Only three of the patients had symptoms and signs of peripheral vascular insufficiency in the legs. Peak muscular flow after maximal work during ischaemia was reduced in the diabetic patients and decreased with increasing duration of diabetes. Medial calcification of the arteries was common, and it ...
The presence of thrombotic material results in the formation of calcifications, known as phleboliths, that can be painful when pressed. The calcifications can be seen on a plain radiograph and are a very useful sign for confirming a diagnosis of venous malformations and ruling out other ...
Cellular processes underlying these perturbations include altered vascular smooth muscle cell growth and apoptosis, fibrosis, hypercontractility and calcification. Inflammation, associated with macrophage infiltration and increased expression of redox-sensitive pro-inflammatory genes, also contributes to vascular ...
to determine the small vessel vascular condition distal to the ankle. Toe pressures may be useful in cases of unsuspected vascular disease and baseline diabetic foot assessment when falsely high ankle pressure can occur due to calcification. Results are indicators of healing potential in foot ulcers...
VitalScan Vascular+ also records the arm and ankle pulse volume waveforms (PVR) which provide pictorial evidence to aid a clinician's diagnosis; this is of particular value in patients prone to arterial calcification, such as diabetics. PVR analysis provides a second line of investigation that can...
Gangrene of lower legs, ischemic heart d/s and ischemic encepholopathy and others 1. Calcification 2. Plague ulceration 3. Intimal hemorrhage 4. Thrombosis and embolism 5. Aneurysm Risk Factors Age: 4-6th decades; but, the disease begins much younger age, slowly progressive. Sex: Men are ...
Emerging evidence from the last two decades has shown that vascular calcification (VC) is a regulated, cell-mediated process orchestrated by vascular smoot
[126,127,128]. Similar to ABI, TBI is calculated by dividing the toe systolic pressure by the brachial pressure. TBI is recommended as an alternative to ABI to counter unreliable elevated measures in the presence of medial artery calcification, which is particularly prevalent in people with ...
Many vascular graft structures have difficulty in conforming to the internal arterial wall, particularly since the wall can have a highly non-uniform surface as a result of atherosclerosis and calcification and is expanding and contracting with the patient's heartbeat and blood flow. Additionally, ...
Hence, catheter 34 may be used to provide information similar to that available through histology so as to indicate a composition of an atheroma (by identifying and location, for example, a fibrous cap, smooth muscle cells, a lipid pool, calcifications, and the like.) Intravascular ultrasound ...
