Causes of edema that are generalized to the whole body can cause edema in multiple organs and peripherally. For example, severe heart failure can cause pulmonary edema, pleural effusions, ascites and peripheral edema. Such severe systemic edema is called anasarca. In rare cases, a parvovirus B19 infection may cause generalized edemas. [9]
Pulmonary edema has multiple causes and is traditionally classified as cardiogenic (caused by the heart) or noncardiogenic (all other types not caused by the heart). [2] [3] Various laboratory tests (CBC, troponin, BNP, etc.) and imaging studies (chest x-ray, CT scan, ultrasound) are often used to diagnose and classify the cause of pulmonary edema.
Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
Cerebral edema is the cause of death in 5% of all patients with cerebral infarction and mortality after large ischemic strokes with cerebral edema is roughly 20 to 30% despite medical and surgical interventions. [9] [38] Cerebral edema usually occurs between the second and fifth day after onset of symptoms. [9]
HAE may also cause swelling in a variety of other locations, most commonly the limbs, genitals, neck, throat and face. The pain associated with these swellings varies from mildly uncomfortable to agonizing pain, depending on its location and severity. Predicting where and when the next episode of edema will occur is impossible.
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.
Then intracellular sodium and osmolarity increase, and there is an influx of water that causes cellular swelling. [9] [19] After the failure of the ATPase pumps, free radicals form and cause damage that complicates the edema. [13] Evidence against cytotoxic edema includes the high levels of hypoxemia (low bloodstream oxygen) needed to cause it ...
Negative-pressure pulmonary edema (NPPE), also known as Postobstructive Pulmonary Edema, is a clinical phenomenon that results from the generation of large negative pressures in the airways during attempted inspiration against some form of obstruction of the upper airways.
