Feasibility of electromagnetically guided transjugular intrahepatic portosystemic shunt procedure.
Objectives:To develop an electromagnetic navigation technology for transjugular intrahepatic portosystemic shunt (TIPS) creation and translate it from phantom to anin-vivolarge animal setting. Material and methods:A custom-designed device for TIPS creation consisting of a stylet within a 5 French ca...

Material and methods:A custom-designed device for TIPS creation consisting of a stylet within a 5 French catheter as well as a software prototype were developed that allow real-time tip tracking of both stylet and catheter using an electromagnetic tracking system. Feasibility of navigated TIPSS creation was tested in a phantom by two interventional radiologists (A/B) followed byin-vivotesting evaluation in eight domestic pigs. Procedure duration and number of attempts needed for puncture of the portal vein were recorded. Results:In the phantom setting, intervention time to gain access to the portal vein (PV) was 144 ± 67 s (A) and 122 ± 51 s (B), respectively. In thein-vivotrials, TIPS could be successfully completed in five out of eight animals. Mean time for the complete TIPS was 245 ± 205 minutes with a notable learning curve towards the last animal. Conclusions:TIPS creation with the use of electromagnetic tracking technology proved to be feasiblein-vitroas well asin-vivo. The system may be useful to facilitate challenging TIPSS procedures. pubtype: Academic Journal doctype: diagnostic images pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
