Cerebral angiography (Figure 1b) 2 days after admission revealed a partially occlusive thrombus within the middle third of the superior sagittal sinus
Clinical and radiological findings were more in favour of PRES rather than superior sagittal sinus
thrombosis and subsequent MRI confirmed resolution of the pathology.
which include meningitis, epidural abscess, subdural abscess, intracerebral abscess, Pott's puffy tumor (frontal bone osteomyelitis), superior sagittal sinus
thrombosis, and cavernous sinus thrombosis.
Pretreatment angiographic images revealed dilatation of bilateral middle meningeal artery branches and transosseous superficial temporal artery branches supplying an AVF of the superior sagittal sinus
The bone was removed for about 12x12 cm, which adhered to the dura mater near the sagittal sinus
The MRI scan identified thrombosis of the anterior superior sagittal sinus
with bifrontal infarctions.
Unlike ineffective fetal heart rate sensors, Noninvasix's probe uses direct, real-time monitoring of cerebral venous oxygenation in the fetus' superior sagittal sinus
to determine the baby's welfare.
After recurrence of her headache and continued decline in her vision, an angiogram was obtained at an outside hospital that revealed a massive DAVF fed by meningohypophyseal and middle meningeal vessels, with fistulous involvement of the sagittal sinus
, straight sinus, and both transverse sinuses (Figure 1).
Craniotomy is generally performed around the vertex, allowing for access to all portions of the superior sagittal sinus
, though careful intraprocedural positioning is required to adequately position the head above the heart to promote venous drainage while minimizing the risk for air emboli formation (Ekseth et al.
Unlike traditional fetal welfare monitoring systems, which use changes in basal heart rate to indirectly assess fetal asphyxia, Noninvasix's novel solution utilizes optoacoustic monitoring of cerebral venous oxygenation in the superior sagittal sinus
to directly measure the amount of oxygen available to the baby's brain.
