The distal radial artery: Versatile vascular access for transcatheter interventions

Conventional transradial access has been established as the gold standard for invasive coronary angiography and percutaneous interventions by the current European and American guidelines. The distal or snuffbox radial artery access represents an alternative transradial access site that allows radial sheath insertion with the patient’s hand pronated. Firstly described 40 years ago, it exploded in popularity only recently. Promising additional benefits, the distal radial access is increasingly being adopted in various types of percutaneous interventions, being preferred by many interventional cardiologists and radiologists for its reduced vascular complications and time to hemostasis, and improvement of patient and operator comfort. Other centers consider it a fad, waiting for solid clear evidence and benefits. The evidence is dynamic and discrepant, depending on the center, the operator, and how it was collected (randomized controlled vs observational studies). Another essential aspect raised by “skeptics” was whether distal radial access, by its smaller diameter and more angled course, can support all types of interventions. The aim of this review is to gather all the scenarios where distal radial access has been utilized and to conclude whether this vascular access is feasible across all transcatheter interventions

A case report of COVID-19-associated acute hand ischaemia in a young professional volleyball player

Several coronavirus disease-19 (COVID-19)-associated complications are being increasingly reported, including arterial and venous thrombo-embolic events that may lead to amputation of the affected limbs. So far, acute upper limb ischaemia (ULI) has been reported only in critically ill patients.Herein, we aimed to present a case of a 29-year-old, otherwise healthy male volleyball player, with acute ischaemic signs in the upper extremity who was diagnosed with COVID-19 1 month before the ischaemic event. It has been shown that volleyball players experience repetitive stress that involves their hands and, in particular, their fingers. Repetitive trauma can lead to local vascular abnormalities, such as reduced capillarization and lower resting blood flow that can lead to pain and cold digits, but never acute ULI.To our knowledge, this is the first case of such a hypercoagulable synergistic mechanism that leads to a high thrombus burden. Intra-arterial local thrombolysis and percutaneous transluminal angioplasty failed to succeed, and percutaneous large-bore embolectomy with the Indigo Aspiration System (Penumbra Inc., CA, USA) was deemed necessary

Surgical Turned-Downed CHIP Cases—Can PCI Save the Day?

Current guidelines, rarely if at all, address decision-making for revascularization when bypass surgery is not a possibility for high-risk cases. Patients who are surgically turned down are routinely excluded from clinical trials, even though they remain symptomatic. Furthermore, the reasons for surgical ineligibility are often times not captured in standardized risk models. There is no data regarding health status outcomes following PCI procedures in these patients and the ultimate question remains whether the benefits of PCI outweigh its risks in this controversial subpopulation. When CHIP (Complex High risk Indicated Percutaneous coronary interventions) is selected for these very complex individuals, there is no unanimity regarding the goals for interventional revascularization (for instance, the ambition to achieve completeness of revascularization vs. more targeted or selective PCI). The recognition that, worldwide, these patients are becoming increasingly prevalent and increasingly commonplace in the cardiac catheterization labs, along with the momentum for more complex interventional procedures and expanding skillsets, gives us a timely opportunity to better examine the outcomes for these patients and inform clinical decision-making

Simultaneous Dual Distal Radial Balloon Aortic Valvuloplasty for Larger Aortic Annuli

Dual distal mini-balloon aortic valvuloplasty stabilized an 85-year-old patient with severe aortic stenosis. Puncturing both radial arteries solves the issue of large diameters at the aortic ring, introducing a feasible strategy in selected cases of fragile octogenarian patients with a high hemorrhagic risk. Moving at the anatomical snuffbox offers better postprocedural occlusion rates and better workspace ergonomics during the procedure

Superficial temporal artery access for carotid artery stenting: A case report

Percutaneous intervention of patients who suffer from generalized vascular disease is often a great challenge due to the limited accessibility of the access gates. We discuss the case of a 66-year-old man who presented with critical right internal carotid artery (ICA) stenosis after previous hospitalization due to stroke. In addition to arteria lusoria, the patient had known bilateral femoral amputation, occlusion of the left ICA and significant three-vessel coronary artery disease. After unsuccessful common carotid artery (CCA) cannulation from the right distal radial artery access, we successfully performed the diagnostic angiography and the planned right ICA-CCA intervention using superficial temporal artery (STA) puncture. We showed that STA access can be used as an alternative and additional access site for diagnostic carotid artery angiography and intervention when standard access sites alone are insufficient

Distal Radial Artery Access for Recanalization of Radial Artery Occlusion and Repeat Intervention: A Single Center Experience

Background: Once occluded, the radial artery becomes unsuitable for repeat interventions and obligates the need for alternative vascular access, such as the femoral approach, which is not encouraged by current guidelines. With the dissemination of distal radial access (DRA), which allows the cannulation of the artery in its distal segment and which remains patent even in the case of radial artery occlusion (RAO), the option to perform angioplasty at this level becomes feasible. Methods: Thirty patients with RAO were enrolled in this pilot study. Recanalization was performed through DRA using hydrophilic guidewires. The feasibility endpoint was procedural success, namely the successful RAO recanalization, the efficacy endpoint was patency of the artery at 30 days, and the safety endpoint was the absence of periprocedural vascular major complications or major adverse cardiac and cerebrovascular events. Results: The mean age of the patients was 63 ± 11 years, and 15 patients (50%) were men. Most patients had asymptomatic RAO (n = 28, 93.3%), and only two (6.6%) reported numbness in their hands. The most common indication for the procedure was PCI (19, 63.2%). Total procedural time was 41 ± 22 min, while the amount of contrast used was 140 ± 28 mL. Procedural success was 100% (n = 30). Moreover, there were no major vascular complications (0%); only two small hematomas were described (10%) and one had an angiographically visible perforation (3%). One case of periprocedural stroke was reported (3%), with onset immediately after the procedure and recovering 24 h later. Twenty-seven radial arteries (90%) remained patent at the one-month follow-up. Conclusions: RAO recanalization is feasible and safe, and by using dedicated hydrophilic guidewires, the success rate is high without significantly increasing procedural time or the amount of used contrast
