Deans' stroke musings: Non-ischemic cerebral enhancing lesions secondary to endovascular aneurysm therapy: nickel allergy or foreign body reaction? Case series and review of the literature

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

INTRODUCTION Delayed onset of non-ischemic cerebral enhancing (NICE) lesions is a rare complication of intracranial aneurysms' endovascular therapy (EVT). The purpose of this study is to report this rare complication and its potential pathophysiology in a single-center case series and review the relevant literature.
METHODS After retrospective review of all patients managed by EVT at our institution from January 1, 2012 to December 31, 2014, 2 out of 374 patients (0.5 %) with such a complication were identified. Skin patch testing was performed with all endovascular devices used in the two patients and with the European baseline series, including nickel. All previously published cases in the English literature were reviewed based on exhaustive PubMed and Embase research.
RESULTS Patient no. 1 developed NICE lesions 1 month after balloon-assisted coiling of a ruptured anterior communicating artery aneurysm. Patient no. 2 developed NICE lesions 12 months (the longest delay reported to date for such a complication) after the treatment of a right carotid-ophthalmic aneurysm by loose coiling and flow diversion. Patient no. 2 demonstrated nickel skin reactivity, but none of the two patients presented allergic reaction to the devices used during interventions.
CONCLUSIONS Based on our observations and review of the literature, we hypothesize that delayed non-ischemic cerebral enhancing lesions after EVT are more likely related to foreign body emboli rather than nickel allergy. The two presented cases demonstrate the potential for recurrence and prolonged fluctuation of NICE lesions, warranting long-term follow-up for all patients presenting this complication.
