Introduction/Purpose Venous diverticula are rare neurovascular defects that consist of an outpouching in the wall of a venous sinus. Multiple cases of venous diverticula have been found in the sigmoid sinus and jugular bulb, with the presence of dehiscence at the base of the temporal bone. Debilitating symptoms can be associated with the presence of venous sinus diverticula warranting open or endovascular treatment. This project seeks to report trends in patient presentation, successful treatment modalities for diverticula cure, and accompanying patient outcomes associated with venous sinus diverticula.

Materials and Methods 9 patient cases with diagnosed transverse sigmoid or jugular bulb diverticula were reviewed. Qualitative analysis was preformed to determine the prevalence of dehiscence, laterality of diverticula, predominant symptoms at presentation, and treatment modalities. Patient outcomes and responses to treatment were compared and associated morbidity identified.

Results 66.6% (6/9) of patients presented with a right sided venous diverticulum, the majority (4/6) being in the transverse sigmoid sinus. 22.2% of patients (2/9) presented with left jugular bulb diverticula and 11.1% (1/9) presenting with a left transverse sigmoid diverticulum. The was a female preponderance with 55.6% (5/9) of the affected patients being women. All patients received a stent- assisted coil embolization for diverticula resolution. 77.8% (7/9) patients had improvement or complete symptom alleviation following endovascular coiling. Zero patients had post operative complications.

Conclusion We bring forth nine novel cases of venous diverticula, to contribute to the existing cases of venous sinus diverticulum. Trends in the incidence and epidemiology of our venous diverticula cases closely adhere to those outlined in the literature. Additionally, we find endovascular treatment for venous sinus diverticula obliteration have favorable outcomes in regard to symptom alleviation with minimal complications associated with treatment.
