Kocher S Point Evd. 2 5 centimeters from the midline 11 cm posterior to the nasion 3. Direction of canula perpendicular to the cortex and slightly cephalic. This is usually found 10 5 to 11 0 cm back from the nasion and 2 5 to 3 0 cm lateral to the midline which usually corresponds to the mid pupillary line.
It is located 2 5 centimeters from the midline at approximately the mid pupillary line approximately 11 cm posterior to the nasion. Direction of canula perpendicular to the cortex and slightly cephalic. Clip the patient s hair where placement of ventriculostomy will be. 2 5 centimeters from the midline 11 cm posterior to the nasion 3.
Frontal burr hole 2 to 3 cm lateral to mid line and 1 cm anterior to coronal suture in the mid pupilaary line.
Mark the location of kocher s point. This is usually found 10 5 to 11 0 cm back from the nasion and 2 5 to 3 0 cm lateral to the midline which usually corresponds to the mid pupillary line. External ventricular drainage evd ventriculostomy 1. The evd catheter is most frequently placed by way of a twist drill craniostomy placed at kocher s point a location in the frontal bone of the skull with the goal of placing the catheter tip in the frontal horn of the lateral ventricle or in the third ventricle. Direction of canula perpendicular to the cortex and slightly cephalic.
