A TPM ganhou import\u00e2ncia devido ao crescente n\u00famero de cirurgias bari\u00e1tricas sendo realizadas.  Objetivo: Relatar complica\u00e7\u00e3o rara ap\u00f3s cirurgia bari\u00e1trica, por\u00e9m grave e de dif\u00edcil manejo. Tentar identificar algumas caracter\u00edsticas comuns aos pacientes e discutir poss\u00edveis causas, comparando a pouca literatura dispon\u00edvel.  M\u00e9todos: Descrevemos seis casos de TPM em mulheres jovens com diferentes apresenta\u00e7\u00f5es.  Resultados: Todos os seis casos ocorreram em mulheres jovens de 29 a 41 anos sem obesidade grave - \u00edndice de massa corporal - IMC: 36 a 39 e com peso que variou de 105 a 121 kg. As pacientes apresentavam poucas comorbidades (todas relacionadas \u00e0 s\u00edndrome metab\u00f3lica) e esteatose hep\u00e1tica moderada, sem sinais de cirrose. Cinco pacientes usavam contraceptivos orais at\u00e9 dias antes da cirurgia. Uma paciente apresentou resultado positivo para trombofilia. Cinco pacientes foram submetidas a gastrectomia vertical e apenas uma submetida ao bypass g\u00e1strico sem complica\u00e7\u00f5es durante a cirurgia (tempo m\u00e9dio de opera\u00e7\u00e3o: 61,3 min, variando de 52 a 91 min). A dura\u00e7\u00e3o m\u00e9dia do seguimento ap\u00f3s a hospitaliza\u00e7\u00e3o foi de 12,3 meses (varia\u00e7\u00e3o: 7 a 18 meses) e at\u00e9 o momento apenas uma paciente n\u00e3o teve recanaliza\u00e7\u00e3o.  Conclus\u00e3o: A frequ\u00eancia da TPM parece ser maior em mulheres e ap\u00f3s gastrectomia vertical. Nossos achados indicam que pacientes com dor abdominal semanas ap\u00f3s a cirurgia bari\u00e1trica devem ser investigados.<\/jats:p>","DOI":"10.1590\/0100-6991e-20202480","type":"journal-article","created":{"date-parts":[[2020,6,3]],"date-time":"2020-06-03T12:45:58Z","timestamp":1591188358000},"source":"Crossref","is-referenced-by-count":4,"title":["Trombose venosa portomesent\u00e9rica ap\u00f3s cirurgia bari\u00e1trica: s\u00e9rie de casos"],"prefix":"10.1590","volume":"47","author":[{"given":"Fernando de","family":"Barros","sequence":"first","affiliation":[{"name":"Universidade Federal Fluminense,  Brasil; Hospital S\u00e3o Lucas,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1304-5075","authenticated-orcid":false,"given":"Eduardo de Souza","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Hospital S\u00e3o Lucas,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nelson","family":"Fiod","sequence":"additional","affiliation":[{"name":"Hospital S\u00e3o Lucas,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henrique Sergio Moraes","family":"Coelho","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvio","family":"Martins","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"4","key":"ref1","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1007\/s11695-012-0864-0","article-title":"Metabolic\/bariatric surgery worldwide 2011","volume":"23","author":"Buchwald H","year":"2013","journal-title":"Obes Surg"},{"issue":"8","key":"ref2","doi-asserted-by":"crossref","first-page":"2353","DOI":"10.1007\/s11695-018-3202-3","article-title":"Which bariatric procedure is the most popular in the world?
