Does advanced chronic kidney disease impact transjugular intrahepatic portosystemic shunt efficacy and safety?

Background and study aims : There are currently limited data available summarizing the clinical outcomes and safety of tran- sjugular intrahepatic portosystemic shunts (TIPS) in cases of advanced chronic kidney disease (CKD). The study aimed to assess efficacy and safety of TIPS in patients with advanced CKD. Patients and methods : Seventeen patients (M :F 8 :9, age 55 years, MELD 24) with grade 4-5 CKD who underwent TIPS for ascites (n = 7) or varices (n = 10) were analyzed. The primary outcome was TIPS efficacy - assessed by comparing paracentesis frequency and diuretic regimen pre- and post-TIPS among ascites patients - and through bleeding cessation in variceal bleeding patients. Other outcomes included hepatic encephalopathy (HE), GFR increase, and mortality. Results : Median baseline GFR was 19.9 mL/min. No patients were hemodialysis dependent. Median post-TIPS pressure gradient was 8 mm Hg. Among ascites patients, 5/6 (83%) were TIPS responsive, with reduced or stable diuretics in 4/5 (80%). Among variceal hemorrhage cases, bleeding cessation rate was 90% (9/10). New or worsening HE incidence was 47% (8/17), and one patient required shunt reduction. Of 8 patients with lab follow-up, 6 (75%) demonstrated significant GFR increase (42.2 versus 20.0 mL/min, P = 0.028). The 90-day mortality incidence was 29% (5/17). Conclusions : In conclusion, TIPS can potentially address ascites and variceal bleeding in advanced CKD patients, though HE incidence may be increased. Further investigation in larger cohorts may corroborate these results. (Acta gastroenterol. belg., 2017, 80, 243-248).
