Abstract

<abstract abstract-type="main" id="jvim12188-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="jvim12188-sec-0001" sec-type="section"> <title>Background</title> <p>Portosystemic shunts are uncommonly reported in cats. The majority of reports describe congenital shunts in young cats originating from the left gastric vein. Although they are only rarely reported, acquired portosystemic shunts in cats appear to be more variable in their anatomic location.</p> </sec> <sec id="jvim12188-sec-0002" sec-type="section"> <title>Hypothesis/Objective</title> <p>To describe the signalment and disease conditions found in cats with splenosystemic shunts.</p> </sec> <sec id="jvim12188-sec-0003" sec-type="section"> <title>Animals</title> <p>Thirty‐three client‐owned cats with documented splenosystemic shunts.</p> </sec> <sec id="jvim12188-sec-0004" sec-type="section"> <title>Materials and Methods</title> <p>Retrospective study. All cats with vascular communications between the splenic and left renal veins or the splenic vein and caudal vena cava diagnosed ultrasonographically between 2004 and 2011 were included. Collected data included age, breed, sex, presenting complaints, clinicopathologic data, as well as clinical diagnosis when available.</p> </sec> <sec id="jvim12188-sec-0005" sec-type="section"> <title>Results</title> <p>Splenosystemic shunts were identified in 1.3% of the cats that had an abdominal ultrasound performed during the study period. Older, spayed female cats were found to be significantly overrepresented when compared with the total population of cats having undergone ultrasound over the same time period. A large proportion of cats (42%) had a hepatopathy with the potential for associated portal hypertension.</p> </sec> <sec id="jvim12188-sec-0006" sec-type="section"> <title>Conclusions and Clinical Importance</title> <p>Neither the signalment of cats in this report nor the anatomy of their portovascular anomalies shared similarities with those cats previously identified with single‐vessel shunts. The relevance and etiology of these newly described splenosystemic shunts remain elusive and warrantsfurther investigation.</p> </sec> </abstract>
