Pongpech S Objective: To describe the ocular findings, endovascular treatment, and clinical outcome in patients with
dural carotid cavernous sinus fistula (CCF).
Material and Method: A retrospective evaluation of 80 consecutive patients who underwent examination and
treatment for dural CCF between January 1997 and December 2004 was performed.
Results: Fifty females and 30 males, with an average age of 49 years (from 6 -80 years) participated in this
study. All patients had more than one clinical signs and symptoms including proptosis (84%), arterialization
of conjunctival vein (93%), chemosis (42%), cranial nerve palsy (52%), elevated intraocular pressure (51%),
and optic neuropathy (13%). Diminished vision was found in 43% of the patients. The degree of visual deficit
ranged from 20/40 to no light perception. After angiographic evaluation, patients were classified to CCF
Barrow’s type B 14%, type C 15%, and type D 71%. Endovascular treatment by transvenous and/or transarterial
embolization was performed in 60 patients (75%). Carotid-angular compression therapy was solely performed
in 19 patients (24%) and was used as an adjunct to endovascular treatment in 30 patients (38%).The follow-up
period ranged from 6 to 94 months. Clinical cure was achieved in 41 patients (51%) and improvement in 30
patients (38%). Anatomical cure was demonstrated by angiogram in 50 patients (63%). Intra-operative
complications were found in three patients including ophthalmic artery occlusion and cerebral infarction.
Eight patients experienced transient aggravation of symptoms including increased proptosis, elevation of
intraocular pressure, choroidal detachment that required suprachoroidal drainage, and venous stasis retinopathy.
Ophthalmic vein thrombosis resulting in central retinal vein occlusion was developed in three patients
and finally caused severe visual deficit. There was no operative mortality.
Conclusion: Selective management with endovascular therapy and manual compression are the effective
treatment for dural CCF. However, sight-threatening complications can develop after therapy due to progressive
ophthalmic vein thrombosis and should be carefully monitored.
