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 ...

The radial artery is a commonly used conduit for coronary artery bypass grafting. Long-term patency rates are at least as good and in some series are better than for saphenous vein grafts (1,2). owever, radial artery graft failure remains a ignificant problem (3), in particular in cases here radial conduits are used on smaller target essels or where there is significant competitive ow from a na...

A 73-year-old female patient underwent transradial coronary angiography with stable angina and signs of significant myocardial ischemia revealed by exercise stress test. After insertion of a 6F radial sheath into the right radial artery and intra-arterial administration of heparin plus verapamil, the hydrophilic guidewire could not be advanced under fluoroscopic guidance. Immediately afterwards...

A 42-year-old male admitted with a non-ST elevation myocardial infarction was referred for invasive angiographic assessment. Based on preprocedural assessment, the right radial artery approach was selected. Despite possessing none of the consensus risk factors for radial artery spasm, in addition to receiving standard arterial spasm prophylaxis and conscious sedation, the patient suffered very ...

Arterial variations in the arm are of potential clinical implications as it is a frequent site of injury and also involved in many surgical and invasive procedures. Variations in the vascular system of upper limbs are relatively common, and occur at the level of the axillary, brachial, radial, and ulnar arteries as well as in the palmar arches. During a dissection of the right upper extremity, ...

BACKGROUND Left internal thoracic artery-to left anterior descending artery grafting has become a fundamental part of coronary artery bypass grafting. This grafting has led to increased use of other arterial conduits, of which the radial artery is most popular. Whether radial grafting can be used in the emergency patient is not known. This study compares the short-term clinical evolution betwee...

The radial artery (RA) has emerged as an important arterial graft for coronary bypass surgery. With improving five-year patency rates and increasing uptake, great attention has been focused on the optimal conduit harvesting technique. We herein present our approach to RA harvesting. Prerequisites of a successful harvest include adherence to important anatomical landmarks, protection of the sens...

BACKGROUND Simultaneous measurement of ascending aorta and radial artery pressure shows that mean and diastolic pressures (DP) are in close agreement in normotensive adults, while systolic pressures (SP) are not. However, in the aortic pressure wave, a second systolic peak appears with increasing age and increases to represent the SP by age 32 yr, while in the radial artery, a second systolic d...

We report a 3-year-old boy with DS in whom radial artery pulsations were incidentally detected to be bilaterally absent. Bilateral ulnar artery and all other peripheral pulsations were normal. His blood pressure in right upper arm was normal, 96/66 mm Hg. Twodimensional echocardiography was normal. Doppler ultrasonography of the arterial trunks of the upper limbs suggested normal ulnar artery w...
