ABSTRACT
Objective:
To explore the application value of electromagnetic navigation technique in the removal of hematoma under neuroendoscope.Methods:
Forty-three patients with supratentorial spontaneous cerebral hemorrhage, accepted removal of hematoma under neuroendoscope in our hospital from October 2015 to February 2019, were chosen in our study; 22 patients (navigation group) were performed the removal under the guide of real-time electromagnetic navigation, and 21 (non-navigation group) were performed the removal under neuroendoscope only. The amount of cerebral hemorrhage, operation time, residual amount of hematoma and hematoma clearance rate were compared between the two groups. Fugl-Meyer Assessment (FMA) was used to evaluate the motor function of the affected limbs two weeks after surgery. The anisotropy fraction (FA) values of fibers of affected pyramidal tracts and contralateral pyramidal tracts were examined by diffusion tensor imaging (DTI), and the relative FA (rFA) value (FA values of affected side/contralateral side) was calculated. Barthel index was used to evaluate the basic daily activities of the patients 6 months after surgery.Results:
There was no significant difference between the navigation group and the non-navigation group in the amount of cerebral hemorrhage before surgery, amount of residual hematoma after surgery, hematoma clearance rate, and operation time ( P>0.05). FMA scores of upper and lower limbs, FA and rFA values of the affected side in the navigation group were significantly higher than those in the non-navigation group two weeks after surgery ( P<0.05). Barthel index of patients in the navigation group was statistically higher than that of the non-navigation group 6 months after surgery ( P<0.05).Conclusion:
Electromagnetic navigation technique can guide endoscopy to effectively clear the supratentorial hypertensive cerebral hemorrhage without obviously increasing the operation time; effective protection of pyramidal fibers can improve the prognoses of patients.
