Objective:
To explore the practicability of resecting small lesions in deep brain by intraoperative magnetic resonance imaging (iMRI) and neuronavigator-assisted microsurgery and its clinical efficacies.
Methods:
A total of 42 cases with small lesions in deep brain underwent intraoperative MRI and neuronavigator-assisted microsurgery. The drifting of neuronavigation was corrected by images acquired from intraoperative MR rescanning.
Results:
All lesions were successfully identified and 40 cases totally removed without mortality. Only 3 cases developed new neurological deficits post-operatively while 2 of them returned to normal neurological functions after a follow-up duration of 3 months to 2 years.
Conclusion:
The application of intraoperative MRI can effectively correct the drifting of neuronavigation and enhance the accuracy of microsurgical neuronavigation for small lesions in deep brain.
Insights
Intraoperative MRI combined with neuronavigator-assisted microsurgery effectively resects deep brain lesions. This technique improves navigation accuracy and patient outcomes for small brain tumors.
Area of Science:
- Neurosurgery
- Medical Imaging
Context:
- Deep brain lesions present surgical challenges due to location.
- Accurate navigation is crucial for safe and effective resection of small lesions.
Purpose:
- To evaluate the feasibility and clinical efficacy of using intraoperative magnetic resonance imaging (iMRI) with neuronavigator-assisted microsurgery for deep brain lesions.
- To assess the impact of iMRI on surgical accuracy and patient outcomes.
Summary:
- 42 patients with small deep brain lesions underwent iMRI and neuronavigator-assisted microsurgery.
- Neuronavigation accuracy was maintained by correcting drift with iMRI.
- Complete resection was achieved in 40 cases with no mortality; only 3 patients had transient neurological deficits.
Impact:
- This combined approach enhances the precision of microsurgery for deep brain lesions.
- Intraoperative MRI is a valuable tool for improving surgical navigation accuracy.
- The technique demonstrates significant clinical efficacy and safety in managing small deep brain lesions.
