Purpose: To determine if, with use of magnetic resonance (MR)
imaging guidance alone, transcaval puncture of the supe-
rior mesenteric vein (SMV) and/or portal vein is feasible
with a percutaneous femoral vein approach.
Materials and
Methods:
The Institutional Animal Care and Use Committee ap-
proved the animal studies. Ten inferior vena cava (IVC)­
SMV punctures were performed in six pigs. An active MR
intravascular needle system was used for all transvascular
punctures, and all procedures were performed with a
1.5-T MR unit. The needle was introduced via a 12-F
