Objective The reseach of hepatic vein (HV) and inferior vein cavity(IVC) obstruction recanalized with catheter needle were evaluated. Methods 16 cases of BCS diagnosed with angiography in recent 5 years were all undergone interventional treatment. Five with HV web occlusion principally and 9 with IVC complete occlusion were treated with introducing a catheter needle to penetrate the block through jugular vein or femoral vein. Stenosis or needle track was dilated with balloon. Stent was planted to IVC in 10 cases. Results All cases were successful in technic including a segmental obstrution of IVC and with a lower IVC atresia. Venography demonstrated the patency of blood flow. HV pressure of 5 cases was reduced 1.85kPa, and IVC pressure of 11 cases was reduced 1.21kPa on an average.Conclusions The use of catheter needle technique increases the successful rate in BCS treatment.
