发布时间：2018-12-16 18:43
【摘要】：目的探讨虚拟现实(Virtual reality,VR)技术观察颅内窦汇(Torcular herophili,TH)区解剖及变异的价值。方法对45例未累及TH区结构的颅内脑膜瘤患者,以及21例三叉神经痛或面肌痉挛患者,行3D CE-MRV检查,再在VR工作站重建TH,观察其构成及引流特点。结果根据上矢状窦(Superior sagittal sinus,SSS)、直窦(Straight sinus,StS)和双侧横窦(Transverse sinus,TS)的吻合关系,TH区VR解剖形态分为3型:Ⅰ型18例,Ⅱ型15例,Ⅲ型33例。根据SSS汇入TS的方式分为4型:Ⅰ型18例,Ⅱ型26例,Ⅲ型17例,Ⅳ型5例。根据StS汇入TS的方式分为4型:Ⅰ型18例,Ⅱ型23例,Ⅲ型7例,Ⅳ型18例。TS引流优势表现为右侧为主25例,左侧为主9例,基本相等32例。结论 TH区解剖变异性较大,VR技术是观察TH区解剖的有效方法,有助于了解TH区的解剖和引流特点,对临床诊断及TH区手术有指导意义。
[Abstract]:Objective to investigate the value of virtual reality (Virtual reality,VR) technique in the anatomy and variation of intracranial sinus confluence (Torcular herophili,TH). Methods 45 patients with intracranial meningioma without involvement of TH structure and 21 patients with trigeminal neuralgia or hemifacial spasm were examined by 3D CE-MRV. The composition and drainage characteristics were observed by TH, reconstruction on VR workstation. Results according to the anastomosis of superior sagittal sinus (Superior sagittal sinus,SSS), straight sinus (Straight sinus,StS) and bilateral transverse sinus (Transverse sinus,TS), the anatomic morphology of VR in TH region was divided into three types: type 鈪，
