The introduction of the ROSA stereotactic robot offers an image guided stereotactic approach with greater precision and accuracy than traditional frame-based and frameless methods. While the ROSA has never been used for the placement of intra-hemorrhage catheters, prior applications such as brain biopsies and abscess drainage represent similar surgical procedures which require the same planning, precision, and surgical technique. At the very least, ROSA offers an accurate image guided approach to deep lesions that should be comparable to competitive image guided platforms. At best, ROSA offers superior trajectory planning software, greater ease in planning multiple trajectories to large, irregular clots, and the potential for robot aided navigation into and out of the hematoma which is the greatest source of human error in these cases. For instance, the procedure often requires advancement of a larger aspiration catheter, slow aspiration as the catheter is withdrawn, and then re-advancement of a smaller catheter into the hematoma, which is left in place. The ability to advance and remove catheters in a fixed trajectory with robotic assistance may represent the greatest advantage of ROSA.
