OBJECTIVES To determine whether patient sex makes a difference to in-hospital mortality and survival in patients undergoing isolated coronary artery bypass graft surgery (CABG) receiving a radial artery graft. METHODS Analysis of consecutive patients on a validated prospective cardiac surgery database was performed for patients undergoing isolated CABG. Uni- and multivariate analyses were per...

Worldwide, there is increasing interest in transradial intervention, as it appears safer, more cost-effective and is the preferred access route for patients over transfemoral intervention. The favorable neuroanatomical relationships of the radial artery mean that access-site complications are extremely rare. However, radial access-site complications do occur and we report a case of radial arter...

Objective: Doppler ultrasound and digital plethysmography are used at our institution to determine the suitability of the radial artery for harvest prior to coronary artery bypass grafting (CABG). The purpose of this study is to determine the value of this preoperative evaluation. Methods: A retrospective analysis of non-invasive radial artery testing was performed on 187 CABG patients. Criteri...

BACKGROUND In the past decade, the radial artery has frequently been used for coronary bypass surgery despite concern regarding the possibility of graft spasm. Graft patency is a key predictor of long-term survival. We therefore sought to determine the relative patency rate of radial-artery and saphenous-vein grafts in a randomized trial in which we controlled for bias in the selection of patie...

The use of radial arteries as an arterial bypass conduit is an invasive procedure which is becoming popular among various medical centres. The greatest risk associated with harvesting the radial artery is ischaemia of the soft tissues of the hand. In this study we dissected 200 hands derived from 100 formalin-fixed cadavers in order to identify arterial patterns that will allow safe removal of ...

BACKGROUND We evaluated the posterior tibial artery as an alternative arterial cannulation site to the radial artery in small children. METHODS A two-stage study was conducted. First, we evaluated the anatomical characteristics of the posterior tibial artery compared with the radial and dorsalis pedis arteries. Next, a parallel-arm single-blind randomized controlled study compared the initial...

Aberrant systemic arteries supplying the intralobar pulmonary sequestration can become dilated and have atherosclerotic change. Computed tomography is very useful in demonstrating the aberrant artery. We report a case of intralobar pulmonary sequestration with giant branching aneurysmal aberrant artery, and demonstrated the discontinuity of the bronchus by 64-slice computed tomography, which ha...

BACKGROUND AND OBJECTIVES Several studies have demonstrated a significant difference between the aortic and radial artery pressures in patients on cardiopulmonary bypass (CPB). The objectives of this study were to evaluate the behavior of the aorta-to-radial artery pressure gradient during myocardial revascularization (MR) with CPB and its correlation with the systemic vascular resistance. ME...

BACKGROUND To describe the radial artery and its variants in origin, branching pattern, mode of termination, and measurements of its length and external diameter. MATERIAL AND METHODS One hundred upper limbs of 30 men and 20 women adult cadavers were used in this study. The cadavers were obtained from the Anatomy Department, Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia...
