A 43-year-old woman presented with a very rare case of hemispheric laminar necrosis as a complication of traumatic carotid-cavernous sinus fistula (CCF). The patient suffered head injury and extensive burns following a car accident. Oral intubation was performed under sedation. When sedation was discontinued 17 days after injury, the patient demonstrated left hemiparesis. Magnetic resonance imaging showed laminar necrosis affecting the right cerebral hemisphere. Angiography revealed a right high-flow direct CCF. Transarterial embolization of the fistula using a detachable balloon achieved complete occlusion of the fistula. However, the left hemiparesis persisted following this intervention. Traumatic CCF may be missed in patients with disturbed consciousness, so clinicians should not overlook possibility of the triad of symptoms of CCF in patients with head injury.

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
