SAH case with no aneurysm. The key? Not a positive finding - a negative one. After proper angling & longer injection, proximal PICA showed up. Distal portion occluded from dissection. Treated with PAO. Patient did well with partial Wallenberg. Always look for what's not there.

Rare Case: Cognard Type V dAVF causing progressive myelopathy. Posterior fossa dAVF draining into spinal veins. Cured with transvenous embolization by drilling through occluded jugular bulb. Don’t forget cranial dAVFs in unexplained cord syndromes.

Our in-vitro study confirms what many operators intuitively feel in the angio suite: Stiffer microguidewires significantly improve catheter deliverability through tortuous anatomy. Less wire kickback & lower pushing force.

Challenging cavernous dural fistula: no IPS access, tortuous SOV/facial veins. Drilled occluded IPS w/ 0.014 wire + microcath. First entering normal cav sinus., another attempt to arterialized sinus! Complete embo cure w coil/onyx. Fluoro time <40 min. Patient back to normal!

Facial venous malformation, R side kept enlarging. An accidental MRA revealed an AVM in the R masseter shunting into the VM, raising venous pressure. Treatment strategy: .→ first AVM embolized completely. → Then direct sclerotherapy Lesson: .Hidden AVMs can drive VM growth.

Did a transradial cerebral angio without knowing the patient had an aberrant right subclavian artery. Turned out to be a bovine arch and direct aortic origin of the left vertebral. Basically, a vascular version of a haunted house. Would not recommend!

Encountered an aberrant right subclavian artery today—but instead of the usual retroesophageal course, this one passed anterior to both the trachea and esophagus. An extremely rare variant—seen in less than 5% of ARSA cases!

We tracked how brain arteries change over time. ✅ Arteries lengthen & become tortuous over decades.✅ Factors such as hypertension & diabetes accelerate change.✅ Insights could refine stroke & aneurysm risk prediction. Research lead by Dr. Chien.

Enterprise stent showed less thrombus formation than other non-coated stents—yet the manufacturer doesn’t claim this as a feature. An overlooked benefit or intentional silence on anti-corrosive parylene coating on Enterprise? .#mdpibioengineering

We published TG dilator stent-plasty FIM cases in JNIS last year. What happened to patients who underwent conventional angioplasty w/wo stenting instead of TG dilator stent-plasty? Here is the summary.
