Influence of Formation and Morphometry of the Inferior Vena Cava in the Use of Antithrombotic Devices
The formation level of the inferior vena cava in the vertebral column was found to be at the level of L3 -L4 and L5 - S1, with differences between genders. The total length of the inferior vena cava ranged between 187.10 and 278.3 mm. Interiliac angle measured 48.40 and 85.80o. The length of the IVC from its formation point up to the termination of the right renal vein in the IVC ranged between 78.50 and 135.0mm, and the length of the IVC from its formation point to the termination of the left renal vein into the IVC ranged between 89.80 and 119.0mm. The length of the IVC from its formation up to the termination of the hepatic veins ranged between 197.20 and 263.70mm. The diameter of IVC at the point of its formation ranged between 18.0 and 26.20 mm, at the level of the right infrarenal level ranged between 20.10 and 28.70 mm, in 78.08% of the cases. In female cases, the diameter ranged between 18.06 and 25.69 mm, the diameter of the IVC at the level of the right suprarenal ranged between 19.82 and 31.09mm, the diameter at the level of the left infrarenal ranged between 18.59 and 32.49mm, at the level of the left suprarenal vein ranged between 19.10 and 33,80 mm, the diameter at the intrahepatic level ranged between 20.30 and 33.40mm, and the diameter of the IVC at the suprahepatic level ranged between 23.10 and 37.0mm.
