Abstract:
Objective:To compare the effectiveness and safety of mechanical thrombus aspiration combined with superior mesenteric artery transcatheter thrombolysis with those of simple superior mesenteric artery transcatheter thrombolysis in the treatment of portal vein-superior mesenteric vein thrombosis.Methods:A retrospective case-control study was used to analyze the clinical data of 27 patients with portal vein thrombosis treated by interventional therapy in Beijing Friendship Hospital Affiliated to Capital Medical University from February 2020 to October 2022. According to different interventional procedures, they were divided into two groups: 13 cases were treated with mechanical thrombus aspiration combined with superior mesenteric artery catheterization thrombolysis (combined treatment group), and 14 cases were treated with superior mesenteric artery catheterization thrombolysis alone (catheterization thrombolysis group). The postoperative and preoperative portal vein thrombus grade, catheterization thrombolysis time, parenteral nutrition time and operation-related complications were observed and compared between the two methods, and the incidence of long-term intestinal necrosis was compared after postoperative follow-up. Measurement data of normal distribution were expressed as mean±standard deviation( ± s), t-test was used for comparison between groups. Counting data were expressed as cases and percentage(%), and comparison between groups was used Chi-square test or Fisher exact probability method. Results:There was significant difference in the grade of portal vein thrombosis between the combined treatment group and the catheterization thrombolysis group( P<0.05). The thrombolytic time of catheterization in the two groups was (2.38±0.74) d and (4.79±1.15) d, respectively, and the time of parenteral nutrition was (4.08±2.87) d and (8.50±3.16) d, respectively. The difference was statistically significant ( P<0.05). There was no significant difference in operation-related complications between the two groups ( P>0.05). There were no severe injury of liver and kidney function in both groups. One patient in each group underwent long-term enterectomy. Conclusions:Mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis is safe and effective in the treatment of portal vein thrombosis. Compared with simple superior mesenteric artery thrombolysis, mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis can increase the rate of thrombus clearance and reduce the time of thrombolysis and parenteral nutrition support.
