Twisting of any portion of the intestines may cut off the supply of blood to a loop of bowel (strangulation), reducing the flow of oxygen to bowel tissue (ischemia) and leading to tissue death (gangrene).
If malrotation or duodenal volvulus has caused the blood supply to be cut off in a portion of the intestine before surgery, death of intestinal tissue can result and life-threatening gangrene can develop.
Louis Pasteur first observed garlic's antibacterial qualities in 1858, and until World War II is was routinely used to prevent gangrene in patients with infected wounds.
Strangulation occurs in about 25 percent of bowel obstruction cases and is a serious condition that can progress to gangrene within six to 12 hours.
He died of gangrene of the leg in his seventieth year.
Nevertheless, gangrene is nothing more or less than the putrefactive fermentation of an animal tissue still attached to the body.

- Symmetrical gangrene of toes (3 months' duration), showing the sharp " line rof demarcation " between the mummified toes and the more healthy tissue.
In the gangrenous form various parts of the body underwent gangrene as a consequence of the arrest of bloodsupply produced by the action of sphacelinic acid on the arteries.
If the flow of arterial blood only is arrested, the part depending upon it for nutrition becomes numb, cold and shrivelled, and the form of mortification known as dry gangrene occurs.
