| Abstract |
Introduction: Stereotactic aspiration is a widely used modality in the treatment of intracranial hematoma (ICH). The vertical approach is used in most stereotactic catheterizations. The catheter enters through the frontal lobe. The running distance of the catheter from the basal ganglia to the hematoma is shorter in the vertical approach than in the transverse approach. In this research, we have investigated further differences between vertical and transverse catheterization.
Materials and Methods: This study is retrospective comparison of hematoma resolution rate between vertical inserted catheter group and transverse inserted catheter group in the stereotactic aspiration of ICH. We retrospectively reviewed operation data and paired the vertical (n=8) and transverse approach (n=8) cases. The mean ages were 59 years old in the transverse group and 61.5years old in the vertical group. The mean operation time was 290 minutes in the transverse group and 288.8 minutes in the vertical group. The paired clinical data were then analyzed in terms of clinical outcome, hematoma resolution rate, and preoperative hemostatic laboratory data.
Results
Age, initial GCS, and hemostatic laboratory findings had no significant difference in both vertical and transverse approach groups. The GCS improvements in each group were not significantly different. On the 14th day following operation, the hematoma volume in the vertical group was 4.38mL and 19.2mL in the transverse group (paired t-test, p=0.042).
Conclusion
In stereotactic catheterization, the vertical approach and transverse approach do not show any different clinical outcomes. However, the vertical approach group reached hematoma resolution more quickly. |
