Abstract:
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.
