“…Contamination of the ventricular catheter at the scalp tract overlying the drill site is thus a potentially important source of infections. With skin incision in the smallest possible level, subcutaneous tissue and the ventricular catheter parts fewer contact with the flora and primarily to prevent infection may be as many complications [12][13][14][15][16][17][18][19][20][21].…”

Objective: In this study we aimed to determine a landmark that can be measured through the skin with nasal mid-point (bregma) to coronal suture, and additionally an average value was calculated. We report, to our knowledge, the distance between the nasion-coronal sutures is reported for the first time in Turkish population. Methods:The study included 30 craniums and 30 frontal bones. Each skull from midline nasal suture to coronal suture curved up at the distance was measured with tape measure. Results:Mean values were determined. Nasal suture between coronal suture distance average 12,2 cm (min10,3 cm, up to 13,5 cm) were detected. Conclusion:Nasal suture is an easily palpable area through the skin. A small incision is carried down through skin to bone at the spot 12 cm back from the nasion 3 cm lateral to the midline for ventricular drainage operation. This data provide practical information for neurosurgeon and is available everywhere. J Clin Exp Invest 2014; 5 (3): 368-370

“…Lin et al's 58 ventricular catheter, marketed as the Rivulet catheter by Medtronic, was designed so that the hole diameter gradually decreased away from the tip to increase resistance to flow in the smaller-diameter holes where a majority of flow occurs. 57,127 If flow is resisted, the quantity of proteinand cell-laden CSF may be diminished and therefore less likely to occlude, but this relationship has not been studied to date. The other study was done by our group and differed slightly in data interpretation.…”

The treatment of hydrocephalus by cerebrospinal fluid shunting is plagued by ventricular catheter obstruction. Shunts can become obstructed by cells originating from tissue normal to the brain or by pathological cells in the cerebrospinal fluid for a variety of reasons. In this review, the authors examine ventricular catheter obstruction and identify some of the modifications to the ventricular catheter that may alter the mechanical and chemical cues involved in obstruction, including alterations to the surgical strategy, modifications to the chemical surface of the catheter, and changes to the catheter architecture. It is likely a combination of catheter modifications that will improve the treatment of hydrocephalus by prolonging the life of ventricular catheters to improve patient outcome.

“…If present, an additional arachnoid membrane-Liliquist's membrane-was opened similarly to establish unobstructed CSF passage from the third ventricle into the prepontine cistern. Under endoscopic view, a catheter (6 hole, Miethke, Potsdam, Germany) [34] with additional 3 to 4 proximal openings was advanced parallel to the optic unit of the endoscope until its tip came into view and then inserted through the fenestration into the prepontine cistern. The optical unit was retracted, and the position of the additional proximal perforations in the catheter within the lateral ventricle was confirmed.…”
