Lipohyalinosis is a cerebral small vessel disease affecting the small arteries, arterioles or capillaries in the brain.Originally defined by C. Miller Fisher as 'segmental arteriolar wall disorganisation', it is characterized by vessel wall thickening and a resultant reduction in luminal diameter.
Secondly, high blood pressure is a silent disease and thus it is vital for all diabetics to regularly check their blood pressure or have it checked at a doctor's office on a regular basis. The American Diabetes Association recommends that all diabetics get their blood pressure measured by a health care professional at least 2-5 times a year. [94]
The explicit treatment of the boundary condition may be circumvented by using a staggered grid and requiring that + vanish at the pressure nodes that are adjacent to the boundaries. A distinguishing feature of Chorin's projection method is that the velocity field is forced to satisfy a discrete continuity constraint at the end of each time step.
Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
Pulmonary artery stenosis (PAS) is a narrowing of the pulmonary artery.The pulmonary artery is a blood vessel moving blood from the right side of the heart to the lungs. . This narrowing can be due to many causes, including infection during pregnancy, a congenital heart defect, a problem with blood clotting in childhood or early adulthood, or a genetic ch
The above equations calculate the steady state mass flow rate for the pressure and temperature existing in the upstream pressure source. If the gas is being released from a closed high-pressure vessel, the above steady state equations may be used to approximate the initial mass flow rate. Subsequently, the mass flow rate decreases during the ...
It affects all of the vessels: very small blood vessels (capillaries), medium-size blood vessels (arterioles and venules), or large blood vessels (arteries and veins). If blood flow in a vessel with vasculitis is reduced or stopped, the parts of the body that receive blood from that vessel begins to die, resulting in a stroke .
Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). [1] This also refers to the condition of damage or rupture of small blood vessels. The best known and most prevalent angiopathy is diabetic angiopathy , a common complication of chronic diabetes .
