Studies of peripheral blood vessels in humans have focused primarily on regulation of blood flow and vascular resistance, which are thought to reflect small vessel caliber. Recent studies in animals have identified flow-mediated and neurogenic changes in large artery diameter. This study tested for flow-mediated dilatation and reflex constriction of the brachial artery in humans. A dual-crystal...

this study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especiallyin brachial enlargement. sixteen adult female rats were divided into two groups. diabetes was induced in one group by alloxan agent. both groups became pregnant by natural matting. on days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offsprin...

atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. the present report describes a case of variation of the median nerve observed in the iranian male cadaver during routine trial dissection. there are three roots for median nerve. median nerve is formed by joining two lateral and medial cords of brachial plexus. third root of ...

We present the case of a 68-year-old woman, referred to our department for critical upper limb ischemia, which had occurred a few days after homolateral surgical ligamentotomy for carpal tunnel syndrome, diagnosed and confirmed by electromyography, and performed with a brachial tourniquet. The patient was later admitted for subsequent progressive necrosis of the first three fingers of the left ...

Introduction: Brachial plexus schwannomas are extremely rare tumours of the head and neck region accounting for less than 5 % overall. Due to its rarity and anatomic complexity of the brachial plexus, schwannomas in this region present a diagnostic and surgical challenge to the surgeon.   Case Report: We present a case of a 56-year-old female who presented with a slow gr...

Primary tumors of the brachial plexus region are rare and granular cell tumors arising from the brachial plexus region is an extremely rare disease. We present a case of granular cell tumor arising from of the brachial plexus which appeared to be a usual presentation of nerve sheath tumor before the pathological confirmation. We report a granular cell tumor of the brachial plexus with literatur...

Imaging of the brachial plexus in infants and young children with birth-related brachial palsy may become more frequent in view of recent renewed interest in the surgical repair of these injuries [1). The usefulness of MR for imaging the brachial plexus has been described recently [2, 3). MR may provide an alternative, noninvasive means of studying patients with obstetric palsy. To our knowledg...

Pressure measured with a cuff and sphygmomanometer in the brachial artery is accepted as an important predictor of future cardiovascular risk. However, systolic pressure varies throughout the arterial tree, such that aortic (central) systolic pressure is actually lower than corresponding brachial values, although this difference is highly variable between individuals. Emerging evidence now sugg...

OBJECTIVE To examine the effect of handgrip exercise induced ischaemia on non-invasive assessment of endothelial function in the brachial artery. DESIGN AND SETTING High frequency ultrasound was used to measure brachial artery diameter at rest and after reactive hyperaemia induced by forearm cuff occlusion with and without handgrip exercise induced ischaemia. SUBJECTS 10 healthy subjects, <...
