This study analyzes the perioperative complications and survival of liver transplant patients with portal vein thrombosis (PVT). A retrospective observational cohort study of liver transplant patients was conducted. The outcomes were early mortality (30 days) and patient survival. A total of 201 liver transplant patients were identified and 34 (17%) patients with PVT were found. The most frequent extension of thrombosis was Yerdel 1 (58.8%), and a portosystemic shunt was identified in 23 (68%) patients. Eleven patients (33%) presented any early vascular complication, PVT being the most frequent (12%). The multivariate regression analysis showed a statistically significant association between PVT and early complications (OR = 3.3, 95% confidence interval 1.4\u20137.7; p = 0.006). Moreover, early mortality was observed in eight patients (24%), of which two (5.9%) presented Yerdel 2. For Yerdel 1, patient survival according to the extent of thrombosis was 75% at 1 year and 3 years, while for Yerdel 2, it was 65% at 1 year, and 50% at 3 years (p = 0.04). Portal vein thrombosis significantly influenced early vascular complications. Furthermore, portal vein thrombosis Yerdel 2 or higher impacts the survival of liver grafts in the short and long term.<\/jats:p>","DOI":"10.3390\/jcm12123951","type":"journal-article","created":{"date-parts":[[2023,6,9]],"date-time":"2023-06-09T08:37:33Z","timestamp":1686299853000},"page":"3951","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Portal Vein Thrombosis in Liver Transplantation: A Retrospective Cohort Study"],"prefix":"10.3390","volume":"12","author":[{"given":"Luis Manuel","family":"Barrera-Lozano","sequence":"first","affiliation":[{"name":"Transplant Department, Hospital San Vicente Fundaci\u00f3n, Rionegro 054047, Colombia"},{"name":"Vascular Medicine Department, Faculty of Medicine, Universidad de Antioquia UdeA, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaime Alberto","family":"Ram\u00edrez-Arbel\u00e1ez","sequence":"additional","affiliation":[{"name":"Transplant Department, Hospital San Vicente Fundaci\u00f3n, Rionegro 054047, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian Leonardo","family":"Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Transplant Department, Hospital San Vicente Fundaci\u00f3n, Rionegro 054047, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge Andr\u00e9s","family":"Becerra","sequence":"additional","affiliation":[{"name":"Foscal Clinic, Floridablanca 681003, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis Guillermo","family":"Toro","sequence":"additional","affiliation":[{"name":"Transplant Department, Hospital San Vicente Fundaci\u00f3n, Rionegro 054047, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3663-1416","authenticated-orcid":false,"given":"Carlos M.","family":"Ardila","sequence":"additional","affiliation":[{"name":"Basic Studies Department, School of Dentistry, Universidad de Antioquia UdeA, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1016\/j.ijsu.2020.04.068","article-title":"Current management of portal vein thrombosis in liver transplantation","volume":"82","author":"Bhangui","year":"2020","journal-title":"Int.
