    Insights

    This study details a rare case of hemicrania continua (HC), a severe headache disorder, that developed after a right internal carotid artery (ICA) dissection. It is the first reported instance of HC secondary to ICA dissection.

    Area of Science:

    • Neurology
    • Vascular Neurology
    • Headache Medicine

    Background:

    • Headache disorders are common neurological conditions.
    • Cervical artery dissection is a potential cause of secondary headaches.
    • Hemicrania continua (HC) is a rare, continuous, one-sided headache disorder.

    Observation:

    • A male patient presented with symptoms consistent with right internal carotid artery (ICA) dissection.
    • Following the dissection, the patient developed a continuous, unilateral headache fulfilling the diagnostic criteria for hemicrania continua (HC).

    Findings:

    • This case represents the first documented instance of hemicrania continua (HC) developing secondary to internal carotid artery (ICA) dissection.
    • The findings suggest a potential etiological link between ICA dissection and the onset of HC.

    Implications:

    • This report expands the known spectrum of secondary headaches associated with cervical artery dissection.
    • Further research is warranted to understand the pathophysiology linking ICA dissection to HC.
    • Clinicians should consider ICA dissection in the differential diagnosis of new-onset HC.

    Transient Ischemic Attack l: Introduction

    A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

    The 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...

    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...
    Hemorrhagic Stroke l: Introduction01:17

    Hemorrhagic Stroke l: Introduction

    A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

    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...

    Increased Intracranial Pressure ll: Pathophysiology

    Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
