目的探讨海绵窦区硬脑膜动静脉瘘(CSDAVFs)的临床表现、诊断、鉴别诊断和治疗方法,提高对此疾病的认识。方法报道2例CSDAVFs患者,结合文献复习进行分析。结果 2例患者均以眼痛伴眼肌麻痹为核心表现,经全脑血管造影确诊为CSDAVFs,经岩下窦行静脉栓塞后明显改善。结论因CSDAVFs病情复杂,早期诊断困难,应尽早行全脑血管造影明确诊断,经岩下窦行静脉栓塞治疗安全、有效。 Objective To investigate the clinical manifestations, diagnosis, differential diagnosis and treatment of cavernous sinus dural arteriovenous fistula (CSDAVFs) and to raise awareness of the disease. Methods Two cases of CSDAVFs were reported and analyzed with literature review. Results All the 2 patients were characterized by ocular pain accompanied with ophthalmoplegia. CSDAVFs were confirmed by whole cerebral angiography and were significantly improved by embolization of inferior petrosal sinus. Conclusion Because CSDAVFs are complicated and difficult to diagnose early, CSDAVFs should be diagnosed as early as possible by whole cerebral angiography, and safely and effectively treated by inferior petrosal sinus vein embolization.
