Reports primarily including western European populations have recently shed light regarding the pathophysiology, risk factors, natural history, treatment, and prognosis of this entity. Underlying predisposing conditions are documented in ~70% of cases, encompassing local risk factors, inherited and acquired thrombophilia, cancer, and systemic inflammatory conditions. Non-cirrhotic portal vein thrombosis can cause significant portal hypertension in the acute setting, but, more frequently, significant portal hypertension-related complications arise when the condition becomes chronic and portosystemic collaterals develop, increasing the risk for variceal bleeding and ascites. The diagnostic approach to screen for underlying thrombophilia remains a challenge, and recommendations in this regard, although scarce and backed by scarce evidence, have changed notably in the last years, leaning toward a universal screen in patients who develop this condition without a clear provoking factor. Recently, studies have shown that long-term anticoagulation may be appropriate even in the absence of clear provoking factors or underlying thrombophilia. Future studies should address which patients may benefit from this approach, which patients may not need it, and what the most appropriate strategies are to approach patients who do not recover portal vein patency with anticoagulation to further prevent portal hypertension-related complications.<\/jats:p>","DOI":"10.3390\/diagnostics15060721","type":"journal-article","created":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T12:06:59Z","timestamp":1741867619000},"page":"721","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Portal Vein Thrombosis in Patients Without Cirrhosis: Current Practical Approaches and Treatment Strategies"],"prefix":"10.3390","volume":"15","author":[{"given":"Fernando","family":"Gil-Lopez","sequence":"first","affiliation":[{"name":"Department of Liver Transplant, Mayo Clinic Florida, Jacksonville, FL 32224, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2305-9638","authenticated-orcid":false,"given":"Fausto Alfredo","family":"Rios-Olais","sequence":"additional","affiliation":[{"name":"Hematology and Oncology Department, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Tlalpan, Mexico City C.P. 14080, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia A.","family":"Mercado","sequence":"additional","affiliation":[{"name":"Department of Liver Transplant, Mayo Clinic Florida, Jacksonville, FL 32224, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denise M.","family":"Harnois","sequence":"additional","affiliation":[{"name":"Department of Liver Transplant, Mayo Clinic Florida, Jacksonville, FL 32224, USA"},{"name":"Department of Gastroenterology and Hepatology, Mayo Clinic Florida, Jacksonville, FL 32224, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"959","DOI":"10.1016\/j.jhep.2021.12.022","article-title":"Baveno VII-Renewing consensus in portal hypertension","volume":"76","author":"Bosch","year":"2022","journal-title":"J.
