Deans' stroke musings: A New Therapeutic Strategy for Acute Ischemic Stroke

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.

A New Therapeutic Strategy for Acute Ischemic Stroke

Finally someone looking at something other than tPA for hyperacute therapy.

Background and Purpose—Intravenous tissue-type plasminogen activator (IV tPA) frequently fails to recanalize proximal middle cerebral artery (MCA-M1) obstructions, preventing favorable outcomes. Only neurointerventional procedures prevail in these cases, but well-equipped centers remain scarce. A new therapeutic strategy consisting of a second IV thrombolysis with low-dose tenecteplase was applied.

Methods—Consecutive patients with an MCA-M1 occlusion that did not reopen at the end of IV tPA perfusion received IV tenecteplase (0.1 mg/kg). Partial or complete thrombolysis in myocardial infarction recanalization (Thrombolysis In Myocardial Infarction grade 2/3) and intracerebral hemorrhage were assessed by magnetic resonance imaging ≈24 hours later. Clinical outcomes at 3 months were evaluated with the modified Rankin score.

Results—Among 40 patients with MCA-M1 occlusions who received IV tPA, 13 were treated according to the protocol of sequential combined IV thrombolytics. Baseline National Institutes of Health Stroke Scale score was 15. At a mean of 16.8 hours after IV thrombolysis, the recanalization rate was 100% (2 with Thrombolysis In Myocardial Infarction grade 2, 11 with Thrombolysis In Myocardial Infarction grade 3). Intracerebral hemorrhage occurred in 4 of 13 (31%) patients, with no symptomatic hemorrhage. Good clinical outcomes (modified Rankin score=0/1) were achieved in 9 of 13 (69%) patients. Functional outcomes were very similar to those of 13 patients with early IV-tPA recanalization. Among 4 patients treated as protocol violations, 1 presented with a lack of recanalization and a parenchymal hematoma type 2.

Conclusions—For patients with MCA-M1 occlusions treated with IV tPA but without early recanalization, a second bolus of IV tenecteplase (0.1 mg/kg) may be a relatively safe, effective, and easy option in carefully selected cases, but additional studies are needed to confirm these findings.
