Anatomic Consideration in Placement of Central Venous Catheters: A Cadaveric Study: Comparison of Supraclavicular Anterior and Posterior Internal Jugular Venous Approach

A comparison of Central venous catheterization (CVC) of the superior vena cava via the anterior and posterior internal jugular venous approach was done. Anterior approach required insertion of needle into the apex of Sedillot's triangle, The distances from the apex of Sedillot's triangle to the ipsilateral sternoclavicular joint was also measured. For posterior approach needle was inserted at a point one-third of the distance along the line between the sternal head of the clavicle and the mastoid process, just lateral to SCI VI. Subsequently the area was dissected to note the position of needle Results indicate that on the right, the needle was inserted into the IN in 93.75% & 87.50% of the cases in anterior and posterior approach respectively, whereas on the left, the needle entered the IN in 75.00% of the cases in both approaches. Distance between sternoclavicular joint and apex of Sedillot's triangle was 42.56 ± 8.47mm & 40.94 ± 11.65mm on the right and left, respectively. It was concluded that the anterior IN approach is better technique with success more on the right side.
