Gastric dilatation-volvulus (GDV) is a syndrome characterized by rapid accumulation of gas or food in the stomach, increased intragastric pressure and wall tension, and rotation of the stomach about its long axis. Gastric dis-tention unleashes a series of potentially lethal pathophysiologic events, the most important of which are compression of the portal and caudal vena caval venous blood flow, gastric necrosis, tissue aci-dosis, cardiac arrhythmia, disseminated intravascular coagulation, and hypoten-sive and cardiogenic shock. For dogs that develop GDV, surgical correction is strongly recommended. Among those dogs, mortality remains high (15% to 33%), even with aggressive resuscitative management.
