VASCULAR SUPPLY OF THE BRAINSTEM AND ITS CLINICAL SIGNIFICANCE IN ISCHEMIC LESIONS
Keywords:
brainstem, vertebrobasilar system, posterior circulation, ischemic stroke, vascular anatomy, neurological deficitAbstract
The brainstem, consisting of the midbrain, pons, and medulla oblongata, is one of the most vital structures of the central nervous system, integrating motor, sensory, and autonomic functions. Its blood supply is provided by a complex network of arteries derived mainly from the vertebrobasilar system. Even a minor interruption in blood flow to the brainstem may result in severe neurological deficits or death. This study provides an overview of the vascular anatomy of the brainstem and analyzes the clinical significance of its arterial territories in ischemic lesions. The close correlation between vascular topography and clinical manifestations emphasizes the necessity of precise anatomical knowledge for accurate diagnosis and therapeutic intervention in neurovascular diseases.
