Deans' stroke musings: Systematic Review and Meta‐Analysis of Endovascular Therapy Effectiveness for Unruptured Saccular Intracranial Aneurysms

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.

Abstract

BACKGROUND

Currently, endovascular treatment of intracranial aneurysms is limited by low complete occlusion rates. The advent of novel endovascular technology has expanded the applicability of endovascular therapies; however, the superiority of novel embolic devices over the traditional Guglielmi detachable coils is still debated. We performed a systematic review of literature that reported the Raymond–Roy occlusion classification (RROC) rates of modern endovascular devices to determine their immediate and follow‐up occlusion effectivenesses for the treatment of unruptured saccular intracranial aneurysms.

METHODS

A search was conducted using electronic databases (PUBMED, Cochrane, ClinicalTrials.gov, and Web of Science). We retrieved studies published between 2000 and 2022, reporting immediate and follow‐up RROC rates of subjects treated with different endovascular intracranial aneurysm therapies. We extracted demographic information of the treated patients and their reported angiographic RROC rates.

RESULTS

A total of 80 studies from 15 countries were included for data extraction. The RROC rates determined from angiogram were obtained for 21 331 patients (72.5% women, pooled mean age: 58.2 [95% CI]: 56.8–59.6), harboring 22 791 aneurysms. The most frequent aneurysm locations were the internal carotid artery (46.4%, 95% CI: 41.9%–50.9%), the anterior communicating artery (26.4%, 95% CI: 22.5%–30.8%), the middle cerebral artery (24.5%, 95% CI: 19.2%–30.8%), and the basilar tip (14.4%, 95% CI: 11.3%–18.3%). The complete occlusion probability (RROC‐I) was analyzed for Guglielmi detachable coils, the Woven EndoBridge, and flow diverters. The RROC‐I rate was the highest in balloon‐assisted coiling (73.9%, 95% CI: 65.0%–81.2%) and the lowest in the Woven EndoBridge (27.8%, 95% CI: 13.2%–49.2%). The follow‐up RROC‐I probability was homogenous in all analyzed devices.

CONCLUSION

We observed that the coil‐based endovascular therapy provides acceptable rates of complete occlusion, and these rates are improved in balloon‐assisted coils. Out of the analyzed devices, the Woven EndoBridge exhibited the shortest time to achieve >90% probability of follow‐up complete occlusion (∼18 months). Overall, the Guglielmi detachable coils remain the gold standard for endovascular treatment of unruptured saccular aneurysms.
