Contrast enhancement of chronic subdural hematomas after embolization of the middle meningeal artery.
Chronic subdural hematomas are a common neurosurgical presentation. They are difficult to treat, and current interventions - namely surgical evacuation - are not without complications or recurrences. ⋯ We have noted an interesting phenomenon in our patients following endovascular embolization, which is that the subdural hematoma is stained with contrast following the procedure. This ties into the basic physiology of chronic subdurals, which parasitize the middle meningeal artery during the process of membrane formation and neovascularization, which has previously been reported.

The aim of this retrospective study is to evaluate medium-term results of undersized balloon angioplasty and stenting for symptomatic high-grade (70-99%) stenosis of a major intracranial artery with Enterprise stent. ⋯ In this retrospective single-center study undersized balloon angioplasty and deployment of a self-expandable stent with relatively low radial force was safe and effective for endovascular treatment of high-grade intracranial arterial stenosis with high technical success rate, low periprocedural complication rates and favorable medium-term follow-up results.
