Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...

The prominence of the hand function is underlined fundamentally by its rich vascular system. The superficial palmar arch incredibly provides hand with the blood supply, which is normally formed by the ulnar artery and superficial palmar branch of the radial artery. In the current case, the unilateral absence of superficial palmar arch with the rare presence of the median artery was reported, wh...

vascular endothelial growth factor (vegf) is a multifunctional cytokine with distinct functions in angiogenesis, lymphangiogenesis, vascular permeability, and hematopoiesis. vegf is a highly conserved, disulfide-bonded dimeric glycoprotein of 34 to 45 kda produced by several cell types including fibroblasts, neutrophils, endothelial cells, and peripheral blood mononuclear cells, particularly t ...

Recent genome-wide association studies have identified hundreds of genetic loci as being associated with vascular diseases or traits and their risk factors. Many of the loci uncovered represent novel discoveries with no obvious candidate genes and molecular mechanisms, testifying to the complexity of vascular diseases. To understand the functional consequences of genetic variations and help pin...
