Brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. The aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the Japanese quail. The different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old Japanese quail; (n = 6) and both sexes. Luminal diameter, th...

The risk associated with arterial thromboembolism (ATE) increases with the presence of anti-vascular endothelial growth factor (VEGF). We are reporting a case of transient ischemic attack (TIA) due to stenosis of the carotid and brachiocephalic arteries following long-term treatment with sorafenib for renal cell carcinoma (RCC). The patient is a non-smoker with no known comorbidities and had no...

Left brachiocephalic vein begins from junction of left subclavian and left internal jugular vein posterior to medial end of left clavicle. It crosses to the right moving slightly in inferior direction and joins with right brachiocephalic vein to form superior vena cava. During its oblique course it crosses the left subclavian artery, left common carotid artery and brachiocephalic trunk in the s...

In a 37 year-old woman with Takayasu's arteriopathy angiography revealed occlusion of right coronary artery (RCA), brachiocephalic trunk and left carotid artery (LCA), as well as aortic regurgitation. She underwent a complex cardiovascular surgery consisting of aortic valve implantation, RCA grafting and implantation of vascular bifurcated graft anastomosed between ascending aorta and brachioce...

A rare clinical variant of angina manifestation as part the coronary steal syndrome in a patient with prior bilateral artery bypass grafting and subtotal brachiocephalic trunk stenosis is considered.

Variations of the branches of aortic arch are due to alteration in the development of certain branchial arch arteries during embryonic period. Knowledge of these variations is important during aortic instrumentation, thoracic, and neck surgeries. In the present study we observed these variations in fifty-two cadavers from Indian populations. In thirty-three (63.5%) cadavers, the aortic arch sho...

OBJECTIVE To better understand the mechanism of stroke during cardiopulmonary bypass, it is necessary to obtain information on the location of turbulence, wall pressure, and flow distribution within the aortic arch. METHODS Blood flow was numerically simulated using the finite element method in the following representative case: a curved arterial cannula was inserted into the anterior wall of...

The internal thoracic artery (ATI) of rats was macroscopically studied. In this study, the overall features of the artery were virtually elucidated in entirety. The artery was found to arise from the subclavian artery in the thoracic cavity and to immediately break up into the following branches: (1) the pericardiacophrenic artery, (2) the superior epigastric artery, (3) the thymic branch, (4) ...

OBJECTIVE To investigate the ability of high-resolution MRI to determine composition and microanatomy of atherosclerosis in mouse aortic root and brachiocephalic artery. METHODS AND RESULTS Aortic root and brachiocephalic arteries of apolipoprotein E knockout (apoE-/-) mice fed Western diet for 10, 20, or 30 weeks were imaged ex vivo (11.7 T; 3D multiecho sequence; resolution 47x47x62.5 micro...
