Abstract: Magistrsko delo vsebuje raziskavo vpliva povezave med votlo cevjo in zaprto-celičnem polnilom pri upogibni obremenitvi. Analizo smo izvedeli s pomočjo programa Abaqus, s katerim smo s privzetimi parametri zaprto-celičnega polnila in votle cevi izdelali sestavljen model ter izvedli simulacijo sestavljenega elementa. Z eksplicitno metodo smo ugotavljali vpliv koeficienta trenja pri izvedenem simuliranju upogibne obremenitve. Namen je pridobitev novih informacij in rezultatov za nadaljnji študij in uporabo zaprto-celičnega polnila pri različnih aplikacijah.Keywords: votla cev, zaprto-celično polnilo, koeficient trenja, Abaqus, numerični modelPublished in DKUM: 24.02.2016; Views: 1450; Downloads: 126 Full text (2,54 MB)
Abstract: Primary leiomyosarcoma of the vena cava is a rare tumor. We describe a 63-year-old female in whom a mass was found upon ultrasonographic examination of the abdomen after persistent pain in the right upper quadrant. CT and MRI revealed a malignant intraluminal growth in the inferior vena cava. Radical resection was undertaken to remove the tumor. The inferior vena cava was reconstructed using a PTFE graft. Resection margins were free of tumor. Postoperative complications included extended thrombosis below the surgical site and smaller pulmonary emboli. A vena-cava filter was inserted to prevent further complications. Twelve months after the first procedure local subcutaneous metastases were observed. Metastases were subsequently removed. We discuss our case to deepen our understanding of this extremely rare disease.Keywords: leiomiosarkom, spodnja votla vena, radikalna resekcija, pooperativna tromboza žilne protezePublished in DKUM: 30.12.2015; Views: 1680; Downloads: 74 Link to full textThis document has many files!
