Methods Six patients with hepatic venous obstruction were enrolled into this study.3 patients were treated with anterograde transhepatic angioplasty,the other 3 patients were treated with retrograde angioplasty via inferior vena cava(IVC).The diameter of hepatic vein and hepatic venous pressure gradient (HVPG) were recorded before and after therapy.Data were analyzed with Paired Samples t Test. Results All PTA procedures were performed successfully.After therapy the diameter of hepatic vein was increased from (0.90±1.03)mm to (5.67±0.34)mm( P <0.001) and the HVPG was declined from (4.15±0.53)kPa [(31.23±4.04)mmHg] to (1.21±0.10)kPa [(9.13± 0.76 )mmHg] ( P <0.001).Difference showed statistical significance.The patients’clinical signs and symptoms were improved obviously.There was no serious procedure related complication except one patient experienced intraperitioneal bleeding. Conclusions PTA is a safe and effective treatment for patients with primary hepatic venous obstruction.展开更多
