications. Among these strategies, the one that has shown the best results is percutaneous coronary intervention, which has significantly improved the survival and prognosis of these patients; however, this procedure is not free of complications since multiple factors are involved. Among them is the time of patient care from the time of diagnosis until the coronary reperfusion therapy is performed...

BACKGROUND: Distal transradial artery access (dTRA) has received increasing consideration for performing diagnostic cerebral angiography and neurointerventional procedures. In this meta-analysis, we aim to evaluate the safety and efficacy of dTRA compared to conventional transradial access (cTRA) for cerebral angiography and neurointerventions. METHOD: A systematic review and meta-analysis were conducted on studies investigating outcomes of dTRA and cTRA in neurointerventions...

Basic patient characteristics, angiographic data, postoperative complications, and patient satisfaction were collected for analysis...

BACKGROUND: Historically, the transfemoral approach (TFA) has been the most common access site for cerebral intraoperative angiography (IOA). However, in line with trends in cardiac interventional vascular access preferences, the transradial approach (TRA) and transulnar approach (TUA) have been gaining popularity owing to favorable safety and patient satisfaction outcomes. OBJECTIVE: To compare the efficacy and safety of TRA/TUA and TFA for cerebral and spinal IOA at an institutional level over a 6-year period...

BACKGROUND: Transradial access is an important tool for many neuroendovascular procedures. Occlusion of the radial or ulnar artery is not uncommon after transradial or transulnar access, and can present a challenge for patients requiring repeat angiography. METHODS: Between March 2022 and June 2023, patients undergoing a transradial or transulnar angiogram who were found to have a radial artery occlusion (RAO) or ulnar artery occlusion were identified. Repeat catheterization of the occluded artery was attempted using a 21-gauge single wall puncture needle and a 0...
