In this study an unusual combination of arterial, venous and neural variations discovered during dissection of cervical, axillary and brachial area of a cadaver is described. Variations are thoroughly described and literature is briefly reviewed. Lateral cord of brachial plexus was not formed; Eight Cervical root divided into anterior and posterior division before uniting with First Thoracic ro...

BACKGROUND Dilatation of the artery proximal to arteriovenous fistula (AF) is not well known but is a potential serious complication in patients for renal transplant. METHODS From 1991 until 2001, the diameters of the brachial arteries of 29 patients after successful renal transplantation and with existing AF were prospectively evaluated with ultrasound scan. Nine patients with longstanding A...

INTRODUCTION Pseudoaneurysms are a pulsatile hematoma caused by hemorrhage on soft tissues. It is an uncommon condition with many different etiologies. We report a case of a giant pseudoaneurysm caused by iatrogenic injury on the brachial artery. PRESENTATION OF CASE A 42 year-old male was submitted to our Vascular Surgery service with an enlargement of the right upper limb and a history of m...

Aim: To compare brachial artery flow-mediated dilation (FMD) in subjects who use smokeless tobacco, smoke cigarettes, or do not use any tobacco product. Materials and methods: In the study, participants were 35 Maras powder users, 36 cigarette smokers and 30 nontobacco user subjects. Blood samples were collected and hematological parameters and lipid parameters were measured. Homocystein and hs...

BACKGROUND Familial dysautonomia (FD) is a rare hereditary disease characterized by loss of afferent autonomic neural fiber signaling and consequent profound impairment of arterial baroreflex function and blood pressure regulation. Whether vascular endothelial dysfunction contributes to defective vasomotor control in this form of afferent autonomic failure is not known. METHODS We assessed bl...

OBJECTIVE To compare flow-mediated vasodilatation in patients with anorexia nervosa and healthy subjects. BACKGROUND Endothelial dysfunction is present in the patients with anorexia nervosa. However, flow-mediated vasodilatation in the patients with anorexia nervosa in comparison with control subjects has not been yet evaluated. METHODS Flow-mediated vasodilatation in the brachial artery wa...

Objective To investigate the potential correlation between sonographically measured mesenteric fat thickness (MFT) and brachial artery flow-mediated dilation (FMD) in a sample of healthy Chinese male young adults. Methods Healthy male participants were recruited from Hong Kong Polytechnic University for this prospective observational study. The physical activity readiness questionnaire and ultr...

The median nerve is usually formed just lateral to the third part of the axillary artery by the union of its medial and lateral roots coming from medial and lateral cords of the brachial plexus respectively. It then descends down in the front of the arm and crosses superficial to the brachial artery from lateral to medial side. It enters the cubital fossa along with the brachial artery. Normall...

Since systolic pressure is governed by the rate of ventricular ejection and the rigidity of the aortic wall, antihypertensive agents may have different effects on systolic and diastolic pressure. Despite an adequate decrease in diastolic pressure, systolic pressure may remain elevated due to structural alterations of large arteries. In the present study, a procedure is described to distinguish ...

During a 7-year period approximately 700 left heart cardiac catheterizations were carried out via open brachial arteriotomy. Of these, 25 patients with a missing or weak radial pulse after catheterization were referred for operation. Despite minimal early ischaemic symptoms and signs, all 25 patients had a complete occlusion of the brachial artery at the site of the arteriotomy. Commonest cause...
