A & B) Venography via microcatheter run from superior sagittal sinus.
C & D) Single shot of microcatheter. Sample of areas of interest are imaged with mean pressure labeled. Superior Sagittal sinus pressure of 29 mmHg & Sigmoid sinus pressure of 18 mmHg giving a gradient of 11 mmHg. Notice the sheath and guide catheter in the jugular bulb.
E) Single shot with guide catheter taken across area of stenosis with stiff microwire in superior sagittal sinus in AP view
F & G) Single shot of Stent in AP and lateral projection
H & I) Venography again performed from superior sagittal sinus microcatheter run post stenting
J & K) Single shot of microcatheter post treatment. Sample of areas of interest are imaged with mean pressure labeled post stenting. Superior Sagittal sinus pressure of 22 mmHg & Sigmoid sinus pressure of 18 mmHg giving a gradient of 4 mmHg.
