The vein can be identified near the saphenous ostium by a typical ultrasonographic image the so-called Mickey mouse sign (the 2 ears will be the GSV and the ASV, the head is the common femoral vein). When the ultrasonography is performed, we can see it running across the anterior face of the thigh in a plan outside the femoral vessels, the GSV ...
The use of ultrasonography in a medical application was first used in the late 1940s in the United States. This use was soon followed in other countries with further research and development being carried out. The first report on Doppler ultrasound as a diagnostic tool for vascular disease was published in 1967–1968.
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals.

Atherosclerosis represents around 85% of all deaths from cardiovascular diseases due to the buildup of plaque. [33] Coronary artery disease that often follows after atherosclerosis can cause heart attacks or cardiac arrest, resulting in 370,000 worldwide deaths in 2022. [34] In 2019, around 17.9 million people died from cardiovascular diseases.
Vascular system of the kidney is also developed with the development of nephrons, with large vessels branching from the dorsal aorta. [176] In some mammals, kidney organogenesis ends before birth, while in others it may continue for some time into the postpartum period [177] (for example, in rodents it ends about a week after birth). [178]
Electron micrograph of ventricular (left) and atrial myocyte (right) showing location of ANP storage granules in a mouse model. Captured by Dr. Stephen C. Pang from Queen's University . Atrial natriuretic peptide ( ANP ) or atrial natriuretic factor ( ANF ) is a natriuretic peptide hormone secreted from the cardiac atria that in humans is ...
The anterior spinal cord, which makes up 2/3 of the entire spinal cord, gets its blood supply from the anterior spinal artery.This artery in turn receives its blood from the different radiculospinal branches, which are formed from the aorta and vertebral arteries.
Vascular cell adhesion protein 1 also known as vascular cell adhesion molecule 1 (VCAM-1) or cluster of differentiation 106 (CD106) is a protein that in humans is encoded by the VCAM1 gene. [5] VCAM-1 functions as a cell adhesion molecule .
