Objective: Ultrasound assessment of inferior vena cava (IVC) collapsibility is performed to
determine the volume status of critically ill patients. We propose a new acoustic window
for visualizing a vein in a prone patient.
Case Presentation: A healthy volunteer took part in the study. The study protocol includes
two stages: 1) performing a magnetic resonance imaging (MRI) examination to determine
the projection of a certain IVC area on the posterior chest surface (holotopy), 2) performing
an ultrasound scanning in the area of IVC projection in order to identify it and determine
its dimensions.
Conclusion: The 11th intercostal space parallel to the paraspinal line allows to visualize
the IVC in the prone position. This gives a potential opportunity to use it to assess the IVC
collapsibility. Its potential advantage is the ability to assess the compressibility of IVC in
the antero-posterior direction
