Abstract:
The superior petrosal sinus and petrosal vein are important drainage routes for the posterior cranial fossa, with some variations and collateral vessels. An anterolateral-type tentorial dural arteriovenous fistula, which occurs around the petrosal vein, often develops aggressive symptoms due to venous reflux to the brainstem and cerebellum. Neuroendovascular treatment of this fistula is usually challenging because transarterial embolization has a high risk and indications for transvenous embolization are limited. In the cavernous sinus and transverse sinus/sigmoid sinus dural arteriovenous fistulas, venous reflux to the petrosal vein is dangerous, and a treatment strategy with the occlusion of the petrosal vein is indispensable. Furthermore, attention should be paid to venous approaches through the superior petrosal sinus.
摘要:
岩上窦和岩静脉是后颅窝重要的引流途径,有一些变化和侧支血管。前外侧型幕膜动静脉瘘,发生在岩静脉周围,由于静脉回流到脑干和小脑,通常会出现侵袭性症状。这种瘘的神经血管内治疗通常具有挑战性,因为经动脉栓塞具有高风险并且经静脉栓塞的适应症有限。在海绵窦和横窦/乙状窦硬脑膜动静脉瘘中,静脉回流到岩静脉是危险的,和治疗策略与岩静脉闭塞是必不可少的。此外,应注意通过上岩窦的静脉入路。
