Percutaneous computed tomographic-controlled ventriculostomy in severe traumatic brain injury

Percutaneous computed tomographic (CT)-controlled ventriculostomy (PCV) was introduced for the monitoring of intracranial pressure in patients with severe traumatic brain injury who did not require simultaneous decompressive trepanation.

PCV (n = 14) was compared with conventional burr hole ventriculostomy (n = 13) based on prospectively collected data.

PCV proved to be a successful technique in all cases and also when a burr hole ventriculostomy was impossible previously. There were no complications. In burr hole ventriculostomy, there were one unsuccessful insertion and one catheter contamination. The main advantage of PCV over burr hole ventriculostomy was a significant (p < 0.05) reduction in the time required to perform the procedure. In ventriculostomy directly after the initial evaluation in the emergency department, the operation time was reduced from 45 +/- 11 to 22 +/- 14 minutes. The interval between cranial computed tomography and start of operation was reduced from 78 +/- 38 to 33 +/- 12 minutes, and between initial cranial computed tomography and intensive care unit admittance, from 138 +/- 37 to 73 +/- 28 minutes. For patients requiring ventriculostomy while being treated in the intensive care unit, the duration of the procedure (i.e., absence from the intensive care unit) was able to be reduced from 111 +/- 24 to 81 +/- 21 minutes.

Distinct time savings are the major advantages of PCV, allowing exact catheter positioning even with very narrow ventricles.
