coagulative necrosis

Coagulative necrosis of the hepatocytes can occur around the central vein.

Dry gangrene is actually a form of coagulative necrosis.

New technique for liver resection using heat coagulative necrosis.

In coagulative necrosis the architecture of dead tissue is preserved for at least a couple of days.

Coagulative necrosis occurs primarily in tissues such the kidney, heart and adrenal glands.

Coagulative necrosis is a type of accidental cell death typically caused by ischemia or infarction.

Coagulative necrosis occurs here.

Under the microscope, myocardial infarction presents as a circumscribed area of ischemic, coagulative necrosis (cell death).

Wet gangrene is coagulative necrosis progressing to liquefactive necrosis.

One exception to coagulative necrosis is the brain, which undergoes liquefactive necrosis in response to infarction.

Coagulative necrosis is most commonly caused by conditions that do not involve severe trauma, toxins or an acute or chronic immune response.

The energy delivered with each sonication is capable of raising the temperature of the tissue upwards of 65 degrees Celsius resulting in coagulative necrosis.

Ischemic coagulative necrosis results and fibrosis of the affected area develops from the reparative response beginning at the preserved margins and working its way inwards.

Liquefactive necrosis (or colliquative necrosis), in contrast to coagulative necrosis, is characterized by the digestion of dead cells to form a viscous liquid mass.

At the focus of this ultrasound energy, the temperature can reach excesses of 80 C which results in nearly spontaneous coagulative necrosis or cell death without harming neighboring cells.

The cone-shaped ultrasound beam penetrates through soft tissue and produces well defined regions of protein denaturation, irreversible cell damage, and coagulative necrosis, at specific target locations.

The macroscopic appearance of an area of coagulative necrosis is a pale segment of tissue contrasting against surrounding well vascularised tissue and is dry on cut surface.

Coagulative necrosis is characterized by the formation of a gelatinous (gel-like) substance in dead tissues in which the architecture of the tissue is maintained, and can be observed by light microscopy.

These central regions begin to die through coagulative necrosis, though they also retain some of the structural characteristics of previously normal tissues, enabling a distinction from the granulomas of tuberculosis where caseous necrosis obliterates preexisting structures.

It is important to note that while ischemia in most tissues of the body will cause coagulative necrosis, in the central nervous system ischemia causes liquefactive necrosis as there is very little structural framework in neural tissue.
