M\u00c9TODOS: doze pacientes foram submetidas \u00e0 emboliza\u00e7\u00e3o de miomas uterinos com part\u00edculas de PVA-PVAc. Tr\u00eas a nove meses depois, realizou-se uma laparotomia com miomectomia. Analisaram-se os seguintes par\u00e2metros: volume do \u00fatero e do maior mioma; concentra\u00e7\u00f5es do horm\u00f4nio fol\u00edculo estimulante e de hemoglobina; sangramento menstrual (n\u00famero de dias e de absorventes utilizados), sinais e sintomas antes do tratamento, ap\u00f3s a emboliza\u00e7\u00e3o e ap\u00f3s a miomectomia. RESULTADOS: a m\u00e9dia de idade foi 37 anos e a m\u00e9dia do volume uterino, previamente ao tratamento, de 939,3cc. Tr\u00eas anos ap\u00f3s a emboliza\u00e7\u00e3o, observou-se diminui\u00e7\u00e3o do volume uterino (p=0,0005). Houve melhora na concentra\u00e7\u00e3o de hemoglobina (p= 0,0004), com eleva\u00e7\u00e3o ap\u00f3s a emboliza\u00e7\u00e3o, sem varia\u00e7\u00e3o subsequente \u00e0 miomectomia. N\u00e3o ocorreu varia\u00e7\u00e3o significante do horm\u00f4nio fol\u00edculo estimulante, (p=0,17). N\u00e3o foi constatado nenhum caso de fal\u00eancia ovariana, mas uma das pacientes apresentou atrofia de endom\u00e9trio. Duas pacientes engravidaram, com bons indicadores obst\u00e9tricos. Quanto aos sinais e sintomas, houve melhora ap\u00f3s a emboliza\u00e7\u00e3o, que se manteve ap\u00f3s a miomectomia. CONCLUS\u00c3O: a emboliza\u00e7\u00e3o arterial com part\u00edculas de PVA-PVAc esf\u00e9rico mostrou-se promissora no preparo para uma interven\u00e7\u00e3o cir\u00fargica com retirada dos miomas, pois, associou-se \u00e0 redu\u00e7\u00e3o do volume uterino, \u00e0 diminui\u00e7\u00e3o do sangramento operat\u00f3rio e tornou poss\u00edvel a utiliza\u00e7\u00e3o de incis\u00f5es menores, aumentando a chance de preserva\u00e7\u00e3o do \u00fatero.<\/jats:p>","DOI":"10.1590\/s0100-69912013000500007","type":"journal-article","created":{"date-parts":[[2014,1,11]],"date-time":"2014-01-11T15:06:37Z","timestamp":1389452797000},"page":"386-391","source":"Crossref","is-referenced-by-count":9,"title":["Emboliza\u00e7\u00e3o das art\u00e9rias uterinas com part\u00edculas de PVA-PVAC esf\u00e9rico como preparo para posterior ressec\u00e7\u00e3o cir\u00fargica de miomas"],"prefix":"10.1590","volume":"40","author":[{"given":"Juraci","family":"Ghiaroni","sequence":"first","affiliation":[{"name":"Universidade Federal do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaudencio Espinosa","family":"Lopez","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio Carlos","family":"Coutinho Junior","sequence":"additional","affiliation":[{"name":"Clinica de Diagn\u00f3sticos por Imagem,  BR"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Schanaider","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","first-page":"792","article-title":"The starvation operation for malignancy in the external carotid area","volume":"17","author":"Dawbain RHM","year":"1904","journal-title":"JAMA."},{"issue":"8976","key":"ref2","doi-asserted-by":"crossref","first-page":"671","DOI":"10.1016\/S0140-6736(95)92282-2","article-title":"Arterial embolisation to treat uterine myomata","volume":"346","author":"Ravina JH","year":"1995","journal-title":"Lancet."},{"issue":"4","key":"ref3","doi-asserted-by":"crossref","first-page":"517","DOI":"10.1016\/S1051-0443(97)70603-1","article-title":"Preliminary experience with uterine artery embolization for uterine fibroids","volume":"8","author":"Goodwin SC","year":"1997","journal-title":"J Vasc Interv Radiol."},{"issue":"3","key":"ref4","doi-asserted-by":"crossref","first-page":"625","DOI":"10.1148\/radiology.208.3.9722838","article-title":"Uterine artery embolization for the management of leiomyomas: quality-of-life assessment and clinical response","volume":"208","author":"Worthington-Kirsch RL","year":"1998","journal-title":"Radiology,"},{"issue":"2","key":"ref5","doi-asserted-by":"crossref","first-page":"403","DOI":"10.1097\/00006250-200402000-00044","article-title":"Uterine artery embolization","volume":"103","year":"2004","journal-title":"Obstet Gynecol."},{"issue":"2 Pt 1","key":"ref6","first-page":"387","article-title":"ACOG practice bulletin.
