【摘要】：目的：探討3D-CTA在顱內(nèi)腫瘤的應(yīng)用及對手術(shù)方案的指導(dǎo)意義。 方法：收集2013年1月—2013年10月術(shù)前診斷“顱內(nèi)腫瘤”并住院經(jīng)手術(shù)治療和病理證實的患者31例（術(shù)前均行磁共振掃描及3D-CTA檢查且資料齊全）。其中腦膜瘤：16例；膠質(zhì)瘤：7例；神經(jīng)鞘瘤5例；血管母細(xì)胞瘤2例；脂肪瘤1例；女性共17例，男性共14例；年齡在33～66歲之間，平均年齡42.6歲。術(shù)前經(jīng)全科醫(yī)生討論后根據(jù)影像學(xué)圖像指導(dǎo)手術(shù)方案。 結(jié)果：1、3D-CTA可清楚顯示顱內(nèi)腫瘤的大小及血供情況。2、腫瘤與周圍大血管的關(guān)系：術(shù)前發(fā)現(xiàn)腫瘤侵蝕大血管11例，術(shù)中見腫瘤與血管粘連嚴(yán)重，部分腫瘤無法與血管分離；術(shù)前發(fā)現(xiàn)腫瘤推擠大血管20例，術(shù)中可將血管從腫瘤上分離。 結(jié)論：3D-CTA是一種新興的檢查手段，能夠清晰、準(zhǔn)確地顯示腫瘤的立體結(jié)構(gòu)、供血動脈及周圍大血管，能為顱內(nèi)腫瘤的手術(shù)治療提供直觀、科學(xué)、翔實的影像學(xué)資料，指導(dǎo)制定手術(shù)方案，，這可使術(shù)者在術(shù)前判斷手術(shù)的難度，預(yù)測手術(shù)風(fēng)險，預(yù)計術(shù)中出血情況進(jìn)行術(shù)前備血，減少手術(shù)的盲目性，提高手術(shù)的安全性。是顱內(nèi)腫瘤術(shù)前評估中非常有價值的影像學(xué)檢查方法。
[Abstract]:Objective: to investigate the application of 3D-CTA in intracranial tumors and its guiding significance for surgical scheme. Methods: from January 2013 to October 2013, 31 patients with intracranial tumors were diagnosed before operation and confirmed by operation and pathology (MRI and 3D-CTA were performed before operation and with complete data). There were 16 cases of meningioma, 7 cases of glioma, 5 cases of schwannoma, 2 cases of angioblastoma, 1 case of lipoma, 17 cases of female and 14 cases of male, aged between 33 years and 66 years, with an average age of 42.6 years. The surgical plan was guided by imaging images after discussion by the general practitioner before operation. Results: 1, 3D CTA could clearly show the size and blood supply of intracranial tumors. 2, the relationship between tumors and surrounding macrovessels: 11 cases were found to erode macrovessels before operation, and serious adhesion between tumors and blood vessels was found during operation, and some tumors could not be separated from blood vessels. It was found that the tumor pushed and squeezed the large blood vessel in 20 cases before operation, and the blood vessel could be separated from the tumor during operation. Conclusion: 3D-CTA is a new examination method, which can clearly and accurately display the stereoscopic structure of the tumor, the blood supply artery and the surrounding large blood vessels, and can provide intuitive, scientific and detailed imaging data for the surgical treatment of intracranial tumors. Guiding the formulation of surgical plan can make the operator judge the difficulty of operation before operation, predict the risk of operation, predict the bleeding condition before operation, reduce the blindness of operation and improve the safety of operation. It is a very valuable imaging method in preoperative evaluation of intracranial tumors.
