Summary
This study demonstrates CT-guided stereotaxic biopsy is a safe and effective method for brain tumor diagnosis. The technique accurately guides biopsy needles, ensuring tissue samples correlate with CT findings without complications.
Area of Science:
- Neurosurgery
- Neuroradiology
- Oncology
Background:
- Accurate tissue diagnosis is crucial for effective brain tumor management.
- CT-guided stereotaxy offers precise localization for neurosurgical interventions.
Purpose of the Study:
- To evaluate the efficacy and safety of CT-guided stereotactic biopsy for brain tumors.
- To assess the correlation between biopsy findings and CT imaging.
Main Methods:
- Performed CT-guided stereotactic biopsy on 13 brain tumor cases using Leksell's system and Hitachi W-3 scanner.
- Utilized stepwise biopsies with a spiral needle, with needle trajectory visualized by CT.
- Varied trepanation sites and needle insertion angles based on tumor location.
Main Results:
- No postoperative hematomas or worsening of symptoms were observed in any cases.
- Minimal bleeding occurred in one case, managed successfully with induced hypotension.
- Confirmed accurate needle placement and correlation of tissue samples with CT findings.
Conclusions:
- CT-guided stereotactic biopsy is a safe and effective technique for obtaining brain tumor tissue samples.
- The method allows for reliable correlation between histological diagnosis and imaging.
- This approach minimizes complications and aids in definitive tumor characterization.
