We report a new technique in approaching the cavernous sinus through an occluded inferior petrosal sinus (IPS) using three-dimensional (3D) venography.
A patient diagnosed with arteriovenous fistula of the right cavernous sinus underwent transvenous embolization. The IPS was not detectable on angiogram. Retrograde injection of contrast with 3D imaging of the internal jugular vein clearly demonstrated the remnant of the IPS. By referring to the images obtained, catheterization of the cavernous sinus by way of the IPS was performed without difficulties.
Three-dimensional venography for detecting the entrance to the IPS is a useful method and easy to perform. We believe that this technique should be considered whenever the access to an occluded IPS is necessary.
我们报告一种利用三维(3D)静脉造影术通过闭塞的岩下窦(IPS)进入海绵窦的新技术。
一名被诊断为右侧海绵窦动静脉瘘的患者接受了经静脉栓塞治疗。血管造影未检测到IPS。通过颈内静脉的3D成像逆行注射造影剂清楚地显示了IPS的残余部分。参考所获得的图像,经IPS途径对海绵窦进行插管操作顺利。
用于检测IPS入口的三维静脉造影是一种有用且易于实施的方法。我们认为,每当需要进入闭塞的IPS时,都应考虑采用这种技术。
