Abstract
Establishment of transjugular intrahepatic portosystemic shunts TIPS constitutes a standard procedure in patients suffering from portal hypertension The most difficult step in TIPS placement is blind puncture of the portal vein This study aimed to evaluate threedimensional mapping of portal vein branches and targeted puncture of the portal veinTwelve consecutive patients suffering from refractory ascites by liver cirrhosis were included in this retrospective study to evaluate feasibility technical success and procedural time of Carm CTtargeted puncture of the portal vein As a control 22 patients receiving TIPS placement with fluoroscopyguided blind puncture were included to compare procedural timeTechnical success could be obtained in 100 of the study group targeted puncture and in 955 of the control group blind puncture Appropriate threedimensional Carm CTguided mapping of the portal vein branches could be achieved in all patients The median number of punctures in the Carm CTguided study group was 2 ± 13 punctures Procedural time was significantly lower in the study group 148 ± 82 min compared to the control group 326 ± 227 min p = 002The scientific guarantor of this publication is PD Dr Dominik Ketelsen MD The authors of this manuscript declare no relationships with any companies whose products or services may be related to the subject matter of the article The authors state that this work has not received any funding No complex statistical methods were necessary for this paper Institutional Review Board approval was not required due to retrospective study design Written informed consent was obtained from all subjects patients in this study Methodology retrospective observational study performed at one institution
