Deans' stroke musings: Is Thrombectomy Worth It for Isolated Posterior Cerebral Artery Occlusion? Meta‐Analysis and Trial Sequential Analysis

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.

Is Thrombectomy Worth It for Isolated Posterior Cerebral Artery Occlusion? Meta‐Analysis and Trial Sequential Analysis

Did you ask survivors whether they were willing to take the risk vs. benefit?

Abstract

BACKGROUND

Thrombectomy is well‐established management for acute ischemic stroke involving large vessel occlusion. However. the potential efficacy of thrombectomy for isolated posterior cerebral artery occlusion remains limited. The study aims to evaluate the benefits of thrombectomy for isolated posterior cerebral artery occlusion.

METHODS

We searched PubMed, Cochrane, and Embase for articles published until September 2023. The primary outcome was good functional outcome at 3 months. The secondary outcomes included excellent functional outcome at 3 months and early neurological improvement. The safety outcomes were symptomatic intracerebral hemorrhage, and mortality at 3 months.

RESULTS

Seven retrospective studies involving 2560 patients with isolated posterior cerebral artery occlusion were included (876 patients receiving thrombectomy). The odds ratio (OR) of good functional outcome at 3 months was 0.93 (95% CI, 0.68–1.28) between 2 groups. The OR of excellent functional outcome (OR 1.23; 95% CI 0.92–1.64) and early neurological improvement (OR 1.82; 95% CI 0.97–3.40) were not different between the 2 groups. Compared with patients with best medical management, those with thrombectomy demonstrated a significantly increased risk of mortality (OR 1.81; 95% CI 1.24–2.65), whereas the risk of symptomatic intracerebral hemorrhage (OR 2.033; 95% CI 0.996–4.148) did not show an increase. Additionally, the results of trial sequential analysis indicated all outcomes were inconclusive.

CONCLUSION

Thrombectomy stands as an available procedure for patients with isolated posterior cerebral artery occlusion; however, it shows no notable benefits in reducing symptomatic intracerebral hemorrhage risk or enhancing function and may raise mortality compared with standard medical management. Further randomized controlled trials are necessary to yield more conclusive evidence.
