O-032 Venous Blood Flow Visualization in Sigmoid Sinus Diverticulum Using MRI

ConclusionPT caused by SSD may be caused by a unique flow pattern in the SSD and sinuses as visualized on both MRV and CFD.Abstract O-032 Figure 1Townes projection CFD analysis of a patient with a left SSD and an upstream stenosis in the transverse sinus. The pretreatment analysis (A) shows a jet of flow from the stenosis into the SSD (arrow), vortex of flow in the SSD (double arrow), and a vortex component of flow in the sigmoid sinus down-stream from the SSD (arrow head). The post-treatment model (B) shows absence of the flow in the SSD as well as decreased vortex component of flow in down-stream sigmoid sinusDisclosuresM. Amans: None. E. Kao: None. S. Kefayati: None.
