Summary
Free-hand needle procedures guided by CT scans are effective for brain lesion biopsy and drainage. These minimally invasive techniques offer low morbidity and mortality, proving valuable in neurosurgery.
Area of Science:
- Neurosurgery
- Medical Imaging
- Interventional Radiology
Background:
- Brain lesions require accurate diagnosis and management.
- Minimally invasive techniques are preferred for reducing patient risk.
- Computed Tomography (CT) provides precise anatomical visualization.
Purpose of the Study:
- To evaluate the efficacy and safety of free-hand needle procedures using CT guidance.
- To assess the utility of CT-guided biopsy and drainage for various brain lesions.
- To compare these techniques with more complex neurosurgical approaches.
Main Methods:
- A retrospective analysis of 184 procedures performed on 120 patients over 20 years.
- Procedures included CT-guided biopsy of suspected neoplasms (60 cases).
- CT-guided drainage was performed for intracerebral hemorrhage (40 cases) and intracranial suppuration (20 cases).
Main Results:
- Low rates of morbidity and mortality were observed.
- Effective management achieved through steroid therapy, prophylactic antibiotics, and sterile technique.
- A single complication of postoperative hemorrhage occurred in a patient with metastatic melanoma.
Conclusions:
- Free-hand CT-guided needle procedures are simple, accurate, and widely applicable in neurosurgery.
- These techniques demonstrate favorable outcomes compared to methods requiring stereotactic frames or intraoperative monitoring.
- The study supports the continued use of these established, effective neurosurgical techniques.
