Hemorrhagic complications after removal of an external ventricular drain: A case report and literature review.

Background: External ventricular drainage (EVD) is one of the most common neurosurgical procedures. Complications are rather rare and mostly include hemorrhage and infection. Hematomas may form during placement or even after the removal of an EVD. Regarding the latter, the literature is scarce, with only nine clinically significant cases reported. Case Description: We present the case of a young woman who suffered an extensive hemorrhage after removal of an EVD, in the setting of a posterior fossa stroke. We discuss the management and possible consequences of such an event and we emphasize the need for alertness to avoid such complications. Conclusion: Removal of an EVD is a safe procedure, with rare cases of hemorrhagic complications being reported. A case of a large hematoma that formed after the removal of an EVD is presented. Stricter follow-up protocols should be implemented to better estimate the risk of hemorrhage.
