    The structure and hemodynamics of arteriovenous malformations of the spinal marrow are first described in the Russian literature on the basis of 93 cases with spinal marrow arteriovenous aneurysms (SMAA) verified by selective spinal angiography. The angiographic pattern of SMAA (their site, blood supply, and ways of outflow) is given in detail. Analysis and clinical tests made it clear that 80% of the patients had subarachnoidal hemorrhage and 60% had recurrent and multiple hemorrhage. Prior to angiography 35 patients had undergone myelography with water soluble contrast agents and 42 had magnetic resonance imaging. Combined vascular lesions in the spinal marrow and other organs were revealed in 20% of the patients. The malformations were divided into 4 types by the angiographic findings of their structure and hemodynamic parameters.

    The Spinal Cord01:54

    The Spinal Cord

    The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

    Spinal Cord: Gross Anatomy

    The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

    Spinal Cord: Cross-sectional Anatomy

    The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

    Central to the gray matter is...
    Anastomoses01:19

    Anastomoses

    In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
    Anastomoses can be formed at arterial, venous, and lymphatic vessels.
    Arterial Anastomosis: These occur between arteries. They are most common in...

    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...

    Cerebral 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...
