Distal versus proximal radial artery access for cardiac catheterization and intervention: Design and rationale of the DIPRA trial.

Cardiovasc Revasc Med 2021 Apr 15. Epub 2021 Apr 15.

Interventional Cardiology and Structural Heart Disease, The Heart Hospital - Plano, Baylor Scott & White Health, United States of America.

Background: Radial artery (RA) catheterization is the access of choice over femoral artery access for most interventional vascular procedures given its safety and faster patient recovery. There has been growing interest in distal radial artery (dRA) access as an alternative to the conventional proximal radial artery (pRA) access. Preserving the RA is important which serves as a potential conduit for future coronary artery bypass surgery, dialysis conduit or preserve the artery for future cardiovascular procedures. Read More

Margin of safety for needle puncture of a radial artery.

J Anesth 2021 Apr 12. Epub 2021 Apr 12.

Department of Anesthesiology, Dokkyo Medical University Saitama Medical Center, 2-1-50 Minami-Koshigaya, Koshigaya, Saitama, 343-8555, Japan.

The radial artery is the preferred site for arterial cannulation because of consistent anatomic accessibility, ease of cannulation, and a low incidence of complications. One possible risk associated with cannulation is an injury to the superficial branch of the radial nerve. The radial nerve divides to the superficial branch and the deep branch at the top of the forearm, and the superficial branch lies behind the brachioradialis muscle close to the lateral side of the radial artery and terminates the lateral side of the radial artery about 7 cm proximal to the wrist.

JACC Cardiovasc Interv 2021 Apr 31;14(8):907-916. Epub 2021 Mar 31.

Duke Clinical Research Institute, Durham, North Carolina, USA. Electronic address:

Objectives: The aims of this study were to examine rates of radial artery access in post-coronary artery bypass grafting (CABG) patients undergoing diagnostic catherization and/or percutaneous coronary intervention (PCI), whether operators with higher procedural volumes and higher percentage radial use were more likely to perform diagnostic catherization and/or PCI via the radial approach in post-CABG patients, and clinical and procedural outcomes in post-CABG patients who undergo diagnostic catherization and/or PCI via the radial or femoral approach.

Background: There are limited data comparing outcomes of patients with prior CABG undergoing transradial or transfemoral diagnostic catheterization and/or PCI.

Methods: Using the National Cardiovascular Data Registry CathPCI Registry, all diagnostic catheterizations and PCIs performed in patients with prior CABG from July 1, 2009, to March 31, 2018 (n = 1,279,058, 1,173 sites) were evaluated. Read More

Early radial artery occlusion following the use of a transradial 7-French sheath for complex coronary interventions in Chinese patients.

Catheter Cardiovasc Interv 2021 May 22;97 Suppl 2:1063-1071. Epub 2021 Mar 22.

Coronary Heart Disease Center, Department of Cardiology, Fuwai Hospital, State Key Laboratory of Cardiovascular Disease, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Objectives: We aimed to explore the impact of 7-Fr sheaths on the incidence of early radial artery occlusion (RAO) after transradial coronary intervention (TRI) in Chinese patients.

Background: RAO precludes future use of the vessel for vascular access. Transradial catheterization is usually performed via 5-Fr or 6-Fr catheters; 7-Fr sheath insertion enables complex coronary interventions but may increase the RAO risk. Read More

Safety of arterial catheterization using the distal radial approach in intensive care unit management: A pilot study.

J Vasc Access 2021 Mar 21:11297298211003374. Epub 2021 Mar 21.

Department of Emergency and Critical Care Medicine, Kitasato University School of Medicine, Sagamihara, Kanagawa, Japan.

Background: Arterial catheter (A-line) is essential for managing severely ill patients, and the radial artery is the most common insertion site in the intensive care unit (ICU). However, many accidental removals occur because the insertion site of A-line in the traditional radial approach (TRA) overlaps with the joint flexion. Recent reports have shown no significant difference in the complication rates between coronarography using the distal radial approach (DRA) and that using TRA. Read More

Association of Baseline Anemia with Mid-Term Clinical Outcomes in Patients Who Underwent Trans-Radial Primary Percutaneous Coronary Intervention.

