Stomach imaging Flashcards
In what situations would you want to radiograph the oespophagus?
Label this radiograph
What contrast media can be used to view the oesophagus in action via radiography?
Barium sulphate paste
Liquid barium sulphate suspension
Oral aqueous iodine solutions
Fill in the table showing the location of gas and fluid in the stomach upon different radiograph views
Which radiograph view is this based on the location of gas in the stomach?
Dorso-ventral
What radiograph view is this based on the location of gas in the stomach?
Ventrodorsal - gas in corpus/pylorus region
What radiograph view is this based on the location of gas in the stomach?
Right lateral view - gas cap in fundus region
What radiograph view is this based on the location of gas in the stomach?
Left-lateral
Gas cap in pylorus region
How does gastric dilation and volvulus (GDV) occur?
Stomach enlarges/dilates due to food or gas
Stomach begins to rotate (pylorus travels ventrally)
Stomach twists
No gas or liquid can escape -> rupture
When does GDV often occur and in what breeds?
When a pet has eaten and then exercised afterwards
Common in big chested breeds - dobermans, labradors, mastiffs, daschund
How can GDV be treated?
Release gas via stomach tube
Surgically attach stomach to base of abdomen to prevent reoccurence
What other structures are affected in GDV?
- spleen is attached to greater curvature of stomach - spleen can rotate -> congestion and splenomegaly
- vena cava and portal vein can become compressed -> decreased venous return to heart
- dilated stomach presses on diaphragm which reduced thoracic space -> decreased tidal volume and shortness of breath
What is secondary peristalsis?
