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.