Int Heart J 2021 Mar 6;62(2):256-263. Epub 2021 Mar 6.

Division of Cardiovascular Medicine, Saitama Medical Center, Jichi Medical University.

Radial access is recommended for primary percutaneous coronary intervention (PCI), because it has fewer bleeding complications than trans-femoral PCI. However, even if trans-radial PCI is chosen, patients with ST-elevation myocardial infarction (STEMI) presenting with anemia on admission might have poor clinical outcomes. The aim of this retrospective study was to investigate whether anemia on admission was associated with mid-term clinical outcomes in patients who underwent trans-radial primary PCI. Read More

Catheter Cardiovasc Interv 2021 Mar 2. Epub 2021 Mar 2.

Department of cardiology, Tabba Heart Institute Karachi, Karachi, Pakistan.

Objectives: Primary objectives: to compare radial artery occlusion rate (RAO) after cardiac catheterization between catecholamine-chitosan pad (InnoSEAL) and pneumatic compression device (PCD) and to compare difference in hemostasis time and radial monitoring termination time between two arms.

Effect of wrist dorsiflexion on ultrasound-guided radial artery catheterisation using dynamic needle tip positioning technique in adult patients: a randomised controlled clinical trial.

Emerg Med J 2021 Jan 26. Epub 2021 Jan 26.

Department of Anaesthesiology, The First Affiliated Hospital of Shantou University Medical College, Shantou, Guangdong, China

Background: It is generally recommended to keep the wrist joint mildly dorsiflexed during radial artery catheterisation. However, wrist dorsiflexion might decrease the success rate of radial artery catheterisation with dynamic needle tip positioning technique. Therefore, we assessed the success rates of two groups with or without wrist dorsiflexion by 5 cm wrist elevation in adult patients. Read More

Transradial Embolization, an Underused Type of Uterine Artery Embolization Approach: A Systematic Review.

Medicina (Kaunas) 2021 Jan 20;57(2). Epub 2021 Jan 20.

Department of Obstetrics and Gynecology, University of Medicine and Pharmacy "Gr. T. Popa", 700015 Iasi, Romania.

The most utilized approach for the embolization of uterine arteries is the transfemoral path. However, the transradial approach (TRA) has been gaining popularity among cardiologic interventions in the last years but only few studies have shown its applicability in uterine myoma treatment. The objective of this paper is to assess the feasibility, safety and efficacy of TRA when compared with the transbrachial, transulnar or transfemoral approach (TFA) for uterine arteries embolization (UAE).

Randomized Trial of VasoStat Versus TR Band Following Radial Artery Access for Catheterization Procedures.

J Invasive Cardiol 2021 Feb 21;33(2):E84-E90. Epub 2021 Jan 21.

Billings Clinic Heart and Vascular at Community Medical Center, 2827 Fort Missoula Road, Missoula, MT 59804-7408 USA.

Purpose: VasoStat (VS; Forge Medical) is a recently developed radial artery compression device (RCD) producing focused puncture-site pressure.

Acute Hand Ischemia and Digital Amputation After Transradial Coronary Intervention in a Patient With CREST Syndrome.

Thomas J Earl

Tex Heart Inst J 2020 08;47(4):319-321

Michigan Heart & Vascular Specialists, McLaren Northern Michigan, Petoskey, Michigan 49770.

The radial artery approach for coronary angiography and intervention is rapidly replacing the femoral artery approach, largely because it reduces bleeding and vascular access site complications. However, complications associated with transradial access warrant attention, notably radial artery occlusion. This report focuses on a case of radial artery occlusion after percutaneous coronary intervention in a 46-year-old woman with CREST (calcinosis, Raynaud phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia) syndrome, which ultimately led to acute hand ischemia necessitating amputation of her middle and index fingers.
