The goal of this retrospective, multi\u2010institutional study was to use CT angiography to create an anatomical\u2010based nomenclature system for canine congenital EHPSS. These shunt morphologies were then evaluated to identify any significant association with patient age, sex, breed, weight, or subjective portal perfusion score. Data collected respectively from the SVSTS and VIRIES list\u2010serves included patient DOB, sex, breed, weight, CT date, and reported diagnosis. A single author (C.W.) viewed all CT scans and classified shunts based on the shunt portal vessel(s) of origin, the shunt systemic vessel(s) of insertion, and any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between one (poor\/none) and five (good\/normal) based on the caliber of the intrahepatic portal veins. A total of 1182 CT scans were submitted from 13 different institutions. Due to exclusion criteria, 100 (8.5%) were removed, leaving 1082 CT scans to be included. Forty\u2010five different EHPSS anatomies were identified with five classifications accounting for 85% of all shunts (left gastric\u2010phrenic [27%], left gastric\u2010azygos [19%], left gastric\u2010caval [15%], aberrant left gastric\u2010caval with right gastric vein [12%], and aberrant left gastric\u2010caval with right gastric vein and short gastric vein [11%]). Shunt origin involved the left gastric vein in 95% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of the CT scan (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001), sex (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.009), breed (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001), weight (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001), and subjective portal perfusion score (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001). An anatomical classification system for canine EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for these patients.<\/jats:p>","DOI":"10.1111\/vru.13415","type":"journal-article","created":{"date-parts":[[2024,8,5]],"date-time":"2024-08-05T17:31:38Z","timestamp":1722879098000},"page":"702-712","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Anatomical classification of canine congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi\u2010institutional study in 1082 dogs"],"prefix":"10.1111","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5202-9962","authenticated-orcid":false,"given":"Chick","family":"Weisse","sequence":"first","affiliation":[{"name":"Animal Medical Center  New York New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William Alexander","family":"Fox\u2010Alvarez","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine University of Florida  Gainesville Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federico R Vilaplana","family":"Grosso","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine University of Florida  Gainesville Florida USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0099-7974","authenticated-orcid":false,"given":"Kazushi","family":"Asano","sequence":"additional","affiliation":[{"name":"Nihon University  Fujisawa Kanagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kumiko","family":"Ishigaki","sequence":"additional","affiliation":[{"name":"Nihon University  Fujisawa Kanagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8982-2558","authenticated-orcid":false,"given":"Allison L","family":"Zwingenberger","sequence":"additional","affiliation":[{"name":"Davis School of Veterinary Medicine University of California  Davis California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth A","family":"Carroll","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine North Carolina State University  Raleigh North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5011-9005","authenticated-orcid":false,"given":"Valery F","family":"Scharf","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine North Carolina State University  Raleigh North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Lipscomb","sequence":"additional","affiliation":[{"name":"Royal Veterinary College  Hatfield Hertfordshire England"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mandy L","family":"Wallace","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine University of Georgia  Athens Georgia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Aly","sequence":"additional","affiliation":[{"name":"Cornell University College of Veterinary Medicine  Ithaca New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beth","family":"Biscoe","sequence":"additional","affiliation":[{"name":"Animal Imaging  Irving Texas USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacqueline R","family":"Davidson","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine &amp;
