Medir a veia cava inferior de lado?

Effect of positional changes on inferior vena cava size
Eur J Echocardiogr (2011) 12 (4): 322-325
.
Aim To study the effect of positional change on inferior vena cava (IVC) diameter. The influence of positional change on IVC size is not well studied. Although the American Society of Echocardiography guidelines for chamber quantification recommend imaging the IVC in the left lateral position, many labs routinely image the IVC from the supine position.
.
Conclusions The IVC dimension is larger in the supine position independent of the cardiac cycle. This may be due to increased intra-abdominal pressure and compression of the IVC by the liver in the left lateral position. HV systolic and diastolic peak Doppler velocities were not influenced by position.

Alguém mede a veia cava inferior no decúbito lateral?
Apesar da diretriz, sempre buscamos o decúbito dorsal para avaliar o subcostal.
