What is the success rate of brainstem hemangioma surgery?

The brain is the most important organ in the human body. The activities of the body need to be controlled by the brain. Brainstem hemangioma is also a relatively common intracranial disease. Brainstem hemangioma is very harmful to the body and needs timely treatment. Brainstem hemangioma surgery is a relatively common treatment method. Surgery can repair brain blood vessels. The surgical process needs to be very cautious and the success rate needs to be determined according to the condition.

What is the success rate of brainstem hemangioma surgery?

During the critical period of brainstem tumor surgery, the chances of having a tumor are relatively low. Large hospitals with better maintenance conditions and better surgical techniques can selectively perform brainstem tumor surgery. Benign cavernous hemangiomas, such as angioreticular cell tumors, and gliomas that grow on one side of the brainstem can be treated, but this depends on the indicators of intraoperative brainstem electrophysiological monitoring. During the operation, the anesthesiologist will keep the patient in an anesthetized state, and the monitor will monitor the function of the brainstem. If any brain function abnormalities occur while removing the tumor, the operation will be stopped immediately. For some tumors, such as diffuse, intrinsic, and pontine gliomas, surgery is almost not recommended now. A stereotactic biopsy can be done. Once it is confirmed to be a diffuse glioma of the brainstem, radiotherapy or chemotherapy can be performed, because surgery is really impossible to remove the glioma because the glioma is diffusely distributed and cannot be removed.

1. Causes and common diseases:

1. Congenital theory:

Infant patients and family history support the hypothesis of congenital origin. Recent studies have shown that cavernous hemangioma is an incompletely penetrant autosomal dominant genetic disease, and the gene is located on q11q22 on the long arm of chromosome 7q.

2. Theory of acquired nature:

It is believed that conventional radiotherapy, viral infection, trauma, surgery, and vascular reactions after bleeding can all induce cavernous hemangiomas.

Treatment principles:

1. Conservative observation and treatment:

Some cerebral cavernous hemangiomas are discovered accidentally, and the patients have no clinical symptoms or only mild headaches. Such patients should be treated conservatively.

(II) Microsurgery:

The main purpose of surgery is to reduce or eliminate bleeding and epilepsy, neurological dysfunction, etc. caused by bleeding. In general, patients with clinical symptoms should undergo surgical treatment because their clinical symptoms are caused by bleeding, and patients with a history of bleeding have a significantly increased chance of re-bleeding.

3. Stereotactic radiosurgery:

Stereotactic radiosurgery (SRS), represented by the Gamma Knife, provides an option, but the Gamma Knife treatment of cerebral cavernous hemangioma has always been controversial because there are few literatures that confirm the degree of vascular occlusion after Gamma Knife treatment through pathological changes. All efficacy evaluations are mainly obtained through retrospective analysis, and there are differences in the efficacy evaluation criteria.
