A previous evidence-based review (2012) found low quality of evidence for papers assessing the treatment of cEHPSS in dogs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To assess the quality of evidence available in the treatment of cEHPSS, summarize the current state of knowledge with respect to outcome after cEHPSS management, and compare different treatment techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Animals<\/jats:title>\n                    <jats:p>Not used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A bibliographic search was performed without date or language restrictions. Studies were assessed for quality of evidence (study design, study group sizes, subject enrollment quality, and overall risk of bias) and outcome measures reported (perioperative outcome, clinical outcome, and surgical or interventional outcome), all reported with 95% confidence intervals. A network meta-analysis was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Forty-eight studies were included. Six retrospective studies (grade 4b) compared 2 techniques and 7 were abstracts (grade 5). The quality of evidence was low and risk of bias high. Regarding surgical outcome, statistically significant superiority of ameroid constrictor over thin film band was observed (P = .003).

Ameroid is superior to thin film band in causing EHPSS closure. Blinded randomized studies comparing different treatment modalities, which routinely include postoperative imaging to assess cEHPSS closure and acquired portosystemic shunt development are essential.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jvim.15607","type":"journal-article","created":{"date-parts":[[2019,8,31]],"date-time":"2019-08-31T06:04:48Z","timestamp":1567231488000},"page":"1865-1879","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Treatment of congenital extrahepatic portosystemic shunts in dogs: A systematic review and meta-analysis"],"prefix":"10.1093","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0138-4064","authenticated-orcid":false,"given":"Gon\u00e7alo","family":"Serrano","sequence":"first","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6964-6307","authenticated-orcid":false,"given":"Marios","family":"Charalambous","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nausikaa","family":"Devriendt","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hilde","family":"de Rooster","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Femke","family":"Mortier","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Paepe","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Ghent University Small Animal Department, , Ghent,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,9,1]]},"reference":[{"key":"2026020922094715900_jvim15607-bib-0001","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1111\/j.1748-5827.1976.tb06577.x","article-title":"Four cases of congenital portacaval shunt in the dog","volume":"17","author":"Barrett","year":"1976","journal-title":"J Small Anim Pract"},{"key":"2026020922094715900_jvim15607-bib-0002","doi-asserted-by":"crossref","first-page":"531","DOI":"10.1111\/j.1751-0813.1998.tb10208.x","article-title":"Cellophane banding for the gradual attenuation of single extrahepatic portosystemic shunts in eleven dogs","volume":"76","author":"Youmans","year":"1998","journal-title":"Aust Vet J"},{"key":"2026020922094715900_jvim15607-bib-0003","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1111\/j.1748-5827.1998.tb03595.x","article-title":"Medical management of congenital portosystemic shunts in 27 dogs\u2013a retrospective study","volume":"39","author":"Watson","year":"1998","journal-title":"J Small Anim Pract"},{"key":"2026020922094715900_jvim15607-bib-0004","doi-asserted-by":"crossref","first-page":"495","DOI":"10.1111\/j.1532-950X.1996.tb01449.x","article-title":"Gradual occlusion of extrahepatic portosystemic shunts in dogs and cats using the ameroid constrictor","volume":"25","author":"Vogt","year":"1996","journal-title":"Vet Surg"},{"key":"2026020922094715900_jvim15607-bib-0005","doi-asserted-by":"crossref","first-page":"1048","DOI":"10.1111\/j.1939-1676.2010.0565.x","article-title":"Intravascular occlusion for the correction of extrahepatic portosystemic shunts in dogs","volume":"24","author":"Hogan","year":"2010","journal-title":"J Vet Intern Med"},{"key":"2026020922094715900_jvim15607-bib-0006","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1111\/j.1748-5827.2011.01144.x","article-title":"Treatment of extrahepatic congenital portosystemic shunts in dogs -
