Six pigs underwent implantation of a portal vein infusion port by transjugular access. The technical success rate was 100% (n = 6), with no surgical complications or deaths. At 1 month after implantation, the catheter tip had moved from the splenic vein to the main portal vein, while the catheter protruded into the right ventricle through the right atrium in all cases. Hence, the infusion port system has not been used in clinical practice due to its obvious displacement after implantation. However, this study provides a new idea for future exploration of portal vein infusion pathways.
六头猪通过经颈静脉途径植入门静脉输液端口。技术成功率为100%（n = 6），无手术并发症或死亡。植入后1个月，导管尖端从脾静脉移至门静脉主干，且在所有病例中导管均经右心房突入右心室。因此，由于植入后明显移位，该输液端口系统尚未用于临床实践。然而，本研究为未来门静脉输注途径的探索提供了新思路。
