Resection and replacement of the superior sagittal sinus for treatment of a parasagittal meningioma: technical case report.

We report a case of the complete resection of a parasagittal meningioma, including an 8-cm length of the superior sagittal sinus and adjacent dura. Flow through the sagittal sinus was reestablished through an interposed saphenous vein graft. Intraoperative angiography confirmed immediate patency of the graft, as did delayed angiography performed at 8 days. Follow-up magnetic resonance angiography 9 months after surgery demonstrated continued patency of the graft. Sagittal sinus replacement with a vein graft can be safely performed during Simpson Grade I resection of parasagittal meningiomas.
