Dural sinus thrombosis is a relatively rare, but potentially devastating disease. The problem occurs when there is extensive thrombosis of the intracranial dural sinuses, the outflow channels of venous blood from the brain. If recanalization does not occur, venous hypertension can lead to cerebral edema, infarction, and hemorrhage. Treatment of this disease usually involves anticoagulants, but with mixed results. Endovascular approaches using direct infusion of thrombolytic drugs into the occluded sinuses may result in excellent recanalization and improved patient outcomes.

Temporal bone venous prolapse with or without meningeal prolapse are a frequent problem in middle ear and labyrinth surgery. 178 translabyrinthine approaches with prolapse study are reported in this retrospective study. Superficially, the approach was narrow in 43% of the patients because of a lateral sinus prolapse in 27 cases or a temporal meningeal prolapse in 50 patients. Surgery was technically difficult in 8 patients with lateral sinus prolapse associated with meningeal prolapse. Deep labyrinth structure reaming was difficult in 40% because of an abnormal position of the jugular bulb and/or the superior petrosal sinus. Both superficial and deep approach was narrow in 22% of the cases. 23 lateral sinus prolapses associated with transhigh jugular bulb and 17 lateral sinus prolapses associated with superior petrosal sinus prolapses were noted and reported. Expectation of these anatomical variations, more frequent on the right side, should be established before surgery with imaging studies in order to perform a safe and efficient surgical procedure.
