Hepatic vein restenosis occurred in one case 8 months after balloon dilatation,and treated with stent implantation.Inferior vena cava restenosis occurred in one case 2 years after balloon dilation,and trea- ted with another balloon expanding.Patients remained completely asymptomatic at 4 months to 5 years of follow-up.Conclusion The venacavographic balloon angioplasty and metallic stent replacement are safe and useful for post-OLT with venous outflow obstruction.","PeriodicalId":332100,"journal":{"name":"Chinese Journal of Organ Transplantation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124383413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mouse-to-rat heterotopic heart transplantation model was established. The hearts of normal BALB/C mice were harvested as control group. The xengrafts were divided into three groups: ddH2O group, control oligodeoxynucleotide group and ICAM-1-ASO group (n=10 in each group). Each donor was injected intravenously with ddH2O, control oligodeoxynucleotide or ICAM-1-ASO 6 h before operation respectively. At 48th h after transplantation, 5 xenografts in each group were collected for histopathological examination. The expression of ICAM-1 protein and mRNA in cardiac xenografts was detected by immunohistochemical method and semiquantitative reverse transcriptase polymerase reaction method. The mean survival time (MST) in each xenograft group was recorded in terms of the other 5 transplanted grafts by palpation per 12 h.Results Faint ICAM-1 expression was observed in the control group. In ddH2O group and control oligodeoxynucleotide group, capillary endothelial cells and myocytes of the grafts strongly expressed ICAM-1 and the relative density values (ICAM-1/β-actin) were also significantly higher with extensive hyperemia, edema, hemorrhage and inflammatory cells infiltrated in both groups than those in the control group. Comparatively, in the ICAM-1-ASO group, fainter ICAM-1 expression was observed and the relative density value (ICAM-1/β-actin) was also significantly lower with pathological improvement compared with those in ddH2O group and control oligodeoxynucleotide group. The MST in ICAM-1-ASO was (66.4±2.61) h, which was significantly prolonged as compared with ddH2O group and control oligodeoxynucleotide group.Conclusion ICAM-1-ASO can sequence-dependently inhibit the ICAM-1 expression of xenografts, suppress xenograft rejection and prolong the survival time of xenografts.","PeriodicalId":332100,"journal":{"name":"Chinese Journal of Organ Transplantation","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123822956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
