Résumé
Using a stereotactic technique, surgeons can accurately place a depth electrode (DE), but sometimes the DE deviates from the intended target due to movement of the electrode or leakage of cerebrospinal fluid when placing the electrode. If DEs can be anchored before removing the catheter insertion guide pipe, more accurate placement may be possible. We made a side slit guide pipe. When the DEs were anchored to the dura or the edge of the burr hole, the DE did not move when the guide pipe was removed. We measured the distance between the planned target and the tip of the electrode in 13 patients (3 female and 10 male patients; age range, 7-43 years; mean age 23.0 years; median age 27 years) with medically intractable epilepsy who underwent DE placement with stereotactic neuronavigation guidance. There were 30 DEs implanted. The mean distance from the planned target to the tip of the DE was 0.570 mm (range, 0.3-1.2 mm; median 0.5 mm; SD 0.212). The mean distance from the planned target to the tip of the DE with dural anchoring was 0.467 mm (range, 0.3-0.6 mm; median 0.45 mm; SD 0.121) and with burr hole edge anchoring was 0.596 mm (range, 0.3-1.2 mm; median 0.50 mm; SD 0.224; P = 0.205). DEs can be anchored using the side slit guide pipe for more precise placement.

METHODS
METHODS
We made a side slit guide pipe. When the DEs were anchored to the dura or the edge of the burr hole, the DE did not move when the guide pipe was removed. We measured the distance between the planned target and the tip of the electrode in 13 patients (3 female and 10 male patients; age range, 7-43 years; mean age 23.0 years; median age 27 years) with medically intractable epilepsy who underwent DE placement with stereotactic neuronavigation guidance.

RESULTS
There were 30 DEs implanted. The mean distance from the planned target to the tip of the DE was 0.570 mm (range, 0.3-1.2 mm; median 0.5 mm; SD 0.212). The mean distance from the planned target to the tip of the DE with dural anchoring was 0.467 mm (range, 0.3-0.6 mm; median 0.45 mm; SD 0.121) and with burr hole edge anchoring was 0.596 mm (range, 0.3-1.2 mm; median 0.50 mm; SD 0.224; P = 0.205).

DEs can be anchored using the side slit guide pipe for more precise placement.
