The main cause of brainstem hemorrhage is hypertension, which can lead to hyalinization in the arteries that supply the brainstem, and even the formation of small aneurysms. Under the impact of blood flow, these are prone to rupture, leading to hemorrhage in the brainstem. This is the primary mechanism of onset for brainstem hemorrhage. If the brainstem hemorrhage is caused by hypertension, maintaining good control of blood pressure and keeping it below the ideal level of 140-90 mmHg can prevent frequent recurrence, so there is no need for excessive worry, but it is crucial to monitor blood pressure regularly. Additionally, brainstem hemorrhages can also be caused by other reasons, such as cavernous hemangiomas or arteriovenous malformations. If brainstem hemorrhage is caused by these diseases, and the abnormal vessels are not surgically removed, recurrence is likely. Removing these abnormal vessels can greatly reduce the likelihood of recurrent brainstem hemorrhages.

Can bleeding in the brainstem be saved?

The causes of brainstem hemorrhage can mainly be divided into three categories, The first category is caused by hypertensive factors, which are often the most common cause. The second category is caused by vascular diseases, among which cavernous hemangiomas and arteriovenous fistulas are most common. The third category includes relatively rare diseases, which should not be overlooked in clinical practice, such as tumoral factors. For these, specific examinations must be conducted to accurately determine the cause of the bleeding. Whether treatment is possible depends on the specific circumstances at the time. If the amount of bleeding is relatively small and the area affected is not a critical functional zone, such as the medulla, there is still a possibility of treatment later on. Active surgical and medical treatments can lead to healing later on. However, if the brainstem hemorrhage has already caused cessation of breathing and circulation, generally, there is no need for treatment as such conditions often lead to respiratory and circulatory failure, resulting in death.

Is brainstem hemorrhage dangerous?

The brainstem is the central hub of life in the human body, controlling vital functions such as blood pressure, pulse, respiration, body temperature, and consciousness. Bleeding in this area is extremely dangerous and is a life-threatening condition. Clinically, it has a high mortality and disability rate. For hemorrhages larger than 5 mL, most patients will succumb to central respiratory and circulatory failure within 48 hours. Even if the bleeding is less than 5 mL, although aggressive resuscitation may save the patient's life, most will suffer from severe brain dysfunction such as hemiplegia, aphasia, or a vegetative state. Therefore, brainstem hemorrhage is very dangerous.

How long does it take for a brainstem hemorrhage clot to be absorbed?

In general, the absorption time for a brainstem hemorrhage clot is around two to three weeks. During this period, several phases must be passed, with the two main ones being the rebleeding phase and the brain swelling phase. Rebleeding often occurs within three days after the initial bleeding. If not treated promptly during this time, it can easily lead to further brainstem hemorrhage, increasing the size of the clot and hindering the later absorption process. The second phase is the peak of brain swelling and vasospasm. During this phase, certain substances released during the absorption of blood vessels and clots can cause swelling and spasms of the surrounding tissues. If this phase is also safely navigated, then subsequent absorption tends to be relatively quicker. However, complete absorption generally requires at least two to three weeks.

What should the blood pressure control be for brainstem hemorrhage?

For patients with brainstem hemorrhage, it is important to maintain stable blood pressure after the bleeding. The ideal blood pressure should be controlled between 130/80 and 140/90. This is because the blood pressure should not be controlled too low. If the blood pressure is too low, it can lead to insufficient perfusion pressure in the brain tissue or brainstem, thus exacerbating the state of brain tissue ischemia and hypoxia, which may aggravate the local brainstem ischemia and cause new brainstem infarcts. Additionally, blood pressure should not be too high, as excessively high blood pressure can lead to primary brainstem hemorrhage, coagulation dysfunction, and situations where bleeding is difficult to stop. Moreover, it can cause rebleeding of the brainstem, also known as secondary hemorrhage, which, once it occurs, can be life-threatening for the patient.

Causes of brainstem hemorrhage

The causes of brainstem hemorrhage mainly include the following aspects: The first aspect is hypertension; arteriosclerosis is the most important cause of brainstem hemorrhage because prolonged high blood pressure and continuous impact of blood flow easily lead to damage and disease of the blood vessels, forming small aneurysms. These aneurysms eventually rupture, causing brainstem bleeding. The second aspect is vascular malformations in the brainstem area, which are another major cause of bleeding. Most patients under 40 with normal blood pressure and no coagulation disorders can find vascular malformations in the brainstem area after undergoing DSA examinations following brainstem hemorrhage. The third aspect is heavy drinking leading to increased blood pressure, impaired liver function, abnormal coagulation, etc., ultimately causing bleeding in the brainstem area.
