However, in some cases there is incomplete obliteration or even no obliteration at all. This can cause cases a non-communicating cyst or even a communica...

The operative treatment of 37 patients with unicameral bone cysts was compared with the newer method of steroid injection in 20 patients whose cysts were similarly predisposed with respect to mode of presentation, location, age, and sex. In the surgical group the average operative time was 100 min, with a mean estimated blood loss of 300 ml. The recurrence rate was 40%, rising to 88% in patient...

BACKGROUND AND PURPOSE Flow-diverting stents are increasingly being used for the treatment of complex intracranial aneurysms, but the indications for their use in lieu of traditional endovascular PVO have yet to be precisely defined. The purpose of this study was to review the clinical and imaging outcomes of patients with intracranial aneurysms treated by PVO. MATERIALS AND METHODS A total o...
