In clinical practice, the main factor causing brainstem hemorrhage is hypertension. Some secondary factors include diabetes, hyperlipidemia, smoking, drinking, and other unhealthy lifestyle habits. These factors combined can more easily lead to brainstem hemorrhage. Among them, hypertension has the most significant impact. Continuous rise or fluctuation of blood pressure can easily cause vascular fluctuations, especially damaging the inner lining of the vessels and leading to arteriosclerosis. The brainstem is supplied by the basilar artery, and the pontine arteries branch vertically from the brainstem. When blood pressure rises, it seldom reduces the impact on the vessels and can directly cause the vessels to rupture, resulting in bleeding in the brainstem, which is the primary cause. Therefore, it is crucial to strictly control blood pressure in patients with brainstem hemorrhage to reduce the likelihood of recurrence later.
