Abstract:
Spinal arterial vascularization is supplied by a large anastomotic net, making spinal ischemic events far less common than ischemic cerebral strokes. Polycythemia vera, due to blood hyperviscosity and activated platelet aggregation, is associated with a higher risk of arterial and venous thrombotic events. We report a patient with spinal cord transient ischemic attacks, a rarely presenting manifestation, and polycythemia vera, which highlights the thrombotic potential of this disease, and the requirement of exhaustive diagnostic workout of a spinal ischemic event.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
