Accuracy of tunnelated vs. bolt-connected external ventricular drains.

摘要: Abstract Background Ventriculostomy is one of the most common neurosurgical procedures and an important tool in treatment monitoring elevated intracranial pressure. Low accuracy has frequently been reported literature with risk drain misplacement over 20% a need for reinsertion up to 40%. As alternative tunnelated EVD technique we often use bolt-connected EVD. The aim present study was investigate whether EVDs would lead higher accuracy, fewer passes reoperations due poor placement compared EVDs. Patients methods We retrospectively identified all patients who received from January 1st 2008 December 31st 2010. Postoperative images were evaluated anatomical EVD-tip, distance tip optimal categorized as optimal, suboptimal undesired. Patient files technique, number postoperative complications handling. Results 147 154 separate met inclusion criteria. found statistical significant bolt-group tunnelated-group ( p  = 0.023). Eleven reoperated following ventriculostomy 11.9% reduction  = 0.006). Conclusions have showed this that by using maintaining freehanded can significantly increase precision decrease placement.
