Ruptured dural arteriovenous fistula and sinus venous thrombosis following surgical resection of a vestibular schwannoma: Case report and review of the literature
Dural arteriovenous fistula (DAVF) is a rare vascular malformation. Strong evidence suggests that the development of DAVF in adults is acquired and multifactorial. The link between cerebral venous thrombosis and DAVF is probably explained by dynamic changes in the venous drainage pattern. We report...

Summary: | Dural arteriovenous fistula (DAVF) is a rare vascular malformation. Strong evidence suggests that the development of DAVF in adults is acquired and multifactorial.
The link between cerebral venous thrombosis and DAVF is probably explained by dynamic changes in the venous drainage pattern.
We report the case of a 34-year-old man admitted to the emergency department for seizure and headaches. The patient had a medical history of right vestibular schwannoma resection 9 months earlier, complicated by untreated asymptomatic sigmoid sinus thrombosis.
At admission, CT scan revealed a spontaneous temporal intracerebral hemorrhage associated with ventricular hemorrhage due to the rupture of a DAVF diagnosed by complementary CT angiography.
External ventricular drainage was performed in emergency, followed by endovascular exclusion of the DAVF. Good neurological outcome was achieved, with complete exclusion of the vascular malformation.
This clinical case underlines the absence of guidelines on the use of anticoagulation drugs to treat postoperative venous sinus thrombosis and to potentially prevent DAVF as a late complication following cerebellopontine angle surgery. |
