This study investigated the long-term distribution of HV flow following two Fontan completion methods: HV-to-azygos vein shunt (HVAZ) and HV-to-pulmonary artery shunt (HVPA).\n                    <jats:bold>Methods:<\/jats:bold>\n                    We retrospectively reviewed 20 patients who underwent Fontan completion after the Kawashima procedure between 2004 and 2021 (HVAZ,\n                    <jats:italic toggle=\"yes\">n\u2009=\u2009<\/jats:italic>\n                    10; HVPA,\n                    <jats:italic toggle=\"yes\">n\u2009=\u2009<\/jats:italic>\n                    10). HV flow distribution was assessed by angiography (balanced\/partly unbalanced\/completely unilateral). For long-term analysis, patients were grouped according to final HV configuration, including those who required shunt conversion after initial Fontan completion. Group comparisons used Fisher's exact and Mann\u2013Whitney tests.\n                    <jats:bold>Results:<\/jats:bold>\n                    Balanced HV flow was observed in 7\/9 patients with HVAZ morphology compared with 1\/10 with HVPA (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.006). In the bilateral superior vena cava (SVC) subset, 6\/7 with HVAZ had balanced flow versus none with HVPA (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.005). Median follow-up was 9.2 years, during which final oxygen saturation (91% vs. 95%,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.39) and reintervention rates were comparable between groups, although the timing and underlying causes of reinterventions differed.\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    HVAZ was associated with more balanced HV flow than HVPA, including patients with bilateral SVCs. Long-term outcomes such as oxygen saturation were comparable, suggesting that HVAZ may represent a physiologically advantageous option for Fontan completion in patients with complex venous anatomy.\n                  <\/jats:p>","DOI":"10.1177\/21501351261432634","type":"journal-article","created":{"date-parts":[[2026,4,15]],"date-time":"2026-04-15T14:44:33Z","timestamp":1776264273000},"page":"766-775","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Balanced Hepatic Venous Flow with Hepatic to Azygos Vein Shunt Following the Kawashima Procedure"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7495-3694","authenticated-orcid":false,"given":"Yuchen","family":"Cao","sequence":"first","affiliation":[{"name":"Kanagawa Children's Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihide","family":"Asou","sequence":"additional","affiliation":[{"name":"Kanagawa Children's Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Tachibana","sequence":"additional","affiliation":[{"name":"Kanagawa Children's Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norihiko","family":"Shiiya","sequence":"additional","affiliation":[{"name":"NHO Hakodate Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuma","family":"Okamoto","sequence":"additional","affiliation":[{"name":"Hamamatsu University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,4,15]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(19)37445-8"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/2150135119842869"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezr003"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/2150135118809082"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2005.04.043"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2010.11.032"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2010.06.009"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(99)00494-4"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(02)00002-7"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(02)05019-1"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2010.08.088"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2015.02.049"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2010.06.114"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2022.10.015"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00380-020-01685-y"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/ejhf.1365"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2018.11.102"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezab478"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2019.12.024"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2008.06.043"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2016.03.019"},{"key":"e_1_3_3_23_2","article-title":"Hepatic-to-azygos vein redirection after a failed bifurcated graft Fontan conversion","volume":"36","author":"Koizumi J","year":"2023","unstructured":"Koizumi J, Ikai A, Iwase T, Kin H.
