Abstract

To introduce a new device for catheter placement of an external ventricular drain (EVD) of cerebrospinal fluid (CSF). This device was composed of three portions, T-shaped main body, rectangular pillar having a central hole to insert a catheter and an arm pointing the tragus. The main body has a role to direct a ventricular catheter toward the right or left inner canthus and has a shallow longitudinal opening to connect the rectangular pillar. The arm pointing the tragus is controlled by back and forth movement and turn of the pillar attached to the main body. Between April 2012 and December 2014, 57 emergency EVDs were performed in 52 patients using this device in the operating room. Catheter tip located in the frontal horn in 52 (91.2%), 3rd ventricle in 2 (3.5%) and in the wall of the frontal horn of the lateral ventricle in 3 EVDs (5.2%). Small hemorrhage along to catheter tract occurred in 1 EVD. CSF was well drained through the all EVD catheters. The accuracy of the catheter position and direction using this device were 91% and 100%, respectively. This device for EVD guides to provide an accurate position of catheter tip safely and easily.

  Fig. 1 A : Device for external ventricular drain (EVD). T-shaped main body, screw, rectangular pillar having a longitudinal central hole, an arm pointing the tragus and EVD catheter are visible. Both tips of vertical portion of the main body has a role to direct a ventricular catheter toward the right and left inner canthi, respectively. Horizontal portion has a shallow longitudinal opening to connect the rectangular pillar and move it back and forth. B and C : EVD procedures in dummy, respectively. Arrows indicate medial canthus and tragus in both hemispheres.
