Objetivos - Estudar detalhadamente a distribui\u00e7\u00e3o arterial em sua por\u00e7\u00e3o extra e intra-hep\u00e1tica e suas implica\u00e7\u00f5es na sec\u00e7\u00e3o regrada do f\u00edgado em dois segmentos anatomicamente equivalentes (lobo esquerdo e lobo direito). Material e M\u00e9todos - Estudo de 60 f\u00edgados provenientes de cad\u00e1ver fresco, examinando a art\u00e9ria hep\u00e1tica e suas ramifica\u00e7\u00f5es, bem como suas varia\u00e7\u00f5es anat\u00f4micas. A sec\u00e7\u00e3o hep\u00e1tica foi realizada em duas metades: lobo direito e esquerdo. Resultados - O peso total do f\u00edgado foi de 1536 \u00b1 361,8 g, do lobo direito 890,3 \u00b1 230,9 g e do esquerdo 649,3 \u00b1 172,6 g. Em 1 (1,6%) caso, o tronco hep\u00e1tico comum, era proveniente da art\u00e9ria mesent\u00e9rica superior, e em outro (1,6%), a art\u00e9ria hep\u00e1tica esquerda era proveniente da aorta abdominal. A art\u00e9ria hep\u00e1tica direita era proveniente do tronco cel\u00edaco em 44 (73,3%) casos, em 15 (25%) era oriunda da art\u00e9ria mesent\u00e9rica superior, sendo que em 11 (18,3%) casos era acess\u00f3ria e em 4(6,6%) era dominante. A art\u00e9ria hep\u00e1tica esquerda era acess\u00f3ria da art\u00e9ria g\u00e1strica esquerda em 2 (3,3%) casos. Em 9 (15%) casos houve trifurca\u00e7\u00e3o da art\u00e9ria hep\u00e1tica pr\u00f3pria, originando a art\u00e9ria hep\u00e1tica m\u00e9dia, que ficou assim distribu\u00edda: 6 (10%) casos como tronco \u00fanico para o segmento IV, em 2 (3,3%) casos para o segmento III e 1 (1,6%) para o segmento II. Em 2 (3,3%) casos, ocorreram 2 art\u00e9rias hep\u00e1ticas m\u00e9dias que irrigavam o segmento IV. Conclus\u00e3o - As varia\u00e7\u00f5es anat\u00f4micas da art\u00e9ria hep\u00e1tica n\u00e3o impediram a sec\u00e7\u00e3o do par\u00eanquima hep\u00e1tico em lobo direito e esquerdo.<\/jats:p>","DOI":"10.1590\/s0004-28032002000200003","type":"journal-article","created":{"date-parts":[[2005,4,15]],"date-time":"2005-04-15T14:19:44Z","timestamp":1113574784000},"page":"81-85","source":"Crossref","is-referenced-by-count":7,"title":["Varia\u00e7\u00f5es do sistema arterial hep\u00e1tico e sua aplicabilidade na biparti\u00e7\u00e3o do f\u00edgado: estudo anat\u00f4mico em cad\u00e1veres"],"prefix":"10.1590","volume":"39","author":[{"given":"Pedro Luiz","family":"BERTEVELLO","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eleazar","family":"CHAIB","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"737","DOI":"10.1097\/00000658-199612000-00009","article-title":"Split-liver transplantation: The Paul Brousse Policy","volume":"224","author":"Azoulay D","year":"1996","journal-title":"Ann Surg","ISSN":"http:\/\/id.crossref.org\/issn\/0003-4932","issn-type":"print"},{"key":"ref2","first-page":"367","article-title":"Reduced-size orthotopic liver graft in hepatic transplantation in children","volume":"95","author":"Bismuth H","year":"1984","journal-title":"Surgery","ISSN":"http:\/\/id.crossref.org\/issn\/0039-6060","issn-type":"print"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"403","DOI":"10.1097\/00007890-198902000-00048","article-title":"Hepatic reconstruction during liver transplantation","volume":"47","author":"Brems JJ","year":"1989","journal-title":"Transplantation","ISSN":"http:\/\/id.crossref.org\/issn\/0041-1337","issn-type":"print"},{"key":"ref4","series-title":"Chirurgisches Forum '84.
