Gastric Dilatation and Volvulus (GDV)
By Larissa Patterson,
Canine dilatation and volvulus, also known as bloat, is a serious life-threatening condition that is fatal if left untreated.
Gastric dilatation is when the stomach dilates and maintains its normal position. Dogs are usually able to relieve this pressure by vomiting or belching.
Gastric dilatation and volvulus is when the stomach dilates then rolls or twists, closing off openings leading in from the esophagus and out to the intestines, so the pylorus, or lower portion of the stomach, ends up lying alongside the left body wall.
If the stomach twists enough, the spleen and major blood vessels in the area twist as well. This can cause a loss of blood flow to the stomach and other abdominal organs causing tissue damage.
Right lateral is the best view to confirm GDV, the pylorus is displaced cranially and dorsally to the fundus. The stomach rarely turns in a counter-clockwise direction.
There are many theories on how to prevent GDV, however, they are just theories.One thing that dog owners of high-risk breeds should consider is prophylactic gastroplexy, which involves tacking the stomach to the body wall.
