DI Flashcards
Give the three differentials for the head of the spleen not being visible on a dog Abdo VD.
- Poor serosal detail
- Splenectomy
- Splenic torsion.
Why is it abnormal to see the tail of the spleen on a cat Abdo VD?
Because their spleen is so small it doesn’t reach all the way around.
If it can be viewed = splenomegaly due to neoplasia until proven otherwise.
Where is WNL for the tail of the spleen to be located in dog Abdo Lateral rads?
Anywhere from the bladder to the base of the pylorus.
What are the two most common causes of splenomegaly in cats?
Mast cell tumour
Lymphoma
What is the normal size of a dog stomach on lateral rad?
3 intercostal spaces wide and pylorus should be half this.
As a general rule is a fluid-filled stomach acute of chronic?
Chronic.
A gas filled stomach is acute.
As a general rule.
Where is the normal location of the duodenum on lateral and vd radiographs?
Lateral: comes out of the stomach half-way between the fundus and pylorus. Runs parallel with the ventral wall.
VD: runs down the right hand side.
Is it normal to see the duodenum?
No
Where is the normal location of the caecum?
Lateral: ventral to L3 in the mid abdo
VD: to the right of L3.
If the small intestine is > 1.7 x the height of L5 vertebrae on a lateral radiograph, what is this an indication of?
> 2x = 80% chance there is a small intestine obstruction.
What grade is a ‘barley audible’ heart grade murmur?
Grade 1
What is a Grade 2 Heart Murmur described as?
A readily audible soft murmur.
Describe a Grade 3 Heart Murmur.
Moderate intensity murmur, usu. auscultated over more than one valve.
What Grade Heart Murmur is this?
Loud murmur with a precordial thrill, usually radiates to both sides of the chest.
Grade IV
Describe a Grade VI Heart Murmur.
Loud murmur with a precordial thrill and still audible with the stethoscope off the chest wall.
