Abstract

Introduction Venous sinus stenting (VSS) is a safe, effective, and increasingly popular treatment option for selected patients with idiopathic intracranial hypertension (IIH). Serious complications associated with VSS are rarely reported.

Methods Serious complications after VSS were identified retrospectively from multicenter databases. The cases are presented and management strategies are discussed.

Cases Six major acute and chronic complications after VSS were selected from a total of 811 VSS procedures and 1466 venograms for IIH. These included an acute subdural hematoma from venous extravasation, cases of both intraprocedural and delayed stent thrombosis, an ultimately fatal cerebellar hemorrhage resulting in acute obstructive hydrocephalus, venous microcatheter perforation during venography and manometry, and a patient who developed SAH and SDH after cerebellar cortical vein perforation. The 6 cases are reviewed and learning points regarding complication avoidance and management are presented.

Conclusion We report on 6 rare, major complications after VSS for IIH. Familiarity with these potential complications and appropriate timely management may allow for good clinical outcomes.
