Objective:
To study the methods and effectiveness of image-guided microsurgery in resection of intracranial cavernous hemangioma.
Methods:
Between July 1997 and January 2001, 44 patients with intracranial cavernous hemangioma, 27 males and 17 females with a mean age of 35 years, among which 5 cases had multiple lesions, underwent image-guided microsurgery. The locations of lesions included frontal lobe (n = 14), temporal lobe (n = 12), parietal lobe (n = 6), cerebellum (n = 6), thalamus (n = 5), pons (n = 5), and orbital lobe (n = 1). A small silicon catheter, used as a guider, was implanted to the deep-seated lesion (except the brain stem lesions) before excision of the lesion in order to prevent brain shift.
Results:
Total removal of the lesions was achieved in all patients without operational death. Follow-up revealed marked improvement of symptoms in 26 case and no change of symptom(s) in 13 cases. 5 cases suffered from additional neurological deficits, mainly exacerbation of hemiparalysis and aphasia, the condition of two of which, however, gradually improved within the period of follow-up. No residue of lesion and relapse were found during follow up.
Conclusion:
With the assistance of the image-guided surgical system, functional area can be effectively avoided, and surgical injury can be decreased. It is well suited for accurate localization and safe resection of small, deep-seated cavernous malformations.
Insights
Image-guided microsurgery effectively resects intracranial cavernous hemangiomas, improving patient outcomes. This technique minimizes surgical injury and aids in precise localization of deep-seated lesions.
Area of Science:
- Neurosurgery
- Medical Imaging
- Neurology
Context:
- Intracranial cavernous hemangiomas pose surgical challenges due to their location.
- Accurate localization and safe resection are critical for favorable patient outcomes.
Purpose:
- To evaluate the methods and effectiveness of image-guided microsurgery for intracranial cavernous hemangioma resection.
- To assess the safety and efficacy of this surgical approach.
Summary:
- 44 patients underwent image-guided microsurgery for intracranial cavernous hemangiomas.
- Total lesion removal was achieved in all cases with no operative mortality.
- Postoperative follow-up showed symptom improvement in most patients, with no residual lesions or relapses.
Impact:
- Image-guided surgery allows for effective avoidance of functional areas and reduced surgical injury.
- This technique is well-suited for the accurate localization and safe resection of small, deep-seated cavernous malformations.
