Which of the following describes a hernia with a compromised blood supply that may lead to necrosis?

A strangulated hernia is characterized by a compromised blood supply to the incarcerated tissue, which can lead to necrosis if not addressed promptly. This occurs when the hernia becomes trapped and not only is it unable to be reduced back into the abdominal cavity, but the blood vessels supplying the affected tissue also become compressed. This lack of blood flow can cause the tissue to become ischemic, and if intervention is delayed, it can lead to necrosis, which is the death of the tissue.

In contrast, a reducible hernia can be pushed back into the abdomen without risk of compromising blood supply. An incarcerated hernia does involve a section of tissue that is trapped but does not necessarily imply compromised blood supply without the added factor of strangulation. A sliding hernia refers to one in which a portion of the organ forms part of the hernia sac, but again does not do so in a way that inherently compromises blood supply. Thus, the term that best describes the condition leading to potential necrosis due to a compromised blood supply is a strangulated hernia.
