@CWong94262 It’s a pretty result. Done as part of a trial or has it become your preferred modality for unruptured mca bif?

[Matt Bender @mtbendermd]

@francisdeng delighted to have found the operative video ;)

Spinal extradural arachnoid cyst surgery. Profound redundant arachnoid, mercifully small dural defect. Mysterious that some pts have orthostatic HA and others compressive myelopathy.

Dilemma addressed by @MarkMamloukMD @Niklas_Luetzen recently PMID 40441881

[Matt Bender @mtbendermd]

@francisdeng @issclsociety Wish I hadn’t forgotten to hit record on the scope… amazing how redundant and billowing the arachnoid was from a relatively small rural opening. Bone thinning (on CT from 5 yrs earlier) attests to chronicity/congenital nature, just tipped over the symptomatic ledge.

[Matt Bender @mtbendermd]

Contemplated this case while traveling to inaugural @issclsociety mtg. Pt in 20s w numb/weak BLE with bend/twist. Never HA.

Spinal extradural arachnoid cyst

Analagous to a Type II CSF leak

Straightforward OR... Resect extradural arachnoid, close small dorsal dural defect

Thank you to all the attendees who joined the inaugural @issclsociety meeting. The world experts on #spinalCSFleak!

@CWong94262 Nice tool, not available here in the US. Not sure I agree about critical stenosis with minimal gradient and normal SSS pressures

Tendency to stent-adjacent stenosis could be another distinction between extrinsic (where it def happens), intrinsic, and CVST-induced IIH

[Matt Bender @mtbendermd]

Curious about experiences stenting IIH post-CVST?

Despite diffuse stenosis and irregular walls, even crossing jugular bulb, I've had great results in pts w recalcitrant papilledema.

Route92 half-cath w Tenzing delivery assist is transformational technology for sinus stenting.

@TareqKass You access the IJ? Curious what benefits you’ve seen to that approach?

[Matt Bender @mtbendermd]

@kasireddy398 Thanks! With CVST, they’re often on anticoagulation at baseline.

I still use DAPT, simple asa325 and plavix75 daily for 3mos. No p2y12 testing, eventually taper down to asa81

[Matt Bender @mtbendermd]

@visishs @BAFOUND @cvsection @SNISinfo I thought terminus/A1 looked most suspicious on DSA, but ACoA bled with minimal manipulation. You’re right I could have inspected/clipped the basilar but there was so little post fossa blood that I was pretty convinced it hadn’t bled

[Matt Bender @mtbendermd]

Which of these aneurysms do you think ruptured? Based on imaging? Based on intra-op findings?

I'm still not certain. I initially deferred the basilar, ultimately took hybrid approach to cure all

[Matt Bender @mtbendermd]

@visishs @PennNSG @cvsection @YoungNIR I can count on one hand the number of times I’ve used multiple arterial access points. Are you using that approach often? Allcock maneuver and a big injection could also capture it

IT cardene works best when started before any sign of ischemia in aneurysmal SAH @URNeurosurgery @URNeuroscience

[W David Freeman, MD, FRSM, FNCS, FAAN @freemanwd]

🚨 New study in Clinical Neurology and Neurosurgery on aneurysmal subarachnoid hemorrhage (aSAH) management 🩸 🧠

Anticipatory initiation of Intrathecal Nicardipine (ITN)—given before clinical or imaging evidence of delayed cerebral ischemia (DCI)—significantly reduces DCI parenchymal infarcts compared to controls (31.3% vs 55.2%).

Key findings:
📉 Starting ITN prior to intra-arterial (IA) spasmolytics significantly lowers the need for serial IA treatments for recalcitrant vasospasm from 71.4% down to 23.1%.

🛡️ It is a safe intervention with no increased risk of EVD-related complications or meningitis.

⚠️ Timing is everything, because reactionary ITN given after DCI onset did not reduce the rate of additional infarcts or the need for serial IA treatments.

Question: Does this article change your practice?
