Balloon occlusion of the caudal vena cava for vascular contrast studies as an aid to intravascular coil embolisation for the treatment of intrahepatic portosystemic shunts in three dogs.

Abstract

CASE REPORT: Three dogs were treated with fluoroscopically guided coil embolisation of intrahepatic portosystemic shunts. A large-diameter vascular occlusion balloon was used to improve the vascular contrast studies required to perform this procedure. This technique improved identification of vascular structures and allowed completion of the procedures without the need for digital subtraction angiography. CLINICAL SIGNIFICANCE: Interventional radiological procedures are an emerging area of veterinary medicine and procedural modifications may help expand their use in clinical practice.
