Research output: Contribution to journalArticlepeer-review


Helical computed tomographic (CT) angiography was performed in 16 dogs with known or suspected porto-systemic shunts. Fifteen portosystemic shunts were detected including five single intrahepatic shunts. five single extrahepatic shunts, and five multiple extrahepatic shunts. One dog had a normal CT examination. All diagnoses were confirmed by one or several alternate methods including ultrasound. surgery. necropsy, angiography, and liver biopsy. CT detected the origin of 13 of 15 portosystemic shunts and insertion of 13 of 15 shunts. Limitations included inability to resolve two vessels originating verv close to each other. and identification of vessels that traveled parallel to the axial image plane. CT angiography is a proimsing, minimally invasive method of diagnosing a variety of portosystemic shunts in dogs.
