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.

Influence of microcatheter position on first-pass success of thrombectomy for acute ischemic stroke

Your definition of successful recanalization is totally wrong!  Success is not opening the artery, IT IS 100% RECOVERY. When the hell will you GET THERE? We won't have correct objectives on stroke research until we get survivors in charge.

Influence of microcatheter position on first-pass success of thrombectomy for acute ischemic stroke

Abstract

Objective

In acute ischemic stroke, patient outcomes can be improved by first-pass successful recanalization of the occluded vessel. This study investigated whether microcatheter position could influence the success of first-pass recanalization.

Methods

We retrospectively analyzed 59 consecutive acute ischemic stroke patients who underwent intra-arterial thrombectomy with stent retrievers for middle cerebral artery (M1) occlusion. Angiography findings obtained via the first pass of the microcatheter were analyzed. The microcatheter was considered to be inserted into M2 segments that gave rise to parietal arteries (M2P) if the anterior or posterior parietal artery was observed. Recanalization results were compared between patients with and without microcatheter insertion into M2P. The angle and diameter of vessels were measured using post-procedural magnetic resonance angiography (MRA).

Results

The rate of first-pass successful recanalization (modified thrombolysis in cerebral infarction score of ≥2b) was significantly higher in patients with microcatheter insertion into M2P than in those without (56% vs 22%, p = 0.016). The number of passes was lower in patients with first-pass microcatheter insertion into M2P than in those without (1.8±1.0 vs 2.5±1.5, p = 0.05). The mean diameter of M2P was significantly larger than that of the other M2 (1.9±0.6 mm vs 1.7±0.5 mm, p = 0.035). The M1/M2P angle was significantly smaller than that between M1 and the other M2. (49±32° vs 67±31°, p = 0.006).

Conclusions

First-pass microcatheter insertion into M2P may contribute to fast successful recanalization in patients with M1 occlusion who undergo intra-arterial thrombectomy using stent retrievers.
