OBJETIVOS: Realizou-se investiga\u00e7\u00e3o anat\u00f4mica da vasculariza\u00e7\u00e3o arterial do col\u00f3n sigm\u00f3ide para se obter um par\u00e2metro que possa ser aplicado a racioc\u00ednio t\u00e1tico nas opera\u00e7\u00f5es de abaixamento do c\u00f3lon sigm\u00f3ide ao per\u00edneo, ap\u00f3s a ressec\u00e7\u00e3o alargada do reto-\u00e2nus e seus esf\u00edncteres na neoplasia maligna retoanal. MATERIAL E M\u00c9TODOS: Analisou-se o mesoc\u00f3lon sigm\u00f3ide de 33 cad\u00e1veres formolizados, 22 do sexo masculino e 11 do feminino, atrav\u00e9s de dissec\u00e7\u00f5es destes com os intestinos in situ. Para isso, cateterizou-se a art\u00e9ria mesent\u00e9rica inferior, sendo esta contrastada com solu\u00e7\u00e3o de aguarr\u00e1s, thinner, l\u00e1tex de cor vermelha e policloreto de vinil. RESULTADOS: A art\u00e9ria mesent\u00e9rica inferior originou-se, na maioria dos casos, na face anterior esquerda da aorta abdominal, a uma dist\u00e2ncia m\u00e9dia de 4,3 cm do seu \u00e2ngulo inferior de bifurca\u00e7\u00e3o; a art\u00e9ria c\u00f3lica esquerda, em 25 cad\u00e1veres, originou-se diretamente da art\u00e9ria mesent\u00e9rica inferior. O n\u00famero de art\u00e9rias sigm\u00f3ideas variou de um a cinco. Verificou-se um plano arterial principal que iniciaria na ligadura da art\u00e9ria mesent\u00e9rica inferior, abaixo da origem da art\u00e9ria c\u00f3lica esquerda, sendo o sigm\u00f3ide abaixado ao per\u00edneo. CONCLUS\u00c3O: O conhecimento da vasculariza\u00e7\u00e3o do col\u00f3n sigm\u00f3ide e sua observa\u00e7\u00e3o no transoperat\u00f3rio poderiam orientar a t\u00e1tica e t\u00e9cnica cir\u00fargica na opera\u00e7\u00e3o de abaixamento c\u00f3lico ao per\u00edneo e colostomia perineal.<\/jats:p>","DOI":"10.1590\/s0004-28032003000400003","type":"journal-article","created":{"date-parts":[[2005,4,15]],"date-time":"2005-04-15T14:21:00Z","timestamp":1113574860000},"page":"209-215","source":"Crossref","is-referenced-by-count":5,"title":["Contribui\u00e7\u00e3o \u00e0 anatomia arterial do c\u00f3lon sigm\u00f3ide aplic\u00e1vel a opera\u00e7\u00f5es de abaixamento"],"prefix":"10.1590","volume":"40","author":[{"given":"S\u00e1vio Lana","family":"Siqueira","sequence":"first","affiliation":[{"name":"Faculdade de Ci\u00eancias M\u00e9dicas de Minas Gerais"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alcino","family":"L\u00e1zaro-da-Silva","sequence":"additional","affiliation":[{"name":"Universidade Federal de Minas Gerais"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"221","article-title":"Art\u00e8res de l'intestin grele et des colons","volume":"2","author":"Corsy F","year":"1913","journal-title":"Bibliographie Anatomique"},{"key":"ref2","first-page":"281","article-title":"Sur un d\u00e9tail de technique dans l'extirpation abdomino-p\u00e9rin\u00e9ale du rectum","volume":"12","author":"Cun\u00e9o B","year":"1914","journal-title":"J Chir (Paris)","ISSN":"http:\/\/id.crossref.org\/issn\/0021-7697","issn-type":"print"},{"key":"ref3","series-title":"Estudo an\u00e1tomo-cir\u00fargico das art\u00e9rias do colo sigm\u00f3ide e do segmento reto-sigm\u00f3ide","author":"Degni M","year":"1947"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"677","DOI":"10.1002\/bjs.1800010417","article-title":"The arterial supply of the rectum and pelvic colon","volume":"1","author":"Drummond H","year":"1913","journal-title":"Br J Surg","ISSN":"http:\/\/id.crossref.org\/issn\/0007-1323","issn-type":"print"},{"key":"ref5","series-title":"Contribui\u00e7\u00e3o ao estudo anat\u00f4mico das art\u00e9rias c\u00f3licas (arteriae colicae) e da irriga\u00e7\u00e3o das flexuras c\u00f3licas direita e esquerda (flexurae colicae dextra et sinistra)","author":"Esper FE","year":"1983"},{"key":"ref6","series-title":"Anatomia -
