Abstract:
Objective To discuss the efficacy and safety of transjugular intrahepatic portosystemic shunt(TIPS)for portal hypertension with portal vein thrombosis(PVT).Methods A total of 31 patients with portal hypertension complicated by PVT,who underwent TIPS at the Chinese PLA General Hospital between December 2017 and October 2022,were enrolled in this study.The clinical data,including preoperative laboratory tests,operation pattern,intraoperative portal vein pressure(PVP),postoperative follow-up ultrasound or enhanced CT examination findings,and the presence or absence of hepatic encephalopathy(HE),were collected.Paired t-test was used to compare the differences in PVP before and after stenting,Kaplan-Meier curve was used to analyze the postoperative shunt patency rate,rebleeding rate,incidence of HE,and survival rate.Log-rank test was used to analyze the differences in follow-up results between the patients having cavernous transformation of portal vein(CTPV)and the patients having no CTPV.Results The technical success rate of TIPS procedure was 93.55％(29/31).In the 29 patients with successful surgery,the mean PVP value decreased from preoperative(30.15±4.61)mmHg to postoperative(20.84±5.57)mmHg,the difference was statistically significant(t=8.975,P＜0.05).The postoperative median follow-up time was 22.90 months(range of 4.50-61.80 months).During the follow-up period,24.14％of patients(7/29)developed shunt tract dysfunction,17.24％of patients(5/29)developed rebleeding,17.24％of patients(5/29)developed HE,and 5 patients(5/29,17.24％)died.Ten patients(10/29,34.48％)with PVT were complicated by CTPV,among them 5 patients had shunt dysfunction,3 patients had rebleeding,one patient developed HE,and 3 patients died.Of the 19 patients who having no coexisting CTPV,shunt dysfunction was seen in 2,rebleeding in 2 and HE in 4,and 2 patients died.The incidences of shunt tract dysfunction and rebleeding in the patients having CTPV were obviously higher than those in the patients having no CTPV(both P＜0.05),while no statistically significant differences in the incidences of HE and death existed between the two groups(both P＞0.05).Conclusion TIPS can effectively reduce the PVP in patients with PVT.The incidences of shunt tract dysfunction and rebleeding in the PVP with coexisting CTPV are remarkably higher than those in the PVT patients with no coexisting CTPV.(J Intervent Radiol,2024,33:537-542)
