Cranial venous sinus dominance: what to expect? Analysis of 100 cerebral angiographies

Dominância dos seios venosos cranianos: o que esperar? Análise de 100 angiografias cerebrais

ABSTRACT

We report an analysis of the cranial venous sinuses circulation, emphasizing morphological and angiographic characteristics.

Methods

Data of 100 cerebral angiographies were retrospectively analyzed (p = 0.05).

Results

Mean age was 56.3 years, 62% female and 38% male. Measurements and dominance are shown in the Tables. There was no association between age or gender and dominance. Right parasagittal division of the superior sagittal sinus was associated with right dominance of the transverse sinus, sigmoid sinus and internal jugular vein; and left parasagittal division of the superior sagittal sinus was associated with left dominance of the transverse sinus, sigmoid sinus and internal jugular vein.

Conclusion

A dominance pattern of cranial venous sinuses was found. Age and gender did not influence this pattern. Angiographic findings, such as division of the superior sagittal sinus, were associated with a pattern of cranial venous dominance. We hope this article can add information and assist in preoperative venous analysis for neurosurgeons and neuroradiologists.
