BACKGROUND Flow-mediated dilation (FMD) following reactive hyperaemia can use different time-point measures for baseline diameter. The aim of this study is to compare preocclusion, occlusion and postocclusion baseline brachial artery measurements on the calculation of peak FMD. STUDY DESIGN Ultrasound imaging of the brachial artery following reactive hyperaemia was conducted in 418 children a...

We performed simultaneous noninvasive measurements of common carotid artery and brachial artery hemodynamics in nine normal subjects and 10 subjects with sustained essential hypertension. In hypertensive subjects, brachial artery blood flow and forearm vascular resistance were in the normal range while carotid artery blood flow and carotid artery resistance were decreased and increased, respect...

We present a case regarding the anomalous branching in the third part of the axillary artery on the left side in a 35-year-old male Nepalese cadaver. In the third part the axillary artery divided into superficial brachial and deep brachial arteries. The superficial brachial artery continued in the arm without giving any branches and ended in the cubital fossa dividing into radial and ulnar arte...

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...

Radial artery diameter decreases when a wrist cuff is inflated to stop blood flow to distal tissue. This phenomenon, referred to as low flow-mediated vasoconstriction (L-FMC), was proposed as a vascular function test. Recommendations that L-FMC be measured concurrently with flow-mediated dilation (FMD) were based on radial artery data. However, cardiovascular disease prediction studies traditio...

The axillary artery is the continuation of the subclavian artery beyond the outer border of the first rib. The artery is divided into three parts by the pectoralis minor muscle. The first part of the artery gives superior thoracic artery. The second part of the artery gives lateral thoracic and thoracoacromial branches. The third part gives subscapular, anterior circumflex and posterior circumf...

Introduction The brachial plexus is a complex structure which is divided into roots, trunks, divisions and cords. The brachial plexus is formed by the union of ventral rami of C5, C6, C7, C8 and greater part of T1.These ventral rami are the roots of brachial plexus, almost equal in size but variable in their mode of junction. Ventral rami of C5 and C6 unite at the lateral border of the scalenus...

BACKGROUND Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients. METHODS AND RESULTS One hundred ...

Anatomical variations in the formation, course and distribution of brachial plexus are well documented. The present report describes some rare variations with regard to relation of cords of brachial plexus, median and ulnar nerves with the third part of axillary artery and brachial artery in the left upper limb of an adult male cadaver. All three cords of brachial plexus were noted to be latera...
