AIMS AND OBJECTIVES: To evaluate technical feasibility, long-term primary patency and clinical outcome of the transjugular intrahepatic portosystemic shunt (TIPS) through the struts of the previously placed stents.
MATERIALS AND METHODS: Retrospective evaluation of seven consecutive patients (three male and four female, age range 13-65 years, median 28) out of a total 95 patients, who underwent TIPS through the strut of the previously placed stents of hepatic vein (HV), inferior vena cava (IVC) or TIPS in a single tertiary care hospital. Six of the patients were diagnosed with Budd-Chiari syndrome (BCS) and one with alcohol-induced chronic liver disease (CLD). Kaplan-Meier test was used to calculate 18- and 60-month primary patency rate of TIPS stent.
RESULTS: TIPS through the strut of a previously placed stent was technically successful in all the patients (100%). The TIPS was direct intrahepatic portosystemic shunt (DIPS) in 5/7 cases, due to occluded HV. Mean portosystemic pressure gradient (PPG) reduced from 24 mmHg ± 5.9 (range, pre-TIPS 15-31 mmHg) to 8.57 mmHg ± 4.4 (range, post-TIPS, 3-14 mmHg). One patient required three sessions of TIPS revisions. Another patient needed TIPS revision after 5 years of TIPS creation. All the patients showed improvement in clinical symptoms and in mean Child-Turcotte-Pugh (CTP) score and modified end-stage liver disease (MELD) score during mean follow-up period 40.57 month ± 34.9 (range 3-100 month). Primary patency rates of TIPS stent measured with Kaplan-Meier estimate at 18- and 60-month follow-up were 80% (95% CI, 37-97%) and 40% (95% CI, 10-97%), respectively.
CONCLUSION: TIPS through the strut of a previously placed stent is technically feasible with good long-term primary patency and clinical outcome.
