This describes a partial carotid ligation surgery, which causes disturbed flow conditions and subsequent atherosclerosis development (in two weeks) with intraplaque neo-vascularization (in four weeks) in the mouse common carotid artery. We also describe a novel method of RNA isolation from the carotid intima, providing high purity endothelial RNA.

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level. The pulse serves as a clinical indicator...

FAQs
Rate and rhythm show how consistently cardiac activity is represented at the artery, while amplitude describes the strength of the palpable expansion. Presence or absence adds another clinically relevant observation. Considering these features together helps clinicians evaluate cardiac output and arterial perfusion more completely than judging the pulse by rate alone.
Symmetry provides a comparison between the two sides of arterial pulsation. Differences in the carotid pulse can suggest that blood flow is not reaching both sides equally, while a diminished pulse may indicate reduced arterial perfusion. Recording symmetry alongside amplitude therefore adds context to the assessment of cardiovascular function and possible circulatory abnormality.
Because the carotid pulse reflects ventricular ejection, its timing relative to heart sounds can add information that palpation alone does not provide. Clinicians use this temporal relationship to support evaluation of valve disorders and other hemodynamic abnormalities, linking an arterial finding with events in the cardiac cycle. This makes pulse timing useful when altered blood flow is suspected.
The clinician gently palpates the side of the neck beside the trachea, using enough pressure to detect the pulse without excessive compression. The two carotid arteries should not be pressed simultaneously. During the examination, the clinician records presence, rate, rhythm, amplitude, and whether the findings appear symmetric, producing a structured assessment rather than a single observation.
In an emergency, checking the carotid pulse can rapidly establish whether circulation is present and provide immediate information about its quality. The examiner can note whether the pulse is detectable and characterize its rate, rhythm, and amplitude. These observations help evaluate cardiovascular function and arterial perfusion when rapid clinical assessment is required.
An abnormal examination can point to more than an unusual heartbeat. A diminished finding may raise concern about reduced arterial blood flow, whereas an irregular rhythm can indicate altered cardiac activity. When combined with timing relative to heart sounds, carotid findings may also support recognition of valve disorders or other hemodynamic abnormalities during clinical evaluation.
