Hello everyone, my name is Alhamza Albiadi, an Associate Professor of Neurology and Neurosurgery at the University of Pittsburgh School of Medicine.

I'm a Stroke Specialist and Neurointerventionist,

serve as the Director of Pediatric Neuroendrovascular Surgery and Surgical Co-Director of the Neurovascular Center of Excellence at Children's Hospital UPMC.

Today I'll be highlighting key concepts in pediatric cerebrovascular disease, current strategies, and where the field is heading.

This is an educational discussion and reflects my clinical judgment and experience.

So, the key principle is simple but critical.

Pediatric cerebrovascular disease is not adult in smaller bodies.

The causes are fundamentally different as children are dominated by arteriopathies like moya moya cardiac

and embolic sources genetic syndromes

and vascular malformations hemorrhagic strokes makes up almost half of pediatric

cases compared to only 10 to 15 in the adults

and their symptoms are subtle often non-focal

or seizure-like leading to diagnostic delays everything we do must focus not just on acute survival but on long-term neurodevelopmental trajectory.

In the acute ischemic setting, the biggest challenge we face is the recognition and time to diagnosis.

Dedicated pediatric stroke alerts and multidisciplinary mobilization dramatically improve the accuracy and workflow.

MRI with DWI and MRA remains our definitive tool to diagnosis of ischemia and assessing vessel status.

IV thrombolysis remains off-label, used selectively in adolescents who meet adult criteria at expert centers.

Endovascular thrombectomy is increasingly used for large vessel occlusion, with a growing evidence-based, showing feasibility and safety,

even though the data are largely extrapolated from adults.

Prevention must be tailored to etiology.

For instance, non-Moyomoy arteriopathy typically responds well to antiplatelet therapy.

Moyomoy disease, however, is unique.

Surgical revascularization with indirect bypass, EDAS, remains the most effective long-term neovascularization strategy.

For sickle cell disease, chronic transfusions are still the standard guided by TCD velocities.

And in children with cardiac disease or thrombophilias, long-term anticoagulation is often necessary.

Remember, each child requires individualized planning and multidisciplinary input.

Pediatric AVMs behave differently.

They are dynamic, can recruit new feeders, and can carry high lifetime risk of hemorrhage.

After rupture, the first phase is damage control, stabilizing the child, managing ICP, and addressing the hematoma.

Definitive AVM treatment is usually delayed until it's safe.

Our curative tools include microsurgery, which remains the gold standard for accessible lesions,

stereotactic radiosurgery for deep inaccessible AVMs, and targeted endovascular embolization as an adjunct.

When performing pre-operative embolization, precision is everything.

The key goal is to reduce the nitis size without compromising the venous drainage or normal perforators.

Vanum-gallon malformation is the benchmark of our neuroendovascular subspecialty.

These babies present critically with neonatal heart failure and pulmonary hypertension.

Older infants, however, may present with microcephaly or hydrocephalus.

Our treatment strategy is stage endovascular embolization, a controlled and gradual shunt reduction.

The goal is to relieve the life-threatening venous hypertension and allowing the cardiovascular system to recover.

Success relies on ultra-fine microcaptors, precise liquid embolics, and focal coiling of arteriovenous chuntings for controlled obliterations.

Our pediatric neuroendrovascular field also focuses on targeted therapeutics and functional testing.

Intraarterial chemotherapy for retinoblastoma, usually delivered through the ophthalmic artery, with remarkable vision-saving outcomes.

And for functional localization, the wider test still plays an important role in complex epilepsy or tumor cases,

helping map the language and memory dominance to avoid postoperative deficits.

Effective pediatric cerebrovascular care depends on a robust team.

Neurointervention, neurosurgery, pediatric vascular neurology, and pediatric critical care are the core of this team.

Supporting roles from cardiology, hematology,

genetics, rehab, and social work are essential in guiding etiology and long-term recovery.

These children needs both ongoing imaging surveillance and lifelong functional monitoring.

The future of pediatric neurovascular disease is precision-based.

Genomics, enhanced by endoluminal and liquid biopsy techniques,

are beginning to identify actionable mutations that might guide targeted non-surgical drug therapeutics.

Advanced imaging, such as vessel wall imaging, and 4D flow MRI is helping us visualize not just the anatomy,

but the underlying vascular physiology and hemodynamics that truly drive disease behavior.

As we look ahead, success isn't just recinalization or nidus obliteration.

It's restoring normal neurodevelopmental growth and function over lifetime.

Our mission is to protect the developing brain through multidisciplinary excellence and collaborative research.

Thank you for your time.

I look forward to ongoing discussions and collaborations.

Thank you you

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
