Hello,

I need Your help please in this case. I have never seen such vascular malformation before.

The cat is a maine coon- 8 month old cat with severe ascites, pleural effusion, and mild pericardial effusion.

The effusion contains only lymphocytes-and is a milky modified transsudatum ( lymph). Blood work wnl.

There is no tricuspid regurgitation- the left side of the heart looks normal, the right side is a bit dilatated. I can’t see the diaphragm on the right side ( just the pericardium separates the liver from the heart)

I can see a huge v. cava, and severly dilatated hepatic veins-they form in the ventral liver lobe huge veinic plexus-where the blood flows slowly and turbulent flow is present.

The cat is now on furosemide and clopridogrel- doing better.

What kind of malformation is this? What would be the prognosis? What kind of treatement should we follow?

Thank You,

Rita
