Preprocedure demographics, Child\u2013Pugh, model for end-stage liver disease and technical variables were recorded. Outcomes measured included technical and clinical success, complications, 30-day mortality, as well as necessity for TIPS revision.

Clinical success as defined as a reduction or improvement in presenting symptoms was 88.9% (8\/9) and 100% (18\/18) in the constrained and conventional groups, respectively (p = 1). The average reduction in portosystemic gradient was lower in the constrained group, 6.1 mmHg compared with 10.6 mmHg in the conventional group (p = 0.73). The rate of hepatic encephalopathy following TIPS placement was higher in the conventional group [16.7% (3\/18)] compared with 0% in the constrained group (p = 0.52). The percentage of patients requiring TIPS revision was lower in the constrained group, although the results were not significant (11.1 vs 22.2%, p = 0.63).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>Primary constrained TIPS is a feasible modification to conventional TIPS with similar technical and clinical success rates.
