Ruptured PICA vermian feeder aneurysm causing 4th ventricular hemorrhage. Beyond the foramen of Luschka, with no critical branches or perforators at risk, stat PAO with the aneurysm performed. Nidus embo in a seprated session. Comatose on arrival, the patient recovered to mRS 1.

Unveiling a new intracranial stent design at WFITN2026 Busan. No trade-off of traditional designs, open-cell vs closed cell stent. This is a semi-open-cell stent for ICAD & aneurysms. Expecting first-in-human soon.

A challenging tentorial durla AVF primarily fed by Davidoff Schechter A. & A. of Wollschlaeger. Also, bilateral MMAs, ICAs via MHTs, OAs, STAs, etc. Shunt reductio by taking Davidoff Schechter & Wollschlaeger, then plug & push from Rt MMA feeder achieving complete embo.

A man with debilitating #pulsatiletinnitus causing suicidal ideation. Exam & images indicate large posterior condylar vein & sigmoid sinus dehiscence as etiologies. Sig. sinus resurfacing & embolization performed. After that, his symptoms improved by ~90%. Back to normal life.

Pediatric pial AVFs are a distinct disease, not an AVM. Direct AV shunt without a nidus. Straightfoward curative embo is possible. This case was cured in a single session, 20 min fluoro-time, <1 hr total procedure time. Understanding the pathology changes everything.

Glomus tympanicum: a remarkable atlas of middle ear blood supply. Superior tympanic A. from MMA, inferior tympanic A. from APA, small pharyngotympanic A. from APA, stylomastoid A. from Post. auricular A. But no labyrinthine A. from AICA or no caroticotympanic A. from ICA.

C1 AV fistula — complete occlusion. Often treated surgically due to pial risk, but not all cases require open surgery. Selected anatomy (single feeder, no critical pial branch) → curative endovascular treatment is possible. Key, anatomy. PT's symptoms improving very next day.

Engineering challenge for 0.088 catheter systems: flexibility vs support. Toro addresses this with “Micro-flex Technology,” offering an interesting engineering solution. First-in-US cases went very well. globenewswire.com/news-relea…

Honored to be invited by @DCNSNeuro & Stroke Program at Univ of Calgary. Delivered two Grand Rounds (A Structured Approach to Clinical Innovation / Stentplasty for ICAD). It was a privilege discussing with remarkable faculty & staffs. Thank you for the warm welcome.

A delayed AICA/PICA dissection detected on Day 7 after a negative Day 0 study. In high-grade or non-perimesencephalic SAH, repeat DSA at 5–7 days is mandatory—posterior circulation dissections can declare themselves late and rebleed if missed.

First-ever FD Y-stenting -- not previsouly reported even in vitro -- achieved using an electrospun TUBE stent (NV Medtech). TUBE stent provides 60% surface coverage (vs ~30-35% for current metal FD). Presented in BRAIN 2025 & ABCWIN2026 Val-d'Isere.

Tough M1 occlusion from Trousseau's synd. 3 passes-3 different strategies: anterior-division combined technique → posterior-div combo → aspiration only. With cancer-related clots, I dont repeat the same maneuver. Each pass teaches us clot's behavior. Each pass needs a new plan.

At BRAIN 2025 sharing tips for stentplasty of acute large vessel occlusion with embedded ICAD. Works great in a curved lesion. Long plasty (>5min) helps. The more struts the better. Undersized Comaneci / Tiger work better than oversized one in my hands at least.

Benefits of long duration stentplasty using TG dilator compared to conventional rescue treatment for acute LVO with underlying ICAD are "continuous perfusion" & "ease of use". I will discuss this in my upcoming talk @svinsociety 2025 Orlando.

Intolerable pulsatile #tinnitus due to petrous ICA stenosis inducing turbulence. After angioplasty & stenting (balloon mounted stent), #pulsatiletinnitus is completely gone.
