Variations in the arterial pattern of the upper limb are very common as observed in many cadaveric and angiographic studies. Knowledge of variations in the origin and course of the radial artery is important because they are used for many diagnostic procedures as well as vascular and reconstructive surgeries like coronary angiography, percutaneous coronary intervention and coronary artery bypas...

OBJECTIVE The right internal thoracic artery is being used infrequently despite favorable observational angiographic data. Conversely, the radial artery utilization has increased with only limited data available. The purpose of this paper is to re-evaluate the roles of the right internal thoracic artery and the radial artery grafts. METHODS We reviewed all ischemia-directed coronary angiograp...

Introduction Numerous review articles have described variations to the branching pattern of the vasculature [3, 8, 10] and innervation [1, 4,] in the upper limbs of cadavers. The classification of the arterial patterns that we used for this report corresponded to McCormick et al.’s [8] description of radial artery origin proximal to the intercondylar line. Multiple names have been given to this...

BACKGROUND Little information exists regarding mid-term and long-term patency of radial artery grafts. METHODS AND RESULTS We performed restudy coronary angiography at 5.2+/-0.4 years after surgery on 50 asymptomatic patients who had undergone coronary artery bypass graft surgery, using at least 1 radial artery graft, to determine both graft patency and presence of narrowing. We examined preo...

An otherwise fit and well 40-year-old left-handed male computer operator presented with a minimally symptomatic lump of 2 years duration in his non-dominant anatomical snuffbox. There was no history of trauma. This was pulsatile and did not transilluminate despite being referred as a ganglion. MRI scan confirmed the presence of a 1.5 cm radial artery aneurysm fed by the radial artery and draini...
