Papilledema revisiting after sinus angioplasty of chronic cerebral venous sinus thrombosis.

This case series aimed to review the significance of revisiting papilledema after successful cerebral venous sinus thrombosis (CVST) management with sinus angioplasty. Four patients presented with blurring and transient obscuration of vision with papilledema, headache, tinnitus, and vomiting. On magnetic resonance venography and digital subtraction angiography, chronic transverse sinus thrombosis was diagnosed for which patients underwent endovascular intervention (stenting). After the resolution of CVST, patients developed the recurrence of symptoms which on digital subtraction angiography revealed dural arteriovenous malformation (DAVM). DAVM and papilledema resolved with endovascular embolization. This case series highlights a need of constant monitoring of CVST cases after the endovascular intervention.
