Size and shape of the inferior vena cava before and after a fluid challenge: a pilot study.

CONCLUSIONS: The elliptic section should be considered when assessing IVC size. AP diameters are shorter and more affected by the respiratory cycle. After a fluid challenge, an increase of blood velocity associated with unchanged AP diameters may suggest fluid responsiveness. PMID: 30482000 [PubMed - as supplied by publisher]
