Application Of3D-CTA In Intracranial Tumour And Guiding Significance In Its Operation

Objective: To discuss the application of3D-CTA in intracranial tumour andformulation and guidance significance of operation scheme.Methods: Collect31patients with “intracranial tumour” according to thepreoperative diagnosis and hospitalized with operative treatment and pathologicalconfirmation between Jan.2013and Oct.2013(NMR and3D-CTA examinationconducted before operation with all materials), of which there are16cases withmeningioma;7with glioma,5with schwannoma,2with hemangioblastoma,1withlipoma17females and14males, aged from33to66years old, averagely aged42.6years old. Operative approach is taken after discussion of general medicalpractitioners before operation according to imaging design.Results: Firstly,3D-CTA could distinctly reveal the size and blood supply ofintracranial tumour. Secondly, the relationship between tumour and peripheral greatvessels: it is found that there are11cases with great vessels eroded by the tumourbefore operation; the tumour is severely adhered to the vessels during operation andthe tumour can not be separated with the vessels. It is found that there are20caseswith the great vessels pushed by the tumour and the vessels can be separated from thetumour during operation. The assistance can be given in formulating operationscheme by being familiar with the relationship between the tumour and peripheralvessels.Conclusion:3D-CTA, a burgeoning examination method, could distinctly andaccurately reveal stereochemical structure, feeding artery, peripheral great vessel,selection of preoperative approach and design of skull flap and also could provideintuitive, scientific, accurate and complete imaging data for operative treatment ofintracranial tumour and enhance the safety of operation. It is also a very valuableimagining examination method for preoperative assessment of intracranial tumour.
