Abstract:
Objective To evaluate the clinical value of 320-row CT angiography (CTA) in the microsurgery of parasagittal meningiomas. Methods Thirty-eight patients with parasagittal meningiomas, admitted to our hospital from May 2008 to August 2010 and confirmed by CT and MR1,were examined with the 320-row CTA to observe the relations between tumor blood vessels and brain vessels, and between the tumor and the skull. Results The 320-row CTA provided clear three-dimensional images of the meningioma and its relations with the adjacent vessels and the skull. The condition of blood flow in the parasagittal sinus was shown and the proper surgical approach to remove the neoplasm was demonstrated. Simpson graded Ⅰ and Ⅱ resection was achieved in 26 and 12 patients,respectively. All the patients recovered well without postoperative deaths. Temporary paralysis or aggravated paralysis was noted in 8 after the operation and 5 of them recovered. Conclusion The 320-row CTA, being able to provide images of the parasagittal meningioma, and demonstrating its relations with the skull, adjacent vessels and sagittal sinus, can supply the vital information to choose the proper surgical approach and provide the useful message to manage the sinus during the operation, which has a great value in preoperative evaluation of the parasagittal meningioma.
