【摘要】：目的在脱离X线的条件下,探讨超声引导下在兔体内建立直接性门腔静脉分流术(DIPS)通道的可行性及安全性。方法 10只实验兔在超声引导下于剑突下肝下缘经皮穿刺门静脉右支(RPV),然后调整进针角度,穿刺肝后段下腔静脉(RHSIVC)并放入导丝,建立肝内直接性门腔静脉分流通道。术后对实验兔进行解剖,观察导丝是否进入RHSIVC内,是否有肝包膜下血肿、腹腔出血及器官损伤等并发症。结果 9只实验兔在超声引导下成功实施经皮经肝RPV至RHSIVC穿刺术,1只兔因术中麻醉意外致死。术后解剖证实9只兔的穿刺导丝均成功由RPV送入近心端的RHSIVC,且无肝包膜下血肿、腹腔出血及器官损伤等。结论在兔体内经皮RPV与RHSIVC的直接性门腔静脉分流通道具有一定的安全性和可行性。
[Abstract]:Objective to investigate the feasibility and safety of direct portal vena cava shunt (DIPS) channels in rabbits under the guidance of ultrasound.Methods under the guidance of ultrasound, the right portal vein (RPVV) was punctured at the inferior edge of the hepatic process in 10 experimental rabbits, and then the angle of the needle was adjusted, and the RHSIVC was inserted into the posterior segment of the liver to establish a direct portal vena cava shunt channel.The experimental rabbits were dissected after operation to observe whether the guide wire entered into RHSIVC, whether there were complications such as hepatic subcapsular hematoma, intraperitoneal hemorrhage and organ injury.Results the percutaneous transhepatic RPV to RHSIVC puncture was performed successfully in 9 experimental rabbits under the guidance of ultrasound.Postoperative anatomy confirmed that all of the 9 rabbits were successfully transferred from RPV to the proximal heart without subcapsular hematoma, abdominal hemorrhage and organ injury.Conclusion the direct porta vena cava shunt channel between RPV and RHSIVC is safe and feasible in rabbits.
