The shunts were initially categorized by the Parks classification and were followed by serial ultrasounds. Clinical presentation, clinical course, laboratory data, shunt ratios, and time to shunt closure were all followed on subsequent ultrasounds. The most common type of CPPS was the Type 3 shunt. In cases where shunt ratios were measured, the shunt ratio gradually decreased in tandem with decreasing ammonia levels until spontaneous closure was achieved. Predictors of lack of shunt closure included high shunt ratios and Type 4 shunts. Patients with CPPS can be followed with the shunt ratio calculation obtained from sonographic imaging, which may correlate to ammonia levels and indicate risk of hepatic encephalopathy as well as predict speed and timing of closure.</p>","PeriodicalId":51528,"journal":{"name":"Journal of Ultrasound","volume":" ","pages":"227-238"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11947343/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141162767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
