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...

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...

We present a patient with a failed radial coronary angioplasty as a result of bilateral brachioradial arteries, the radial arteries anomalously originating from the axillary arteries. We review the literature concerning abnormal origins of the radial artery and propose the left ulnar artery as optimal access of choice in cases with a right brachioradial artery of relatively small size in its pr...

(Reviewer 1): You started the procedure with a 6 fr right femoral artery sheath. Considering the standard size of the sheath, why didn't you choose a radial artery access? As previously published in this paper: Seven french radial artery access for PCI: a prospective single-center experience, a larger radial artery sheath is feasible and well tolerated by the patients. (please mention this stud...

The word “Brachial” is derived from the Greek word Brakion meaning ‘shorter’; brachium also means arm [1]. Normally brachial artery is a continuation of axillary artery at the inferior border of teres major muscle in axilla. Towards the distal end, it lies medial to the bicipital aponeurosis. At the level of neck of radius, in cubital fossa, artery bifurcates into two terminal branches, mediall...

The use of radial artery grafts for coronary bypass surgery is becoming more frequent. However, experience with percutaneous coronary intervention for radial artery graft failure is limited. We describe a patient with a radial artery graft in whom angina reappeared because of de novo stenosis in the graft. The patient was successfully treated with balloon angioplasty and stenting. At 6 months h...

OBJECTIVES Superficial ulnar artery is a vascular anomaly that may be encountered during elevation of forearm flaps for head and neck reconstruction. This anomaly should be considered in patients with a positive Allen's test. STUDY DESIGN Case report and retrospective review of forearm flaps performed at our institution. METHODS A 72-year-old man with a history of total laryngectomy present...
