Overview
Brief Summary
The purpose of this clinical trial is to observe the improvements in clinical symptoms and imaging outcomes for brainstem hemorrhage using robot-assisted stereotactic puncture, evaluate the clinical efficacy and safety of this treatment, and explore the development of a high-precision, intelligent, and individualized microsurgical diagnosis and treatment process for brainstem hemorrhage. The main questions it aims to address are:
- Establish a multi-center clinical database for brainstem hemorrhage.
- Clinically observe and evaluate the intervention effects of robot-assisted stereotactic puncture on brainstem hemorrhage, compare it with the traditional conservative treatment control group, and investigate its efficacy and impact on patient survival, motor evoked potentials, and the degree of neurological deficits.
- Optimize the Artificial Intelligence (AI) algorithm-based robotic surgical assistance system, and explore the prediction of preoperative brainstem hematoma stability and hematoma path planning.
Participants in the experimental group will:
- Undergo robot-assisted stereotactic minimally invasive surgery for brainstem hematoma puncture
- Receive conservative non-surgical treatment.
If there is a control group: the researchers will compare the conservative non-surgical treatment group to evaluate the effectiveness of robot-assisted stereotactic minimally invasive surgery for brainstem hematoma puncture.
