Abstract:
Objective To discuss the application value of liver shear wave velocity(SWV)and its correlation with portal vein pressure in evaluating the efficacy of interventional therapy for Budd-Chiari syndrome(BCS).Methods The clinical data of 40 BCS patients,who were admitted to the Affiliated Hospital of Xuzhou Medical University of China to receive treatment between April 2020 and April 2022,were collected.During interventional procedure,the hepatic venous pressure gradient(HVPG)was determined separately before and after recanalization of the treated vessels,the liver SWV was determined at one day before,2 days,1 month and 3 months after the treatment,and the above indexes were statistically analyzed.Results Successful initial interventional therapy was accomplished in all patients.The preoperative one-day,postoperative 2-day,one-month and 3-month mean liver SWV values were(2.34±0.36)m/s,(1.74±0.36)m/s,(1.62±0.30)m/s,and(1.56±0.28)m/s respectively.The differences in the mean liver SWV between its preoperative value and its postoperative 2-day,one-month and 3-month value were statistically significant(all P＜0.05),and statistically significant difference in the mean liver SWV also existed between postoperative 2-day value and postoperative 3-month value(P＜0.05).The mean HVPG decreased from preoperative(15.19±2.35)mmHg(1 mmHg=0.133 kPa)to postoperative(6.44±1.34)mmHg(P＜0.05).The preoperative one-day liver SWV was positively correlated with preoperative HVPG(r=0.803,P＜0.01).The postoperative 2-day liver SWV also carried a positive correlation with the postoperative HVPG(r=0.844,P＜0.01).The difference value(D-value)between preoperative liver SWV value and postoperative 2-day liver SWV value was(0.59±0.27)m/s,and the D-value between preoperative HVPG value and postoperative HVPG value was(8.75±1.92)mmHg,and a positive correlation existed between the above two D-values(r=0.676,P＜0.01).Conclusion There is a good correlation between liver SWV and HVPG,which can be used to evaluate the postoperative efficacy of BCS patients after receiving interventional therapy.(J Intervent Radiol,2023,32:1178-1183)
