Meta Analysis
Meta-analysis of hemorrhagic complications from ventriculostomy placement by neurosurgeons.
Ventriculostomy placement is an important diagnostic and therapeutic tool for neurosurgeons. Multiple authors have presented retrospective series of patients evaluating periprocedure hemorrhage. ⋯ Based on our meta-analysis, the overall hemorrhagic complication rate from ventriculostomy placement by neurosurgeons is approximately 7%. The rate of significant hemorrhage from ventriculostomy placement is approximately 0.8%. Further prospective studies are warranted to better address this question.

Multicenter Study
Subarachnoid hemorrhage patients' fears of recurrence are related to the presence of posttraumatic stress disorder.
Subarachnoid hemorrhage (SAH) patients illustrate a chronic fear of recurrence. A third of patients develop posttraumatic stress disorder (PTSD) after SAH, and PTSD after other conditions is associated with a more negative outlook on life. ⋯ Fear of recurrence after SAH is related to PTSD. Participants with PTSD were more pessimistic about their future health. Treatment for PTSD could alleviate fears of SAH recurrence and promote better outcome.

Low blood flow velocity in the middle cerebral artery (MCA) correlates with the development of postoperative cerebral ischemic lesions related to generation of microemboli during dissection of carotid arteries in carotid endarterectomy (CEA). ⋯ Increased MCA mean blood flow velocity by intentional hypertension during dissection of the carotid artery in CEA prevents the postoperative development of new cerebral ischemic lesions caused by intraoperative microemboli.

Deep brain stimulation (DBS) at the subthalamic nucleus (STN) is an effective treatment for the motor manifestations of advanced medically refractory Parkinson disease. Because of the medial location of the target, surgical trajectories to the STN may violate the ipsilateral lateral ventricle. ⋯ Violating the ventricular system during STN DBS surgery correlated significantly with postoperative altered mental status and subsequent increased length of hospital stay. This finding may explain why cognitive complications are observed more frequently in Parkinson disease patients undergoing DBS at the STN compared with the internal globus pallidus.
