The percutaneous transradial approach for cardiac catheterization has been shown to be a safe alternative to the femoral artery approach, owing to the favorable anatomical relation of the radial artery to surrounding structures and the dual blood supply to the hand. With the miniaturization of coronary interventional equipment, Kiemeneij and Laarmen have advocated the technique as an alternativ...

Recognizing the arterial variations of human upper extremities is of potential clinical practice because this area is involved in arterial handling and invasive medical procedure. During dissection of the left upper limb of a 35-year-old male embalmed cadaver, we saw brachial artery bifurcation in the middle third of proximal portion of the arm. Its medial branch descended along the medial side...

BACKGROUND With the expanded use of the radial artery as a bypass conduit in patients undergoing coronary artery bypass grafting, an endoscopic radial artery harvesting method was used to improve esthetics and patient acceptance, and possibly, to decrease hand neurologic complications. METHODS After informed consent and confirmation of adequate ulnar collateral blood flow, 300 consecutive pat...

AIMS To determine the reproducibility of flow-mediated dilation (FMD) and nitrate-mediated dilation (NMD) in the assessment of radial artery vasomotor function, and to examine the effect of transradial catheterisation on radial artery injury and recovery. METHODS Radial artery FMD and NMD were examined in 20 volunteers and 20 patients on four occasions (two visits at least 24 hours apart, wit...

32 Introduction and objective. Treatment of acute myocardial infarction by percutaneous coronary intervention with stenting leads to excellent immediate clinical results and a good prognosis. The aim of this study was to compare in this selected population the safety and effectiveness of radial artery access versus femoral artery access. Patients and method. Between May 2001 and June 2003, 162 ...

PURPOSE Monitoring of blood pressure (BP) during procedures is variable, depending on multiple factors. Common methods include sphygmomanometer (BP cuff), separate radial artery catheterization, and side port monitoring of an indwelling sheath. Each means of monitoring has disadvantages, including time consumption, added risk, and signal dampening due to multiple factors. We sought an alternati...

OBJECTIVES The purpose of this study was to present radial and saphenous vein graft (SVG) occlusion results more than 5 years following coronary artery bypass surgery. BACKGROUND In the RAPS (Radial Artery Patency Study) study, complete graft occlusion was less frequent in radial artery compared with SVG 1 year post-operatively while functional occlusion (Thrombolysis In Myocardial Infarction...

The prominence of the hand function is underlined fundamentally by its rich vascular system. The superficial palmar arch incredibly provides hand with the blood supply, which is normally formed by the ulnar artery and superficial palmar branch of the radial artery. In the current case, the unilateral absence of superficial palmar arch with the rare presence of the median artery was reported, wh...

The incidence of superficial arteries was studied in 68 (38 right and 30 left) upper extremities. One right limb of an adult male presented a superficial arterial pattern (2.63%, total 1.47%) resembling a superficial brachio-ulno-radial artery (SBUR). The median nerve crossed the superficial brachial artery (SBA) from the posterior to the medial side and again posterior to the same at the cubit...
