DURAL FISTULAS OF THE CAROTID-CAVERNOUS SINUS TREATED BY THE TRANSVENOUS ROUTE - 4 CASES

The authors report 4 cases of symptomatic dural fistula of the carotid cavernous sinus treated by transvenous coils. The objectives of dural fistula treatment are now clearly established and several methods are available. Abstention is the rule for asymptomatic forms, whereas sym ptomatic forms with ophthalmological complications may respond to manu al compression of the jugular vein and the carotid artery, arterial em bolization, radiotherapy or venous embolization.Arterial embolization results in complete cure in 72 % to 78 % of the cases, but it is limit ed by the meningeal supply of the internal carotid artery, with the mi crocatheter the transvenous route makes it possible to treat the menin geal supply from the internal and external carotids without affecting the arterial system, but this technique is restricted by the anatomy o f each patient.
