ventrally & left (clockwise)
51
Which direction does the fundus typically rotate in a GDV?
to the right
52
What happens to the spleen during GDV?
The spleen is displaced in the direction of the stomach to the right dorsal due to the gastrosplenic ligament
53

54
What type of shock does GDV cause?
obstructive however it can cause the other ones!

In an incisional gastropexy, an adhesion should be formed between which two GI regions?
pyloric antrum & right body wall [just behind last rib]
83
If a gastrostomy tube is being placed for GDV gastropexy, where should it be placed? What if it is being placed as a stomach tube for feeding?
gastropexy for GDV: tube in pylorus stomach tube for feeding: tube in fundus
84
What are the steps for a tube gastrostomy for a GDV?
pull tube through right body wall place purse string around the area of stomach we want to incise feed tube into gastric lumen tie purse string place pexy sutures secure externally with finger trap suture
