Hydrostatic pressure within blood vessels tends to cause water to filter out into the tissue. This leads to a difference in protein concentration between blood plasma and tissue. As a result, the colloidal or oncotic pressure of the higher level of protein in the plasma tends to draw water back into the blood vessels from the tissue. Starling's ...
The causes of macular edema are numerous and different causes may be inter-related. It is commonly associated with diabetes.Chronic or uncontrolled diabetes type 2 can affect peripheral blood vessels including those of the retina which may leak fluid, blood and occasionally fats into the retina causing it to swell.
Lymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized swelling caused by a compromised lymphatic system. [2] The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream .
It happens because of inflammation in the skin and blood vessels, leading to blood leakage into the skin. Treatment: Petechiae marks will go away with time while undergoing treatment for the root ...
It is possible for cardiogenic pulmonary edema to occur together with cardiogenic shock, in which the cardiac output is insufficient to sustain an adequate blood pressure to the lungs. This can be treated with inotropic agents or by intra-aortic balloon pump , but this is regarded as temporary treatment while the underlying cause is addressed ...
The condition is commonly associated with vascular and cardiac changes associated with aging but can be caused by many other conditions, including congestive heart failure, kidney failure, liver cirrhosis, portal hypertension, trauma, alcoholism, altitude sickness, pregnancy, hypertension, sickle cell anemia, a compromised lymphatic system or merely long periods of time sitting or standing ...
Heat edema is a cutaneous condition characterized by dependent edema from vasodilatory pooling. [2] Heat causes the blood vessels to expand (dilate), so body fluid moves into the hands or legs by gravity. The balance of salt in the body is also a risk factor for heat edema.
Elevated vascular permeability can allow excess fluid to leave blood vessels and collect in tissues resulting in edema; vasodilation prevents blood vessels from constricting to adapt to reduced volume in the vessels, causing low blood pressure and septic shock. [11] In the case of inflammation, vasodilation is caused by cytokines. [7]
