ventral hernia

ven·tral her·ni·a

an abdominal incisional hernia.

ventral hernia

abdominal hernia

A protrusion of loops of intestine, fat, or fibrous tissue through a defect or weakened region of the abdominal wall—e.g., an umbilical hernia.

ventral hernia

Abdominal bernia, see there.

ventral hernia

A HERNIA through the abdominal wall but not through the commoner UMBILICAL, INGUINAL or FEMORAL routes.


the abnormal protrusion of part of an organ or tissue through the structures normally containing it.
In this condition, a weak spot or other abnormal opening in a body wall permits part of the organ to bulge through. A hernia may develop in various parts of the body; most commonly in the region of the abdomen.
A layman's term for hernia is rupture. A hernia is either acquired or congenital.
Anatomically specific hernias are listed under their individual sites.

caudal abdominal h's
see inguinal, femoral, scrotal hernias (below).
cerebral hernia
see brain herniation.
cord hernia
a type of umbilical hernia in which the midgut has failed to return to the abdominal cavity during fetal development and remains within the umbilical cord.
crural hernia
femoral hernia.
external hernia
protrusion of abdominal contents through an opening in the abdominal wall.
false hernia
a structural defect with contents but without a peritoneal sac.
fat hernia
hernial protrusion of peritoneal fat through the abdominal wall or through the vulvar wall during a difficult calving.
incarcerated hernia
hernia so occluded that it cannot be returned by manipulation; it may or may not become strangulated.
incisional hernia
hernia after operation at the site of the surgical incision, owing to improper healing or to excessive strain on the healing tissue; such strain may be caused by excessive muscular effort, activity, or by obesity, which creates additional pressure on the weakened area.
inguinoscrotal hernia
see scrotal hernia (below).
irreducible hernia
incarcerated hernia.
mesenteric hernia
hernia of a loop of small intestine through a traumatic tear in the mesentery.
muscle hernia
the belly of the muscle protrudes through a tear in the fascia and epimysium.
paraesophageal hernia
hiatal hernia in which part or almost all of the stomach protrudes through the hiatus into the thorax to the left of the esophagus, with the gastroesophageal junction remaining in place.
pelvic hernia
hernia caused by a loop of intestine becoming incarcerated in a hiatus between the wall of the pelvis and the ductus deferens, caused by tearing of the fold of the ductus at castration. May occur many months after the castration operation. Can be resolved, if diagnosed early enough, by traction on the taut mesentery per rectum.
pericardial hernia
perineal hernia
see perineal hernia.
pleuroperitoneal hernia
see diaphragmatic hernia.
prepubic hernia
the result of avulsion of the cranial pubic tendon.
reducible hernia
one that can be returned by manipulation.
scrotal hernia
inguinal hernia which has passed into the scrotum. When these become strangulated they cause severe abdominal pain and acute local swelling. In large animals the tightened spermatic cord can be felt disappearing into the inguinal canal. See also intestinal obstruction.

sliding hiatal hernia
hiatal hernia in which the stomach and the cardioesophageal junction protrude into the caudal mediastinum; the protrusion, which may be fixed or intermittent, is partially covered by a peritoneal sac.
slip hernia, slipped hernia
sliding hernia.
strangulated hernia
one that is tightly constricted. As any hernia progresses and bulges out through the weak point in its containing wall, the opening in the wall tends to close behind it, forming a narrow neck. If this neck is pinched tight enough to cut off the venous return, the hernia will quickly swell and become strangulated. This is a very dangerous condition that can appear suddenly and requires immediate surgical attention. Unless the blood supply is restored promptly, gangrene can set in and may cause death.
traumatic hernia
protrusion of abdominal viscera into a subcutaneous site because of traumatic injury to the abdominal muscles.
uterine hernia
a gravid uterus can prolapse through an inguinal hernia in dogs and cats.
vaginal hernia
hernia into the vagina; called also colpocele.
ventral hernia
trauma with tearing of the body wall results in prolapse of abdominal contents into the subcutaneous tissue. Also reported in ewes from violent straining during parturition.
