2.3.1 Clinical Presentation
An 8-day-old Percheron filly was presented for evaluation of a wet
umbilicus. The foal was bright, alert and afebrile with normal vital
parameters. The umbilicus was wet and subjectively enlarged on
palpation.
Ultrasonographic evaluation displayed moderate enlargement of the
umbilical vein and left umbilical artery. Portions of the umbilical
tissue appeared hyperechoic, but no acoustic shadowing was noted. A
pre-operative complete blood count revealed hyperfibrinogenemia (700
mg/dL; reference range: 300-500 mg/dL) with no other significant
findings.
