== Introduction ==
This condition is an acquired or congenital obstruction to the caudal vena cava affecting venous return to the right side of the heart. The venous obstruction causes increased pressure within the liver allowing for fluid and protein to leak out of the hepatic sinusoids into the surrounding areas.
== Signalment ==
'''Dogs:''' Young dogs under two years old; Male>Female
'''Dogs:''' Young dogs under two years old; male > female. There have been no reported cases in cats.
== Clinical Signs ==
Clinical signs can be vague and similar to other disease but include ascites (with modified transudate), hepatomegaly, lethargy, abdominal distension and abdominal pain and anorexia.
== Diagnosis ==
'''Blood tests''' may reveal elevated liver enzymes and the presence of a [[Stress Leukogram|stress leukogram]]. If ascites is present, examination of this will prove it to be a [[Modified Transudate|modified transudate]]. '''Radiography''' will show the presence of ascites and an enlarged Caudal Vena Cava. If an '''electrocardiograph''' (ECG) is performed, this may demonstrate right atrial enlargement (tall P waves). '''Echocardiography''' may show an obstruction. '''Abdominal ultrasound''' will also demonstrate ascites, plus hepatomegaly and enlarged hepatic veins. Angiography can be used to visualise blood flow.
== Treatment ==
Surgery is indicated for some cases, but is very risky. Medical treatment to provide supportive therapy, includes regular abdominocentesis, plus the use of drugs, furosemide (a diuretic) and enalapril, an ACE inhibitor.
=====Laboratory Findings=====
== Prognosis ==
Excellent with an experienced surgeon, but poor if only medical therapy is used.
