ABSTRACT The transradial approach is indicated to reduce the risk of death, vascular complications, or bleeding. In patients with stable ischemic heart disease, the radial approach is recommended to reduce vascular complications and bleeding on access site. The complications are rare, and hematoma, perforation, and pseudoaneurysm (very rarely) of the radial artery may occur. This case report describes a rare case of left radial artery pseudoaneurysm associated with compartment syndrome in the left forearm after elective catheterization. The diagnosis was […]

ABSTRACT Background External compressive devices after radial puncture for cardiac catheterization and percutaneous coronary intervention aim at hemostasis, patient comfort, and safety. The objective of the study was to evaluate patients undergoing invasive coronary procedures by radial approach, in which a low-cost compressive dressing developed at the service was used, assessing its safety and the occurrence of complications. Methods Patients undergoing coronary angiography and percutaneous coronary intervention, evaluated at the time of removal of compressive dressing and after 7 days, […]

ABSTRACT Through the efforts of dedicated interventionists, catheterization of the cardiovascular system by transradial method has been recognized as the gold standard due to the several advantages associated with it, such as early ambulation, decline in bleeding and in various other vascular complications. It has successfully turned as an alternative to femoral access. The huge experience of interventionists has helped in understanding the anatomical impediments that can result in many technical issues and complications associated with the transradial approach. A […]

ABSTRACT Background The benefit of transradial catheterization is well established in female patients. Women undergoing transradial catheterization exams present with unique challenges. The occurrence of radial artery spasm and occlusion after the procedure is higher in women. The objective of this study was to evaluate the benefit of nitroglycerin in reducing radial artery spasm and occlusion in women undergoing transradial catheterization. Methods This was a 2×2 factorial randomized, multicenter, prospective, double-blinded study. Participants were randomized to nitroglycerin 500mcg or placebo […]

ABSTRACT Background The transradial access has gained great prominence in interventional coronary procedures due to lower complication rates, especially when the radial artery is punctured distally, in the anatomical snuffbox. The objective of this study was to analyze the complication and crossover rates of the access routes in invasive coronary procedures, comparing the distal radial artery to the proximal transradial route in the styloid process and the transfemoral access. Methods This was a prospective, observational, and single-center cohort study. The […]

Abstract Background: The use of the distal radial access for invasive coronary procedures has been rapidly adopted by the medical community, but with no evaluation of efficacy and safety outcomes of this approach. The objective was to evaluate the rate of radial artery occlusion involved in this technique, using Doppler ultrasound. Methods: This was an observational, retrospective study involving patients undergoing invasive diagnostic or therapeutic coronary procedures via distal radial access, with assessment of the radial artery patency by Doppler […]

ABSTRACT The use of the radial artery as a vascular access route for performing percutaneous coronary procedures has been reinforced based on consistent data attesting to its efficacy, greater safety and comfort for patients, when compared to femoral or brachial approaches. However, decreasing the rate of acute or chronic occlusion of the radial artery after the use thereof remains a challenge. The most recently adopted strategy to minimize the risk of arterial occlusion consists of puncturing the radial artery in […]

ABSTRACT The choice of the vascular access for coronary angiography or angioplasty is a function of the operator´s experience, of the presence of arterial pulse at the chosen site, and of the clinical status of the patient. The femoral approach should still be preferable in cases of higher angiographic complexity that require large-bore guide catheters, while radial access should be the approach for elective coronary angiography and acute myocardial infarction, taking into consideration the reduction in overall events. When the […]

ABSTRACT Background When it is not suitable to use the radial access in invasive coronary procedures, the ulnar technique is a feasible and safe alternative. The objective of the present study was to characterize the relevance of the ulnar technique in the daily practice of a center that adopts the radial strategy as the first option. Methods The sample was extracted from a single-center prospective registry, from May 2008 to October 2018, including all patients undergoing invasive coronary procedures in […]

ABSTRACT Background Ad hoc percutaneous coronary intervention via radial access has become frequent in interventional cardiology services, with reduced bleeding rates, vascular complications and costs. There are few reports in the medical literature on radiological exposure rates (kerma area product − Kap, and incident air kerma − Iak) in these procedures, when they are performed via radial access. The objective of the study was to compare radiological variables in staged percutaneous coronary interventions with ad hoc interventions via radial access. […]
