Application of 3D-computed tomography angiography technology in large meningioma resection.
OBJECTIVE
To discuss the role of 3D-computed tomography angiography (3D-CTA) technology in reducing injuries of large meningioma surgery.


METHODS
3D-CTA preoperative examinations were done in 473 patients with large meningioma (simulated group). The images were analyzed by 3D post-processing workstation. By observing the major intracranial blood vessels, venous sinus, and the compression and invasion pattern in the nerve region, assessing risk level of the surgery, simulating the surgical procedures, the surgical removal plan, surgical routes and tumor blood-supplying artery embolisation plan were performed. Two hundred and fifty seven large meningioma patients who didn't underwent 3D-CTA preoperative examination served as control group. The incidence of postoperative complications, intraoperative blood transfusion and the operation time were compared between these two groups.


RESULTS
Compared with the control group, the Simpson's grade I and II resection rate was 80.3% (380/473), similar with that of the control (81.3%, 209/257). The incidence of postoperative complications in 3D-CTA simulated group was 37.0% which was significantly lower than that (48.2%) of the control (P<0.01). The intraoperative blood supply for simulated group and the control was (523.4±208.1) mL and (592.0±263.3) mL, respectively, with significant difference between two groups (P<0.01). And the operation time [(314.8±106.3)] min was significantly lower in simulated group than that in the control [(358.4±147.9) min] (P<0.01).


CONCLUSIONS
Application of 3D-CTA imaging technology in risk level assessment before large-scaled meningioma resection could assist in the rational planning of tumor resectin, surgical routes, and is helpful in reducing injuries and complications and enhancing the prognosis of the patients.
