Variables assessing technical quality of the transjugular intrahepatic portosystemic shunt (TIPS) intervention88
| Author, year (Ref) | Technical success (%) | Reduction in portosystemic pressure gradient mm Hg (%) | Secondary patency rate (%) |
| Lebrec 199629 | 77 | 6 (30) | 46 |
| Rössle 200058 | 100 | 14 (58) | 93 |
| Gines 200286 | 97 | 10.4 (54) | 91 |
| Sanyal 200352 | 94 | 11.5 (58) | >90 |
| Salerno 200487 | 89 | 13.8 (61) | 82 |
The secondary patency rate is the patency achieved by shunt revision. The French study shows exceptional values.
