Acute GDV
Life-threatening condition where you see:

* **Gastric Dilation:** Fluid and/or food accumulates in the stomach
* **Gastric Volvulus:** The stomach rotates along the mesenteric axis and obstruction of gastro-oesophageal and pyloric outflow
* **High Intragastric Pressure and Twisting**: causes outflow obstruction to gastric veins and more fluid and gas build up in stomach
* **Distended Stomach**: compresses the vena cava which decreases venous return and leads to cardiac failure
