Background: Idiopathic intracranial hypertension (IIH) remains a poorly understood and therapeutically challenging disease. Enthusiasm has emerged for endovascular therapy with stent reconstruction of dural sinus narrowing (DSN); however, a complete understanding of the hydrodynamic dysequilibrium is lacking.
Objective: To review and characterize catheter manometry findings including pulsatility changes within the venous sinuses in IIH.
Methods: Cases of venous sinus stent implantation for IIH were retrospectively reviewed.
Background: Stenting for symptomatic intracranial atherosclerotic disease is a therapeutic option in patients in whom medical therapy fails.
Objective: To determine the periprocedural complication rates and mid-term restenosis rates in patients treated with balloon-expandable stents (BESs) compared with self-expanding stents (SESs).
Methods: A retrospective review of consecutive patients treated with intracranial stents at 5 institutions was performed. Predictors of 30-day stroke and death as well as mid-term restenosis rates were analyzed.
Background: Cerebral vasospasm is a major cause of morbidity and mortality following aneurysmal SAH. Nicardipine has previously been used to treat vasospasm utilizing superselective intracranial microcatheter injections.
Objective: To evaluate a simple method of treatment of vasospasm, with slow infusion of nicardipine from a cervical catheter.
Methods: Twenty-seven patients with symptomatic vasospasm were treated over fouryears with cervical catheter infusions. Nicardipine was infused at 20 mg/hour for 30-60 minutes. Angioplasty was used in severe cases at the operator’s discretion. Outcome at discharge and follow-up was evaluated using Glasgow Outcome Score.

OBJECTIVE: To identify procedure-related factors that may affect patient safety and technical outcome.
METHODS: In this prospective study of 57 consecutive patients, the primary end points were intra-procedural technical problems, peri-procedure morbidity and complications. Major peri-procedure complication was defined as all stroke or death at 30 days. Technical failure was defined as inability to complete the procedure due to technical or safety problems. Procedure failure was defined as a procedure outcome of technical failure or major peri-procedure complication. Secondary end points were procedure-related factors that may affect patient safety and technical outcome.
Ahead of Print: Comparison Between Angioplasty using Compliant and Non-Compliant Balloons for Treatment of Cerebral Vasospasm Associated with Subarachnoid Hemorrhage
BACKGROUND: Considerable controversy exists regarding the choice of balloon used for performing angioplasty as treatment of cerebral vasospasm associated with subarachnoid hemorrhage (SAH).
OBJECTIVE: To determine the impact of compliant and non-compliant balloons on angiographic and clinical outcomes among patients with SAH related cerebral vasospasm.
METHODS: Consecutive patients with cerebral vasospasm who underwent balloon angioplasty were included. Patient characteristics, rate of angiographic recurrence, and occurrence of cerebral infarcts in the affected vessel distribution were compared between arteries treated using different balloons.
