Abstract：Objective To explore the value of the three-dimensional dual-sources CT angiography (3D-DS-CTA) to preoperative assessment of meningiomas. Methods A retrospective analysis of the clinical data of 26 patients with skull base or parasigittal meningiomas, who received 3D-DS-CTA examination before the surgery in order to estimate the tumors with the blood vessels of skull base or sagittal sinus, was made. Results The relationships of the meningioma with peripheral vessels and venous sinus which were clearly shown by 3D-DS-CTA were consistent with intraoperative findings in all the patients. Of 26 patients, 16 received Simpson gradeⅡresection of the tumors, 5 Simpson gradeⅢand 4 Simpson gradeⅣ. The blood vessels were protected well during the surgery. No postoperative complications including cerebral infarction and cerebral hemorrhage occurred in all the patients. The Karnofsky score after the surgery increased by 20 points compared with the preoperative one. The following up from 6 to 24 months showed that no tumors recurred in 22 patients and the tumors recurred in 4 patients who underwent surgery again. Conclusion The preoperative 3D-DS-CTA examination is of important value to the surgery for the skull base or parasigittal meningiomas because it can clearly show the relationship of the meningiomas with peripheral vessels and venous sinuses which is helpful to the intraoperative protection of the peripheral vessels.
