Radial artery is one of the smaller terminal branches of brachial artery which originates at the level of neck of radius. During routine dissection, a lot of variations in the arterial pattern of the upper limb were encountered which ignited our curiosity to review literature regarding the normal anatomy and variations of radial artery. There is marked difference in the arrangement of these art...

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...
