Within a year after transplant she presented with prehepatic portal hypertension, that was treated with MRB using a deceased donor ABO compatible iliac vein as conduit. Six months later, she was taken to the operating room for bypass revision, during the procedure the MRB showed no flow and no thrombus, and a large splenorenal collateral vein that was causing a portal perfusion steal phenomenon was observed. After dissecting the collateral vein, an 8 cm x8 mm segment of this vessel was used as an autologous conduit to re-do the Rex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Failed of MRB can be attributed to portal steal phenomenon, hypercoagulable disorders, bypass contraction or kinking. In this case we believe the culprit to be the former. When there is a history of longstanding portal hypertension, large collaterals develop; thus, intraoperative portal vein flow measurement is critical and ligation of large collaterals during liver transplantation and MRB should be performed to avoid portal steal phenomenon postprocedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Using a collateral vein as an alternative autologous venous conduit is a feasible option that can have durable success.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2019.05.051","type":"journal-article","created":{"date-parts":[[2019,6,3]],"date-time":"2019-06-03T22:36:01Z","timestamp":1559601361000},"page":"230-233","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Revision of meso-Rex bypass utilizing a collateral vein in a patient with portal steal phenomenon after liver transplant"],"prefix":"10.1097","volume":"60","author":[{"given":"Ruben","family":"Blachman-Braun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fidel","family":"Lopez-Verdugo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diane","family":"Alonso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda","family":"Book","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter G.","family":"Feola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel I.","family":"Rodriguez-Davalos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-58-20260114","doi-asserted-by":"crossref","first-page":"1749","DOI":"10.1016\/S0140-6736(14)60121-5","article-title":"Liver cirrhosis","volume":"383","author":"Tsochatzis","year":"2014","journal-title":"Lancet"},{"key":"R2-58-20260114","doi-asserted-by":"crossref","first-page":"426","DOI":"10.1111\/j.1399-3046.2012.01652.x","article-title":"Portal hypertension in children: expert pediatric opinion on the report of the Baveno V Consensus Workshop on Methodology of Diagnosis and Therapy in Portal Hypertension","volume":"16","author":"Shneider","year":"2012","journal-title":"Pediatr.
