Purpose: To report the safety and efficacy of occluded transjugular intrahepatic portosystemic shunts (TIPS) recanalization using the stiffening cannula (SC) technique. Materials and Methods: This is a retrospective, single-centre, single-arm study, investigating the safety and efficacy of transjugular recanalization of occluded TIPS using the SC (Cook, Ind. USA), in cases of failure to cross the occlusion with standard angiographic catheters and balloons. Between October 2015 and October 2017, a total of 15 TIPS revisions have been performed due to shunt occlusion. In all cases in which the initial standard approach to cross the lesion failed, the SC technique was used. The study’s primary efficacy outcome measure was technical success, and primary safety outcome measure was immediate procedure-related complications rate. Secondary outcome measures included restenosis and peri-procedural adverse events rates. Results: Among 15 patients with shunt occlusion, seven (7/15; 46.5%) were successfully crossed via transjugular access, using standard angiographic catheters. In the remaining eight patients (nine procedures), recanalization with the SC technique was performed. Technical success was 100%. No complications or peri-procedural adverse events were noted. Restenosis rate was 11.1% (1/9 cases) as only one case of re-occlusion was noted, 3 months following recanalization using sole balloon angioplasty and successfully retreated using the SC technique and stent graft deployment. Conclusions: The SC technique is a safe and efficient option for the recanalization of occluded TIPS, in cases in which conventional lesion crossing is not feasible, in order to avoid percutaneous transhepatic access or new TIPS creation. © 2018, Springer Science+Business Media, LLC, part of Springer Nature and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE).
