  1. Gastric Dilatation and Volvulus (GDV) By Larissa Patterson, June 2010

  2. GDV 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.

  3. GDV 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.

  4. Common breeds • GDV is commonly seen in older, large, deep-chested dogs such as: • German Shepherds • Standard Poodles • Weimareiners • St. Bernards • Great Danes • However it has been reported in cats, guinea pigs and primates

  5. Theories • Dogs over 7 years old • Males are twice as likely as females • Dogs that tend to be more nervous, anxious, or fearful • Dogs that are fed once a day, are at a higher risk than those fed twice a day • Dogs that inhale their food to quickly • Dogs that exercise soon after eating

  6. 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.

  7. prevention 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.
