Objective To compare of the clinical using effect of implantable venous -access port(VAP) among different methods and the postoperative complication.Methods From 2011 to 2014,a total of 359 patients with VAP were included in this study.All patients were divided into two groups according to the surgery approaches methods,307 cases were implanted through internal jugular vein,and other 52 cases were through subclavian vein intubation.Statistics of postoperative flow conditions and complication between the two groups were gathered and com-pared.Results There were 3 cases of postoperative infected,and 13 cases were not free of transfusion,while 2 cases catheter were shed and shifted in the 307 cases of implantation through internal jugular vein,the complication rate was 5.86%;In other group,which in total of 52 cases of implantation through subclavian vein,including 2 cases were post-operative infected,6 cases were not free of transfusion,2 cases are of catheter fracture and5 cases were local hemato-ma,the complication rate was 28.85%.There was difference in rate of catheter leakage,catheter tip dystopy and cath-eter related infection between two groups[the proportion of through internal jugular vein vs that the group through sub-clavian vein:5.86%(18 /307)vs 28.85%(15 /52),χ2 =28.140,P =0.000].Conclusion The study suggests that the two ways of different operation methods of VAP are safe and reliable for long term intermittent venous access.The internal jugular vein implanted group has a slight advantage over the group of subclavian vein implanted,when it comes to develop the patients′living quality.

Objective To evaluate the clinical indicat ion and effect of inferior vena cava filter. Methods 17 cases of deep venous thrombosis were treated w ith insertion of the inferior vena cava filter. In 4 cases the thrombosis were d rawn by Hydrolyser catheter with popliteal vein punction, in another the thrombo sis were analysed by Urokinase with vena dorsalis pedis injection.Results The filters were successfully inserted. No seious complication were observed. The thrombosis were discharged in 2 cases with Hydr olyser catheter ,and in 4 cases with Urokinase analyse. No pulmonary thromboembo lism was observed.Conclusion The inferior vena cava filter insertion is a e ffective method to provent pulmonary thromboembolism, and a safe step for the in tervenional therapy to the deep venous thrombosis.

ObjectiveTo investigate the feasibility and isolation efficiency of percutaneous selective isolated hepatic perfusion chemotherapy(PSIHP). MethodsSix pigs underwent the procedure of routine transhepatic arterial infusion(HAI) and 6 underwent PSIHP.5-FU was used in this study. The drug(5-FU) (concentration) of blood from hepatic and systemic veins of both groups was observed. Liver tissue was (investigated) for pathologic changes. ResultsThe peak level of 5-FU concentration in blood from right (hepatic) vein and systemic vein in HAI group was(4082.530415.213)mg/L and (1682.230216.834)mg/L respectively.In PSIHP group, the peak level(5-FU) was(5321.711517.318)mg/L and(510.83452.518)mg/L, respectively.There was a statistically significant difference between HAI group an PSIHP group(P
