Stroke is the most common cerebrovascular disease. It occurs when the arteries supplying blood to the brain become blocked, leading to ischemic necrosis of the brain tissue in that region. This results in a series of neurological deficits. Theoretically, once a stroke has occurred, it cannot be completely cured because brain cells are non-regenerative. Once they die, they cannot be revived, and the function of the neurons in that area is completely lost. However, the significance of acute phase treatment lies in the rescue of the ischemic penumbra. The function of these cells can be restored after treatment, and thereafter, they may compensate for the function of the central necrotic area. Thus, patients who receive treatment may regain some neurological functions. Another condition is that the patient must be brought to the hospital within 4.5 hours of the onset of symptoms. If there are no clear contraindications, RT-PA intravenous thrombolytic treatment can be administered. The success rate of this thrombolysis is relatively high, and about 30% of patients may be fully cured without any sequelae.
