Abstract
Prior to the antibiotic (AB) era, cavernous sinus thrombosis (CST) was almost uniformly fatal. AB therapy has significantly reduced mortality, but additional treatment with anticoagulants (AC) has remained controversial. We reviewed our experience with seven cases, as well as the literature since Lyons9 1941 introduction of AC treatment, to determine effectiveness, complications, and morbidity among survivors. We divided the cases into (1) those treated with AB alone, and (2) those treated with a combination of AB and AC. We found no conclusive evidence for reduction of mortality when AC was used in combination with AB. However, early AC therapy reduced morbidity (blindness, stroke, ophthalmoplegia, hypopituitarism, focal seizures, and vascular steal syndrome), whereas delayed or inadequate use provided no apparent benefit above AB therapy alone. Complications of AC therapy were rare; cerebral venous thrombosis occurred frequently, but in association with dural sinus thrombosis as a direct result of the disease. We conclude that AC therapy is indicated early in the treatment of CST to reduce morbidity among survivors.
