Clinical Investigation TIPS
Part of the following topical collections:
  1. TIPS



To evaluate short-term clinical efficacy, complications and possible passive stent expansion of transjugular intrahepatic portosystemic shunt (TIPS) creation using the new controlled expansion ePTFE covered stent (VCX), for portal hypertension complications.


Between 7/2016 and 3/2018, 75 patients received TIPS using VCX. Thirty-nine patients with VCX dilated with an 8-mm angioplasty balloon underwent computed tomography (CT) study during follow-up and CT data were used to measure stent diameter. The CT measurement technique was validated by ex vivo experiment.


TIPS indications were: refractory ascites (n = 45), variceal bleeding (n = 22), other (n = 8). Mean follow-up was 5.8 months (± 4.5, range 1–20). In 69 patients, TIPS was dilated to 8 mm of diameter reaching the hemodynamic target of a portosystemic pressure gradient (PSG) < 12 mmHg. In six patients, not reaching the hemodynamic target the stent was dilated to 10 mm of diameter during the same session with a final PSG < 12 mmHg. Overall clinical success was achieved in 66/75 (88%) patients (80% in refractory ascites, 95% variceal bleeding, 100% other). Grade II–III encephalopathy was observed in five patients (6%). TIPS revision with stent dilatation to 10 mm was performed in seven patients: in three patients with ascites persistence, without evidence of stent dysfunction and in four patients for stent stenosis. One patient underwent stent reduction. Fourteen patients (18%) died during follow-up of causes not related to TIPS. Five patients (6%) underwent liver transplant. No passive stent expansion was detected by CT measurements.


VCX for TIPS creation retains its diameter over a short-term period and is associated with a good clinical outcome with a reasonably low complication rate.
