BACKGROUND The aim of the present study was to determine the respective influences of local pulse pressure and mean blood pressure on arterial remodeling in humans at 2 arterial sites: a central, predominantly elastic artery (the common carotid artery) and a peripheral muscular artery (the radial artery). METHODS AND RESULTS Forty-three healthy subjects and 124 never-treated hypertensive pati...

The radial artery access site offers many advantages in neuroangiography. Right vertebral artery access is readily obtained from a right radial artery approach. As with cardiology procedures, neuroradiology procedures may necessitate the use of lytic therapy or platelet inhibitors. Sheath removal can be done without reversal of anticoagulation or concerns about major bleeding complications. We ...

We report an unusual case of vasospasm of a grafted radial artery complicated with ventricular fibrillation during the postoperative course of coronary artery bypass graft surgery. To our knowledge this is the first documented case of a radial artery graft spasm leading to a severe arrhythmia. The arrhythmia resolved spontaneously. Radial artery graft spasm was demonstrated by angiography and w...

Background—Despite worse outcomes in diabetics after coronary artery bypass grafting surgery, studies have not examined graft patency in this high-risk group. This study examined the impact of diabetes on graft patency, 1-year postcoronary artery bypass grafting, using data from a multicenter randomized trial. Methods and Results—The Radial Artery Patency Study enrolled 561 patients undergoing ...

Radial artery catheters are commonly placed for continuous blood pressure monitoring, frequent arterial blood gas analysis, or frequent blood sampling for diagnostic testing. Radial artery cannulation can be challenging and ultrasound guidance has emerged as a valuable adjunct for the placement of radial artery catheters. The advantages of ultrasound guidance include: real-time visualization of...

The word “Brachial” is derived from the Greek word Brakion meaning ‘shorter’; brachium also means arm [1]. Normally brachial artery is a continuation of axillary artery at the inferior border of teres major muscle in axilla. Towards the distal end, it lies medial to the bicipital aponeurosis. At the level of neck of radius, in cubital fossa, artery bifurcates into two terminal branches, mediall...

OBJECTIVES The radial artery (RA) is increasingly being used as a coronary bypass graft. Results of a previous study using Doppler ultrasound and histopathologic examinations indicated that the RA has a higher incidence of preexisting intimal hyperplasia, medial calcification, and atherosclerosis than the internal thoracic artery. The aims of this study were to evaluate the use of computed tomo...

We describe the first Marfan syndrome case of non-traumatic bilateral radial artery aneurysms in the anatomical snuff box. A 74-year-old woman with Marfan syndrome had a pulsatile mass in her bilateral anatomical snuff box. The color Doppler ultrasonography showed an aneurysm of radial artery located in the bilateral anatomical snuff box. Resection of the right radial artery aneurysm was comple...

Anatomic variations of the radial artery and their effect on the use of the radial artery as a route for transradial coronary intervention (TRI) were studied. Ultrasonography of the radial artery was performed prospectively in 115 patients selected to undergo elective TRI. Anatomic variations were observed in 11 of 115 patients (9.6%). Variations included six tortuous configurations (5. 2%), tw...
