Abstract
BACKGROUND
Large supratentorial intraparenchymal hemorrhages are managed emergently with image-guided catheters that aim to minimize injury to surrounding parenchyma. Robotic assistance may offer advantages for stereotactic guidance and placement of such catheters. We describe our center's experience with minimally invasive ROSA-assisted intraventricular and intraparenchymal hemorrhage catheter placement and delineate its safety and outcomes.
METHODS
A retrospective analysis was performed including all patients with intraparenchymal hematoma that underwent ROSA-assisted intraparenchymal and intraventricular catheter placement at the University of Pittsburgh Medical Center between 2017 and 2019. All patients received tissue plasminogen activator (tPA) through the intraparenchymal catheter. We performed a manual chart review of these patients. Pertinent clinical and radiological characteristics and patient outcomes were recorded and analyzed. Catheter trajectory was independently quantified and analyzed by two independent reviewers. Error between the planned trajectory and final position was calculated and analyzed.
RESULTS
Four patients (2 males and 2 females, mean age of 64 years) with deep brain large volume intraparenchymal hemorrhages were treated with catheter evacuation with robotic assistance. For 2 of the 4 patients, thin-cut CT imaging allowed for the real trajectory of the catheter to be compared to the targeted trajectory to calculate error. The mean error of catheter placement was 3.48 mm. ROSA-assisted catheter placement achieved up to 95% reduction of intraparenchymal hematoma volume with a statistically significant decrease following catheter drainage (pre- 51.8 ± 19.1 cc vs. post- 13.0 ± 14.4; p < 0.01).
CONCLUSION
Robotic stereotactic assistance offers a safe and sufficiently accurate technique for intraparenchymal hematoma and intraventricular catheter placement.
