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.

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Vascular diseases make up most cases of emergency hospitalization and carry a high mortality risk. Point-of-care ultrasound or POCUS enables accurate diagnosis of these diseases and shortens the time between detection of the cause and selection of appropriate treatment strategies, thus, reducing the patient mortality rate. POCUS offers a safe, low-cost, and less invasive bedside tool for examining arteries and veins, besides its...
FAQs
Two ultrasound views answer different clinical questions. B-mode produces a structural image of the carotid artery wall and lumen, allowing plaque-related changes to be seen. Doppler adds functional information by measuring blood-flow direction and velocity. Using both provides complementary evidence about anatomy and circulation during the same examination.
Blood-flow velocity is important because narrowing changes how blood moves through the artery. When Doppler detects abnormal velocities, the finding can indicate stenosis, meaning a narrowed arterial passage. Atherosclerotic plaque is often a source of this narrowing, so velocity measurements help connect flow behavior with structural disease and potential stroke risk.
Because carotid ultrasound does not use ionizing radiation, it can support repeated assessment when clinicians need follow-up over time. Its real-time capability also lets the examination evaluate arterial structure and blood flow as the study is performed. These features make it practical for ongoing vascular and cerebrovascular care.
During a carotid ultrasound examination, the assessment combines wall and lumen imaging with flow analysis. The operator can therefore examine structural changes and then consider whether the recorded direction and velocity are abnormal. This paired evaluation is important because stenosis is identified through the relationship between arterial appearance and blood-flow behavior.
Clinicians may use carotid ultrasound for screening and diagnosis of carotid artery disease, but its role extends beyond initial assessment. Findings can help guide treatment decisions and provide follow-up information over time. This range of uses allows one noninvasive examination to contribute to risk evaluation, clinical planning, and monitoring in vascular care.
Carotid ultrasound is especially relevant in cerebrovascular medicine because the carotid arteries supply blood to the brain. Detecting plaque-associated changes or flow patterns that suggest stenosis can add evidence when clinicians evaluate stroke risk. The examination therefore links local arterial findings with a broader neurological concern while remaining accessible and free of ionizing radiation.
