Large vessel occlusion stroke patients should be taken for thrombectomy within 7 hours, even if imaging doesn’t look favorable…
Honored to present LASTE results @slice_inr together with @CostalatV @CarolineArquiz1 @lapergue6. Strong benefit of thrombectomy within 7 hrs in unlimitedly large core.NNT 4.Equal benefit in ASPECTS 0-2 vs 3-5 & lower mortality.
No more reasons to exclude pts based on imaging !!
They are limited and are only used to assist in decision making but important to be familiar with them.

13% of patients will die in the hospital of aneurysmal subarachnoid hemorrhage, and up to 26% will die before arriving at the hospital.
If ≥2 first-degree relatives with cerebral aneurysms -> you have a 12% chance of having one

So many letters, so many ❓❓❓
& so the discussion ensues - which imaging are YOU going to use for intracranial aneurysm dx + mgt?
Luckily, Beaman et. al go thru +/- of imaging modalities - both old + new🧠
Let's begin! 👇
Interesting results comparing medical management to med + thrombectomy for isolated PCA strokes.
Notes:
-Multicenter observational
-Higher symptomatic ICH and END in thrombectomy patients
-mRS not better for thrombectomy patients
RCT may be warranted

Important arterial connections at the skull base. Be careful with embolizations of the middle meningeal artery that may cause facial paralysis or hearing loss.

It appears that clots should be removed even when the core infarct is large, 2 new studies in NEJM:
#thrombectomy for all

Sturge-Weber Syndrome patients may present to the hospital with stroke like episodes that often fully resolve over a period of days, weeks, or months.
MRI rarely shows diffusion restriction, but impaired venous drainage is common on perfusion imaging.

Thrombectomy beyond 24 hours from last known well? This study demonstrated worse outcomes overall (as one might expect), but similar hemorrhages/complications compared to the 6–24 hours group. Study by @ashabanmd et al.

New CASSISS study from China compares medical management to medicine + Wingspan stenting in patients with ICAD.
->No significant difference
->Relatively low stroke rates in both groups (see SAMMPRIS)
->Question remains:why do some patients still fail?
