    Abstract:
    BACKGROUND: Preoperative venogram of the superior sagittal sinus (SSS) is helpful to plan the surgical resection strategy in patients with parasagittal meningiomas invading the SSS. METHODS: Catheter 3-dimensional rotational venography (3D-RV) allows for SSS patency assessment and detection of alternative venous cortical drainage routes in patients with contraindication for magnet resonance venography. It is unknown if separate bilateral internal carotid artery 3D-RV followed by postprocessing 3D-3D fusion (technique 1) achieves the same imaging results as simultaneous bilateral internal carotid artery 3D-RV without postprocessing fusion (technique 2) needed. RESULTS: In this report we were able to confirm in 2 patients that both techniques achieve comparable imaging quality with similar amount of contrast use. CONCLUSIONS: Although technique 2 requires less radiation, technique 1 is favored due to the need for only 1 vessel access site and catheter with reduced risk for access site and ischemic complications.
