The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]
Middle cerebral artery Middle cerebral artery and its branches (patient has a hypoplastic A1 segment and an absent PCOM, resulting in a purely MCA angio from internal carotid artery injection) The middle cerebral artery divides into four segments, named by the region they supply as opposed to order of branching as the latter can be somewhat ...
[12] [24] There may also be a noticeable delay between the first heart sound (on auscultation) and the corresponding pulse in the carotid artery ('apical-carotid delay'). In a similar manner, there may be a delay between the appearance of each pulse in the brachial artery (in the arm) and the radial artery (in the wrist). [citation needed]

Coronary artery bypass surgery during mobilization (freeing) of the right coronary artery from its surrounding tissue, adipose tissue (yellow). The tube visible at the bottom is the aortic cannula (returns blood from the HLM). The tube above it (obscured by the surgeon on the right) is the venous cannula (receives blood from the body).
According to United States data, 2004, for about 65% of men and 47% of women, the first symptom of cardiovascular disease is myocardial infarction (heart attack) or sudden death (death within one hour of symptom onset). [citation needed] A significant proportion of artery flow-disrupting events occur at locations with less than 50% lumenal ...
In medicine, vein graft failure (VGF) is a condition in which vein grafts, which are used as alternative conduits in bypass surgeries (e.g. CABG), get occluded. Veins, mainly the great saphenous vein (GSV) are the most frequently used conduits in bypass surgeries (CABG or PABG), due to their ease of use and availability. [1]
Duplex scan of the common carotid artery. Doppler ultrasonography employs the Doppler effect to assess whether structures (usually blood) [57] [60] are moving towards or away from the probe, and their relative velocity. By calculating the frequency shift of a particular sample volume, flow in an artery or a jet of blood flow over a heart valve ...
