    The most important signs of danger of a headache patient include exceptionally intense or acute headache, transient loss or progressive impairment of consciousness, and neurological deficit symptoms. These patients are referred to an urgent assessment by a physician. Computed tomography scanning of the head is carried out in the case of suspected hemorrhage of a headache patient. Routine diagnosis employing cerebrospinal fluid analysis can be abandoned when excluding subarachnoid hemorrhage in a patient with headache symptoms, if blood is with certainty not observed in the CT scan of the head and no more than six hours have passed after the onset of the symptom. If subarachnoid hemorrhage is detected, cerebral CT angiography will be performed at the same time and a neurosurgeon consulted about the need of operative treatment.

    Veins 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...

    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...

    Epistaxis01:30

    Epistaxis

    Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
    Etiology
    Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
