AMERICAN JOURNAL OF ROENTGENOLOGY. MDCT Venographic Patterns of Dural Venous Sinus Compromise After Acute Skull Fracture

Matthew A. Rischall, Kevin H. Boegel, Christopher S. Palmer, Barbara Knoll and Alexander M. McKinney

OBJECTIVE. Prior studies have shown that skull fractures overlying the dural venous sinuses predispose the patient to an increased risk of dural venous sinus thrombosis (DVST). However, extrinsic compression may also cause sinus compromise and simulate thrombosis. This study set out to evaluate the prevalence and discernibility of DVST versus direct sinus compression in the setting of an overlying skull fracture.
