Table 4 Definitions of the variables analysed in table 3 (eg. Measurements, Diameters, lengths between various aortic branches)

From: A statistical model that predicts the length from the left subclavian artery to the celiac axis; towards accurate intra aortic balloon sizing

Measurement 1 from the jugular notch to the trans-pyloric plane LSA-CA from the left subclavian take off to the celiac axis
Measurement 2 from the jugular notch to the anterior superior iliac spine LSA-Renal from the left subclavian take off to the renal artery
Measurement 3 from the middle point between the jugular
notch and the sternal angle to the
trans-pyloric plane
LSA-Bifur from the left subclavian take off
to the aortic bifurcation
Measurement 4 from the middle point between the jugular notch and the sternal angle to the anterior superior iliac spine. LSA-Inser from the left subclavian artery take off to the IAB insertion 2 cm below the mid-inguinal ligament
Measurement 5 from the jugular notch to the middle point in the line between the anterior superior iliac spine and symphysis pubis Depth the depth of the femoral artery from the surface of the skin, 2 cm below the mid-inguinal ligament
Dthorax Aortic diameter (at the middle of the thorax)   
Drenal Aortic diameter (at a renal level)   
Dbifurc Aortic diameter (bifurcation level)
