Plain-English summary
A group of 124 dogs with a congenital liver condition called extrahepatic portosystemic shunt (CEPSS) underwent surgery to correct the issue, with some having a special imaging test called computed tomography angiography (CTA) beforehand. The study found that using CTA did not increase the risk of complications or affect the length of surgery compared to dogs that did not have the test. Overall, the dogs that had surgery, whether they had the CTA or not, had similar outcomes and recovery rates. This suggests that preoperative CTA is a safe option for diagnosing and planning surgery for this condition in dogs.

Abstract
This study evaluated the safety of preoperative computed tomography angiography (CTA) and its effect on surgical time and clinical outcomes in dogs that underwent surgical correction of a single congenital extrahepatic portosystemic shunt (CEPSS). Patient data were retrospectively collected from medical records and owner communications for 124 dogs with single CEPSS, undergoing preoperative CTA (n = 43) or not (n = 81) which were surgically treated from 2005 to 2014. The frequency of major postoperative complications was 4.7% and 9.9% for the CTA and no CTA groups, respectively (P = 0.49). Mean ± standard deviation (SD) surgical time for the preoperative CTA group was 84 ± 40 min and 81 ± 31 min for the no CTA group (P = 0.28). We conclude that anesthetized preoperative CTA appears to be a safe method for diagnosis and surgical planning in dogs with single CEPSS, and does not appear to affect surgical procedure time, complication rate, or clinical outcome.
