Marginal sinus fistulas (MSFs) are uncommon vascular anomalies. Occasionally, the dominant venous drainage is forced retrograde up the inferior petrosal sinus and into the cavernous sinus, causing chemosis, proptosis, and ocular hypertension, mimicking a carotid cavernous fistula. This atypical clinical presentation may lead to misdiagnosis and inappropriate hazardous treatment of an MSF. Identifying the site of the fistula and understanding the anatomy of the venous drainage are critical in providing appropriate, safe, and efficacious endovascular treatment.
边缘窦瘘(MSF)是罕见的血管异常。偶尔,主要的静脉引流会被迫逆行向上经岩下窦进入海绵窦,导致结膜水肿、眼球突出和眼压升高,酷似颈动脉海绵窦瘘。这种不典型的临床表现可能导致MSF的误诊和不适当的危险治疗。确定瘘管的位置并了解静脉引流的解剖结构对于提供适当、安全和有效的血管内治疗至关重要。
