Objective To summary the clinical applied value of interventional therapy in hepatic venous outflow obstruction after orthotopic liver transplantation(OLT).Methods The clinical data of 27 patients suspect with hepatic outflow obstruction out of OLT patients were analyzed retrospec- tively.Most of them presented with liver dysfunction,like ascites,jaundice,or hydropsia of lower ex- tremity as BCS.These patients accepted venography and endovascular treatment if venous outflow ob- struction was found.Results By venography,one case of thrombus in inferior vena cava,one case of hepatic vein stenosis,13 cases of inferior vena cava stenosis(3 cases were associated with hepatic vein stenoses)were identified.Stent implantation was successfully performed on 10 patients,and balloon angioplasty on 4 patients.Rapid,dramatic resolution of symptoms was achieved in those patients. 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.

Objective To investigate the inhibitory effect of intercellular adhesion molecule-1 antisense oligodeoxynucleotide (ICAM-1-ASO) on the rejection of cardiac xenograft as well as the expression of ICAM-1 in the xenograft.Methods BALB/C mice and Lewis rats served as donors and recipients respectively. 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.
