Evaluation of external ventricular drain complications and the use of a procedure-targeted image-guidance system
… Hospital (BWH) to characterize the practice of external ventricular drain placements using data from the patient electronic medical record. Post-procedure catheter location was measured on post-procedure CT and MRI imaging studies. Most cases were performed in the operating room and the …

Evaluating Human Performance for Image-Guided Surgical Tasks
… biopsy tasks using a tracked biopsy device, and external ventricular drain placement tasks using a mobile-based augmented reality device for visualization and guidance. In both tasks, a human performance methodology was utilized which respects the trade-off between speed and accuracy for users …

Spontaneous Angiogram Negative Subarachnoid Hemorrhage : A Retrospective Single Center Cohort Study
… hydrocephalus, 28% were acutely treated with an external ventricular drain, 13% received active vasospasm treatment and 17% received a permanent shunt. In the multivariable logistic regression model, only acute hydrocephalus associated with unfavorable outcome (odds ratio 4.05, 95% confidence …

The Groote Schuur Hospital Neurosurgical Intensive Care Unit: A 2 Year Experience
… tissue oxygenation monitor (19.3%), 86 had an external ventricular drain placed (12.5%), 50 patients required placement of a tracheostomy (7.3%) and 16 patients had only an ICP monitor placed (2.3%). The average duration of stay was 5.5 (±1.3) days and ICU mortality over 2 years was 11.1%. …

The management of post-infectious hydrocephalus in people living with HIV: a prospective observational study
… groups, surgical (ventriculoperitoneal shunts/ external ventricular drain) and medical (lumbar spinal taps) based on institutional practice. Results PIH aetiologies were noted as tuberculous in 78.3% (n=18) and cryptococcal in 21.7% (n=5). Overall survival at discharge was 69,9% (n=16) and 47.8% …

Safe anatomy-driven tracking for navigation and robotics in medical and surgical procedures
… neurosurgical navigation system for external ventricular drain (EVD) placement. Using a novel skull-mounting mechanism, the device provides forward-kinematic tracking of neurosurgical instruments, eliminating the need for traditional infrastructure-intensive tracking systems and …

Surgical site infections in Neurosurgery
… wounds had the highest risk for SSI (8,7%) with external ventricular drain (EVD) insertion carrying the highest risk in clean operations (6,5%). Age was a risk factor for superficial SSI, while operative time and cerebro-spinal fluid (CSF) leak were risk factors for deep infection. 36,4% of SSI …

Entry-based Planning of Neurosurgical Trajectories
… In cases of brain trauma or hydrocephalus an external ventricular drain (EVD) is often inserted through the skull and brain to drain excess cerebrospinal fluid from the ventricles to relieve pressure. Most often, EVDs are inserted free-hand, without guidance, at a point on the skull named …

Development, Validation, and Testing of a Sonification Framework with a Neurosurgical Targeting Task
VR applications in medicine offer high potential for cost-savings and accessible educational modalities. Sonification, the use of non-speech audio to convey information, is also increasingly complex and viable for commercial applications. Together, these technologies can be leveraged to improve …
