Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
Cerebral edema has been traditional classified into two major sub-types: cytotoxic and vasogenic cerebral edema. [1] This simple classification helps guide medical decision making and treatment of patients affected with cerebral edema. [3]
The "vasogenic" theory posits that elevated blood pressure overcomes the normal capability of blood vessels in the brain to maintain a normal cerebral blood flow. The excessive pressure damages the endothelial layer and the blood–brain barrier, leading to swelling (edema).
While there is strong evidence that vasogenic edema plays a major role in HACE, cytotoxic edema, cellular retention of fluids, may contribute as well. [13] [18] Cytotoxic edema may be caused by the failure of cellular ion pumps, which results from hypoxia. Then intracellular sodium and osmolarity increase, and there is an influx of water that ...
Clinical manifestations of intraparenchymal hemorrhage are determined by the size and location of hemorrhage, but may include the following: [citation needed] Hypertension, fever, or cardiac arrhythmias
Cerebral edema is mainly classified into cytotoxic edema, vasogenic edema and interstitial edema. Cytotoxic edema affects both the white and gray matter and results from the swelling of cellular elements such as neurons, glia and endothelial cells. Vasogenic edema affects white matter and results from blood brain barrier (BBB) breakdown ...

Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs.
