1

What are the umbilical structures and what do they turn into

umbilical vein - round ligament of liver
umbilical arteries - round lig of the bladder
urachus - connects the bladder and allantois

2

whos at risk for acquired umbilical patent urachus?

debilitated foals
septicemic foals

3

Patent urachus can cause

septic arthritis
spetic physitis
septicemia

4

Clinical signs of a patent urachus

moisture around navel
drip or stream from umbilicus when posturing to urinate

5

Dx of Patent urachus

Clinical signs
positive contrast rads
ultrasound* - vesicourachal patency, umbilical or urachal abscess.

6

Tx of patent urachus

BS AM for up to 5 days. If nothing, surgerize

7

Indications for surgery

failure to respond to AM
rent in urachus that produces SQ swelling

8

Surgery procedure

dorsal recumbency
elliptical incision
dissect umbilicus and urachus from body wall
ligate the umbilical vein and cut,
ligate the umbilical arteries and cut (and part of the bladder too)
2-incision pattern to close bladder
lavage abdomen with saline
close up

9

post-op care for patent urachus

AM 3-5 days
stall rest for 2 weeks
remove sutures at 14 days

10

CLinical signs of Omphalophlebitis

overt signs of infection
high WBC and fibrinogen
joint infection, diarrhea, penumonia concurrently

11

Dx of Omphalophlebitis

careful palpation
US

12

how long can the vessels in urachal region be seen after birth?

umb vein - 2 months, but should be hypoechoic and

13

Tx of Omphalophlebitis

BS AM (for up to 2-3 weeks) --> esp chloramphenicol, but the notes say PenGent
re-evaluate every 5-7 days
surgerize

14

After care of Omphalophlebitis patients includes

monitoring for evidence of septicemia --> esp joints.
stall rest for 2 weeks

15

prognosis of Omphalophlebitis

if into liver, poor

16

Umbilical hernia reasons for forming

failure of umbilical stump to completely heal after birth
Attributed to:
- trauma during birth
-excessive straining
-umbilical cord infection

17

3 portions of the Umbilical hernia

1. the ring
2. the hernia sac
3. the contents of an abdominal hernia

18

Dx of Umbilical hernia

digital palpation - see ring size nature of contents,
DON'T LANCE UNTIL YOU KNOW

19

An Umbilical hernia is reducable if...

20

We go to surgery for Umbilical hernia when...

not spont heal in 4 months
greater than 10 cm in diameter
when there is incarceration
any increase in hernia size, firmness, edema, or pain on palpation

21

Hernia clamps are good right?

NO.

22

Surgery includes...

GA in dorsal recumbency
elliptical incision
expose rectal sheath of rectus abdom muscle
do the technique open or closed,
then simple continuous to close suture
regular closing

23

What is the open technique for Umbilical hernias?

the abdomen is entered. to get the guts in the right place that way.

24

What is the closed technique for Umbilical hernias?

the abdomen is not entered and the hernia is just inverted and sewn up

25

what are aftercare considerations compare to a castration?

stall confinemnet for a month to 1.5.
Castration is walk around so don't do both at the same time.
