Abstract:
Objective To investigate the clinical characteristics and mechanism of cavernous sinus dural arteriovenous fistula (CSDAVF). Methods The clinical data of 17 CSDAVF patients, including clinical manifestations, characteristics of cerebrospinal fluid (CSF)and neuroimaging,were analyzed.The interventional catheter embolization of CSDAVF and postoperative follow-up were performed. Results Of the 17 subjects with CSDAVF, 5 (29.4%) were men and 12 (70.6%)were women (sex ratio=1:2.4).The average age of onset was (58.12±14.61)years old. Older CSDAVF patients were prone to be complicated with hypertension than general population at the same age. Onset symptoms included headache in 6 cases,eye symptoms in 5 cases,intracranial murmur in 2 cases,diplopia in 2 cases, dizziness in 1 case and slurred speech in 1 case. Digital subtraction angiography (DSA) was performed in all 17 patients. Further embolization was applied in 14 patients and had satisfactory outcome. In CSDAVF patients with headache, 2 patients showed orthostatic headache as initial symptom. One of them with intracranial hypotension reported exophthalmos 3 months after the onset. Those two patients remained asymptomatic during 3-year and 2-year follow-up after receiving interventional catheter embolization for CSDAVF. Conclusions CSDAVF usually occurs in middle-aged and older women, especially in those with hypertension. CSDAVF varies in clinical manifestations. A special attention should be given to orthostatic headache which can be presented as the initial symptom in few patients with CSDAVF. CTA or DSA should be considered in patients with clinically suspected CSDAVF to rule out the possibility of CSDAVF. The interventional catheter embolization is the primary treatment of CSDAVF.
