Feline intrahepatic portosystemic shunt
Portosystemic shunts, or liver shunts, are abnormal vascular communications that result in varying degrees of illness. Surgery is currently considered the treatment of choice; however it is a risky procedure with a high complication rate even in the best hands. SEVS sponsored the first ever minimally invasive treatment in a cat.

Pablo was a 4 month old cat that was taken to a veterinarian because of severe lethargy and tremors.

Pablo was found to have a liver shunt. The surgery was considered very risky and therefore a catheter was used to block the shunt with coils.

Pablo made a fantastic recovery and is now leading a normal, playful and happy life...

Gadolinium venograms obtained following temporary balloon occlusion of the PSS in the cat in Figure 1—Blood no longer flows through the shunt vessel (arrowhead), but perfuses the liver. PV = Portal vein. Figure 2—Size and branching pattern of the intrahepatic portion of the portal vein appear to be normal. S = Shunt vessel. CM = Cranial mesenteric vein.

Figure 3—Ventrodorsal radiographic view of the abdomen of the cat in Figure 1 immediately after placement of 3 stainless steel coils to occlude the PSS.

Collapsing trachea
Tracheal collapse is a relatively common abnormality in small and toy breed dogs that is due to early loss of the supporting structures. Breathing can be so difficult as to become life threatening. When medical treatment fails, some animals may be candidates for surgery. However, surgical procedures can have significant complications. SEVS sponsored procedures involve the placement of a device that improves breathing without surgery.

This is the story of a dog with a collapsing airway that was treated using a stent donated by SEVS...
