Robot-guided stereotactic single-stage evacuation of six intracranial abscesses: a rare case report with literature review
Robot-guided surgery drains six brain abscesses in a single operation
Neurosurgeons in China successfully used a robotic stereotactic system to drain six brain abscesses in a single operation, avoiding repeated procedures or large open craniotomy. The case, published in the Chinese Neurosurgical Journal, describes the use of the Sinovation Robot with SinoPlan planning software to create a 3D model of the abscesses and plan precise needle trajectories. The procedure involved four puncture paths, with robotic assistance ensuring accurate and minimally invasive drainage. Postoperative imaging confirmed successful removal, and the patient achieved full functional recovery. The authors emphasize the potential of robotic techniques for complex intracranial infections but note the need for larger studies to validate their effectiveness.

The paper presents a case study of robot-assisted stereotactic aspiration for multiple brain abscesses, highlighting the use of robotic systems for precise, single-stage evacuation. It contrasts robotic techniques with traditional methods, noting advantages in trajectory planning and reduced invasiveness, while also acknowledging limitations such as registration errors and cost barriers.

One month after surgery, MRI showed complete disappearance of the abscesses, with the abscess walls almo
