Summary
This study presents a rare infant dural arteriovenous fistula case. Transarterial embolization successfully closed the abnormal arteriovenous shunt, resolving the macrocrania.
Area of Science:
- Pediatric Neurology
- Vascular Malformations
- Neurosurgery
Background:
- Dural arteriovenous fistulas (dAVFs) are uncommon vascular malformations.
- Infantile dAVFs present unique diagnostic and therapeutic challenges.
- Progressive macrocrania without hydrocephalus can be a presenting symptom.
Purpose of the Study:
- To report a rare case of dural sinus malformation with dural arteriovenous fistula in an infant.
- To describe the diagnostic findings and successful treatment of this condition.
- To discuss the natural history and management strategies for infantile dAVFs.
Main Methods:
- Case presentation of an infant with progressive macrocrania.
- Diagnostic imaging to identify the dural sinus malformation and arteriovenous fistula.
- Interventional neuroradiology procedure for embolization.
Main Results:
- A high-flow arteriovenous shunt involving the sigmoid sinus and jugular bulb was identified.
- Reflux within the intracranial sinuses was observed.
- Successful occlusion of the arteriovenous fistula was achieved via transarterial embolization.
Conclusions:
- Dural sinus malformations with dural arteriovenous fistulas are rare in infants.
- Transarterial embolization is an effective treatment for such malformations.
- Early diagnosis and intervention are crucial for favorable outcomes in pediatric dAVFs.

01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

01:19Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
