inferior sagittal sinus thrombosis

This relatively small sinus collects anterior pericallosal veins. Drained blood enters the major dural sinuses: Superior sagittal sinus (SSS), inferior sagittal sinus (ISS), lateral sinus (LS), cavernous sinus and straight sinus, and then to the internal jugular vein (IJV) Superficial venous system has numerous anastomses and predominantly drain the … Cerebral venous thrombosis is located in descending order in the following venous structures: Major dural sinuses: Superior sagittal sinus, transverse, straight and sigmoid sinuses.

These layers fit snugly into each other in almost all locations except for certain avenues, where they split to accommodate the venous channels. Conversely, 2D-TOF imaging in the sagittal plane alone, which would be expected to improve the signal and enhance visualization of these posterior regions, would be suboptimal for showing the superior sagittal sinus, straight sinus, inferior sagittal sinus, portions of … These risk factors should be investigated in patients with cerebral venous thrombosis.
