[Image-guided microsurgery in resection of intracranial cavernous hemangioma].
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.


CONCLUSIONS
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.
