External Ventricular Drainage and Hemorrhage



An interesting study comes from Dr. Gardner et al. at the Department of Neurological Surgery, University of Pittsburgh, Pennsylvania. The external ventricular drainage placement is a common practice in everyday neurosurgical activity but the complications relying on hemorrhage were not clearly depicted. This study involving 188 EVD placements tries to quantify and qualify the extent of this complication and interestingly 41% of the patients showed imaging evidence of hemorrhage. Most of the hemorrhages were  of insignificant value (punctuate, trace SAH, or small volume) while 10.6% of the patients had >15ml hemorrhage or associated IVH. The study concludes that there is an increased risk concerning EVD placement and hemorrhage but rarely a surgical intervention is needed. There was no significant risk reduction when the placement was done in the OR or the NICU.
